Rocks and Minerals of U. Canada. 63 
milton’s Cove on its north shore is eavernous to a very great 
degree, the limestone quarter of Uedar Island is the same, 
and there are some tokens of vast caverns under Point Henry, 
as a stream, which is of some volume ia spring, loses itself 
suddenly there in a chasm. 
Orthoceratites.and other organies are found here, the bival- 
ves are, however, not very common, and the orthoceratites 
seem to belong to large slabs which have been transported, ra- 
ther than toany rock in stlt, 
Chain coral (tulsipora catenulata)madrepores and the honey~- 
comb fossil (fayoisite) are found on the islands in the vicini- 
ty, but not very perfect; and amongst other things a small slab 
was picked up Jately, on which is the perfect appearance of 
alarge plant in alfo relievo, with some leaves beside it. 
2. About fifteen miles from Kingston, iu the township of 
Loughborough, galena aud broad plates of mica, as well as 
ecarburet of iron, exist as [am informed. Pipe clay very 
pare is found near the forty mile creek in the Niagara district, 
and there is also a lange bed of sulphur, Iead is found at Mud 
Creek, iv the county, or rather township joining Pelham, and 
fine granular gypsum at the Grand River, in such quantities 
as to be common on all the farms in the Niagara district. 
Selenite (crystallized gypsum ) is found at Fort George, and 
at Beckett’s Mills. Atthe Short Hills there is a singular 
declivity in the woods, which bears every appearance of hav- 
ing been an ancient waterfall; some water still oozes out of che 
rock at its base,and here are strewed masses of agatized wood 
and hornstone, apparently formed by the petrifying qualities of 
the ancient stream, 
There is an extensive bed of iron pyrites in the woods at 
the Short Hills, and thereabouts occur crater like hollows, 
which may probably have been formed by the combustion of 
that mineral; the lips of the cups, however, ave not high, and 
it is equally probable that these hollows may have been cave 
ed by the sinking of the sand.
