Extracts from the Minute Book of the Geological Society . 603 
yards long, composed of many hundred blocks of limestone each 
weighing several tons, and four feet thick or upwards, resting upon 
stones of a smaller size. This shoal, never having been observed 
before, must have been formed during the deluge of ice in the spring. 
It is not impossible that the next spring will entirely remove it. 
Notes taken during the summer of 1812, on a journey fro?n York 
Fort Hudson s Bay , to hake Winipic and the Red River, by Mr. Abel 
Edwards , surgeon at the settlement on Red River ; together with a 
description of the specimens collected by Mr. Edwards and by Mr. 
Holds worth, surgeon at York Fort. 
Hayes's River. The current uniform, compared with that of 
most of the other rivers between York fort and Lake Winipic. 
The bed stony.* The shores on both sides bold and low alternately. 
The soil loose and argillaceous ; but in some places sandy. 
Steel River. At its entrance into Hayes’s river very narrow, but 
soon becoming wider. The colour of the water whitish, forming 
a striking contrast with the colour of the water of Hayes’s river. 
The current more uniform than that of Hayes’s river. The bed 
stony. The greatest depth of water nine feet. The shores similar 
in appearance to those of Hayes’s river, but the soil rather more 
sandy. 
Hill River. The current strong and interrupted. The bed 
stony. The shores resembling those of the two former rivers, 
except that where the banks are high, they are more sloped. At 
the first carrying place the descent of water is about eight feet 
perpendicular. The portage is over a bed of granite intersected by 
large veins of quartz running east and west. 
* From Mr. Auld’s observations, it seems probable that limestone forms the stony bed 
of this river
