Feeding- of poultry, C. K. J. Walkey (Jtiar. Bd. Agr. [Loh'Ioh], 10 {i:>OS), Xo. 

 S, }>i>. 3o6-o69, Jiys. --*). — The feeding and care of chickens, dncky, geese, and turkeys 

 are tliscussed; rations are suggested; directions for making poultry houses are given, 

 and otlier related topics arc spoken of. 



Poultry fattening by trough and machine [if ark Lane Express, 88 (190-3), 

 No. 3748, p. 70). — Four tests, each with 44 chickens and covering al)ont 3 weeks, 

 were made at the Agricultural and Horticultural Training Farm at Uckfield. The 

 chickens were fed from troughs and later with a cramming machine, receiving a 

 mixture of skim milk, ground oats, and fat in different proportions. The best results 

 were obtained when 8 lbs. of ground oats and 1 11). of fat were fed per gallon of 

 skim milk. 



Fattening fowls in Ireland [M<n-k Lane EApres.^, 88 {190S), No. 37i^4, p- HI).— 

 In a test made 1)y the Windgaji Cooperative Poultry Society, County Kilkenny, 28 

 fowls, divided into lots of 7, and fed in coops for 10 days on maize meal and pollard 

 4:3, wet with separator skim milk, gained nearly 1 Il>. each. The total profit was 

 calculated to be $3.54. 



Breeding geese for "foie gras" {Mark Ljme Express, 88 {19U8), Xu. S76^, 

 l>. 48.'). — The fattening of geese for the i)roduction of large livers for use in making 

 "foie gras" is briefly des.cril)ed. During the fattening period, which lasts from 4 to 

 5 or possibly 6 weeks, the birds are kept in close cages and are fed 2 or 3 times a day, 

 by cramming, a daily ration consisting of 1.5 lbs. maize meal and beans cooked in 

 water, the amount being increased as the appetite grows. The geese are supplied 

 with fresh water to which a little wood charcoal is sometimes added. 



The effect on hens' eggs of the rays emitted by radium, (i. Schw.vkz (Arrh. 

 rin/.^lol. [I't1i'n/fr], 100 (1003), Xn. 9-10, pp. .'>3..!-o4'', Jiil^- 5 ). — Two-hundredths gram 

 of radium bromid inclosed in a brass box was placed on the shell of an egg. In the 

 V)ottom of the box there was an ojiening covered by a plate of mica which permitted 

 the passage of the Becquerel rays. In one of the tests the operation was carried out 

 in an atmosphere of hydrogen. 



From the results of all the tests it ajjpeared that the rays induced a number of 

 marked changes. Where they acted upon the shell a light-gray color was noticeable. 

 The meml)rane lining the egg was unaffected, but the white was thickened and a sort 

 of skin formed in it. A luminous light-gray ])atch al)Out 5 nun. in diameter was 

 observed in the yolk. This i)atch was somewliat harder than the surrounding por- 

 tion. The flavor was changed. 



The author concludes that the Becquerel rays induce changes in albumenoid 

 bodies similar to those produced by dry distillation, but do not cause extensive 

 changes in native proteids. They remove the color from the organic x>igment lutein. 

 Furthermore, these rays exercise a marked effect upon lecithin in cell substances. 

 This fact, it is believed, explains their l)iological effect, and especially their effect 

 ui)on rapidly growing normal an<l pathological tissue. 



Pheasants, Q. L. Darlixhtox (Boston: ILiib Poultry and , Supply Co., 1902, pp. 48, 

 jils. 4, fiy. 1). — On tlie basis of personal experience, the author gives directions for 

 i lousing, breeding, feeding, care, and management of Asiatic pheasants, quail, 

 prairie chickens, and partridges or ruffeil grouse. In the author's opinion all these 

 birds may be successfully and profitably raised in captivity.
