In addition to the mixed grasses growing upon the 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 by a yellowish stiffish clay, known as the Albany day. This soil, or 

 some combination of it with more s[\nd or clay, is the predominant soil of the towns in tiie 

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

 rably the manures when properly mixed with it. 



III. RED-TOP (Agrostis vulgaris). 

 Selected from dried hay.

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

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

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