SPECIAL STUDIES OF FEEDING STUFFS. 



A miinlxM' of Aniorican invcstic^ators havo puhlislicd special studies 

 doaliii<i: with ditl'oront crops, ^frains, etc., which should l>c nicutioiicd 

 in :i suuuuarv of the work on the jreupral sul)jcct of feeding stuli's pub- 

 lished duriniif the period covered by this coinj)ila(ion. 



At the ()re<>()n Station, A, L. Knisely'* studied the composition of 

 the diti'erent parts of the lupine plant. 



J. Stewart,'' at the Utah Station, studied the composition of the dif- 

 ferent parts of the Golden Vine tield pea, and H. K. Miller,' of the 

 Florida Station, studied the velvet bean. 



C. D. Smith '^ carried on an extended investit^-ation at the Michig-an 

 Station of the shrinkage of oats, corn fodder and other corn products, 

 and clover hav during storage. 



At the Alabama Station, J. F. Duggar' studied the composition of 

 ditierent parts of the cowpea plant. 



C. H. Jones and B. O. White,-^' at the Vermont Station, made special 

 studies of the composition of the nitrogen-free extract matter of pota- 

 toes and artichokes. 



Chemical studies of the changes in crops during the process of 

 ensiling were made at the Oregon Station by J. Withycombe.fi' 



Work which is regarded as preliminary was carried on by J. With}^- 

 combe and A. L. Knisely, ''on treating corn fodders in silos with 

 steam. The chemical composition of such silage was studied, as well 

 as that of silage treated w^ith salt with and without the addition of 

 water, and silage which had received no special treatment. 



F. S. Shiver* has made an extended investigation of the composi- 

 tion of the Sea-island cotton plant and its parts. Numerous analyses 

 were made of the seed, kernels, hulls, linters, lint, and meal of two 

 varieties; the constants of Sea-island cotton-seed oil were determined, 

 •and the form in which phosphoric acid exists in the meal was studied. 

 The investigations have also included determinations by the phenyl- 

 hydrazin and phloroglucin methods of the pentosans in different parts 

 of the plants. Pentosans were found to be widely distributed in the 

 Sea-island cotton plant and its products, varying in amount from 1.53 

 per cent in lint to 21.88 per cent in the hulls. 



J. T. Willard, R. W. Clothier, F. C. Weber, et al.,^' have reported 

 numerous anal3^ses of corn, made during a period of four years. The 

 object of the work has been mainly to improve the protein content of 

 corn, the results indicating that the most practical means for this pur-
