598 Extracts from the Minute Book of the Geological Society . 
shafts at several miles distance have been sunk, though long since 
filled up, of which no history gives us any relation. 
Ross vein lies parallel to Mucrus vein, at the distance of one mile 
and a half, and in the same bed of limestone. East of Ross Island, 
at Mr. Richard Herbert’s, of Capirnaane, a trial has been made, and 
lead found (probably in Ross vein.) Lead or copper is also said to 
have been met with in a small island, lying midway between 
Capirnaane and Ross, but little is known respecting it. 
There is a house remaining at the new shaft, formerly used as an 
assaying furnace or office. 
Six years ago the new shaft remained open, and it may now be 
cleared at a small expense, being still dry. 
The late Mr. Herbert, who had very considerable knowledge of 
chemistry and metallurgy, expressed his opinion in the year 1756, 
that if copper gave £60 per ton, the ore of the new shaft would be 
worth working.

Notes concerning the Geology of part of North America, lying 
to the west of Hudson’s Bay, extracted from various papers pre- 
sented to the Society by Earl Selkirk. 
The following geological observations upon a part of the territory 
of the Hudson’s Bay Company were transmitted to the Geological 
Society, by their late member, the Right Hon. Earl Selkirk. His 
lordship having at the same time presented the Society with a 
collection of specimens from the rocks referred to in these 
observations, the descriptions of all the rocks, of which specimens 
have been received, have been corrected by an examination of the 
specimens themselves.
