SECTION IV., 1895. [137] Trans. R. 8. C. 
VI.—On Collections of Tertiary Plants from the Vicinity of the. City of 
Vancouver, B.C. 
By Sir WiLLrAm Dawson, F.RB.S., etc. 
(Rerd May 15, 1895.) 
In the southern part of the province of British Columbia, in the 
district extending from Burrard’s Inlet to the United States boundary, 
and which has long been coloured on the maps of the Geological Survey 
as of Tertiary age, while the sections accompanying these maps show its 
rocks as overlying the Cretaceous coal-measures of the Nanaimo group, 
fossil plants and beds of lignite have for some time been known to exist, 
but the former have not been specially studied. The beds have, however, 
been regarded as probably continuous with the lignite-bearing formation 
of the eastern part of Washington Territory, recently designated by the 
geologists of the United States Survey as the Puget group. 
In the Report of the Geological Survey of Canada for 1876-7," notices 
of this formation appear by Dr. G. M. Dawson and by the late Mr. 
Richardson. Mr. Bowman was subsequently engaged in exploring it for 
coal,’ and small collections of the fossil plants have been made by several 
of the officers of the Survey, and more recently a larger collection has 
been made by Mr. G. F. Monckton, of Vancouver. 
The geological relations of the beds, as ascertained in Canada, are 
referred to by Dr. G. M. Dawson, in a paper published in the “ American 
Journal of Science” for 1890, as follows : 
“While referring to the Puget group, it may be added that a con- 
siderable tract of low land about the mouth of the Fraser River, and 
extending northward to Burrard Inlet, is underlain by rocks which, 
though as yet only partially examined, appear, with little doubt, to cor- 
respond to that group, with which they are geographically connected, 
and, so far as known, lithologically identical. My. A. Bowman has 
ascertained that these strata are at least 3,000 feet in thickness, and, like 
those of the typical area of the Puget group, they hold carbonaceous 
matter and more or less lignite coal at many different horizons.” 
In the same paper he remarks on the possibility that some of the 
unfossiliferous beds overlying the Cretaceous coal-measures of the Na- 
naimo group at Comox and elsewhere in Vancouver Island, may repre- 
sent this same Puget group, or in part the underlying Tejon group of 
California.
