for farm animals, and the relative values of such materials are discussed and 

 a talile given showing the equivalent amounts of n number of varieties. 



Experiments on the nutritive value of the nonproteid nitrogenous con- 

 stituents of hay, M. Mullee {Jour. LaiKhr., 5) {1901), Wo. 1-2, pp. 123-1^1). — 

 In continuation of earlier work (E. S. K.. 17. p. 684), the amid products obtained 

 from hay by exti'action with water and purification with alcohol were studied 

 in comparison with blood albumin in experiments with dogs. Judging by the 

 gains ii: nitrogen ;ind other recorded data, there was little difference in the two 

 rations, and the aiithor concludes that such nonproteid nitrogenous constituents 

 of hay may be used for tissue building in the body and so may replace protein. 



Additional experiments on the nutritive value of amids, M. MurxER 

 {FUhJiiig's Landw. Zt'g., 56 {1907), Wo. 7, pp. 219-239). — In a series of experi- 

 ments subsequent to those reported above, the nitrogen gains on the amids 

 occurring in hay were about twice as large as on free asparagin and about the 

 same as on blood albumin. When such factors are taken into account, the 

 author believes that amids can not be considered as having no nutritive value 

 and that they must be grouped with protein rather than with the carbohydrates, 

 as has been proposed. 



The use of town refuse in animal feeding, Herter . (Z>e//^. Lcundic. Presse, 

 34 {1907), Nos. 25, pp. 207, 208; 26, pp] 2U, 215; 27, pp. 222, 223; 28, pp. 232, 

 233; 29, pp. 21,1, 21,2; 30. pp. 249-251; 31, p. 261).— \ summary and discussion 

 of data regarding the value of food refuse and of municipal sewage-farm grass, 

 and related questions. 



Dried beet pulp molasses and denatured sugar in the feeding stuff of 

 farm animals, Bouchox {Siicr. IndUj. et Colon.. 69 {1907). Xo. IS, pp. .',9 ',-501, 

 fiy. 1). — A summary and discussion of data on the use of sugai'-beet products in 

 the feeding of farm animals, with a description of the apparatus for drying 

 beet pulp. 



Molasses feeds, A. Schlicht {Ilhis. Landio. Ztg., 27 {1907), No. 24, pp. 

 218-220). — A summary of data regarding the composition and food value of 

 molasses feeds. The author insists that the manufacturers should give definite 

 data regarding the composition and quality of their products. 



Materials employed to denature sugar for use in feeding farm animals 

 {Bettcravc. 17 {1907), Xo. 422, p. iiJ).— Salt, oil cakes, meat meal, fish meal, 

 and fish guano are among the products recommended for this purpose. 



Maize as a fodder and silage crop, E. J. Russell {Jour. Bd. Agr. [London], 

 14 {1907), \o. 1, pp. 14-22). — In a general summary and discussion of maize 

 with reference to the needs of English cattle raisers, the author points out that 

 large crops of this cereflJ can be grown in a number of districts in England. 



In general the composition of maize somewhat resembles that of grass ; " it 

 depends on the season and is least satisfactory in cold, wet seasons when the 

 croi) is small, and most satisfactory in hot, dry ones when the crop is large. 

 All classes of stock take to maize, and it is well worth a trial where succulent 

 fodder is wanted during September. 



" Maize can be converted into silage, which is quite a useful food, though 

 inferior to roots and mangolds. In the process of manufacture the loss of 

 dry matter was found to vary between 30 and 40 per cent, which loss falls mainly 

 on the nitrogen-free extract and least on the fiber. Except when mangolds are 

 unusually costly, it hardly appears worth while growing maize for the pro- 

 duction of silage." 



Analysis of ensilage from Biggenden State Farm, ,1. C. Brunnich {Queens- 

 hind Agr. Jour., 18 {1907), Xo. 4, p. 199). — The samples of corn and of sorghum 

 silage analyzed were 8 months old. The degree of acidity which was found
