In addition to the mixed grasses growing upon (he soil of this lot, I may add the Early 

 Shaw potato, beet, carrot, and tomato vines. I have under cultivation upon the same lot, 

 several varieties of indian corn which have been already analyzed, and more in a state 

 of preparation for this process. The soil is sandy to the depth of two or three inches, and 

 is then succeeded b}' a yellowish stiffish clay, known as the Albany day. This soil, or 

 some combination of it with more sand or clay, is the predominant soil of the towns in the 

 valley of the Hudson river. It is an excellent soil for many productions, retaining admi- 

 rabty the manures when properly mixed with it.

It appears from the foregoing analysis, that this is a valuable grass, containing less silica 

 than the mixed grasses consisting of timothy, speargrass, red-top, some clovers, etc. The 

 amount of magnesia is large, and the soda nearly twice as large as in the mixed grasses.
