ANALYSES OF BARLEY. 129 



I remarked, in the foregoing paragraph, that this sample of grain gave a result some- 

 what different from that of barley grown in Western New- York. It will be observed, also, 

 that the straw is different, having less lime, magnesia and chlorine. This straw differs 

 also from a sample received from Col. H. S. Randall, of Cortland county. 



III. BARLEY RECEIVED FROM Col. H. S. RANDALL. 



Raised in Cortland ville, Cortland county. Rock of the county, shales of the Ithaca group, greenish

 The lime and magnesia, in this sample of barley, exceed considerably that of Judge 

 Peters, which was grown upon the shales of the Onondaga-salt group, in which the 

 amount of lime exceeds that either of the Hudson-river district, or the higher range of soils 

 from the slates and shales of the Hamilton and Chemung groups in the southern tier of 

 counties. I have not been furnished, in either case, with the mode of culture, or the 

 manures which were used; facts which, perhaps, would throw some light upon the cause 

 of the differences in composition of the three samples of barley. 



IV. ANALYSIS FOR OBTAINING THE PROXIMATE ELEMENTS OF BARLEY. 



The method pursued was the mechanical one, by which, from its imperfections, it is 

 impossible probably to represent the true composition. This objection, however, bears 

 with greater force upon the separation of the starch and products representing the gluten. 

 Raised and furnished by Judge Peters, of Genesee county.
