cakes. It showed no sign of deterioration not equally marked with the other 

 cakes, except linseed cake and, possibly, soy cake. 



Data on the digestibility of palm-kernel cake and extracted palm-kernel meal 

 and undecorticated cottonseed cake are reported by H. E. Woodman, as ob- 

 tained with two sheep. The differences of digestibility between the palm- 

 kernel cake and meal were slight, but the palm-kernel meal may be regarded 

 as worth 23 per cent more and the palm-kernel cake 35 per cent more than 

 cottonseed cake. 



In a study of the influence of palm-kernel cake upon the yield and composi- 

 tion of milk, reported by A. G. Ruston, five cows w-ere fed on pasture. The 

 results were variable. There was a gain in live weight of the animals while 

 on cake, a favorable influence upon the production of milk fat, and a slight 

 increase In the fat content of the milk. 



In a report of the influence upon the composition of the milk fat, made by 

 H. Woodhouse, the results of analyses are shown indicating the passage of 

 some ingredient of the palm-kernel oil into the milk fat. This renders probable 

 the conclusion that the effects upon the output can be attributed thei'eto. 



Feeding stuffs of minor importance, F. W. Woll {California Sta. Circ. 167 

 (1917), pp. 7). — The object of this circular is to describe briefly some materials 

 which, while not generally used, may be employed as feeding stuffs, because of 

 the scarcity and high prices prevailing for hay and other common feeding 

 stuffs. The following are discussed : Cereal straw, rice straw, legume straw, 

 foxtail, Indian-corn stalks, stalks of grain sorghums, cannery refuse, sugar- 

 beet tops and leaves, cull potatoes, potato tops, orchard products, acorns, and 

 spineless cactus. 



Utilization of farm wastes in feeding live stock, S. H. Ray {U. S. Dept. 

 Agr., Fanners' Bui. 873 (1917), pp. 12). — The need of a more efficient use of 

 straw, corn stover, and cottonseed meal is pointed out, and rations containing 

 these pi-oducts are listed for cattle, sheep, and horses. 



Animal industry: The problems confronting it during and after the war, 

 C. Pucci (Bol. Quind. Soc. Agr. Ital, 22 {1917), No. 7-S, pp. 172-182).— A paper 

 and discussion relating to the industry in Italy. A better utilization of fodders, 

 by-products, etc., is advocated, and closer organization of those engaged in 

 live-stock production is urged as a means of bettering present conditions and 

 solving the problems that will arise after the war. 



The sheep industry on the Minidoka reclamation project, E. F. Rine- 

 HART {U. S. Dept. Agr. Bui. 573 {1917), pp. 28, figs. 7).— This report treats 

 briefly of the agricultural conditions on this reclamation project and in detail 

 of the history and present status of the sheep industry, methods of sheep man- 

 agement, and the future development of the industry. The suggestions made 

 in this bulletin, while based primarily on the results of observations on the 

 Minidoka reclamation project, are deemed applicable to several other irriga- 

 tion projects in the northwestern United States having similar climatic and 

 agricultural conditions. 



Ration experiments with swine, A. D. P'aville {Wyoming Sta. Bui. 114 

 {1917), pp. 8). — Fifteen pigs averaging 87 lbs. each were divided into three 

 lots and fed as follows : Lot 1, ground barley ; lot 2, ground barley and meat 

 meal 9:1; and lot 3, ground rye. The grains were valued at $25 per ton, the 

 meat meal at $55. The pigs were bought at $7 per hundredweight and sold 

 for $9.40. They were fed in the experiment for 70 days. 



Lot 1 made an average daily gain of 1.46 lbs., requiring 4.13 lbs. of feed per 

 pound of gain and costing 5.16 cts. Lot 2 gained 1.74 lbs. daily with 3.33 lbs. 

 feed per pound of gain, costing 5.18 cts. Lot 3 gained 1.53 lbs. daily with 3.4S 

 lbs. feed per pound of gain, costing 4.35 cts.
