many years for maize, having been distinguished for its steady and abundant yield of this 
exhausting crop. The element which seems to have been removed by cultivation, is 
magnesia. 
Soil near Hoosic corners. 
This soil was not fused with soda.

The succeeding analysis was made of a soil which has never been manured, and has 
been in grass thirty years : it has, however, received the wash of a higher piece of ground. 
It is upon the same formation as the preceding. The land is owned and cultivated by 
Mr. L. C. Ball, of Iloosic falls, three miles north from Hoosic corners.

1. Position of the soil. b. Soil in which there is much disintegrating slate. 2. Slate beneath, with a southeasterly 
dip, which is the uniform dip of all the underlying rocks through this range of country : it varies in amount, 
passing through a range from 35° to 65°. The slates, in consequence of their close packing, and which has been 
increased by compression, never permit the water to percolate through them.
