 starchy feeds, meat scraps, meat and bone meal, fish, bone, poultry mash and meal, 

 chick and scratching grains, and clover meal. 



Most of the different classes of feeds are discussed. In general they were of satis- 

 factory quality. A sample of wheat feed with admixtures was found which contained 

 a large quantity of ground corncobs, when the label indicated that it contained corn 

 and cob meal. Another sample was found to consist largely of ground wheat screen- 

 ings, with relatively small amounts of corncobs, oat clippings, wheat bran, and mid- 

 dlings. A tendency to add to mixed feeds inferior shrunken wheat grains, resulting 

 from the ravages of rust, was noted, and consumers are cautioned to be on their 

 guard against such deceptions. 



In the case of molasses feeds, the author notes that they are bulky and generally 

 intended to constitute the entire grain ration. " Such feeds should be dry, otherwise 

 they will mold and deteriorate rapidly. Moist, sticky feeds are also unpleasant to 

 handle." The digestibility of concentrated feed, the cost of digestible protein, and 

 related questions are discussed and suitable grain mixtures for feeding are suggested. 

 Data are also given regarding the market value of concentrated feeds. 



Digestibility of feeding stuffs by farm animals, together with a brief dis- 

 cussion of the digestive organs and digestibility, M. Mcller (Fuhling's Landw. 

 Ztg., 53 {1904), Nos. 2, pp. 66-71; 3, pp. 85-90; 4, PP- 134-144; 5, pp. 179-185).— The 

 author has summarized and discussed available data on the subject. 



The comparative value of organic phosphorus bodies in nutrition, A. 

 Desgrez and A. Zaky (Compt. Bend. Soc. Biol. [Paris], 57 (1904), No. 31, pp. 

 392-395). — Using lecithin, protylin, and nucleic acid, experiments were made with 

 guinea pigs. Rapid gains in weight were noted when the organic comhinations of 

 phosphoric acid were taken. In the longest test, the authors call attention to the 

 fact that the influence of lecithin and nucleic acid was less sustained than that of 

 nuclein and protylin. 



Water as a nutrient, E. Maurel (Compt. Bend. Soc. Biol. [Paris], 57 (1904), 

 No. 28, pp. 256-258). — Experiments which were made with guinea pigs led the 

 author to conclude that a quantity of water which corresponds to the normal amount 

 in the maintenance ration does not cause a permanent increase in body weight, and 

 that consequently water has no value as a nutrient. 



White mice fed clover hay with fatal results, P. Gordan (Landw. Vers. Stat., 

 60 (1904), No. 1-2, pp. 91-102).— With a view to determining the cause of the bad 

 results which are sometimes noted when clover hay is fed, experiments with white 

 mice were undertaken. The intensive feeding of this material caused intestinal 

 inflammation and death, but, as the author points out, it does not follow from this 

 that clover should be generally considered as an unsatisfactory feeding stuff. 



The conclusion was drawn that generally it is not the presence of injurious con- 

 stituents, as bacteria or their metabolic products, which gives horses the colic when 

 clover hay is eaten. The fact is rather that this material, even if clean and sweet, is 

 not well tolerated by animals with a sensitive digestive apparatus unsuited to its 

 assimilation. Whether the bad results are dependent upon chemical decomposi- 

 tion of the clover hay in the intestine or to a mechanical effect is still an open ques- 

 tion, but the latter supposition seems the more plausible in the light of the available 

 experimental data. 



Actual cost of beef making, J. H. Roe (Breeder's Gaz., 46 (1904), No. 18, pp. 

 799, 800). — Data are presented based on the author's personal experience. 



Lamb feeding experiments of 1903-4, B. C. Buffum ( Wyoming Sla. Bpt. 1904, 

 pp. 30-38, pis. 3). — After a preliminary period on alfalfa without and with oats, the
