 Immigr. Va., Dairy atid Food Div. Dul. IJj, 1910, pp. 118-152). — Analyses are 

 reported of wheat bran and middlings, ship stuff, red dog flour, rye middlings, 

 corn chop, cottonseed meal, corn bran, hominy feed, oil meal, gluten feed, 

 malt sprouts, rice hulls, barley chaff, flax bran, peanut meal, and mixed feeds. 



Report of the activities of the Pommritz Agricultural-Chemical Experi- 

 ment Station, 1910, Loges (Bet: Agr. Chem. Vers. Stat. Pommritz, 1910, pp. 

 10). — Analyses are reported of rye bran, barley bran, maize products, rice meal, 

 distillery slop, millet bran, brewers' gi'ains, malt sprouts, corn germ meal, 

 meat meal, and the following cakes: Linseed, turnip, peanut, coconut, sun- 

 flower, palm nut, sesame oil, hemp, and soy bean. 



Fish guano and its use as feed, R. P. Skinner (Daily Cons, and Trade Rpts. 

 [U. S.], l-'t (1911), No. 103, p. 512).— 'Notes on the use, extent, and value of fish 

 meals as feed for live stock are presented. 



Report of animal husbandry, H. H. Simpson (New Mexico Sta. Rpt. 1910, 

 pp. 32-36). — In a feeding test with steers the gains per head and day were as 

 follows: On alfalfa 1.84 pounds at a cost of 3.92 cents per pound; on alfalfa 

 and corn stover 1.17 pounds at a cost of 4.01 cents per pound; on alfalfa and 

 corn meal 2.58 pounds at a cost of 7.33 cents per pound ; and on alfalfa 60 days 

 with corn as a supplement the last 30 days 2.06 pounds at a cost of 5.55 cents 

 per pound. 



Dairy cows kept on pasture and fed 6 pounds of grain per head and day, 

 produced more milk than cows on the same pasture not fed grain, but the 

 grain increased the cost per quart of milk by 0.82 cent. 



Thirty-two pigs on alfalfa pasture made average daily gains per head as 

 follows: Without supplement 0.254 pound, with 8 pounds of grain per day 

 0.657 pound, with 16 pounds of grain per day 0.73 pound, and with 64 pounds 

 of skim milk per day 0.597 pound. The largest returns per acre for pasture 

 were on the lots which were fed grain as a supplement. 



Some methods of incubation of eggs were studied, with the following results : 

 ■' It was found that by sprinkling the eggs during the last 3 days one-third 

 more eggs were hatched, and the eggs that were sprinkled from the third day 

 on gave about 10 per cent better hatch. Submerging the eggs did not seem 

 to increase the hatch as much as siirinkling. 



" While it is comparatively easy to develop the chicks in the large, thick- 

 shelled, dark, Brahma eggs, it is very difficult to get a good hatch. From 

 examination it was found that about 70 per cent of the large, heavy eggs that 

 failed to hatch contained fully developed chicks." 



Bullock feeding experiment, G. B. Pinyon and B. N. Wale (Jour. Southeast. 

 Agr. Col. Wye, 1909, No. 18, pp. 21-25). — Molascuit gave better results in a 

 Steer-feeding experiment than jn a similar experiment the preceding year
