Where on the Internet to find Information on Sir William Edmond Logan, the First Director of the Geological Survey of Canada



“Even at that early period  when every comfort of life was easily accessible, I observed his utter indifference to self-indulgence of any kind, or even such ordinary comforts as most people would be inclined to call indispensable necessities. After an early and very simple breakfast, he would buckle on his instruments, grasp his hammer and with map in hand, march off to the field, in which he would toil on without cessation, without thinking for a moment of food or rest, until the shades of evening gave warning that it was time to retrace his steps towards home, or to seek some temporary dwelling."
       Alexander Murray describing William Logan, as quoted in Harrington (1883, at page 142)

I expect that most readers of this blog will realize that the Geological Survey of Canada was founded in 1842, twenty-five years before Confederation,  that last year – 2017 – was the 175th anniversary of the founding of the Survey, that William E. Logan was appointed the first director of the Survey, and that he is still held in awe by everyone with an interest in Canadian geology.    In large part this is because of his incredible  work ethic, his ability to train and inspire others at the Geological Survey of Canada, “[h]is painstaking methods and wonderful powers of observation and ... his marvelous insight as to the relations of the various series of rocks to one another”  (Robert Bell, 1907).   Those qualities have been remarked on by numerous others, including  Sterry Hunt who commented  “His great merit was the possession of a rare skill in stratigraphy, and an amount of patience, industry and devotion to his work, which has rarely been equalled ...” (Hunt, 1876) and Sidney  Lee, 1893, who commented  “His distinguishing characteristic as a geologist lay in the power he possessed of grappling with the stratigraphy and structure of the most complicated regions.” 

Sir William E. Logan  has been called ‘the father of Canadian science’ (Bryce, 1887;  Lee, 1893)  and ‘the father of Canadian Geology’ (Alcock,  1947, 1948; Smith, 2000).   Bryce, 1887, also called Logan “our greatest scientific Canadian” and this was repeated over a century later when in 1998  Sir William Logan was ranked by Maclean's Magazine as the being the most important Canadian Scientist and the sixth most important Canadian in History.   However, to any Canadian with a background in geology, those accolades understate his worth.   I believe that it is fair to say that without Logan there would have been  no Geological Survey of Canada (or if there had been a geological survey it would have had a short life).   There would have been no geological museum in Montreal (the predecessor of the Canadian Museum of Nature,  the Canadian Museum of History, and Logan Hall).   Elkanah Billings (a lawyer and newspaper editor with an interest in geology and paleontology)  would not have been hired as  the first Paleontologist of the Geological Survey and would not have gone on to identify 1065 new species and 61 new genera.   Dr. James Wilson’s discovery near Perth would not have received early publication as Climactichnites wilsoni.  The trackways found near Beauharnois would not have received such early publication as Protichnites, and it would have been decades before anyone realized that the sandstones at Beauharnois were in a littoral environment.   Would Sterry Hunt, a twenty year old chemist and mineralogist when hired,  have gone on to fame as a petrologist?    Alexander Murray was a naval officer before Logan trained him as a geologist:  Murray went on to head the Geological Survey of Newfoundland.   James Richardson (a  farmer and school teacher) was hired and trained by Logan, and had a long, fruitful career with the Survey.   Logan collected the first meteorite found in Canada and  was the first to attempt a chronological sequence for the precambrian rocks.   Looking back on his life’s work it is hard to believe that  Logan's contributions (discussed further below) were made by one man.

In the year of his passing Ryerson and Hodgins,  1875, started their obituary notice with the statement that Sir William E. Logan, was “one of the most noted geologists of his time, and one to whom Canada owes a debt she perhaps can never repay.  He has accomplished more for her, and won more fame for her, than any other individual in his profession, and has, during a long series of years, done much to introduce her to men of science in Europe, where the Knight was most esteemed.”    Over seventy years later, in a publication to celebrate  the centenary of the Geological Survey, Alcock (1947) stated:

“Sir William Logan was the founder and first director of the Geological Survey of Canada, but he was something more.  For the 27 years of his association with it, he, in his own person, practically constituted the Survey. During that time he built up an organization of enthusiastic assistants, but he himself always remained the most active worker , the guiding spirit, and the one whose passion for research and accomplishment inspired all his associates.  Throughout his lifetime the worth of his character and the value of his contribution  were recognized not only in the country he was serving but everywhere the science of geology was pursued, and the passing time has not dimmed but rather has enhanced his reputation . Wherever more recent workers have followed in his footsteps there has been uniform respect for the conclusions he reached and the work he performed.  It is  small wonder, therefore, that his name is the most prized heritage that the Geological Survey possesses.” 

     

The Essential Online Logan


At the end of this posting  I’ve provided two lists of references that mention Logan:  the first is a list of the papers, books and  web sites that are devoted to or mention Logan that are available online, together with their web addresses;  the second is a list of books and articles that are not freely available online (or that I have not yet read).   The first list also includes the YouTube reference for the 1942 documentary film produced by the National Film Board on the Centenary of the Geological Survey of Canada, and doctoral theses by Rygel (2005) and by Shipley (2007) . 

I have tried to select from the first list the most informative books and articles that are available online that I believe that one should read to acquire a working knowledge of Logan.   I had wanted only to select three to five books or articles, but couldn’t do it, as many excellent authors have written on Logan.   Below is my list of the essential online books and articles on Logan that everyone should read.

I expect that Harrington’s biography on Logan would be everyone’s first choice:

Of those it is only Robert Bell’s 1870 paper and Geikie’s obituary notice that most fans of Sir William Logan will have overlooked.   

In my two lists I have included references to some of Logan’s papers, his notebooks and his journals; it is not close to being exhaustive.  I’ve included a few of his journals as it is in these that one gets an appreciation of his sense of humor.  His notebooks are worth a quick look to get an appreciation of his drawing skills.

To compile a fairly complete list of Sir William Edmond Logan’s papers  see both:  Nickles, John M., 1923.  Geologic Literature on North America, 1785-1918, Part I, Bibliography.  United States Geological Survey Bulletin 746,  at pages 671-672

https://archive.org/stream/cu31924032392486#page/n245/mode/1up/search/logan

In my first list I have included references to books by Lyell, Dana, Geikie, De la Beche (pronounced Beach; who knew?),  Murchison, and Walcott – all leading geologists whose careers overlapped Logan – and provide the page numbers that mention Logan by name.  I did this in order to show the esteem  with which he was held by his contemporaries.   Worth particular notice is that  Sir Roderick Impey Murchison dedicated the fourth edition (1867) of his book Siluria to Sir William Logan, commenting  “To Sir William Logan, LL.D., F.R.S., F.G.S., Director-General of the Geological Survey of Canada. ... I now dedicate this Volume to the Geologist who has not only applied my classification to the vast regions of British North America, but has taught us by his recent important researches that the Laurentian Rocks constitute the foundation of all Palaeozoic deposits in the crust of the Globe, wherever their Foundations are known.”

In my first list I have also included a fair number of obituary notices.    I did this not because this might be the only topic on Logan upon which no one else has written, but because they show that Sir William Logan was genuinely liked and respected by his contemporaries, and had a sense of humour.  For example, the Obituary Notice of  Sir William Edmond Logan that appears in the Proceedings of the Royal Society of London concludes with  "... no man was ever more esteemed and beloved by a numerous circle of friends" (Anonymous, 1876a)  while Sir Archibald Geikie (1875) started his notice with “By the death of this illustrious geologist and most genial man, science has been deprived of one of her bravest and best soldiers, while those  who personally knew him have lost a true, warm-hearted friend.” and concluded his notice by saying  “By those who were privileged with his friendship, Sir William Logan will be affectionately remembered as a frank, earnest, simple-hearted man, ever gentle and helpful, enthusiastically devoted to his profession, and never happier than when discussing geological questions in a tête-à-tête, full of quiet humour, too, and showing by many a playful sally in the midst of his more serious talk, the geniality and brightness of his sunny nature. Peace  to his memory!”  I also compared the notices of Sir William Logan’s passing with obituary notices for other geologists and fellows of British scientific societies that passed away in the same year.  Most notices for others recite the deceased’s scientific accomplishments and fail to remark on the deceased’s personality.

