Oats for horse feeding, M. Rasquin {Jour. Hoc. Agr. Brabant ct Hahiaut, 

 52 (1907), \(i. 'lO, pp. !h^,i-!)8.'f) . — A summary of data on the importance of oats 

 as a feeding stuff, [lartieular attention being devoted to crushed oats. 



The use of prickly pear as cattle fodder {Cent. Agr. Com. Madrat;, liul. .) ; 

 ahs. in Agr. Jour. India, 2 {1901), No. 3, pp. SOJ/, 305). — A summary of experi- 

 mental work, most of which has been carried on in the Madras and Bombay 

 Presidencies, on the value of prickly pears as a cattle fodder. The results are 

 contradictory and it is believed that further investigation is necessary to deter- 

 mine " whether this plant can be satisfactorily fed to all Indian breeds of cattle 

 as a supplement to other food stuffs in time of famine." 



Feeding experiments with swine, G. Nannes {Nord. Mcjcri Tidn., 22 {1907), 

 A' OS. 37, pp. ■'i3o-.'f3S; 38, pp. .'///7, -'/.'iS). — The paper gives a report of a feed- 

 ing experiment with 31* pigs, separated into 9 lots, and fed various mixtures of 

 feeds, viz: Ground oats; ground oats with peanut cake meal; ground oats, peii- 

 nut cake meal, and molasses feed or " molasin " ; gluten feed, ground oats and 

 molasses feed; and germ oil meal and molasses feed, both with and without 

 ground oats. Potatoes were fed to all the lots. The pigs averaged 40 to 55 kg. 

 per head in the different lots at the beginning of the trials, which lasted about 

 30 days on the average. 



The lot fed gluten feed made the highest gains, viz, 0.67 kg. per head per day, 

 while the most profitable results were obtained with the lot fed ground oats and 

 potatoes. The gain per 1,000 kg. live weight for the gluten-feed lots w;is 17.31 

 kg. and for the gei"m-oil-meal lots 14.38 kg., a difference of 20 per cent in favor 

 of the former feed. 



Recent experience as to the utilization of kitchen refuse for swine feeding, 

 S. P. Nyst{:dt {K. Landthr. Akad. Handl. och Tidskr., .'i6 {1907), No. Jf-o, pp. 

 335-350). — A paper containing a condensed statement of the experience in 

 C4erman, American, and Swedish cities with kitchen refuse as a swine feed. 

 The amount fed ranged from to 10 kg. per head per day. The economic im- 

 portance of the utilization of this refuse in modern cities is considered. 



Experiments at the Proskau Dairy Institute on feeding pigs with starch 

 hydrolyzed with diastasolin, J. Klein {Dcut. Landw. Prcssc, 3Jt {1907), No. 

 80, p. 636). — In an article quoted from the report of the German Pig Breeders' 

 Association the data summarized show that very nearly the same gains were 

 made on starch treated with diastasolin as on untreated starch and on [)otato 

 flakes, and the conclusion is reached that in pig feeding skim milk and starch 

 treated with a saccharifying ferment did not give so good results as in calf 

 feeding. 



Principles of breeding, 11 Davenport {Bo.^ton, Nciv York, Chicago, and Lon- 

 don, 1907, pp. Xiy-\-727, figs. 52, dg)ns. S). — In this volume, which discusses 

 variation, causes of variation, transmission, and pi'actical problems with refer- 

 ence to animal breeding, a large amount of information has been summarized, 

 discussed, and made available fort the student, and the volume as a whole con- 

 stitutes a useful handbook for agricultural college and experiment station 

 work and also for the practical breeder of farm animals. 



" The general purpose has been first of all to define the problems involved 

 in animal and plant improvement; to free the subject from the prejudice and 

 tradition that have always befogged it; to bring to the study whatever facts 

 are fully known to biological science; to recognize and define somewhat clearly 

 the present limitations of knowledge, and to indicate as well as may be the 

 directions from which further and much-needed light is most likely to come.
