CaUlo in tlie [Soutli AfricanJ Union. — Thft trado in beef {Union So. 

 Africa. Dept. Aijr. Jour., 1 (10.10), No. 3, pp. 278-280).— Statistics of the uuuiber 

 of cuttle ill the four Provinces of the Union of South Africa, and the imports 

 and exports of beef since 1903 are presented. Since 1915 imports have been 

 r.egllKil>le, while exports have greatly increased. 



Mana^inj; sheep on North Dakota farms, W. F. LaGrange {N. Dak. Aqr. 

 Col. Ext. Circ. 35 (1920), pp. 23, figs. IJ^). — The purchase of stock, sale contracts, 

 feeding for market, breeding and the care of pregnant ewes, wintering the

 parasites by P. JFcMnhan.

 Agr. Col. Ert. Circ. 79 (1920), pp. 11, fig. 1). — Wool auctions, regional or State, 

 are advocateil in place of county pools. 



[Hog grazing in Louisiana], A. F. Kidder and G. D. Cain (Louisiana Stas. 

 Rpt. 1919, pp. 16, 3'/). — At Baton Rouge the following results were obtained in 

 a practical lioggiug-off test in 1919: (1) A 2-acre plat of corn and peas (esti- 

 mated yield, 28 bu. corn and 5.5 bu. peas per acre) produced 620 lbs. of pork; 

 (2) a 2.75-acre plat of sweet potatoes (55 bu. per acre) and 4.25 acres of corn 

 (9.5 bu.) and soy beans (5 bu.) produced 1,423 lbs. of pork; and (3) a 2-acre 

 plat of sweet potatoes (140 bu.) and 3.25 acres of soy beans (8 bu.) plus 12 

 bu. of corn produced 1,617 lbs. of pork. There were 35 hogs used and the feed- 

 ing period lasted 83 days. 



At the North Louisiana Substation, a group of 52 shotes and pigs gained 350 

 lbs. In a week on a 1.5-acre plat of cowpeas. A group of 50 shotes and pigs 

 gained 700 lbs. in 24 days on 4.45 acres of corn yielding 25 bu. per acre. 



[Hog feeding trials at the Scottsbluff Substation] (Nebraska Sta. Rpt. 

 1919, pp. 29, 30).— A. lot of 10 shotes on a full feed of corn and with access to 

 an acre of undivided alfalfa pasture gained 1,452 lbs. in 90 days, consuming 

 3.7 lbs. of corn per pound of gain. A second and third lot received a 2 per cent 

 corn ration for the first 60 days, a heavier ration (increasing to 3 per cent) 

 the next 30 days, and a full feed of corn the last 30 days. Lot 2 had access to 

 an undivided plat of alfalfa and made a total gain of 1,133 lbs. during the 120 

 days. Lot 3 had access to a divided half acre plat of alfalfa and gained 1,168 

 lbs. in 120 days. Lots 2 and 3 required, respectively, ^.85 and 3.92 lbs. of corn 

 for a pound of gain. 



In a 2-year experiment it was found that shotes on Turkestan alfalfa con- 

 sumed 3.06 lbs. of corn per pound of gain, while those on common alfalfa con- 

 sumed only 2.91 lbs. Total gains were also less on the Turkestan plats, and 

 it is concluded that the use of this variety for hog pastures is not economical 

 although hogs show a decided preference for it. Similar results have recently 

 been reported from the Huntley (Montana) Reclamation Project Experiment 

 Farm (E. S. R., 43, p. 465). 



A third experiment was a comparison of methods of preparing barley for 

 pigs on alfalfa pasture. It took 3.29 lbs. of soaked whole barley or 2.77 lbs. 

 of ground barley to produce a pound of gain. 



Buying !»og feeds cooperatively, R. C. Ashby (Swine World, 8 (1920), No. 

 t, pp. 81, 88). — A sununary of the cooperative purchases of hog feeds in 16 

 States. In some cases the buying was done through farm bureaus. 



The Chinese hog and Poland Chinas, H. H. Yao (Swine World, 8 (1920), 

 No. 1, pp. 63, 6/f). — The author presents a few notes on hog raising in China 

 and predicts a demand for imported Poland China boars to grade up the native 

 black hogs. Chinese hogs are not fattened previous to slaughter, partly because 

 little grain is available for feeding purposes and partly because the public 

 seem to prefer lean meat.