Logan’s contemporaries also spoke highly of him during his lifetime.   Sandford Fleming, 1856,  in a  speech  read  before the Canadian Institute, summarized Sir William Logan’s career to that point in time, complimenting each aspect of his career.   G. W. Allan,  1859, in the President’s Address read before the Canadian Institute, commented “In geological science, Canada, thanks to the labours of Sir William Logan and his able coadjutors, must always hold a place of honor.  It  may safely be asserted that the geological survey has done more for the reputation of Canada among intelligent and scientific men abroad and in England, than anything else connected with the country.”  Lareau (1874) commented “Sir William Edmond Logan a dirigé l'exploration géologique dn Canada depuis 1842. La réputation qu'il s'est acquise dans cette étude, ses connaissances variées, la facilité laquelle il écrit sur des sujets scientifiques, l’amabilité de ses manièrs, la simplicité de ses gouts et les services qu’il a redus au pays lui donnent un rang distingué parmi nos célébrités contemporaines.”   Robert Bell (1870) on the occasion of Sir William Logan’s retirement from the Directorship of the Geological Survey at age seventy-two, commented:   “To say that Sir William Logan is a very popular man would not be doing him justice.  The feeling of all classes towards him would be expressed by saying that he is a favorite of the public.  ...  In taking leave of his responsible office, he does so without having a single enemy, which we imagine cannot be said of any other public man.”   It is worth noting that those last comments are by a person who had just been passed over by Logan for the directorship of the Survey.

Sir William Logan’s Most Important Contributions and Accomplishments


Sir Archibald Geikie (1875), I believe, sums up many people’s view of Logan: “He has done a great work in his time, and has left a name and an example to be cherished among the honoured possessions of geology.”   Here is a list of what I believe to be Sir William Logan’s more important contributions and accomplishments, which I’ve tried to arrange chronologically.   (The volume of text devoted to each item does not reflect its importance.)  

A)  THEORY FOR THE FORMATION OF COAL  - Logan was the first to demonstrate that the stratum of clay that underlies coal-beds was the soil in which the vegetation grew.   North (1932) comments that “Logan noticed that, almost invariably, the coal seams of South Wales rested upon an underclay characterized by the presence of fossils known as Stigmaria, and differing considerably from the shales with leaf impressions that usually occur above the coal. ... he concluded that plants were in situ, and suggested that the coal seams themselves represented material that had accumulated in situ–that is where the trees from which it was derived had actually been growing, and did not represent vegetable matter drifted into estuaries or even into the sea itself.”   This is Logan’s contribution that appears to have generated the most praise during  his lifetime and afterwards. In the 1856 speech awarding the Wollaston Medal to Sir William Logan, the President of the Geological Society of London devoted two paragraphs to describing Logan’s observations on coal.  Nineteen years later Sir Archibald Geikie commented  “The value of this contribution to our knowledge of the history of coal and the changes in physical geography to which the stratified rocks bear witness, can hardly be over-estimated.” [Geikie, 1875, obituary notice in Nature].  An anonymous writer of another obituary notice commented  “Looking back, after a lapse of forty years, we are astonished at the brilliance of Logan’s early deduction, which served to throw so clear a light upon the nature and origin of coal, and entitles its author to our highest esteem as a most careful and accurate observer    [see: Anonymous 1875, obituary notice in The Geological Magazine]”.

B)  GEOLOGIC MAP OF WALES:  Logan’s geologic map of part of Wales was adopted by the Geological Survey of Great Britain, without changes.   Logan’s map was exhibited by him in 1837 before the British Association for the Advancement of Science.    In a letter date April 4, 1842 discussing the subject of William Logan’s qualifications to undertake the Geological examination of Canada, and written in support of William Logan, Sir. H. T. De la Beche, Director of the Geological Survey of Great Britain, commented:  “The work on this district being of an order so greatly superior to that usual with geologists, and corresponding in the minuteness and accuracy with the maps and sections executed by the Ordinance Geological Survey, we felt desirous of availing ourselves of it, when Mr. Logan most handsomely placed it at our disposal.  Having verified this work with great care, we find it so excellent that we shall adopt it for that part of the country to which it relates.”  (See Anonymous, 1846 for the letter; see Logan and De la Beche, 1844 for the map).   W. E. Logan is named as co-author of four early British Geological Maps for Wales, namely Old Series No. 36,  37, 41, and 42S.W., and is given credit for mapping the coal measures shown on those maps.

C)  HORIZONTAL SECTIONS TO TRUE SCALE:  Logan  introduced the practice of drawing, horizontal sections to true scale (six inches to the mile), which was adopted by the Geological Survey of Great Britain (North, 1932).  Zeller and Branagan, 1993, note that  “Logan made a major contribution to survey methods by using chain, theodolite and level to obtain topographical detail so that detailed cross-sections at a scale of 6 inches to a mile could be drawn." Sir Archibald Geikie, 1895, noted that “These sections formed as novel a feature as the detailed maps in the progress of geological surveying. They had been constructed by Logan in Wales, in order to represent accurately the structure of the great South Welsh coal-field. ... The sections were on a true scale, vertical as well as horizontal.  By carefully chaining and levelling, the topography of the ground was represented correctly, and for the first  time the relations between surface-features and underground structure were clearly brought out.”  Winder, 2003, commented that this “allowed predictions about the depths of mines and the discovery of coal seams that were not exposed at the surface.”  Sanford Fleming (1856) stated of Logan’s geologic map and sections of the Welsh coal field that Logan’s work “has been declared by the first scientific men of Europe, to be ‘unrivalled in its time, and never surpassed since.’”

D) OBSERVATIONS ON THE EFFECT OF  ICE IN THE ST. LAWRENCE:  In 1842 Logan presented a paper to the Geological Society of London in which he described the tremendous forces exerted by ice in the River Saint  Lawrence.    Sanford Fleming (1856, pages 239-240)  commented that “The principles laid down in this latter paper appeared so indisputable to Mr. Stephenson, the eminent engineer, that he has been materially guided by it in reference to the construction and site of the great Victoria Bridge” a railway bridge built over the St. Lawrence River.     Frederick N. Boxer, in a book describing the construction of the Victoria Bridge mentions (at page 28) “To William E. Logan was Mr. Stephenson indebted for his first ideas of the probable effect of the pressure of the ice against piers”, includes a long extract from Logan’s paper, and includes an extract from a letter Mr. Stephenson had written in 1854 in which he states “To this memoir [Logan’s Paper] I am much indebted for a clear comprehension of the formidable tumult that takes place at different times amongst the huge masses of ice on the surface of the river, and which must strike the eye as if irresistible forces were in operation, or such as, at all events, would put all calculations in defiance.”
   
E)  FIRST REPORT OF FOOTPRINTS IN CARBONIFEROUS ROCKS:   In  1842 Logan delivered a paper to the Geological Society of London reporting on his 1841 investigations of the coal fields of Pennsylvania and Nova Scotia.   Two identical reports of his paper mention that at Horton Bluff, Nova Scotia  he“obtained a slab which appears to him to exhibit foot-prints”.  In the report  Logan suggested the rocks were Triassic. Sir Roderick Impey Murchison (1843)  suggested that Logan’s slab belonged not in the Triassic but in the Permian.  Charles Lyell  was the first to assign the rocks of Logan’s find a Carboniferous age, in a paper read May 10, 1843 before the Geological Society of London  dealing with the coal formation of Nova Scotia , identical reports of which appeared in five scientific journals.   All five reports of Lyell’s paper mention that at Horton’s Bluff “Mr. Logan discovered footsteps which appear to Mr. Owen to belong to some unknown species of reptile, constituting the first indications of the reptilian class known in the carboniferous rocks.”

