[Assembly 
of Connecticut, between Salisbury and Sharon, and about six miles N. 
E. of Amenia. This bed has been described by Prof. Shepard.* It 
furnishes about 2,000 tons of ore per annum. The limestone forms its 
west, and the micaceous slate its east boundary. 
The Salisbury beds are five or six miles farther north. They are ex- 
tensively wrought J (about 5,000 tons per annum.) They also have 
been described by Prof. Shepard.f 
Copake ore bed, two miles N. E. of Copake Flats, is worked, but not 
extensively. It yields about 1,500 tons per annum. 
The limestone crops out a little west of the bed, and mica slate also 
not far on the east. The ore is probably abundant at a greater depth, 
but the mine may become a wet one if it be dug much deeper. An 
ore bed has also been opened two or three miles south of the above, 
and a mile or two north of Boston Corners, in Massachusetts. 
The localities which have been described, are openings made in a few 
places, in extensive deposits of ore, and small quantities comparatively 
have been taken from them, while they are capable of yielding millions 
of tons to the enterprise of our citizens. The beds are undoubtedly 
continuous for great distances, and are a part of the great chain of iron 
deposits which extend from Canada to the Carolinas. 
Although on the east side of the Hudson River, we have not moun- 
tains of iron ore, in the first district, we have beds which are inexhaus- 
tible, and so widely distributed, as to afford facilities of water power, 
fuel, &c. for a greater number of furnaces, than could be accommodated 
around one unwieldy deposit. 
About 2,000 specimens have been collected for the State, during the 
past season, to illustrate the Geology of Queens, Kings, Richmond, 
Dutchess and Columbia counties. These, together with those of Suf- 
folk county, are arranged in cases in the Geological Rooms of the first 
and second districts, above the State Library, in the Capitol. 
There are eight suites, labelled and arranged, one of which is dis- 
played in glass cases. The seven duplicate suites are arranged in se- 
ven layers of drawers, and are similar to that exposed to view.
