ANIMAL PRODUCTION. 577 



chiefly by periodical measurements. In general during the first year the 

 greatest increase was in height, and the second year in length and breadth. 

 In the third year there was some Increase in breadth and a considerable in- 

 crease in flesh. * 



There are many references to the literature on the subject. 



Beef raising' in Canada, J. B. Spencer (Canada Dept. Agr., Branch Live 

 Stock Comr. Bui. 13, pp. 112, pis. 25, figs. 22; U. 8. Senate, Com. on Finance, 

 62. Cong. 1. Scss., 1911, pp. 118). — A special report of all phases of the beef 

 industry, made to the Canadian Minister of Agriculture and reprinted by 

 order of the Committee on Finance, U. S. Senate. 



Cattle in southern Rhodesia, R. Wallace {London, [1909], pp. 12, figs. 9). — 

 A description of the characteristics of the native Africander cattle and crosses 

 with European breeds. 



Outlines of modern sheep breeding', U. Telschow (Grundriss dcr neuzeit- 

 lichen Schafzucht. Hanover, 1911, pp. 232, pi. 1, figs. 82). — This work treats 

 of the anatomy and physiology of the sheep, the principles of breeding and 

 feeding, and the common diseases of sheep. It is written from the natural 

 history point of view, but so as to furnish information for the practical 

 breeder. 



Brood sows: Selection, feeding' and management, C. Christopher (Arkan- 

 sas Sta. Circ. 10, pp. Jf). — This circular contains information for the practical 

 swine breeder. 



Contribution to the knowledge of breeds of swine in the German Colonies 

 of the South Seas, M. Rauschke (Arch. Naturgesch., 77 (1911), I, No, 1, pp. 

 1-32, j}ls. 3). — A study of the origin and distribution of swine in the South 

 Sea Islands. 



From skeletal measurements the author comes to the conclusion that Sus 

 vittatus was the principal species of swine, S. niger and S. papuensis being only 

 superficially different from the modern representatives of S. vittatus. On the 

 Bismarck Archipelago and the Caroline Islands they are found mostly in a 

 feral condition while in the Mariana Islands a larger number are domesticated. 

 Some swine there seem to be a cross between S'. vittatus and the wild S. scrofa, 

 and one breed is apparently a cross between S. vittatus and Roman swine. 



A bibliography is appended. 



Lard from wild and domestic Philippine hogs and the changes in the 

 constants produced by feeding copra cake, H. D. Gibbs and F. Agcaoili (Phil- 

 ippine Jour. Sci., A. Chcm. and Geol. Sci., 5 (1910), No. 1, pp. 33-43). — Analyti- 

 cal constants are reported of lard obtained from the wild hog, native domestic 

 hogs, and an imported Chinese breed. 



" The variation in the constants of the lard of the Philippine wild hog from 

 the normal lard values is seen to be rather slight and is chiefly noticeable in 

 the low titer. The Koettstorfer number is slightly high. The iodin values, 

 while about normal, are decidedly lower than the constants given by Lew- 

 kowitsch for the wild boar which was a native of the Temperate zone. . . . 

 From the results of this work it is evident that lean hogs will deposit a body 

 fat with constants considerably influenced by coconut oil, when copra cake 

 forms only a part of the ration. When the ration is composed almost entirely 

 of copra cake the influence upon the constants is more remarkable." 



The fat of animals fed on cottonseed meal, J. Sanarens (Ann. Falsif., 4 

 (1911), No. 28, pp. 72-75). — This is a statement of the results of a chemical 

 and physical analysis of the butter, body "fat, and lard obtained from animals 

 fed cottonseed products. The results show that cottonseed oil was present 

 in practically all the animal products.
