many years for maize, having been distinguished for its steady and abundant yield of tins 

 exhausting crop. The elemenl which seems to have been removed by cultivation, is 



magnesia. 



Soil near Hoosic torners. 

 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 Hoosic 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.
