therein was obtained largely from Missouri lujuitry raisers and from investi- 

 gators at a number of the experiment stations. 



A colony house. A trapnest, J. Dryden and A. G. Lunn (Oregon Sta. Circ. 

 -}, PP- 7, figs. 2, dgm, 1). — This circular briefly discusses the advantages of the 

 colony system of keeping fowls. Details are given for the construction of a 

 colony house 7 by 12 ft. A house of this size will accommodate 30 to 40 fov/ls 

 and it can l)e easily moved. Directions are also given for making the trapnest 

 now i 1 use at the station. 



Frog- industry in France, F. H. Mason and H. L. Washington {DaUij Cons. 

 and Trade Rpts. [U.'S.], 1909, No. S-^J/G, pp. 1-7). — These consular reports from 

 different cities of France describe methods of propagation, catching, packing, 

 transporting, and marketing the edible frog. 



DAIRY FARMING— DAIRYING. 



A chemical and physical stvidy of the larg'e and small fat g'lobules in 

 cows' milk, R. H. Shaw and C. H. Eckles (U. 8. Dept. Agr., Bur. Anim. Indus. 

 Hill. Ill, pp. 16, Jigs. 2). — This is a preliminary report on the influence of vari- 

 ous factors upon the chemical composition of milk, undertaken at the Missouri 

 Station in cooperation with the Dairy Division of this Department. Samples 

 of milk were taken from Jerseys, Holstein-Friesian, Ayrshire, and Shorthorn 

 cattle. The large globules were separated from the small globules as far as 

 possible by the gravity process and by running through a separator. The daily 

 yield, percentage of fat, and iiercentage of globules of different sizes are given. 

 The color, specific gravity, melting point, refractive index, sajjonification, iodiu, 

 lieichcnt-Meissl. aiid Kehner values were determined, but no appreciable differ- 

 ences were found between the large and small globules. 



Oh the modifications of milk g'lobules, G. Alessi and E. Carapelle (Gior. 

 i^ci. Nat. ed Econ. [Palermo], 26 (1908), pp. 137-155, pis. 2).— Studies are re- 

 ported of the morphological alterations of the fat globules of the milk from 

 goats, guinea pigs, dogs, and Imman beings under pathological conditions. 



The composition of the milk of the dairy cow and buffalo in the Malay 

 Peninsula, B. J. Eaton (Agr. Bui. Straits and Fed. Malay States, 8 {1909), 

 So. I, pp. 15-22). — The amount of fat in the samples of milk from 25 native 

 cows varied from 1..5 to 4 per cent. The average was 4 per cent of fat and 

 9.03 per cent solids-uot-fat. The composition of milk from 2.5 buffalo cows 

 averaged 6.8 per cent fat and 10.09 per cent solids-not-fat. " Buffalo milk is of 

 a bluish-white color and the fat obtained from this milk is white and produces 

 a white butter, and yet many samples contained as much as 8 or 9 per cent 

 of fat." 



Annual report of the Kirkee civil dairy, 1907—8, J. B. Knight {Dept. Agr. 

 Boinhay. Ann. Rpt. Kirkee Civ. Dairy, 1907-8, pp. 13). — This report contains the 

 individual records of a herd which consists of 54 cows and 50 buffaloes. The 

 average yearly yield of the cows was 1,844 lbs., and of the buffaloes 1,886 lbs. 

 of milk. 



The enzyms of cow's milk, J. W. England (Amer. Jour. I'harm., 81 (1909), 

 Xo. J/, pp. 117-1 St }. — This is a resume of some recent work on this subject. 



Lactic fermentation in milk, M. W. Beijerinck (Arcli. Neerland Sci. Exact, 

 et Nat., 2. scr., 12 (1908), No. 3-.',, pp. 356-378; ahs. in Bui. Insti Pasteur, 6 

 (1908), No. 20, p. 912; Jour. Roy. Micros. Soc. [London], 1908, No. 5, p. 636).— 

 Tlie author divides the lactic-acid bacteria into classes according to the 

 temperature which is most favoral)lo for their growth. Tliose in which the 

 optimum growth takes place between 5 and 20° C. constitute the cryoflora.
