GEOLOGY OF THE THIRD DISTRICT. 
J he hills around Cazenovia village are chiefly composed of the coarse shale, similar as to 
kind and fossils with those of Lewis’ quarry, etc. They are well exposed in crossing the hill 
to the west, or on the hill-side to the southeast, and are the Cazenovia shales of Mr. Conrad. 
In mineral character, they constitute, as has before been said, the larger part of the whole 
group; they are of the kind which, when long exposed, become of a brownish color ; they 
decompose or .wear away very slowly, and are the common building material of their range. 
Chenango county. Though but little is exposed of the group in this county, there are four 
points of interest. The first is Ladd’s quarry on the canal, near Madison county line, and is 
the continuation of the range of West Hamilton; the quarry is rich in many of the fossils of 
the group, being in all respects like the quarry back of the Baptist College near the top of 
the hill. Considerable stone is here taken out, being convenient for transportation. The 
specimen in the Collection, showing the impression and part of a bone of a fish over two 
inches in length, and more than an inch in width, is from this quarry. 
I he next point is the falls and banks of Handsome creek, north of Sherburne. The water 
falls for sixty or more feet, and the sides of the creek expose about one hundred feet of the 
finer kind of shale. Many fossils, which are common to the mass below the encrinal lime¬ 
stone at Ludlowville, and the mass generally of the group, may be obtained at the creek.