Today  William Logan’s discovery of foot-prints at Horton Bluff is acknowledged as important.   In a recent text book on trace fossils, Pemberton et al. (2006, at page 16) mention that Sir William Logan “provided the first demonstration of the existence of land animals in the Upper Paleozoic, when he described the first ever traces observed of land animals from the Carboniferous System. The trace consisted of a series of small, but well-marked footprints, found in the lower coal measures of Horton Bluff, Nova Scotia (Logan, 1842)”.  An Ichnology Newsletter (2001, Issue 23,  Page 33) mentions that “At Horton Bluff (near Windsor, Nova Scotia) he [i.e., Logan] found tetrapod footprints preserved in nonmarine strata. These tracks provided key evidence for the existence of Carboniferous air-breathing organisms...”.    Cotton, Hunt and Cotton (1995, at page 201) note that Logan’s tracks were initially stated to be reptilian, and that “Although these impressions were later determined to be of amphibian origin, these Mississippian tracks constituted the first evidence of tetrapods prior to the Permian.”  
   
Logan’s discovery has also been heralded as the “dawn of vertebrate palaeontology in Canada” by Lambe (1905) who noted that “The discovery by Sir William Logan of footprints at Horton Bluff in 1841 was the proof of the existence of Carboniferous air-breathing vertebrates.”  Mansky, Lucas,  Spielman, and Hunt, (2012) mention that “Horton Bluff, on the northern coast of Nova Scotia, eastern Canada, occupies an important place in the history of ichnology. For here in 1841, Canadian geologist W.E. Logan found the first Carboniferous tetrapod footprints ever discovered, heralding Nova Scotia as yielding the most substantial Carboniferous track record in the world ... The outcrops of the Horton Bluff Formation at Blue Beach are now known to produce one of the most important fossil records, including diverse continental vertebrate and invertebrate trace fossils, a terrestrial flora representing some of the earliest forests, and a diverse vertebrate fauna of Early Carboniferous fishes and tetrapods and a few small non-marine invertebrates.” [Citations Omitted]     

The Canadian Museum of Nature has in its collection William Logan’s specimen from Horton’s Bluff.    The tracks are now considered to be undertracks, and likely represent portions of two sets of tracks (that are side by side) rather than a set left by one tetrapod.

F)  JOGGINS MEASURED SECTION
:   In 1843  Logan spent five days measuring 14, 570 feet  of strata exposed along the shore of the Bay of Fundy.   His report included detailed descriptions and measurements and took  65 pages of text when included as an appendix to Logan’s  annual report.   John William Dawson (1855), in his text Acadian Geology, called it “a remarkable monument to [Logan’s] industry and powers of observation.”  Sandford Fleming (1856, at page 240) states that this was “a  work acknowledged to be one of the most important in American geology, as the key to the structure of the eastern coal basin”.  Recently,  Rygel  and  Shipley,  2005, stated that “it remains one of the single greatest contributions to the geology of the Maritimes.”   What is particularly impressive is that in 1843  Nova Scotia was not part of Canada, and Logan measured the section on his way to the Gaspé so that he could better understand the geology of the Maritimes and where to look for coal in the Gaspé.     H. Y. Hind (1865, page 69) made an interesting observation, commenting: “It may surprise some of my readers who are not fond of walking, when I state that Sir William Logan, in 1843, walked nearly the whole way from the Joggins in Nova Scotia, to the boundary of the Carboniferous Series near Bathurst, for the express purpose of examining the rocks exposed on the road to Canada.  In his exploration of Canada he walked probably not less than 25,000 miles, or equal to once round the Earth.”

Interestingly,  William Logan’s Joggins section was republished in 1908 by the Nova Scotia Institute of Science (see Poole, 1908) because “Copies of this section ... cannot now be obtained. Students ask for them and so do others who are attracted to the locality by the present boom in the coal trade and the possibilities of the field whose rocks are so well exposed in the so-called Joggins section.”  The Nova Scotian  Institute of Science to republished Logan's section “verbatim et literatim”– all 65 pages of it.

G)  LOGAN’S WORM TRACKS, GYRICHNITES GASPENSIS: On August 20, 1843  Logan and his assistant collected three large slabs of sandstone, the largest of which weighed about three hundred pounds and measured five feet by four feet eight inches, from a location about 1100 feet above the shoreline of Gaspé Bay, and as their canoe was too narrow for one of the specimens, borrowed a flat from fishermen to get the specimens  back to their tent.   (Harrington, 1883,  page 161; Logan,  1846a, page 98;  Logan, 1863, page 399;  Whiteaves, 1882)   It is hard to comprehend how two people can collect a three hundred pound slab of sandstone that is 1100 feet above the shoreline, carry the specimen down 1100 feet, and on the same day collect two other slabs, and then transport the three specimens by canoe and flat across Gaspé Bay on the Gulf of St. Lawrence.   I expect that many geologists have rolled a three hundred pound boulder down a mountain (the hard part is predicting its course and getting it to stop where you want it to).    Collecting a three hundred pound slab would be an insurmountable task for most people.

H)  OIL SEEPS IN ANTICLINAL STRUCTURES:  Logan is credited with being the first to note and report that oil seeps were located on anticlinal structures, when in his report for 1844 that was published in 1846 he reported on seepages in the Gaspé [Howell, 1934; Hume, 1944; Hughes, 1955;   Logan,  1846a, pages 41-42;  Hunt,  1865;  Logan, 1863, pages 399-403]     While William Logan’s report “was the first statement in regard to the occurrence of petroleum in anticlines,...  a  clear statement of the anticlinal theory was not made until 1861 when T. Sterry Hunt [of the Geological Survey of Canada] set forth his ideas in an address in Montreal on March 1 of that year.” [Hume, 1944]  This was a lecture Sterry Hunt delivered before the Board of Arts of Montreal and which was reported in the Montreal Gazette of March 1, 1861.
               
I)  SKOLITHOS: Samuel S. Haldeman (1840) was the first to report on this trace fossil and gave it the name Skolithos linearus.   James Hall (1847) modified the spelling to Scolithus linearis, changing the spelling from the Greek (Skolithos) to the Latin (Scolithus).   Both Haldeman and Hall considered Skolithos to be a plant–a Fucoid.   William E. Logan  (1852a  at page 200) was the first person to suggest that Skolithos was a worm hole, commenting:  “Mr. Hall and other American geologists include them among the Fucoids of the rock, but they appear to me more like Worm-holes.   In one or two instances I have perceived that the tubes are interrupted in their upward course by a thin layer of sand, of a portion which descends into them and stops them up; and from this it would appear that the cylinders were hollow when the super-incumbent sand was spread over them.”

J)  PROTICHNITES:   Logan collected and publicized the tracks (and noted that they were formed in a  littoral environment) and provided the geology, while Owen named them.  In 1851 Logan took to London a small slab of sandstone and a plaster cast of a 12 ½ foot slab from a quarry on the left bank of the river St. Louis, at the village of Beauharnois.  In 1852 Logan took to London three slabs and 100 casts (in total, about 350 feet of track). One of the slabs, 12 ½ feet in length, and weighing over a ton, was the original of the cast he had taken in 1851.  See Logan 1851, 1852,  1863.

K)   THE SANDSTONES AT BEAUHARNOIS WERE FORMED IN A LITTORAL ENVIRONMENT
.  See Logan 1852, 1860, 1863.
           
L)  FIRST METEORITE COLLECTED IN CANADA:  In 1854 William Logan collected the first meteorite in Canada near Madoc, Ontario.  While Hunt, 1855, mentions  that “A large mass of native iron was found last autumn upon the surface of the earth in the township of Madoc, C.W.; it has been procured by Mr. Logan”,   Weston, 1899 at page 319, states that   “It is probable that this specimen was first found on the surface of a field; but Sir William Logan told me that he found it propping up the corner of a barn, and at once sought the owner of the barn and offered to put a good square stone in its place; the offer was accepted and Sir William immediately had this valuable specimen removed and placed in the museum.”   Plotkin  and Wilson,  2015, in an abstract for their paper, state  that  “October [2014] marked the 160th anniversary of the recovery of the Madoc meteorite, the first meteorite known to Canadian science. The 168-kg [370 pound]  iron was recovered from the eastern Ontario village of Madoc by William Logan of the fledgling Geological Survey of Canada. Promptly placed in the Survey's Ottawa Museum, the meteorite laid the foundations for Canada's National Meteorite Collection. Madoc was exhibited at the Exposition Universelle of 1855 in Paris, where it won awards, and at the Centennial International Exhibition in Philadelphia in 1876. Although early analyses by scientists classified the meteorite as a fine octahedrite [the most common class of iron meteorite, composed primarily of nickeliron alloys], modern analyses reveal it to be a medium octahedrite of Group IIIAB. The large suite of IIIAB irons enables scientists to explore and model the crystallization of metal phases at all depths in the core of an asteroidal parent body.”  In their paper they mention “ Madoc holds the distinct honour of not only being the first meteorite recovered for science in Canada, but also of being Canada’s largest and heaviest individual meteorite ever to have been found.”
   
