cotton-seed meal, linseed meal, linseed-cake meal, flaxseed meal, Chicago gluten 

 meal, gluten feeds, dried brewers' grains, malt sprouts, wheat bran, ship stuff, hom- 

 iny meal or feeds, as well as a number of mixed feeds, cereal breakfast food by- 

 products, and condimental feeds. The results are arranged so as to compare the 

 different concentrated feeds, carbohydrate feeds, feeds made from whole grains, and 

 condimental feeds, and are discussed in detail. 



The law regulating the sale and analysis of concentrated feeding stuffs in 

 Wisconsin, W. A. Henry ( Wisconsin Sta. Bui. 89, pp. 8). — The text of the Wiscon- 

 sin feeding-stuff inspection law is quoted and discussed. 



A mechanical ration computer, W. J. Spillman ( Washington Sta. Bui. 48, pp. 

 7, figs. 3). — A mechanical device for calculating the amount of nitrogenous and nitro- 

 gen-free nutrients in any given ration is described, together with the method of 

 operating it. 



Steer feeding, G. H. Truk {Arizona Sta. Rpt. 1901, pp. 336, 5^7).— Continuing 

 previous work (E. S. R., 12, p. 1074) to determine the comparative merits of feeding 

 alfalfa hay alone and in combination with such materials as sorghum hay and hay 

 from cereal grains, 2 lots of 4 steers each were pastured on alfalfa and fed mixed 

 barley and alfalfa hay in addition. They gained 1.49 and 1.21 lbs., respectively, 

 per head daily in a period of 5 weeks' duration. Lot 1 was then fed alfalfa hay and 

 lot 2 wheat hay in addition to alfalfa pasturage for 9 weeks, the average daily gains 

 per head being 1.28 and 0.83 lbs., respectively. This test and the earlier work are 

 briefly discussed. 



"During the 33 weeks [of this and previous tests when] alfalfa only was fed against 

 combinations of alfalfa and other forages, the animals having only alfalfa gained 1.55 

 lbs. per day, while those receiving the combination gained 1.46 lbs. per day." 



Report of grazing and feeding tests. Beef cattle and lambs, R. S. Shaw 

 {Montana, Sta. Bui. 31, pp. 20, pis. 6). — Experiments vAth steers (pp. 3-10). — The value 

 of alsike pasturage was tested with 12 high-grade Shorthorn and Hereford yearling 

 steers and 7 grade Jersey heifers. The animals grazed on an alsike pasture covering 

 5.04 acres, which was divided into 2 lots irrigated alternately during the early part 

 of the summer. The test closed the first of October, the steers having been pastured 

 108 days and the heifers 93 days. The average gain of the steers per head per day 

 was 2.75 lbs., and of the heifers 1.69 lbs. Rating the gains at 4 cts. per pound, the 

 author calculates that there was a cash return of $36.19 per acre. The possible dan- 

 ger from bloating is spoken of. As the author notes, it is claimed by many that 

 alsike is less likely to cause bloating than alfalfa or red clover. 



A test to study the possibility of profitably feeding cattle under local conditions is 

 also reported. Thirty-one steers (including those in the previous test) were pastured 

 at the station farm from the first of October until November 13, on 112 acres of 

 stubble, 57 of which were clover. They were then divided into 1 lot of 11 steers and 



2 lots of 10 steers each. The selections were made so that lot 1 (steers used in the 

 pasture experiment) showed the largest infusion of beef blood; lot 2, very nearly the 

 same amount; while lot 3 was inferior. The 3 lots were fed for 137 days clover and 

 barley meal, the average daily gain per head being 2, 1.75, and 1.71 lbs., respectively, 

 the corresponding cost of food per pound of gain being 4.85, 5.16, and 5.31 cts. The 

 steers were sold for slaughtering. Considering the test as a whole, the author states 

 that there was a net profit of $3.95. 



Lamb-feeding experiments (pp. 11-19). — Continuing earlier work (E. S. R., 12, p. 72) 



3 feeding tests with lambs are reported. The comparative advantages of feeding 

 marketable grain of good quality and screenings in addition to clover was tested with 

 3 lots of 53 lambs each. Lot 1 was fed clover with a grain ration of oats and barley 

 of good quality, lot 2, clover hay and screenings, while lot 3 was fed clover hay 

 only. In the 89 days of the test, which closed February 13, the average gains made 

 by the 3 lots were 24.96, 28.08, and 21.15 lbs., respectively. Lot 1 consumed per head
