variety of circninstances. The profits per flock, including receipts from both 

 wool and lambs, ranged from $9.47 to $118.56. 



Production of wool in Spain, F. T. F. Dumont (Dnihj Cons, and Trade 

 Rpts. [U. 8.], 16 {1913), No. 100, pp. 5U, 5^5).— This is a report of sheep and 

 wool production in Spain and its relation to American import trade. 



Fat lambs at Buakura, P. McConnell (Jour. Agr. [New Zeal.], 6 {1013), 

 No. 3, pp. 271-275, figs. 6). — A report of breeding experiments with 600 Lincoln 

 Homuey ewes, half of which were bred to Border Leicester rams and half to 

 Southdown rams. The gross profits realized from the lambs of the Leicester 

 cross in addition to the wool receipts were $5.31 per ewe, as compared with 

 gross profits of $6.04 per ewe from the Southdown cross. 



In a comparison of the live and dressed weights of a lamb from both crosses 

 the Leicester cross gave 98 and 64 lbs., and the Southdowns 78 and 48 lbs., 

 respectively. The Southdown carcass was superior in quality.

 Nos. 2029, pp. 176, 177; 2036, pp. 378, 379; 2038, pp. J,31, 1,32; 2039, pp. JfSS, .',59,

 breeding on the prepotency, fertilizing power, size, and character of stallions. 



Alfalfa hay for horses, A. D. Faville {Wyoming 8ta. Bui. OS, pp. S). — This 

 bulletin reiwrts that experiments with 6 horses fed during 10 one-month 

 periods on alfalfa hay " showed a total gain of 203 lbs., while during an equal 

 period on native hay there was a total loss of 84 lbs." Analyses of Wyoming 

 alfalfa and native hay are included. 



Fattening' hog's in Alabama, D. T. Gray, L. W. Summers, and L. W. Shook 

 (Alabama Col. Sta. Bui. 168, pp. 233-28.',, figs. IJ,). — In exi>eriments covering a 

 period of 2 years, comparing the feeding value of i>eanut pasture and dry feeds 

 for pigs weighing from 40 to 60 lbs., a ration consisting of peanut pasture and 

 corn and tankage, 4:1, gave better results both in average daily gain and in 

 cost of feed than dry feeds composed of com alone, corn and tankage, or corn 

 and cowpeas (seeds). During 1911-12 Ihe estimated total value of pork made 

 on each acre of peanuts, after deducting the cost of concentrates, ranged from 

 $30.32 to $40.08, and the carrying capacity per acre ranged from 45 to 56 days 

 for 10 pigs. During 1912-13 the value of pork made ranged from $17.29 to 

 $25.07 per acre, and the carrying capacity per acre per 10 pigs, from 32 to 42 

 days. 



Experiments vdth similar pigs comparing dry-lot feeding during the mid- 

 winter months with a grazing system of feeding gave the following results: Lot 

 1, fed com and tankage 4:1 made an average daily gain per head of 0.91 lb., 

 costing 5.86 cts. per pound of gain. Lot 2, fed com and tankage, and rye 

 pasture, gained correspondingly 0.63 lb., costing 4.34 cts. per pound ; and lot 3. 

 fed com and tankage and rape pasture, 0.68 lb., costing 4.04 cts. per pound. 

 The estimated value of 1 acre of rye pasture in terms of corn and tankage was 

 $4.21, and of rape pasture, $14.01. 



A one-half grain ration proved to be preferable to a one-fourth grain ration 

 as a supplement to pasture. With the former the estimated total pork pro- 

 duction of rape per acre was 607 lbs., and with the latter 455 lbs. During Ihe 

 finishing period following these forage experiments, the lot fed the one- fourth 

 grain ration made 1.05 lbs. average daily gain per head; that on the one-half 

 grain ration, 0.8 lb.; and the lot on a full grain ration, 0.81 lb. However, in 

 another experiment these results were reversed, for during a finishing period of 

 28 days greater and more economical gains accrued from those previously dry- 

 lot fed. 



Experiments were made to demonstrate the advantages of cowj^ea pasture. 

 On a ration consisting of com and tankage 9:1, and cowpea pasture, there was