M)  CARTOGRAPHER: One of  William Logan’s accomplishments that particularly impressed British geologists was that while they could plot their geologic maps on accurate topographic maps, Logan had to first construct a map or correct errors in an underlying map before he could plot the geology.   The London Times in the summer of  1862 commented on Logan that  “Not having the advantage of an accurate map of the country... he has been obliged to make a topographical survey pari passu  with a geological one.  Few persons can imagine the arduous nature of this work.”   Geikie (1875) commented that William Logan “had to go forth into the forest and ascend unvisited rivers without a track or a map.  He had to make his own map as he went along...”.   Logan’s map making skills were appreciated by Canadians.  The  Canadian Journal, Volume III  (Anonymous, 1855 ), mentions that  “So inaccurate and deficient were the maps of the settled parts that it became necessary to go over the whole ground on foot, and to measure by pacing, the distances travelled.  Mr. Logan pithily observes, that ‘the weariness resulting from attention required to count one’s paces accurately, every day, and all day long, for five or six months, is best understood by those who have made the attempt.’ ”   Robert Bell (1870)  noted that “The Crown Lands Department have admitted that the Geological Survey have done more towards elucidating the geographical features of Canada than their own department, and the cost has been comparably smaller. ... These surveys have been of much use already, and will continue to be of great benefit in the future, in laying off and dividing up new lands for settlement, for defining timber limits, and even for the purposes of the fisheries, as well as in locating roads, railways and canals.”

N)   MAINTAINED FUNDING FROM PARLIAMENT  FOR THE GEOLOGICAL SURVEY OF CANADA.  See Zeller (1987,1991, 1997, 2006, 2007, 2008, 2017), Shipley (2001, 2007)  and numerous others.   Shipley (2001) has stated “Contrary to the expectations of the provincial government in 1842, and to the experiences of the American state surveys, the GSC eventually became a permanent institution. This unlikely achievement has often been seen as Logan’s surpassing accomplishment in his role as Survey director, and has been attributed to his ability to convince both ordinary Canadians and politicians of the value of the Survey’s work.”
       
O)  SUPPLEMENTED THE BUDGET OF THE SURVEY WITH HIS OWN FUNDS.
One Anonymous (1884) reviewer commented that  “[The Parliament of Canada] grudged Mr. Logan the necessary assistance, overlooked the enormous difficulty which the absence of any trustworthy or complete geographical map of the surface imposed – a difficulty aggravated by the extremely defective character of the surveys which had sufficed for such practical purposed as the settlement of townships and the definition of boundaries.   And had not the director been a man of private means and unlimited devotion to his work, the Survey must have broken down at the outset.”    Those comments are  supported by what numerous others  have  written on Logan.   The first grant from Parliament was 1,500 Pounds for two years, at the end of which time William Logan was out of pocket upwards of 800 Pounds (Fleming, 1856).

Robert Bell (1870), on Logan’s retirement,  commented that “The arduous duties from which he has retired have been to him a labor of love.   The salary allowed him by Government, had he accepted it, would have totally inadequate remuneration for a man of his ability and standing. But he has not only worked for little or no pecuniary reward, but has frequently been obliged to advance his private means to a considerable extent, in order to keep up the regular working of the Survey.” ( Worth noting in that quote was “had he accepted it”!)

The extent of Logan’s financial contribution is set out in debates before Parliament in 1881 dealing with a petition requesting that the Museum of the Geological Survey be allowed to stay in Montreal [see Ryan, 1881]. The petition set forth that “Sir William E. Logan has expended out of his own private means to defray the cost of geological explorations, collecting of specimens, wages of assistants, purchase of scientific instruments and books, and for general expenses of the survey, as appears by his books of account, as sum of about $20,000, in addition to many other considerable items of expenditure within the knowledge of the petititioners, but which were not entered in the said books of account.  ... That he also erected a building in St. James Street, Montreal...   mainly for the accommodation of the survey for offices of the director and his assistant, and to afford additional space necessary for the display of specimens in the Museum; the said building costing a sum of $30,000, and for the occupation of which the Government were charged the nominal rent of $1,200 per annum.”    Harrington (1876 ) notes that this rent was “about half the amount which he could have obtained from other tenants.”

P)  LOGAN’S LINE:    “Logan’s Line, also called Logan’s Fault, in geology, prominent zone of thrust faulting in northeastern and eastern North America related to the culmination of the Taconic orogeny during the Ordovician Period (488.3 million to 443.7 million years ago). The zone parallels the coast of Newfoundland, follows the St. Lawrence valley, trends south following the Hudson valley to Kingston, New York, and southwest across Pennsylvania. [Encylcopedia Britannica: https://www.britannica.com/place/Logans-Line ]”   It is named after William E. Logan who first noted a significant break in the faunal record of the Taconic foreland between his Quebec Group and Ordovician shales, and  that rocks of the Quebec Group lay above younger rocks ( See Logan, 1861a, 1861b; Alcock, 1945).  Logan (1861a) proposed that strata was “brought to the surface by an overturn anticlinal fold with a crack and a great dislocation running along the summit, by which the Quebec group is brought to overlap the Hudson River formation.  Sometimes it may overly the overturned Utica formation...   A series of such dislocations traverses eastern North America from Alabama to Canada.”  Logan (1861b) proposed that “Without enquiring into the origin of the forces which have produced the corrugations of the earth's crust, we may suppose that if a sufficient lateral pressure were applied to strata thus accumulated and arranged, there would result a set of parallel folds and overlaps, running in a direction at right angles to that of the pressure, with prevailing overturn dips in the direction of movement ; the greater strength, however, of the solid crystalline gneiss in this particular case, offering more resistance than the newer strata, would cause a break coinciding with the inclined plane at the junction of the gneiss and Quebec group ; the strata of this group pushed up the slope would raise and fracture the strata of the formations above, and be ultimately forced into an overlap of that portion resting on the higher terrace, after probably thrusting over to an inverted dip that part of the upper beds with which they came in contact. The strata of the upper terrace, relieved from pressure by the break, would remain comparatively quiescent, and thus the limit of the more corrugated area would coincide with the slope between the deep and shallow water of the Potsdam period. But the resistance offered by the gneiss would not merely limit the main disturbances, it would probably also guide or modify in some degree the whole series of parallel corrugations, and thus act as one of the causes giving a direction to the Appalachian chain of mountains.”
   
Q)  THE FIRST TO ATTEMPT A CHRONOLOGICAL SEQUENCE FOR THE PRECAMBRIAN ROCKS.   Clark,  1897, in a summary of Geikie’s 1897 talk ‘The Founders of Geology’ mentions  “Some study had already been given to these old rocks, but Logan was the first to attempt to establish a chronological sequence among them.  To him we owe the names Laurentian and Huronian, and although his results have been modified by subsequent observers his work marks a distinct advance in this field of stratigraphical geology.” 

