The examination of the surface soil for soluble silica and soluble matter, without ignition, 

 gave 20" 1207 of soluble matter, and soluble silica 0' 1852. About double the quantity is 

 obtained when the soil is not raised to a red heat : this we have found to be a constant 

 result. These soils lie upon the upper part of the Marcellus slate ; and upon the surface 

 there are a good many boulders or fragments of rock derived from the Chemung group, 

 and also some large boulders of blue limestone scattered over the farm. 



The following is an analysis of soil from another piece of land of the same farm, which 

 was cleared in 1816, and has been cropped most of the time since. Wheat has been 

 grown on the land for five years in succession : average crop, thirty bushels per acre. It 

 is now down (1846) to grass. The crops have never been poor.
