duced to a similar arrangement with the rocks of England 
in the late work of Messrs. Conybeare and Phillips. The 
upper rock is the horizontal limestone containing hornstone, 
madrepores, branched corals, and numerous shells, partic- 
ularly univalves. This we venture to suggest as belong- 
ing to the great Oolite including the coral rag &c. Next 
beneath it is a series of beds of clay and marl of various 
colours, red, blue, &c. (perhaps the lias.) Lower down 
isared friable sandstone containing the salt and gypsum 
and nodular sulphate of barytes. Very fine sections of these 
may be seen at Rochester and Lewiston, particularly the 
latter, where the high banks exhibit a perfect display of all 
the strata from the limestone down to the sandstone. 
you cross the country ina line from Seneca Lake to the 
Catskill Mountains—you find after leaving the limestone a 
black horizontal argillaceous slate full of small bibalves.— 
This slate forms the shores of Cayuga and Seneca Lakes. 
Then advancing East to the head streams of the Susque- 
hannah, you find a brown and yellow slate closely resemb- 
ling the former.—As you go East, it turns red; till you 
finally reach the sandstones of the Catskill Mountains. 
East of that the country is evidently transition.—We have 
considered the slates between the two small lakes and the 
Catskill Mountains as belonging to the coal strata; east 0 
which we find, among other rocks, limestone in inclined 
strata, abounding in shells and hornstone, (perhaps the 
Mountain Limestone.) Our principal object in these re- 
marks is to fix the exact locality of the salt formation be- 
tween the coal strata and the horizontal limestone, and to 
ascertain the position of the latter rock in the European 
order. We offer these remarks only as suggestions, and 
we should be happy if they might aid any one in arriving 
at more definite conclusions.