R)   CURATED CANADA’S ROCK AND MINERAL COLLECTIONS AT THE EXPOSITIONS IN LONDON AND PARIS.    These exhibitions generated favourable international press for both Logan and Canada.   Zeller (1991 ) notes that Logan’s “Canadian mineral exhibit for the Crystal Palace Exhibition of 1851 won lavish praise,  and helped the GSC to survive a parliamentary inquiry in 1854 which completely accepted his defence of geology as a guard against pointless searches for coal in the province. A repeat performance at the Paris Exposition of 1855 earned him a knighthood, the Wollaston Medal of the Geological Society of London, and induction into the French Legion of Honour.”    In an obituary notice Ryerson and Hodgins  1875 comment that  “Sir William E. Logan, F.R.C.S., F.R.S.,  for years (says the Hamilton Times ) one of the most noted geologists of his time, and one to whom Canada owes a debt she perhaps can never repay.  He has accomplished more for her, and won more fame for her, than any other individual in his profession, and has, during a long series of years, done much to introduce her to men of science in Europe, where the Knight was most esteemed.”
   
S)  AWARDED THE WOLLASTON MEDAL BY THE GEOLOGICAL SOCIETY OF LONDON.   The Wollaston Medal was awarded in 1856 by the Geological Society of London [See Anonymous, 1856a].   This is the highest award granted by the Geological Society of London.   Other notable recipients were 1836 Louis Agassiz, 1838 Richard Owen,1842 Leopold von Buch, 1848 William Buckland, 1849 Joseph Prestwich, 1851 Adam Sedgwick, 1857 Joachim Barrande, 1859 Charles Darwin, 1864 Roderick Murchison, 1866 Charles Lyell, 1872 James Dwight Dana, 1899 Charles Lapworth, 1918 Charles Doolittle Walcott.

T)  FIRST CANADIAN BORN PERSON TO BE KNIGHTED.            

U)  CLIMACTICHNITES - first to write on; named the trace fossil, correctly identified tracemaker as a mollusk (Logan, 1860, 1863).

V)  EOZOON CANADENSE - This ‘fossil’ is reputed to have generated more papers and discussion on the origin of life in the Precambrian than any other.   While in Logan’s and Dawson’s time the weight of authority was against it being organic, work in the early 1980's by Marika S. Bourque and other members of the Ontario Geological Survey recognized the Huntingdon type Eozoon, namely quartz bands alternating with bands of tremolite and calcite, from a few miles southeast of Madoc, and found in surrounding townships, as being of biogenic origin– silicified and recrystallized  algal colonies:  an algal-laminate stromatolite.    (See my April 29, 2016  blog posting entitled ‘A specimen of Eozoon Canadense at the Matheson House Museum in Perth, Ontario’ for a discussion of the controversy.)

W)  GEOLOGY OF CANADA, 1863.   Wikipedia mentions that “One of the most important accomplishments of the GSC under Logan was the publication in 1863 of the Geology of Canada. Representing all the work of the organization up to that date, this 983-page book recorded everything known about Canadian geology. It received national and international acclaim for its content, style, and precision. ...  In 2005, the Literary Review of Canada chose Logan’s landmark publication Geological Survey of Canada: Report of Progress from its Commencement to 1863 as one of the 100 most important Canadian books. The list was intended to identify the books that had “changed our country’s psychic landscape.” [https://en.wikipedia.org/wiki/William_Edmond_Logan ]  In 1881, in a talk delivered to the Ottawa Field-Naturalists' Club, Alfred K. C. Selwyn, then director of the Geological Survey of Canada, said of the Geology of Canada that “Whether regarded from an economic or from a scientific standpoint, this great work of Sir W. Logan and his colleagues must be considered a priceless gift to Canadian Geologists.” ...[and that] it contains a mass of information, scientific and practical, which, however much future researches may enable us to supplement it, will always remain as a solid foundation on which the superstructure of Canadian geology must be built by succeeding generations.”    Professor Harrington of McGill stated  (1883, at page 351) that “although published nearly twenty years ago, it remains to-day the most valuable book of reference on the geology and mineralogy of the provinces of Ontario and Quebec. Clear, sufficiently full and not overburdened with details, accurate in its descriptions and wonderfully free from typographical errors, the purely scientific portion evenly balanced by a proper allowance of economic geology, it was altogether a model report.”   Shipley (2001) has stated that Geology of Canada is “arguably the pinnacle of Canadian scientific publishing in the nineteenth century” and notes that “The work emerged partly despite... repeated financial crises– Logan had to purchase $3,000 worth of type for the volume himself.”

X)  GEOLOGICAL MAPS OF CANADA, that included the adjoining British Provinces and the North-eastern United States.    Logan produced the first such maps. Hitchcock, 1877, commented that “The finest of all our American maps is that published by the Government of Canada in 1869 (dated 1866). ” 

Y)   THE GEOLOGICAL SURVEY OF CANADA’S LIBRARY: This was started  by  Sir William Logan who left the whole of his library to the Survey when he retired  (Selwyn,1877, page 7).   "The Geological Survey of Canada's library set a pattern followed by other institutions and associations.  Formed principally by one person, Sir William Logan, it contained hundreds and then thousands of periodicals and offprints..." ( Lamonde, Fleming,  and Black, 2005)
   
Z)   ENDOWED THE LOGAN CHAIR IN GEOLOGY AT MCGILL UNIVERSITY IN MONTREAL.  “To Logan also, McGill University owes much ; for, in 1864, he founded and endowed the ‘Logan Gold Medal’  for an honor course in geology and natural science, and, in 1871, gave $19,000, which, together with $1,000 given by his brother, the late Mr. Hart Logan, forms the endowment of the ‘Logan Chair of Geology.’” [Harrington, 1876]

ZA) LEFT FUNDS IN HIS WILL TO  REPLACE SPECIMENS  TAKEN TO OTTAWA.  The Geological Survey of Canada had been headquartered in Montreal since before Confederation. In 1881 the Geological Survey of Canada, the Geological Survey of Canada Museum, and its rock, mineral and fossil collections were moved to Ottawa. Sir William Logan, in his will, had left funds to collect replacement specimens for a museum in Montreal.   The Report on the Peter Redpath Museum of McGill University, No. 11, January, 1883, mentions at page 16 under the heading Part V. - Notice of Collections, Logan Memorial Collection that specimens added to the collection included a "Series of large slabs of Protichnites and Climactichnites, collected by Mr. Richardson, at Perth, Ontario."   These were specimens collected with funds provided in Logan’s will.
   
ZB)  Nevertheless all of those contributions and accomplishments, pale in comparison with his most important contribution and lasting legacy: the Geological Survey of Canada.     Sir Roderick Murchison may have said it best, on the occasion of awarding the Wollaston Palladium Medal to Sir William Logan, when he commented  “I can give no better evidence of the value of this survey and of the manner in which it has been carried on by Sir William Logan than by quoting the testimony of an American writer in Silliman's Journal. It is there stated : ‘No geological survey on this continent has been carried on with more thoroughness and with results of higher importance to the science than those of Canada under the direction of Mr. W. E. Logan. There is great precision in his observations and exactness in his statements.’”   However, the Survey was not just Logan.  He surrounded himself with competent people and inspired them to produce at a high level.   Robert Hall, 1884, stated   “It is quite evident that the practical success of the Survey at home, and its scientific reputation abroad during those early years of its existence, were due to the remarkable zeal and practical common sense of Sir William Logan, and the enthusiasm and esprit de corps which he succeeded in imparting to his colleagues.”+

Logan Hall and the Canadian Museum of History


This past summer I visited Logan Hall, a geological museum on the first floor of the Geological Survey of Canada’s offices at 601 Booth Street in Ottawa, Ontario.   I was glad I did, even if the celebration of 175th anniversary of the founding of the Survey was decidedly muted.  On display were a display on Logan, specimens of Eozoon Canadense and other fossils collected by Logan, together with portraits of Logan and Billings, plus large numbers of minerals, fossils, meteorites and rocks.   However, one would think that sometime within the forty years since I  worked as a summer student for the GSC they could have fixed the building’s air conditioning.  I remarked to the Commissionaire that it was hot in the museum to which he replied “It’s a hot day.”   At least drinking water was available at a water cooler.   I also remarked to the Commissionaire that perhaps they could turn the lights on in the museum, but was told that they couldn’t as that would damage the minerals.   That piqued my interest and I went back in looking for minerals that could be damaged by sunlight!

