QUESNEL RiVEK. 



The Quesnel river enters the Fraser at Quesnel passing through about eight or 

 ten miles of a tormation usually regarded as Miocene. Of the formation at this point, 

 Dr. Dawson (10,257) observes that at a place one-half mile below Quesnel, on the Fraser, the 

 lignite has entirely disappeared by combustion, and the clays and sands have been baked and 

 caused to assume various shades of yellow and red. Rocks resembling ordinary brick and 

 biscuit porcelain are most abundant, but some layers are semi-vitrified and others containing 

 much iron have melted to a vesicular slag. 



Our knowledge of the flora of tbis formation is based upon two collections made hy 

 Dr. G. M. Dawson in 1871 and 1875, and determined by Sir "William Dawson. In his report 

 upon the first collection from the mouth of the Quesnel (18, 59) he reports : — 



L Acer'sTp. 



2. Platanus sp. Wood and leaves. 



3. Populus sp. Wood and leaves. 



4. Pterospermites sp. 

 ^. Quercus sp. 



In 1875 he extended this list and gave a more specific indication of the types found. 

 (16, 259-260). The specimens were all small and imperfect, but they admitted of a recogni- 

 tion of the following species : — 



1. Acer sp. Probably comparable with A. grossedentatum of the European Tertiary. 



2. Betula sp. Probably B. prisca. 



3. Garya sp. Nut.
