Indicative of investigations farther afield may be cited the report 

 of F. H. McLearn, 1921, on the Upper Peace River, already referred 

 to in speaking of the Cretaceous of the plains. Time will not permit 

 a review of the work farther west: it must suffice to state that this 

 region likewise has not been neglected and we have to record notable 

 advances in the Mesozoic stratigraphy both in the south and along 

 the line of the National Transcontinental railway. 



Palaeontology 1900 to Present 



We must now review briefly the development of pure palaeon- 

 tology during the two decades we are considering. Dr. J . F. Whiteaves 

 died on the 8th of August, 1909, and palaeontology suffered thereby 

 an irreparable loss. He was succeeded by Dr. Percy E. Raymond as 

 Invertebrate Palaeontologist to the Survey. Dr. Raymond's first 

 report, contained in the Summary Report of the Survey for 1910, 

 while short, is illuminative, for it indicates that Raymond is a field 

 stratigrapher as well as a palaeontologist. The following quotation is 

 typical of Raymond's attitude to palaeontology: 



"Several days were spent in studying the stratigraphy and col- 

 lecting the fossils of the Chazy formation at Aylmer, Ottawa, Gren- 

 ville, Quebec Junction, Bordeaux, and Pointe Claire. These latter 

 studies are still incomplete, but enough facts have been obtained to 

 show that the lower 125 feet of the Chazy formation in the Ottawa 

 valley, as defined in the Geology of Canada, 1863, is of Upper Chazy 

 age, while the black and buff limestones above belong to the Black 

 River group." 



Raymond contributed several purely palaeontological papers 

 dealing more particularly with the detailed anatomy of trilobites and 

 rare forms of echinoderms. In stratigraphie work he subdivided the 

 Beekmantown into Theresa and Beaujiarnois; established the upper 

 age of the Chazy of Ontario and Quebec, calling it the "Aylmer" 

 formation, and subdivided the Black River into Pamelia, Lowvilleand 

 Black River. His work on the Trenton has already been mentioned. 

 An elaboration of his classification with new formational names and 

 descriptions of fossils appeared as Museum Bulletin 31 in 1921. This 

 paper marking a distinct advance in the stratigraphy of the Trenton, 

 discards "Utica" as a formational division but retains the Colling- 

 wood, previously established by Raymond, as a subdivision of the 

 Trenton group. This table is so important that it is reproduced 

 on page 43 but without the correlation given in the original.