This fall I borrowed from the public library and  read both Suzanne Zeller’s book ‘Inventing Canada’ and  Charles Smith and Ian Dyck’s annotated book ‘William E. Logan's 1845 Survey of the Upper Ottawa Valley.’  I then visited the Canadian Museum of History in Gatineau, Quebec in part because I wanted to purchase Smith and Dyck’s book from the museum’s gift shop and in part because it had been a while since I last toured the museum.   Again, I was glad I did as the museum has a small display on Sir William Logan that includes his portrait painted by William Sawyer, his Wollaston Medal awarded in 1856 by the Geological Society of London, the Cross of the Legion of Honor  he was awarded by Napoleon III at the Paris Exposition in 1855, and the octant  that Logan was awarded for finishing first in a math class that he took at Edinburgh University.    The labels on all four say that they were donated by the Geological Survey of Canada.   

An Anecdote


As almost everyone who has written on Sir William Logan has included anecdotes about his life, it  would be an oversight to write a blog posting on him without including at least one such anecdote.  I particularly liked this anecdote provided by Alexander Murray:

“I recollect in 1845 while I was in the neighbourhood of Gaspé, being asked by a most respectable person if I knew Mr. Logan, to which having replied in the affirmative, he went on to say – “It was a pity to see a decent-like elderly man going about breaking stones," – and that in his opinion his friends were greatly to blame in  not having him carefully looked after!”

Life of Sir William  Logan. [A review of Harrington’s 1883 Biography on Logan] Saturday Review of Politics, Literature, Science and Art, Volume 57 at pages 389-390 “[The Parliament of Canada] grudged Mr. Logan the necessary assistance, overlooked the enormous difficulty which the absence of any trustworthy or complete geographical map of the surface imposed – a difficulty aggravated by the extremely defective character of the surveys which had sufficed for such practical purposed as the settlement of townships and the definition of boundaries.   And had not the director been a man of private means and unlimited devotion to his work, the Survey must have broken down at the outset.”

Where on the Internet to Find Charles Doolittle Walcott’s Papers on the Cambrian

It is staggering the volume of work that Charles D. Walcott (1850-1927) produced.
       
I was looking for a particular point mentioned by Walcott, had trouble finding it, and decided to compile a list of his papers on the Cambrian so that next time it will be easier to find what I’m looking for.  (Query whether,  having failed to mark the particular paper of interest, I’m any farther ahead?)

I couldn’t leave out a few of Walcott’s other papers that I found particularly interesting or entertaining, and I do not expect my list to contain all of his papers on the Cambrian.

While the Smithsonian published each of Walcott’s papers as individual parts before publishing Cambrian Geology and Paleontology  I, Cambrian Geology and Paleontology II, Cambrian Geology and Paleontology III,   Cambrian Geology and Paleontology IV  and Cambrian Geology and Paleontology V,  I have provided the publication dates for the composite volumes.

Protichnites, etc. on display at the Canadian Museum of Nature’s Collection and Research Facility

On October 14th I attended the open house at the Collections and Research Facility of the Canadian Museum of Nature.   I’m not sure what to consider as the highlight of the visit as there were many interesting things to see.   I enjoyed holding samples of tektite and dinosaur coprolite, and found the explanations on lichen and how exhibits are prepared fascinating.   The laboratory where they were preparing dinosaur fossils was also well worth the visit as were the trays of insects.

Michelle Coyne of the Geological Survey of Canada had on display two of Sir William Logan’s specimens showing Protichnites trackways.   Below are photographs taken on October 14th of the specimens.   The first photo shows a specimen with three trackways including the Protichnites septemnotatus trackway figured and described by Owen (1852).





 The next photo shows two trackways figured and described by Owen (1852): the upper trackway is Protichnites alternans while the lower trackway is Protichnites lineatus.

 The next photo is a closer view of the Protichnites alternans trackway.


The two specimens answer a question that I had concerning the inclusion of Owen’s numbering for the type specimens on Logan’s plates that accompanied Logan’s paper of 1852.   I had wondered whether Owen’s numbering represented the exact location for the specimens pictured in Owen’s plates showing the type specimens, or whether the numbering merely identified the trackway from which Owen had selected a specimen.   It is clear from the holotype specimens that Owen’s numbering on Logan’s plates correspond to the exact location for the specimens pictured in Owen’s plates which formed part of Owen’s paper from 1852.

Things To Do on October 14th

Next Saturday will provide an opportunity for those in the Ottawa area to visit localities of geological interest throughout Ottawa and Gatineau and to visit the collections and research facility of the Canadian Museum of Nature.   

8th Annual Geoheritage Day in the Nation's Capital


On Saturday, October 14, 2017, from  10 am to 3 pm, volunteers from the Department of Earth Sciences at Carleton University and the Ottawa-Gatineau Geoheritage Project will be on hand at six locations to explain interesting features of the local geology.   The locations for this year are:

Champlain Bridge Stromatolites, Gatineau, Quebec
Champlain Lookout, Gatineau Park, Quebec
Hogs Back Falls, Prince of Wales Park, Ottawa
Cardinal Creek Karst, Orleans, Ontario
Pinhey Sand Dunes, Nepean, Ontario

Visit the Collections and Research Facility of the Canadian Museum of Nature

   
I expect that most people living in Eastern Ontario will have visited the Canadian Museum of Nature in downtown Ottawa.  What few people know is that the Canadian Museum of Nature operates a world class collections and research facility across the Ottawa River in Gatineau, Quebec. This research facility houses about 14.6 million specimens and artifacts, but for most of the year is closed to the public.  It is open to the public once a year for self-guided tour of the facility, and this year it is open on Saturday, October 14th from 10 am to 4 pm.

This is a chance to see minerals, meteorites and dinosaur bones; to learn how dinosaur fossils are prepared for study and display; to visit the Herbarium; to see specimens of parasites, crustaceans, mussels, clams, and insects; to visit the DNA lab, Heavy Wet lab and Conservation Lab; and to see special displays from the Bank of Canada Museum and the Geological Survey of Canada.

Details:
- Saturday, October 14, 2017
- 10 am to 4 pm
- free admission
- Canadian Museum of Nature - Natural Heritage Campus
   1740 Pink Road, Gatineau, Quebec
- Parking: Free on site and in the neighbourhood

Further details are available at:
http://nature.ca/en/plan-your-visit/what-see-do/whats/open-house

Below are photographs that I took while at the collections and research facility to look at Sir William Logan’s specimens of Protichnites trackways from Beauharnois with Dr. Robert MacNaughton, Michelle Coyne, Kieran Shepherd and Margaret Currie.






The second last photo shows Logan’s original specimen of Protichnities octo-notatus with a printout of Owen’s plate on top of the specimen.   The last photo shows two parts of the twelve foot specimen of Protichnites from Beauharnois which Sir William Logan took to London in 1852. 

 

Logan’s Worm Tracks: Gyrichnites gaspensis


The following specimen, which shows incredible burrowing, is also interesting.





Margaret Currie brought it down with a fork lift, noted that it lacked documentation and wondered if we had any information.  Dr. MacNaughton (from a drawing in Harrington’s biography of Logan) and Michelle Coyne were able to identify it as a specimen of annelid tracks Sir William Logan had collected in the Gaspé, a GSC type specimen that had been missing for a number of years.  Michelle Coyne was able to provide a reference to a paper by Whiteaves (1882) describing Logan’s specimens and naming the fossil Gyrichnites gaspensis.

A Field Trip to the Ellisville Potsdam Sandstone Quarry

Last Sunday I visited the sandstone quarry at Ellisville, Ontario as part of an annual field trip organized by the Niagara Peninsula Geological Society.  It was sunny with a cool breeze – a perfect day to visit a quarry.

While only a few attended, something of interest was found by everyone.

Miniature Chevron Shaped Sand Dunes

Below is a photograph  of a texture in the sandstone that I’d never seen before, namely miniature chevron shaped sand dunes.


The simplest explanation is that the dunes are wind-generated dunes, with the arms pointing downwind, similar to Barchan dunes that one would see (on a much larger scale) in a desert.  However, I’ve noted references to the formation of chevron shaped dunes in experiments conducted in a water tank, so the chevron shaped dunes in the photograph could be water generated.

