beans 183.1 pounds, $10.99, respectivelj' The results with soy beans are from 

 the 1910 test only, the 1909 results being discarded on account of poor stand. 

 In hogging off experiments with rye the average amount of pork produced per 

 acre was 244.4 ix)unds at a net profit of $14.66 per acre, and the corresponding 

 amounts for corn were 395.2 pounds and $23.71. 



Among other conclusions drawn are the following: Blue grass made more 

 profitable gains in May and June than later. Red clover ranked among the 

 first as a hog forage because of the palatability of the feed throughout the 

 season, and also because of its adaptability to rotations. Rape fitted in well in 

 hog forage crop rotation, if clover was sown with it for the following year. 

 First growth sorghum was adaptable for hogs, and furnished excellent feed 

 through July and August, when other forages were affected by dry weather. 

 Gains made on forage were made at 20 to 30 per cent less cost than gains pro- 

 duced with grain and dry lot feeding. Where forage and grain crops were fed 

 on the land which produced them the minimum amount of fertility was re- 

 moved, and the physical condition of the soil improved. 



[Forage crops for pig's] {Oreg. Agr. Col. Bui., 1. ser., 1911, No. JfS, pp. 68- 

 70, figs. 2). — In tests made at the Eastern Oregon substation, hogs when 

 feeding on field peas in the field made an average daily gain per head of 1.52 

 pounds, and produced 256.5 pounds of pork per acre, while the corresponding 

 figures with field peas and hull-less barley were 1.12 pounds per head and day 

 and 190 pounds per acre. The peas were more palatable than the barley, the 

 latter not being eaton until tlie available peas were gone. 



Pig feeding experiments, J. L. Duncan (Dcpt. Agr. and Tech. Int^tr. Ireland 

 Jour., 11 {1911), No. 2, pp. 303-310). — This is a continuation of previous work 

 (E. S. R., 21, p. 473). 



The gains with 4 lots of 8 pigs each were as follows: On a meal mixture of 

 maize, barley, and pollard, plus potatoes and separated milk the average daily 

 gain was 1.7 pounds, with a total profit on the lot of £6 6s. 3d.; on the meal 

 mixture and separated milk 1.7 pounds, with a profit of £7 13s. 4d. ; on the meal 

 mixture and potatoes 1.23 pounds, at a profit of £3 Is. 3d. ; and on the meal 

 mixture plus coconut meal, potatoes, and separated milk 1.5 pounds, at a 

 profit of £4 10s. 7d. 



On the 5 separate experiments conducted during the last 4 years, wherever 

 there was a slight advantage it was in favor of the lot that was fed the meal 

 and milk only. The coconut meal did not appear to warrant the extra price 

 paid for it. 



Pig feeding experiments, B. N. Wale (Jour. Southeast. Agr. Col. Wye, 1909, 

 No. 18, pp. 26, 27). — Foreign barley gave better returns than English barley 

 for ix)rk production, on the average 0.25 pound less of the foreign barley being 

 required for each 1 pound gain in live weight. Coal slack proved a valuable 

 supplement to the grain ration when fed in small amounts. 



Feeding experiments with invert potato flakes, Klein (Milchw. ZentM., 7 

 {1911), No. 2, pp. 70-7. 't). — As in a previous experiment (E. S. R., 23 p. 476) 

 there was found to be no advantage in inverting potatoes flakes with diastasolin 

 for feeding to pigs. 



A note on the feeding value of coconut and peanut meals for horses, G. M. 

 Rommel and W. F. Hammond {U. S. Dept. Agr., Bur. Anitn. Indus. Circ. 168, 

 pp. 2). — In a test with Morgan yearlings and heavy work horses, lasting about 

 four months, in which coconut meal and peanut meal in the proportion of 

 2:1 were substituted for one-half or the entire oat ration, the yearlings 

 showed somewhat larger and cheaper gains on the coconut and peanut meal, 

 those having all their oats replaced giving the best returns. The results were
