Suggestions sent to the State institutions of California for food conserva- 

 tion in accordance with the proclamation of the United States Food Admin- 

 istration, M. E. Jaffa (Cal. Bd. Health Mo. Bui., 13 (1918), No. 9, pp. 417- 

 422). — Suggestions are given for conserving food in hospitals, prisons, reform 

 schools, and homes for the feeble-minded according to the suggestions of the 

 U. S. Food Administration. The suggestions are arranged according to food

The effect of omnivorous and vegetarian diets on reproduction in the 

 albino rat, J. R. Slonaker and T. A. Card {Science, n. ser., 47 (1918), No. 

 1209, pp. 223, 224). — Results are given of an experiment now in its fifth year 

 to show the effect of a vegetarian diet as compared with an omnivorous diet 

 on reproduction in the albino rat. The general conclusion reached is that a 

 vegetarian diet not only reduces the vitality, the growth, and the ability to 

 reproduce, but tends to the extermination of the race. 



ANIMAL PRODUCTION. 



[Velvet beans compared with cottonseed meal, corn, and dried blood for 

 live stock] (Alabama Col. Sta. Bui. 19S (1917), pp. 103-122) .—In. this con- 

 tinuation of work previously noted (B. S. R., 36, p. 563), three experiments 

 are reported. 



I. Velvet heans compared with cottonseed meal -for fattening steers, by G. S. 

 Templeton and E. Gibbens (pp. 103-109). — In this experiment, carried out in 

 the winter of 1916-17. the steers were of different quality and the velvet beans 

 were prepared in another way from the previous year. The animals averaged 

 773 lbs. in weight at the beginning of the experiment which lasted 137 days. 

 They were in lots of 15 each. The beans were fed in the pod mixed with the 

 silage. After four weeks they were soaked in water 12 hours before feeding. 

 The local prices of the feeds were, cottonseed meal $38, velvet beans in pod 

 $20, and corn silage $3 per ton. 



The lot of steers on velvet beans in pod and corn silage for 119 days gained 

 an average of 1.6 lbs. each daily at a cost of 9.3 cts. per pound of gain, and 

 the lot on cottonseed meal and corn silage gained an average of 1.55 lbs. each 

 daily at a cost of 10.42 cts. per pound of gain. 



The steers cost 6 cts. per pound when put on feed, and the velvet bean 

 lot was sold at 9.75 cts. per poimd, netting a profit of $19.62 each. The 

 cottonseed meal lot sold for 9.4 cts. per pound and returned a profit of $16.39 

 each. 



In this experiment 1 lb. of cottonseed meal was equal to 2.05 lbs. of velvet 

 beans in pod. The velvet bean lot, however, consumed only two-thirds the 

 amount of silage as the cottonseed meal lot. The velvet bean ration was 

 relished by the animals. 



II. Velvet beans v. cottonseed meal as feeds for dairy cattle, by G. S. Tem- 

 pleton and H. C. Ferguson (pp. 110-117). — -The ob.iect of the experiment was 

 to determine the value of velvet beans in the production of milk and milk 

 fat and the relative cost compared with cottonseed meal. Two lots of five cows
