368 EXPERIMENT STATION EECORD. [Vol. 38 



methods discussed involve a return to tliose of tlie earliest German investi- 

 gators, wliere one feed is fed against another in a standard ration. The results 

 are expressed comparatively with one food used as a basis, as barley. The 

 tables of comparative values are estimated for different classes of animals. 



In the actual practice of feeding, further economies are foand in basing the 

 ration upon the gains sought, the vpork to be done, and the milk yield. In the 

 last case, for example, the ration is based upon the weight of the cow, and the 

 daily yield of milk. 



Feeding stuffs, F. J. Lloyd {Jour. Brit. Dairy Farmers' Assoc, 31 (1917), 

 pp. 119-129). — A paper presented by the chemist of the association containing 

 a r6sum6 of the value of feeding stuffs and directions for purchasing them to 

 the best advantage for individual needs. 



The composition of some South Indian foodstuffs and fodders, W. H. Har- 

 bison (Madras Agr. Dept. Yearbook, 1917, pp. 62-72). — A long list of fodders 

 analyzed is given. Among those mentioned are Eleusine coracana, Pennlsetum 

 typhoideum, Ciccr arietinum, Phaseolus mungo radiatus, P. aconitifoUus, Ca- 

 janus indicus, Dolichos biflorus, D. lablab, Sesamum indicum, Guinea grass, 

 spineless cactus, and Teff grass hay. 



The feeding value of the hay of seed vetch and cleaned vetch, J. Gbqh 

 and I. D. Gotz (Kisirlet. Kozlem., 19 (1916), No. 2, pp. 387-390).— In a trial 

 with two sheep, it was found that with a water content at 12 per cent the seed 

 vetch hay contained 8.1 per cent digestible protein and 36.8 per cent nitrogen- 

 free extract; the cleaned vetch hay, 101.1 protein and-37.8 nitrogen-free extract. 



Observations on silage, A. W. Oldekshaw (Jour. Bd. Agr. [London'\, 23 

 (1917), No. 11, pp. 1063-1072, pi. 1). — A discussion of methods of ensiling prac- 

 ticed in East Anglia, with a description of the more modern types of silos that 

 should be used. 



The leaves and crowns of sugar beets as feed, L. Malpeaux (Vie Agr. et 

 Rurale, 6 (1916), No. 48, pp. 386-390). — A compilation and discussion of results 

 of feeding beet tops fresh, dried, and ensiled. 



Sugar beet leaves as cattle feed, E. Saillakd (Vie Agr. et Rurale, 7 (1917), 

 No. 38, pp. 207, 208, fig. 1 ) . — A description of the practice of ensiling sugar beet 

 residues in France, together with analyses of ensiled pulp and leaves. 



Commercial feeding stuffs, A. J. Patten, E. F. Bergee, E. A. De Windt, and 

 A. E. Smoll (Michigan Sta. Bui. 279 (1917), pp. 3-66, figs. 8).— This contains 

 the text of the new feeding stuffs law becoming operative April 1, 1918, and 

 analyses of various brands of commercial feeding stuffs, including cotton- 

 seed meal and feed, linseed meal, distillers' dried grains, brewers' dried grains, 

 corn gluten feeds, hominy feeds, corn meal, tankage, granulated bone, meat 

 scrap, alfalfa meal, wheat bran and middlings, pea bran, barley bran, and 

 proprietary feeds. 



A smaller number of samples were analyzed this year than last, due probably 

 to the scarcity of feeding stuffs on the market. Of the 837 samples analyzed 

 16.2 per cent were below guaranty in protein or fat, this number of deficiencies 

 being 4 per cent below that found last year, while 15.4 per cent had an excess 

 of crude fiber over the guaranty. A large amount of weed seed was found in 

 scratch feeds for poultry, some of which were very objectionable. One sample 

 containing seeds of night-shade was fed to hens, all of which were affected, 

 two dying. 



Attention is called to the use in feeding stuffs of by-products from palm oil 

 manufacture, copra oil meal, and cacao shells. 



Analysis of feeding stuffs, B. E. Cubby and T. O. Smith (New Hampshire 

 Sta. Bui. 184 (-1917), pp. 16). — During the year 302 samples of feeds were col-
