 (1915). No. 33, pp. 291-293). — The Abderhalden dialysis method of determining 

 the gestation of animals is described. It is stated that its results are quite 

 accurate if sufficient care is taken in making tlie test. 



Production and improvement of animals, P. Diffloth (Zootechnic G6n- 

 ^ralc. — rroduction ct Amelioration du B6tail. Paris: J. B. Baillidre d Son,

Animal production in Argentina, J. A. Richelet {BoI. Min. Agr. [Bncnos 

 Aires], 19 {1915), No. 8-9, pp. 655-675). — An account of the development of the

Feeds and feeding manual, E. S. Savage {Madison, Wis.: The Henry-Morri' 

 son Co., 1915, pp. 96). — This manual is designed for the use of the student in 

 collecting data and in making a systematic study of feeds and rations. 



Grain millet as a feedstuff, J. Hansen et al. {Arb. Deut. Landw. Gesell., 

 No. 264 {1914), PP- 151). — A review of a number of experiments in feeding grain 

 millet to farm animals. 



It is concluded that this feed is especially good for fattening cattle, sheep, 

 and swine, comparing favorably with barley and corn. When fed to dairy 

 cows at the rate of 3 kg. per day per 1.000 kg. of live weight, the millet proved 

 to be a very desirable feed, but when fed in larger amounts it caused a depres- 

 sion in the milk yields and butter-fat content. 



Feeding potato foliage as hay and as silage, W. Voltz (ZtscJir. Landiv. 

 Kammer Braunschtceig, 84 {1915), No. 20, pp. 167, 168). — The composition of 

 potato foliage hay is given as dry matter 8.5.7, organic matter 72.7, protein 11.8, 

 fat 2.8, nitrogen-free extract 35.1, fiber 23, and ash 13 per cent. Both as hay 

 and as silage, potato foliage has proved a very desirable feed for all classes 

 of stock. 



Silos and silage, A. Stutzer {Landw. Hefte, No. 26 (1915), pp. 40, figs. 12). —

 3). — Methods of stacking silage are described. 



The use of straw for fodder {Bd. Agr. and Fisheries [London], Spec. Tjcaf- 

 let 47 {1915), pp. 7). — Data as to the composition and digestibility of wheat, 

 barley, oats, rye, bean, and pea straws are given, and rations in which straw 

 forms a part of the roughage are suggested. 



Oil seeds and feeding cakes (London: John Murray, 1915, pp. XXT-\-112). — 

 This book, with a preface by W. R. Dunstan, treats of the composition, nutri- 

 tive value, and uses of copra, palm kernels, peanuts, sesame seed, and mowrah 

 seed. 



The feeding of sugar-containing feedstufifs, Morgen (Wiirttemb. Wchnbl. 

 Landw.. No. 24 (1915), pp. 382, 383).=— Due to the low protein content of sugar- 

 containing feeds, such as sugar, molasses, and turf molasses, it is necessary 

 to supplement these material with such feeds as sesame cake, meat meal, 

 fish meal, or dried yeast when feeding to farm animals. It is suggested that 

 from 5 to 10 kg. of sugar and 4 to 5 kg. of molasses per 1.000 kg. of live 

 weight may be fed daily to swine, from 3 to 6 kg. of sugar and 2 to 4 kg. of