The Climactichnites burrowing trace: Climactichnites youngi.

Below are photographs of burrowing in sandstone. At least fifteen separated burrows are visible on the surface of the specimen.   I noted the specimen while walking with Peter Lee of Gananoque and Paul Musiol of Kingston.  I believe that the specimen shows the Climactichnites burrowing trace: Climactichnites youngi.   While not that obvious from the photographs, the burrows appear at a number of different levels in the specimen.


Subsequently Peter Lee found another specimen showing similar burrowing.

The Niagara Peninsula Geological Society may be scheduling another field trip to the quarry this October in conjunction with a trip to the Wollastonite mine along Highway 15 and the Frontenac Lead Mine.   Check their web site  http://www.ccfms.ca/clubs/NPGS/    and Facebook page
https://www.facebook.com/groups/1392693367698780/   for updates.

At the end of this email I’ve provided the dates and titles of my earlier blog postings where I  provided photographs of trace fossils and textures in the sandstone that were found at the Ellisville Quarry.

Abraham, Logan and Owen: The Discovery of the First Protichnites trackways – Part 2

[Part 1 of this article was posted August 29, 2013.]

In 1851 Logan took to London a small slab of sandstone and a plaster cast of a 12 ½ foot slab from a quarry on the left bank of the river St. Louis, at the village of Beauharnois and on April 30, 1851 both he and Professor Owen  read papers before the Geological Society of London.

In 1852 Logan took to London three slabs and 100 casts (in total, about 350 feet of track). One of the slabs, 12 ½ feet in length, was the original of the cast he had taken in 1851.  

In a paper read March 24, 1852 before the Geological Society of London, Logan described the geology of the area and the finding of five new localities of foot-prints.   Two localities were in the vicinity of Beauharnois: the first, in the field of Mr. Henault, a half mile west of the quarry in which the first impressions were discovered; the second, two and a half miles further west at the mouth of the Beauharnois Canal.   The other three new locations were in the vicinity of Point Cavagnol (about 15 miles west of the first locality – the quarry in the village of Beauharnois); on the  Island of St. Généviève in the St. Lawrence River, south of Montreal Island (about 7 miles north of the village of Beauharnois); and on the Riviere du Nord, at Lachute,  in the Seignory of Argenteuil (about 35 miles north east of the first locality).
               
In a paper also read March 24, 1852 before the Geological Society of London, Professor Owen (1852) described and named six tracks, stating that he had selected from the casts and slabs that Logan had brought to London “the best marked and most intelligible portions for [his] descriptions.”    Logan (1863) noted that in view of the “various differences in the tracks, Professor Owen has given separate specific provisional names to several of them, not for the purpose of indicating a positive specific difference in the animals which have impressed them, but for the convenience of reference.”  Professor Owen distinguished between two different genera and four different species.

The six tracks that were named by Professor Owen and which in his paper were accompanied by plates showing the tracks, follow:

1.  Protichnites septem-notatus    Plate IX
2.  Protichnites  octo-notatus      Plate X
3.  Protichnites  latus      Plate XI
4.  Protichnites  multinotatus   Plate XII
5.  Protichnites  lineatus     Plate XIII                   
6.  Protichnites  alternans     Plate XIV

Copies of those six plates form part of my March 7, 2014 blog posting.  They are shown together below.



Five of those named tracks came from Mr. Henault’s field.  The sixth,  Protichnites  multinotatus, came from near the first one discovered, namely the track at the quarry on the St. Louis River at the village of Beauharnois.

Professor Owen included a seventh plate, Plate XIV.A, remarking that it is for a slab  “the casts of which were first brought over by Mr. Logan during the preceding year.”   Plate XIV.A therefore shows part of the original 12 ½ foot specimen described by Logan (1851) and Owen (1851) and taken to London in 1852.  It is shown below.




To understand why Professor Owen named six tracks it helps to translate the Latin names (provided in Billings, 1857) and to consider part of his Owen’s description:

1.  Protichnites septem-notatus   -   seven marked  - a repeating pattern of fourteen impressions of footprints, seven on the left of the medial line and seven on the right
2.  Protichnites  octo-notatus - eight marked  - a repeating pattern of sixteen impressions of footprints, eight on the left of the medial line and eight on the right
3.  Protichnites  latus    - broad  - “the impressions of the feet are deeper and larger”, the track would seem to have been made “by a different species having a body broader in proportion to its length
4.  Protichnites  multinotatus  - many marked  - “ a strong deviation of the intermediate groove from the mid-line between the two lateral series of impressions”
5.  Protichnites  lineatus - linear - the median “impression preserves in some parts... a considerable and equal depth; ... the lateral impressions... are represented by continuous grooves rather than by a succession of pits.”                
6.  Protichites  alternans  - alternate - “the opposite impressions of the series are not symmetrical; for where the impressions are widest apart on the left, those on the right...are nearest together... These impressions indicate a waddling gait, or an alternate oblique movement side to side...”.

It is also helpful to consider the following drawing of Protichnites septem-notatus  from Owen (1860) where he has circled the repeating sets of seven footprints.






While Owen (1852) described the tracks in detail, I find his descriptions hard to follow.  The best description is by Logan (1852b at pages 10 - 12):

“The track and footsteps, when the specimens are most perfect, in general present a median groove  more or less flat, and of different proportionate widths in different specimens, with a number of footprints on each side in answering pairs; certain sets or numbers of these answering pairs have homologous repetitions throughout the whole length of the track, as if they were the result of successive applications of the same impressing instruments, and the numbers of answering pairs in the homologues of different tracks are sometimes different, constituting something which may be considered analogous to difference of species. The homologues  in different tracks appear to have sometimes seven and sometimes eight answering pairs of pits, and it is difficult to say whether the pits are to be taken as  impressed by the extremities of so many legs, thus giving the animal fourteen legs in the one case, and sixteen in the other, or whether some of the impressing points are to be grouped in twos or threes, .... The median groove in most of the tracks is so uniformly in the middle between the footprints, as to favor the supposition that it may be occasioned by the effect of an immoveable breastplate or plastron, but in one remarkable instance, at a bend in the track, the groove gradually leaves the middle, and while it seems impressed with more than usual force, approaches and partially obliterates the footprints on the convex side, as if the impressing part had been the extremity of a tail, which, when the body turned to one side, interfered with the footprints in the rear, on the other. A feature common to all the grooves is, that each repetition or homologue of the footprints is accompanied with a deepening and shallowing of the groove, giving it the appearance of a chain of shallow troughs, which, when the impression is light, are separated from one another by intervals of the ungrooved surface. The groove is often but faintly indicated, and occasionally it is not perceptible; and frequently it happens when this occurs, that the footprints are stronger and deeper than when the groove is more conspicuously impressed. In some of the tracks, while the groove is straight, the exterior limits of the footprints offer a congeries of segments of a circle, convex on the outside, but those on opposite sides of the groove alternate, the segment on the one side, starting from the middle of the segment on the other, and giving to the whole series of footprints in the track a serpentining course, as if the animal had waddled in its gait. In one of the tracks there are three narrow grooves instead of footprints on each side, of the main one, for a certain distance, as if the limbs of the animal had been dragged along the bottom, while the body was afloat. ...  The generic term for the whole is Protichnites, and the specific names are, P. septemnotus., P. octonotatus, P. multinotatus,  P. alterans,  P. lineatus.”


A Plan of Mr. Henault’s Field at Beauharnois


   
Logan (1852) included a plan of Mr. Henault’s field at Beauharnois, the source for five of the six Protichnites specimens figured by Owen (1852).   Below is an edited version of Logan’s plan of the field.


Note that the scale is in chains (1 chain = 22 yards = 66 feet = 20.1 Meters); that the plan shows the direction of ripple marks on the bedding;  that I’ve shown the tracks in magenta; and that the tracks are on a number of different bedding planes.

Logan (1852) reported  ten tracks in area A, seventeen tracks in area B, six tracks in area C,  and ten tracks in an area that is a few yard to the east of area C.   Within a length of four chains (about 90 yards or 80 meters) Logan found 43 tracks.

