 AViihihis are mimeroiis leaves of l^n/inhix Anlini, Ileer, and a few of P. hilior ; and also 

 speeies of C(ir/iiiiiig. IVn/iniiia, Nelnmbiinn, Siijiiiitliis, Mi/riai, lic/iilii. l^n/iiinis, Vdiriniinii, 

 Tiuiuliuni, ^ci/iwia and Glj/pliislnibua. and a franment of Thujii, not distiniiuishahlo from 

 T. occitleiitiilh. The species are dilferent from those found at Qnesnel. hi;l like them 

 apparently of Middle Tertiary age. 



III. — Reserve, North Tliomjmin^ : — 



The leaves from this place, in a matrix of grey arenaceous shale, are almost exclusively 

 poplars, referable to PojiiiIhs Aniicn, P. Geneliix, Newberry, and anothiM- species. With 

 these is a species of Rliiii<. allied to 7?. roainfofiu of Lesquerenx. 



When the plants from these localities shall have been fully collected and studied, il 

 will be time to otler opinions as to the precise horizons of the Tertiary which they reprc^ 

 sent. "With so small collections from only a few localities, the local dilierences are likely, 

 to some extent, to mask those depending on age. There can lie 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 Lii;iiite. and when this 

 shall be worked we may expect that larger collections will be available.
