 Presse, 23 [1890), Xo. 101. pp. S95, 890).— X general :irticle. 



Feeding experiments -with prickly pear {Agl. Gaz.N.S. Wales, 7 (1896), Xo. 10, 

 pp. 658, 059). — Prickly pear was cooked with meat refuse or with a little molasses and 

 fed for a long period to pigs with favorable results. 



The substitution of barley for oats as food for horses, H. Ha:\ibro {Dent, landw. 

 Presse, 23 (1890), Xo. 100, p. 891). — A general discussion showing that barlej' may he 

 substituted for oats in feeding horses, with a brief report of a test with horses made 

 by the Birmingham corporation in which barley and oats were compared. 



Rational stock feeding, H. P. Akmsijy (PeDnsi/lrania Sta. Bpt. 1895,pp. 16-2S). — 

 Reprinted from the Annual Report of the station for 1894 (E. S. R., 7, p. 985). 



Comparative experiments in feeding cattle, G. Cormouls-Houlks (Prog, Agr. et 

 Vit.,25 (1896), Xo. 25, pp. 693-095). — A brief report is given of feeding experiments 

 with 5 lots of 4 steers weighing about 1,600 kg. each, to test the comparative value 

 of wheat, rye, potatoes, and ccttou-seed cake. Among the conclusions reached were 

 the following: Cotton-seed cake is more economical than grains, especially wheat. 

 It is more advantageous to feed potatoes than to sell them to the distilleries. 



Rouen ducks, Leroy (Jour. Agr. Prat., 61 (1897), I, Xo. 7, pp. 241-246). — A general

Influence of the quantity of food upon the economy of milk 

 and butter production, H. .1. Waters and E. H. Hess (Pennsylvania 

 Sta. Upi. 1S9.5, pp. 2i-5-5). — An experiment was made with 9 cows, 

 mostly Jerseys and grade Guernseys, histiiig loO days and divided into 5 

 periods of 30 days each. In all the periods the food consisted of mixed 

 hay and corn stover ad libitum., with varying amounts of a grain mix- 

 ture consisting of 7 parts of corn meal and 3 of cotton-seed meal. On 

 the first 10 days in each period a digestion experiment was made witli 

 3 cows selected as representing the lot. From the results the amounts 

 of digestible ingredients consumed were calculated for each cow in each 

 period. These data, together with the yield and fat content of the milk 

 and the calculated yield of butter, and the financial results are fully 

 tabulated and discussed. The financial results are based on corn meal at 

 $20, cotton-seed meal at $26, mixed hay at $12, and corn stover at $4 

 per ton; butter at 30 cts. per pound, and solids-not-fat of the milk at 

 2 cts. per pound. The financial results are shown graphically. A 

 summary showing the amount of the grain mixture fed in each period 

 and the results is given below :
