 characteristics are similar." 



Concerning the composition and digestibility of hay from sewage meadows, 

 J, YoLHARi) {Landir. Vers. Stal., 68 (1908), .\o. /-2, pi). 11-18). — Using sheep 

 as subjects, the digestibility of early-cut and late-cut hay from sewage meadows 

 was studied. The author calculated that the early-cut hay had a starch value 

 of 30.5 and the late-cut hay of 29.1. 



The composition of hay from sewage meadows and the question of feed- 

 ing calcium phosphate, 1*. Ehrenberg (Landw. Vers. Stat., 68 (1!)08), No. 1-2. 

 pp. 19-38). — The author reports results of a number of investigations which he 

 has carried on and summarizes the work of other investigators. Accordinj: 

 to his analyses, the sewage meadow hay under consideration regularly contained 

 more protein and albumin than ordinary meadow hay from a similar locality. 

 The sewage meadow hay was richer in phosphoric acid and contained on an 

 average less calcium. 



The desirability of feeding lime instead of calcium phosphate with sewage 

 meadow hay is discussed but, in the author's opinion, can not be definitely 

 decided on the basis of evidence now available. 



German potato flakes, J. E. Kehl (Daily Consular and Trade Rpts. [U. 8.1, 

 1908, No. 3122, pp. 5, 6). — The manufacture of flakes from the surplus potato 

 crop and the commercial importance of such products are considered, and 

 rations containing potato flakes are suggested suitable for calves, cows, pigs, 

 and horses. 



" Nsa-Sana " seeds from southern Nigeria (Bui. Imp. Inst., 5 (1907), No. 4, 

 pp. 369. 370). — Oil was expressed experimentally from Nsa-Sana seeds (Ricino- 

 dcndron nfricduum) and the specific gravity and other constants determined. 

 The oil is similar to t'ung oil (Chinese wood oil), which is of importance com- 

 mercially. It is stated that the cake remaining after the expression of the oil 

 would have a feeding value approximating that of decorticated cotton-seed cake, 

 but as there are indications of the presence of an alkaloid, it would be necessary 

 to study the material thoroughly before it could be recommended for such a 

 purpose. It could, however, be utilized as a fertilizer, since it is rich in nitrogen. 



Dried grape marc as a feed for farm animals, Semichon (Soc. Aliment. 

 Rationn. Befail, Compte Rendu 12. Cong.. 1907, pp. l.'/.'f-1.50). — A paper with 

 discussion on the feeding value of grape marc. 



Experiments on the composition and digestibility of some by-products 

 from ethereal oil manufacture, F. Honcamp and T. Katayama (Landiv. Vers. 

 Stat., 67 (1907), No. 1-2. pp. 105-128; Sachs. Landw. Ztschr., 55 (1907), No. 36, 

 pp. 953-955). — Studies of the composition and digestibility of the materials 

 remaining when oil is made from a.iowan (Carum ajowan), celery seed, and 

 coriander seed. The digestion experiments were made with sheep. In general, 

 only about 50 per cent of the protein was assimilated. 



Composition of Hawaiian feeding stuffs, Alice R. Thompson (Haivaii Sta. 

 Rpt. 1907, pp. 63-66). — Analyses are reported of sorghum, sorghum silage, com 

 cut for the silo, corn silage, millet roots, hilo grass, Rhodes grass, pili grass, 

 para grass, side oats grama, and other grasses, wheat hay, rice straw, alfalfa., 

 cowpea forage, cassava refuse from starch making, taro waste, Tacca pin- 

 natiflda, ti root, beets, algeroba beans, algeroba bean meal, Spanish needles., 

 pakana (Mclilotus offlcinalis). rape, and annual ilima (Sida sp.). 



Feeding stuff inspection, C. D. Woods and J. M. Bartlett (Maine Sta. Bui. 

 156, pp. 157-202). — Under the provisions of the State law upward of 500 sam- 

 ples of feeding stuffs were examined, including cotton-seed meal, cotton-seed 

 feed, linseed meal, gluten feed, distillers' grains, brewers' grains and malt 

 sprouts, miscellaneous reenforced feeds, molasses and sugar feeds, corn, barley
