Extracts from the Minute Book of the Geological Society . 599 
The notes concerning the rocks found on the banks of the 
Nelson river are extracted from the journal of Mr. W. Auld, an 
officer of the Hudson’s Bay Company, appointed to survey the 
lower part of that river from York fort to Split lake. A few 
specimens from the same river below Split lake were obtained 
from Mr. Kerney, a gentleman who after visiting an Indian village 
on the Missouri, about the latitude 47° and longitude 101°, 
descended the river Nelson from lake Winipic to York fort. 
A description of the few specimens which he collected on the river 
Nelson will be appended to the notes of Mr. Auld. 
The observations on the route from York fort to Winipic, and 
thence to the Red river, were made by Mr. Abel Edwards, Surgeon 
to the Settlement on the Red river ; and it is by this gentleman, 
and in the course of the route which he pursued, that the specimens 
transmitted to the Society were chiefly collected. The specimens 
from No. 14 to No. 27, both inclusive, were collected by 
Mr. Holdsworth, surgeon at York fort, and by him together with 
the observations that accompany them, transmitted through Mr. 
Edwards to Lord Selkirk. 
Notes upon Nelson River , near York Fort , Hudson s Bay , extracted 
from the journal of a survey made by Mr . W. Auld , July, 1812. 
The high banks begin near the mouth of the Nelson river, 
about seven miles below Flamborough Head, being at the head 
about 100 feet high. They are of a light clay-colour, composed 
of mud and sand with a few small stones, and are of a very firm 
consistence, presenting every where a steep ascent, except where 
water has undermined them. Where this has happened, portions 
of the cliff have slipped down ; and these are soon swept away 
by the strong current of the river. Opposite to the Seal Islands,
