Proceedings of the American Society of Animal Nutrition (Amer. Soc. 

 Anim. Nutrition Proc. J909, pp. 36). — Papers are here printed in full wliicli have 

 been previously noted (E. S. R., 22, p. 96). 



Some observations on the fermentation of silage, W. M. Esten {Science, 

 n. set:, 31 (IDIO), No. 7.97, pp. 5.'/7, 5-'f8). — This is an abstract of a paper read 

 before the Society of American Bacteriologists, December, 1!)09. 



Lactic-acid bacteria grew profusely in corn juice until about 0.35 to 0.4.5 per 

 cent of lactic acid was formed, when they ceased to grow. The yeasts wex*e 

 tolerant to much larger amounts of acid and continued to grow until practically 

 all the sugar was used up. In fresh silage large numbers of yeasts and acid 

 bacteria were found. The biochemical changes were nearly all completed during 

 the first 12 days. The maximum growth of the acid bacteria was on the fourth 

 day and the maximum growth of yeast on the twelfth. The highest tempera- 

 ture, .29° C, was noted the first 36 hours. Samples were taken from a hole in 

 the silo 5 ft. from the bottom and from 1 to 2 ft. from the edge. 



Investigations on the digestibility of palm-nut-cake meal and palm-nut 

 meal from which the fat had been removed, E. Weinuikk ( IjUndw. Vcrx. Stat., 

 "12 (1910), No. 1-2, pp. 1'i3-1'j0). — In digestion experiments with wethers, on a 

 basal ration of hay, the average digestion coefficients of 2 kinds of palm-nut 

 meal rich in fat were dry matter 76.4, protein 76.5, nitrogen-free extract 88.8, 

 fat 78.6, and fiber 39.4 per cent. The coefficients for palm-nut cake from which 

 the fat had been removed were dry matter 79.0, protein 74.2, nitrogen-free ex- 

 tract 92.6, and fiber 55.2 per cent. 



Investigations on the digestibility of seed beet straw and sugar beet seed 

 residue, P. Eisenkolbe (Landw. Vers. Stat., 12 {1910), No. 1-2, pp. 151-157). — 

 Digestion experiments were made with wethers in which hay, cotton-seed meal, 

 and sugar formed the basal ration. The digestion coefficients of seed beet 

 straw were dry matter 33.9, protein 40.5, fat 36.5, nitrogen-free extract 41, and 

 fiber 24.9 per cent. The coefficients of beet seed residue were dry matter 37.1, 

 protein 57.2, fat 63. nitrogen-free extract 45, and fiber 17 per cent. 



Analyses of feeding stuffs grown on marshy soils, H. von Feilitzen {Jour. 

 Landir., 57 (1909), No. 3, pp. 231-236). — Analyses are reported of rye, barley, 

 oats, hay. field pea {Pisiim urrense), kale (Brassica oleracca acephahi), vetch 

 {Vicia narhonensis and V. villosa), Jerusalem artichoke, and Sphagnum cuspi- 

 datum. 



Licensed commercial feeding stuffs, 1909, F. W. Woll {Wisconsin Sta. Bill. 

 19Jf, pp. 3-9.'i). — Analyses of 766 samples of feeding stuffs are reported, in- 

 cluding wheat, rye, barley, and buckwheat products, linseed and cotton-seed 

 meals, gluten feed, alfalfa meal, blood meal, hominy, corn chop, corn-and-cob 

 meal, malt sprouts, distillers' grains, tankage, beef scraps, meat meal, and 

 mixed feeds. There is a discussion of results and of the amendments to the 

 state feeding stuffs law. 



Results of the examination of stock feeds, B. L. Purcell {Ann. Rpt. Dairy 

 and Food Comr. Va., 1 (1908-9), pp. 112-lJi5). — Analyses are reported of wheat, 

 rye, and corn products, red dog flour, cotton-seed meal, oats, dried beet pulp, 

 beef scraps, molasses feeds, and other mixed feeds. 



Notice of judgment (U. S. Dept. Ayr., Notice of Judgment 256, pp. 3). — This 

 has \() do witli the adulteration and misbranding of a stock food. 



Winter feeding of farm stock, H. G. Mxjndy (Rhodesian Agr. Jour., 7 (1910), 

 No. 3, pp. 1093-1101, pis. 3). — This article describes methods of feetling dairy 

 cows under the conditions which exist in Rhodesia. 



The crops recommended for conversion into silage or dry fodder for winter 

 feeding are maize, sweet sorghum, teosinte, sugar cane, i)earl millet, Boer 

 manna (Sctaria italica), Japanese millet, teff grass (Eragrostis ahyssinica),
