A single sample of No. 2 analyzed by the New York Station is in 

 harmony with the guaranty. It seems practically certain therefore 

 that the description of Sample No. 94 is erroneous. 



Microscopic examination shows nothing noteworthy. 



BUCKWHEAT AND ITS BY-PRODUCTS. 



Buckwheat is the source of a number of by-products of the widest 

 difterence in feeding value. The grain is composed of a thick, dark 

 brown hull, made up of four layers of different tissue; the grain 

 proper is covered by a thin branny coating, under which lies a 

 layer of aleurone cells, rich in protein like those of the common 

 cereals, and tiually, lying within this layer, is found the endosperm 

 from which the tlour is made. The milling products, properly classi 

 lied, are as follows: 



1. The flour, including the endosperm with as little as possible 

 of the other layers. 



2. The middlings, composed in part of the endosperm and aleurone, 

 layer, and containing a portion of the true seed coat. 



3. The bran, composed chiefly of the true seed coat, with small por- 

 tions of the aleurone layer and endosperm. 



4. The bulla 



5. Buckwheat feed composed of hulls and bran or middlings, often 

 with a portion of the hard outer layer of the hull removed. 



The general percentage composition of the several principal parts 

 of the grain, as separated by milling, is as follows: 



That is to say, there is very little difference between the bran 

 and middlings in practice. The hulls are woody and of low digesti- 

 bility; they possess little feeding value.
