and Plant Diseases, 3 (1912), No, 8, p. 1817). — The characteristics of the East 

 Friesland milk sheep are discussed, and there is a general account of the recent 

 efforts to improve tlie breed. 



A comparison of sheep branding paints, C. J. Oviatt {Wyoming Sta. Bui. 

 93, PI). 8, figs. 6). — This bulletin reports the results of tests for the purpose of 

 ascertaining the comparative efficiency, durability, and scouring-out qualities 

 of several commercial brands of sheep branding paints. 



Paints remained a greater length of time on downs and fine wools than on 

 coarse wool. The fineness of the wool had no effect on the scouring-out quali- 

 ties of the paints. It is stated that if all wool growers would use a scourable 

 paint the labor of clipping brands from the fleeces in the mills would be elimi- 

 nated and this saving could be added to the price of wool. 



"A paint made of Venetian red or lamp black as pigments mixed with lin- 

 seed oil is much more durable than the prepared paints tested. The right 

 consistency may be obtained by the addition of turpentine." 



Heredity in goats, C. J. Davies (Mendel Jour., 1912, No. 3, pp. 104-ilG, figs. 

 6). — Data are presented from herd books of the British Goat Society on the 

 inheritance of horns and hair. 



Dried yeast as a food for fattening swine, W. Volk (Ztschr. Spiritusindus., 

 35 (1912), Nos. 1, pp. 1, 2; 2, pp. U,, 15; 3, pp. 25, 26; J,, p. 38; 5, pp. 48, 49; 

 Wchnsclir. Bran., 28 (1911), Nos. 45, pp. 537-541; 46, pp. 550-556, figs. 3; a&s. 

 in Ohem. ZentU., 1912, I, No. 7, p. 515). — The average daily gain of 9 pigs for 

 li months on a ration of dried yeast, potatoes, and barley was about 0.77 kg. 

 (1.69 lbs. per head per day at a cost of 0.545 marks (13 cts.) per day. 

 Analyses of feeds and the slaughter weights of different organs are given. 



Swine fattening experiments with soy-bean meal, E. Haselhoff (F-Uhling's 

 Landw. Ztg., 61 (1912), No. 12, pp. 401-414)-— Soy-bean meal was found to be 

 somewhat cheaper than barley meal as a feed for swine when given with a 

 variety of other feeds. Studies of the fat showed that soy-bean meal had no 

 great effect on the index of refraction, saponification number, or iodin number. 



Fattening pigs, J. W. Wilson (South Dakota 8ta. Bui. 136, pp. 339-350, 

 fig. 1). — To determine the comparative value of buttermilk, sweet skim milk, 

 and sour skim milk when fed in connection with corn, experiments were con- 

 ducted during the summers of 1910 and 1911. In 1910 24 pigs averaging 92 

 lbs. each were fed for 62 days rations consisting of about 2J lbs. of milk for 

 every pound of shelled corn. An equal number of pigs averaging 93 lbs. each 

 were fed 62 days in 1911, about 3 lbs. of milk for every pound of shelled corn. 

 Each year a lot was fed on shelled corn without milk as a check lot. All pigs 

 had an abundance of blue grass pasture. The pigs consisted of pure bred 

 Poland-Chinas. Du roc- Jerseys, Berkshires, and Hampshires, and grade Duroc- 

 Jerseys. Averaging both experiments, the lot fed shelled corn made a daily 

 gain of 1.04 lbs. each, and consumed 4.6S lbs. corn i^er pound of gain. Those 

 fed shelled corn and sweet skim milk gained 1.65 lbs. each daily, requiring 3.12 

 lbs. of grain and S.59 lbs. of milk per pound of gain. The lots on corn and 

 sour skim milk gained 1.64 lbs. each daily, I'equii'ing 3.18 lbs. grain and 8.72 

 lbs. milk per pound of gain. The corn and buttermilk lots made a gain of 1.66 

 lbs. each daily, requiring 3.15 lbs. grain and 8.64 lbs. milk per pound of gain. 



Another experiment was conducted to determine the practical value of the 

 " hog motor " for fattening pigs. The hog motor is a machine with a pair of 

 burrs so constructed that the pig is compelled to grind the grain before he 

 receives it. In 1911 8 pigs, averaging a little over 200 lbs. each, were divided 

 into 2 lots of 4 each and placed in yards with access to a good rape pasture. 

 In one lot was placed the hog motor filled with shelled corn and in the other 

 lot was placed a self-feeder filled with corn meal. The test lasted 61 days.
