There are also included analyses of rice polish, rice Ijraii, rice straw, and rice

Commercial feeding- stuffs of Pennsylvania in 1913; their chemical and 

 microscopical examination, J. W. Kellooo {I'enn. Dept. Agr. Bui. 2JfO (1913), 

 pp. 189). — Analyses are given of the following feeding stuffs: Cotton-seed meal, 

 linseed meal, dried brewers grains, gluten feed, middlings, mol;isses feeds, dried 

 beet pulp, corn chop, beef scrap, malt sprouts, buckwheat products, rye prod- 

 ucts, alfalfa meal, and various mixed and proprietary feeds. 



Breeds of beef cattle, AV. F. Ward (U. >S. Dept. Ayr., Fanners' Bui. (U.! 

 (1915), pp. 23. figs. 18). — This bulletin is a discussion of the breed character- 

 istics and utility value of the several breeds of beef and of dual-purpose cattle. 



The inheritance of twin calving in cattle, E. Uhlmann (Deut. Laiidic. 

 Tierzucht, 18 (191Jf), No. IJf, pp. 163, 161f). — In connnenting on the inheritance 

 of twin calving in cattle, an instance is given in which a cow gave birth to 

 twins. In the third generation, of the four heifers born, two gave birth to six 

 pairs of twins, and in the fourth generation two pairs of twins were bom. 



Corn silag-e compared with hulls for fattening steers, E. R. Lloyd (Mis- 

 sisftippi 8ta. Bui. 167 (lOl-i). pp. 3-8). — Four lots of .-^ix 4 to 5-year-old native 

 grade steers were fed 142 days, beginning December 1, as follows: Lots 1 and 

 2, cotton-seed meal, Johnson grass hay, and com silage; lots 3 and 4, cotton-seed 

 meal, Johnson grass hay, and cotton-seed hulls. Lots 1 and 3 were confined 

 under shelter, lots 2 and 4 had the run of the paddock. The average daily 

 gains per head were 0.77, 1.1, 1.13, and 1.38 lbs., respectively; the shrink in 

 shipping 4.65. 4.05, 5.42, and 5.42 per cent ; the cost per pound of gain 18.81, 

 11.12, 14.06, and 14.06 cts. ; the dressing percentage 59.32, 59.32. 59.01. and 59.01 

 per cent; and the profit per steer (manure not included) .$12.25, $15.87, $18.92, 

 and $22.07. 



The manure from the silage-fed steers analyzed as follows : Moisture 74.78 

 per cent, nitrogen 0.69, potash 0.76, and phosphoric acid 0.63; that from the 

 hull-fed steers, 78.5, 0.57, 0.61, and 0.38 per cent, respectively. That from the 

 former was estimated to be worth $4.32 per ton and that from the latter $5.41 

 per ton. 



Two lots of twelve 4 to 5-year-old steers of grade Jersey blood were fed 

 silage and cotton-seed meal and hulls and cotton-seed meal, respectively. The 

 average daily gains per head M-ere 1 and 1.19 lbs. ; shrinkage in shipping, 3.23 

 and 3.58 per cent; cost per pound of gain. 13.14 and 12.38 cts.; dressing per- 

 centage, 58.05 and 58.4 per cent; and profit per steer, $18.42 and $19.50, 

 respectively. 



The feeding and care of dairy calves ( U. S. Dept. Agr., Offiee Sec. Spec. 

 [Circ.'], 1914, Dec. 19, pp. .}). — Popular suggestions on calf feeding, with special 

 reference to cotton-belt conditions. 



Sheep grazing on ditches infested with Johnson grass, F. W. Wilson 

 (Arizona Sta. Rpt. 1913, pp. 268, 269). — From experiments conducted in coop- 

 eration with the LT. S. Reclamation Service it was found that the grazing of 

 sheep on irrigation ditches infested with Johnson grass lessened the stand of 

 grass ; the ditch banks were well packed ; the gopher holes and gophers seem- 

 ingly had disappeared ; the sheep had been maintained : the expen.se of 

 controlling the seeding of Johnson grass was cut to a minimum ; and the cost 

 of ditch cleaning was decreased. 



Producing sheep on southern farms (U. S. Dept. Agr., Office Sec. Spec. 

 [Circ.], 1914, Not\ SO, pp. 3). — General suggestions are given.
