 ing,' test conductid in 1917 (E. S. II., 39, p. S79) wiis repeated in 1918. From 

 Ai)ril 24 to September 9 tlie six ewes ou tlie four (luarter-acre plats made a 

 tolal gain of OU ll)s. and their lambs j;alned 314 lbs. Ten ewes were carried 

 from Septen)ber 10 to October 21 without increase in weijrht, althougli they 

 remained in f^ood condition. 



Swine e.xperiments [at \orth Carolina Station], D. T. Gray (North Caro- 

 lina Sta. Rpt. 1919, pp. 43-J/7y. — Results of several experiments conducted by 

 E. Hostetler are briefly reported, including those on mineral mixtures noted 

 below. 



In a 119-day test begim April 23, 1919, a lot of hogs fed corn and fish meal 

 (9:1) made a daily gain of 1 lb. per head, while the chock lot fed corn and 

 tankage (9:1) averaged 0.95 lb. per head. 



Two grazing experiments were made in connection with soft pork investiga- 

 tions. In the first test (57 days beginning October 10, 1918) a lot fed corn 

 and shorts (2:1) without pasture made a daily gain of 0.32 lb. per head, a 

 lot on soy bean pasture plus the same grain mixture gained at the rate of 

 0.4G lb., a third lot on soy bean pasture without supplement gained 0.41 lb. 

 per day, and a fourth lot on peanut pasture without supplement gained 0.C2 lb. 

 Tiie pastures were in poor condition. In the second test (52 days beginning 

 Oclobei 28, 1918) the same grain mixture was used and the lots on pasture 

 received a half feed of grain. Pigs not on pasture gained 0.46 lb. per head 

 daily, those on soy bean pasture gained 0.46 lb., and those on peanut pasture 

 0.9 lb. Samples of lard were collected from the pigs in both tests, but the 

 chemical analyses had not been completed. 



" In onr work meat cured from hogs which never had peanut or soy-bean pas- 

 ture shrank 19.4 per cent ; cured meat from hogs which were grazed upon soy 

 l>eans shrank 20.6 per cent; meat made from hogs fattened upon peanut pas- 

 tures shrank during the curing process 16.9 per cent." The claim of packers 

 tliat hogs fed on soy bean and peanut pastures shrink much more in curing 

 than those fattened on corn alone is, therefore, considered untenable. It is 

 also noted that a proprietary " liquid smoke " produced substantially the same 

 shrinkage in an experimental test as hickory smoke. 



Two other grazing experiments were conducted, the grain mixture in all 

 cases being corn and shorts (2:1). In a 4S-day test beginning March 28, 1919, 

 one lot on bur clover (17 to an acre) were given an average ration of 1.03 

 lbs. of grain per head, while the check lot not on pasture consumed 1.89 lbs. 

 per head daily. The gains per head were the same in both cases, viz, 0.17 

 lb. per day. In a 112-day test beginning May 27, a lot on a permanent Ber- 

 muda grass pasture consumed an average ration of 2.46 lbs. of grain and the 

 cheek lot (not on pasture) 2.94 lbs. The daily gains per head were, respectively, 

 0.41 and 0.42 lb.

 in 1918], D. Hansen (U. S. Dcpt. Agr., Dept. Circ. 86 {1920), pp. 18-25, fig. 

 1). — Records of the utilization by hogs of the crops in irrigated rotations in 

 1918 and the results of several swine feeding experiments are reported. Both 

 series of investigations followed in general the plans outlined for the pre- 

 ceding years (E. S. R., 39, p. 878). The past results in the crop-utilization 

 tests are also tabulated. 



A quarter-acre plat of alfalfa in each of two rotations (numbered 67 and 

 69) furnished pasture for 5 fall pigs and 8 spring pigs in succession for a 

 total of 148 days, the pigs being fed a 2 per cent corn ration. The gains
