74 A List of Minerals and Organic Remains. 
It has been penetrated for sixteen feet, and yields about a 
peck of salt for every seventy gallons of water; but it is 
supposed to be weakened at present by the brackish, stagnant 
water, which surrounds the spring in patches for one quarter 
of a mile square. There are several salt springs in the 
township of Percy county, Northumberland, at which much 
salt was made during the late war between Great Britain 
and the United States. There are several also in the town- 
shipof Whitby, East Riding of the county of York, issuing 
from clay and increasing in strength with the depth from 
which itis raised. Others are at Chinkecusheé on the river 
Credit, in the township of Toronto, another in the seventh 
concession of Esquising, and many about Burlington Bay 
and St. Catharines s~-some of which are worked. | 
Indians report that on the south shore of Muddy Lake, 
a part of Lake Huron, there are brackish marshes. 
Sulphur —in yellow pulverulent efflorescences, and in tufts 
of minute capillary crystals, coats the moist calcareous shale 
at the foot of the horse-shoe fall of Niagara, and within the 
curtain of falling water. 
Bitumen.—Mr. Bird, late Astronomer to the boundary 
commission under the 6th and 7th articles of the Treaty of 
Ghent, showed me masses of fetid pale brown limestone 
from the south shore of Lake Erie, which when held be- 
fore a fire for a few moments shine and become viscous 
from a thin coating of bitumen which then becomes appa- 
rent by liquefaction. Major Delafield has limestone from 
the north west of Lake Huron holding this substance in 
still greater quantities. 
Coal.—Minute seams of coal, jet black, shining, very 
light and brittle, have been found in the cliffs of the Grand 
Battery of Quebec, and in Cape Diamond ;—in both ca- 
ses, in black transition limestone. 
Scaly Graphite.——In large bowlders of translucent quartz, 
on the Ottawa, in the township of Hawksbury. In bowl- 
ders of white feldspar at the fort of Cape Tourment ; —in 
both instances disseminated in small crusts or scales —The 
granular form of this mineral has been brought in consid- 
erable quantities from a creek 3miles east of Kingston, U. C. 
Variegaied Copper Pyrites—occurs in abundance among 
the beds of magnetic iron ore.of Crow Lake, in the town- 
ship of Marmora. It has 2 purple tarnish.
