section at this point is not more thaa 150 feet thick, and the fossiliferous stratum occurs at 

 about eight and a half feet below the surface, (»,113B). The matrix is a very hard, bluish,, 

 sandy clay through which stones of all sizes are scattered, and it shows a very rough and 

 tumultuous deposit (**,140B). 



Almost nothing is known respecting the flora of Coal brook, the only records being 

 those of Sir William Dawson (21, 186 B) who recorded in 1877 the occurrence of Populus 

 arctica, Heer, P. laioir, Heer and P. subrotundus, Lesq., with a possible Sorbus. In 1882 

 (22, 34) he repeated this list, showing that nothing had been added in the meantime, and 

 that it represents the present state of our knowledge, with the exception that in 1894 he again 

 observed the occurrence of Populus arctica, added Populus genatrix, Newb., and also recorded 

 the presence of a Rhus, possibly R. rosos/olia, Lesq. 



He observes that " the leaves from this place are in a matrix of grey, arenaceous shale, 

 and are almost exclusively poplars." 



Although he found it almost impossible to base any final conclusions upon such scanty 

 information, he nevertheless concluded that " there can be no doubt, however, that they 

 belong to the Tertiary period, and that they may be somewhat newer than the Laramie 

 deposits of the plains. Like these they are associated with lignite." There seems little 

 reason to doubt that these plants belong to the same volcanic Tertiary of more southern 

 localities, from which a very much larger representation has been secured at various times, 

 since identical species occur in both and the metamorphosed character of the matrix shows a 

 similar influence. 



BuRRARD Inlet. 



The only other Tertiary deposit that claiins consideration at this time is that at Burrard 

 inlet. In 1895 (20, 137-161) Sir William Dawson described a small collection from that 

 place and found : —

4. Vancouver ensis, Dn. 



5. Cyperites paucinervis, Heer.
