turf-molasses feed, both unneiitralizod and with the acidity of the turf, which 

 is due to the presence of humic acid, neutralized with sodium hydroxid. 



It was found that the neutralized feed is as digestible, as palatable, and of 

 better keeping quality than the nonneutralized. In a warm, damp room the 

 nonneutralized feed underwent a chemical and physical change, becoming 

 moldy and taking .on a distinct aged smell. This was not the case with the 

 neutralized feed material and under dry, cool conditions it retained its quality 

 indefinitely. 



Sphagnum turf was found to be most digestible when fed in small allow- 

 ances, and the feeding of an increasing quanity of the turf lowered the digesti- 

 bility of the other materials fed with it. The energy content of the digestible 

 portion of the turf was relatively higher than that of the indigestible portion. 

 Each animal was found to possess an individual degree of digestibility for 

 turf. 



A study of the digestibility of the refuse from sulphite-cellulose manufactur- 

 ing showed that the nutrients of this feed are relatively unavailable and that 

 it decreased the digestibility of other materials fed in conjunction with it. 



Caracul sheep, T, R. GABcfA (Bol. Min. Agr. [Buenos Aires^, 14 {1912), 

 No. 10, pp. llJf5-1178, figs. 23). — An account of the history, utility value, body 

 characteristics, and introduction into Argentina of this breed of sheep. The 

 adaptability of the caracul sheep to Argentine conditions is pointed out and 

 its exploitation advocated. It is thought that tlie introduction of this breed will 

 mean a new era in the history of sheep production in that country. 



Notes on the camel, B. Danou (Bui. Off. Gouvt. G6n. Alg^rie, No. 23, Sup. 

 {1913), pp. I.'f5-157). — An account of the breeds and types of camels of Algeria, 

 their care and management, and the diseases to which they are subject The 

 production of camel hair as a commercial product is also discussed. 



Hog feeding, G. C. Wheeler, T. R. H. Weight, et al. {Kansas Sta. Bui. 

 192 {1913), pp. 3oo-Ji27, figs. 8). — Summarzing the results of experiments con- 

 ducted during 1904-1911 to determine the value of corn alone and with various 

 supplements as fattening rations for hogs the following table is given : 



Averages of various tests of supplements to corn meal for hogs. 



It is estimated that with pork at 6 cts. per pound the value returned per 

 bushel for corn in tests where com alone was fed averaged 53.6 cts. ; where 

 corn and alfalfa meal were fed 57.6 cts. ; com and meat meal or tankage 65 

 cts. ; and corn, shorts, and tankage or meat meal 69.8 cts. These experiments 

 indicate the increased value of corn for pork production from the use of highly 

 nitrogenous supplementary feeds. 



In an experiment comparing the economy of gains between large and medium 

 type Poland China hogs, the former made the most economical gains, while the 

 latter finished more quickly and carried a finish that would com>mand a higher 

 price on the market. In another experiment it was found that if corn is taken