All of the 43 tracks were between 4 inches and 6 1/2 inches wide, except for one that was 3/4 of an inch wide.   The longest track is 28 feet six inches long while the shortest was one foot long.  Twenty-six of the tracks from areas A, B and C were on smooth surfaces while seven of the tracks from areas A, B and C were on ripple marked surfaces.  (For the fourth area Logan did not identify the surface.)

Logan (1852) included additional plates showing closeup views of areas A, B and C.  Amended versions showing parts A and B are provided below.  Logan numbered each track on Part A and Part B and in his paper provided the length and width of the tracks.  Logan's plates also included numbers (that I've shown in blue with a blue square) corresponding to Owen's names for the tracks.


The plan of  part A shows the tracks that are  numbers 1, 5 and 6  of Professor Owen’s descriptions, namely:
1.  Protichnites septem-notatus (seven marked)
5.  Protichnites  lineatus (linear) 
6.  Protichnites  alternans (alternate)
For part A, seven of the tracks were on a smooth-surfaced bed, while two of the tracks (Logan's 9 & 10) were on a surface 2 inches lower showing ripple-marks, while the tenth track (Logan's 8) was "on a surface still lower by about 1 inch, but showing no ripple-mark."

The plan of  part B shows the tracks that are  numbers 2  and 3 of Professor Owen’s descriptions, namely:
2.  Protichnites  octo-notatus    (eight marked)
3.  Protichnites  latus    (broad)  
Of the seventeen tracks on part B, twelve tracks are on a smooth surface and five tracks (Logan's 13, 14, 15, 16, 17) are on a ripple marked surface 2 inches below the smooth one.

Logan (1863) provides various measured sections of Potsdam sandstone, including a section from Beauharnois in the vicinity of Henault’s field (1863, pages 105-106), where he describes the beds and indicates where ripple marks, wind marks, Protichnites tracks and Scolithus occur.   Based on his observations,  Logan (1860) suggested that “The crustacean which impressed the tracks at Beauharnois must have been a littoral animal..."   


Additional Locations for Protichnites Trackways Provided by Logan



Subsequent to giving his talks in London, Logan provided other localities where Protichnites tracks were found:

 - Protichnites, at Perth, Ontario in association with Climactichites (Logan, 1863, pages 93 and 107);
- in Lansdowne and Bastard township, Ontario (Logan, 1852b, page 10)
- “about a mile N. W. of Cuthbert's mills on the Chicot there is an exposure of fine grained white sandstone, characterized by Protichnites” (Logan, 1863, page 93);
 - Protichnites, on a peninsula on the north side of the Ottawa River, about seven miles below the mouth of the Petite Nation, (Logan, 1863, page 94);
- in the vicinity of Pointe du Grand Detroit in Vaudreuil, twelve miles west of the locality at the Beauharnois canal (Logan, 1863, page 90);.

Murray (1852, page 67) provides the best description of the tracks from near Pointe du Grand Detroit:

“[A]bout twenty-five acres above the Pointe du Grand Detroit, fine grained white quartzose sandstones were met with in beds of from six inches to two feet thick. Some surfaces displayed ripple-mark, and on one, trails and footprints of a species of animal exist, similar to the tracks occurring at Beauharnois, in the same description of beds. The largest of the tracks measures eight and a-half inches across, and the trail is visible for four feet, and gradually becomes obliterated at end. On the same surface, twenty yards farther up the stream, three additional tracks of the same sort were observed, each-one traversing the other two; two of these measured four inches across, and the third four and a-half inches; the last is distinct for three feet in length, and the other two, one foot eight inches, and one foot three inches respectively. The groove in the middle between the footprints on each side, so frequently seen at Beauharnois, occurs only in one of the smaller trails.”

I have provided  his full description, because most of the tracks were missing the groove in the middle and now would be identified as Diplichnites.

Pointe du Grand Detroit is now better known as Quarry Point and falls in Hudson, Quebec.  The stream that Murray referred to is likely the Vivery River/Vivery Creek.


Additional  reports of Climactichnites and Protichnites Trackways from Beauharnois



Others have reported on Climactichnites and Protichnites trackways from Beauharnois, including
Walcott (1914 at pages 261 and 277 ), who collected specimens from “Rogier’s farm just west of the town of Beauharnois”.    Yochelson and  Fedonkin (1993) mention that  “an exceptionally large slab containing numerous examples of both Climactichnites and Protichnites were collected from ‘a mile west of Beauharnois, Quebec’” by Walcott.   This is the large slab that is the frontispiece to their article and was at the date of their article “on public display off the east side of the Rotunda on the first floor of the National Museum of Natural History, Smithsonian Institution, Washington, DC.”

Clark and Usher (1948) reported that a quarry in Potsdam sandstone at Melocheville, which is about 3 km to the west of the original quarry at Bearharnois, had specimens of Climactichnites exposed on the quarry floor.  

 More recently, Lacelle, Hagadorn and Groulx (2012) reported on Climactichnites and Protichnites  trackways in the Keeseville Formation of the Potsdam sandstone at Beauharnois, together with other trace fossils, from which they concluded that “these fossils were produced in shallow marine to intermittently emergent sand-dominated coastal environments, with tracemakers occupying pools, channels, levees, floodplains, and on windy sand flats.”

Even more recently Splawinski,  Patterson and  Kwiatkowski (2016) reported Diplichnites trackways in the Cairnside formation of the Potsdam sandstone at Beauharnois,  Québec, noting that they found  “sedimentary structures and trace fossils indicative of supratidal, intertidal, and shallow-marine lithofacies.”

Addendum

Briefly Consider the following.

Two Protichnites tracemakers walk into a bar.  One says to the other “I’d lost track of you.”
   
Two Protichnites tracemakers walk into a bar.  One comments on his friends disheveled appearance, and is chastised “What do you expect, I was caught in the Cambrian Explosion!”

Three Protichnites tracemakers walk into a bar.  Two of them should have ducked.

A Protichnites tracemaker walks into a bar, orders a scotch on the rocks, and  the bartender asks  “Any particular kind?”   The tracemaker replies    “Any single malt whisky on quartz arenite– littoral or eolian is fine.   I’m not particular. ” (Is that just being siliclastic?)

What did the Protichnites tracemaker say when it ran into a long lost friend while exploring the eolian sand dunes?  “Long time no sea.”

If a paleontologist gives a talk commenting on Logan’s Holmesian reasoning in deducing that Protichnites tracemakers inhabited tidal flats, should the paleontologist conclude with the statement  “Sedimentary my dear Watson”?

Why is it hard to interview a Protichnites tracemaker?  All they want to do is make tracks.

Ichnologists are dogmatic.  It’s as if everything is written in stone.

Did you hear about the absent minded Ichnologist that was studying Protichnites?  He  kept getting off track.
       
Sir William E. Logan was a great fiction writer.   The problem is that everyone takes him littorally.

The theory that the Protichnites tracemaker was a trilobite is not that far fetched.  It should get equal Billings.

Did you hear about the  Protichnites tracemaker that was tired of sleeping on sand?  He bought a Walcott?

 Do Protichnites tracemakers  travel light because they don't Owen anything?

Did you hear that Protichnites tracemakers went on strike for equal treatment with Climactichnites tracemakers?   They wanted a resting trace.

When the Protichnites tracemaker asked the Climactichnites tracemaker why it didn’t venture inland, the Climactichnites tracemaker responded  “Tidal flat.  Sand dune hilly.”

Did you hear about the Euthycarcinoid that disappeared without a trace?  Probably not.
   
Did you hear about the  Protichnites tracemaker that was always contradicting itself?  Kept saying “That’s not what I sediment.”

Why don’t Protichnites tracemakers commit crimes?  They’re easy to track down.   

Did you hear about the foolish Euthycarcinoid that robbed a bank?   The police were able to trace the funds.

Did you hear about the Euthycarcinoid that was born on the wrong side of the tracks? He made good.

Protichnites tracemakers were too vain to hang out with Trilobites.  They didn’t want to become dated.       

If a fossil is defined as a markedly outdated or old-fashioned person or thing, why does the study of Ichnology never get old?
