Methods -of poultry management at the Maine Agricultural Experiment 

 Station, K. Pkarl (U. S. Dept. Agr., Farmers' Bui. 357, pp. 39, fly. 10). — The 

 information in this publication has been compiled chiefly from Bulletin 90 of 

 the Bureau of Animal Industry of this Department (E. S. II., IS, p. 471) and 

 from various bulletins of the Maine Station. The principal topics treated are 

 the selection of breeding stock, raising chickens by natural and artificial 

 processes, feeding chickens on the range and the cockerels for market, housing 

 and feeding the hens, the yards, a poultry house disinfectant, and trap nests. 

 A portable brooder house, a chicken feeding trough, a trap nest, and two types 

 of curtain-front houses are figured and described. 



Methods of keeping pedigree records in use at the Bhode Island Agricul- 

 tural Experiment Station, L. J. Cole {Rhode Island Sta. Rpt. I'JOS, pp. 311- 

 S2Ji). — The method of keeping pedigree records used in the poultry experi- 

 ments at this station for the past few years is described. It is a modification 

 of the method used by (4alton for keeping human pedigree records. 



Breeding work with pigeons, L. J. Cole (Rhode Island Sta. Rpt. 1908, pp. 

 299-302). — This is a preliminary report on the inheritance of color in Tumbler 

 pigeons. When red Tuml>lers and black Tumblers are mated black appears to 

 be dominant and red recessive. The birds of the first generation are all black 

 but with reddish tips that may be lost in later molts. 



Naturalizing the ostrich, W. Robinson (Amer. Rev. of Reviews, 39 (1909), 

 No. 5, pp. rj61-')G6, fl(/s. 9 ) . — This is a popular article on the ostrich industry. 



Commercial feeding stuffs, J. L. Hills, C. H. Jones, and C. L. Beach (Ver- 

 mont Sta. Bui. 13S, pp. 3-10). — Analyses are reported of cotton-seed, linseed, 

 and alfalfa meals, gluten, flax, molasses, oat and hominy feeds, distillers' and 

 brewers' grains, and poultry and miscellaneous feeds. 



Licensed commercial feeding stuffs, 1908, F. W. Woll ( Wisconsin Sta. Bui. 

 110, pp. 3-96). — A total of 521 samples of licensed and GO samples of unlicensed 

 brands of feeding stuffs were analyzed during the past year under the State 

 feeding stuff law, against 257 samples in 1907, an increase of 129 per cent. 



The feeding stuffs analyzed included oil and cotton-seed meals, distillers' 

 grains, gluten and hominy feeds, wheat bran, and middlings, red dog flour, rye, 

 barley, buckwheat and mixed feeds, dried brewers' grains, malt sprouts, and 

 poultry and miscellaneous feeds. The bulletin contains also a list of licensed 

 manufacturers and dealers in proprietary feeding stuffs, the text of the feeding 

 stuffs law in operation, and a discussion of violations thereunder. 



On the digestibility of the different sorts of irrigated hay compared with 

 meadow hay in the same district, K. Friedlaender (Landw. Vers. Stat., 69 

 (1!)0S), Ao, 3-1/, pp. 2.'i5-258). — In this digestion experiment with 2 wethers it 

 was found that in all cases the irrigated hays had a higher protein digestion co- 

 efficient than had ordinary meadow hay. The reverse was true of the fat and 

 carbohydrate coefficients. 



A ration problem discussed, G. Miyawaki (Hoard's Dairyman, .'/O (1909), 

 Ao. 10, pp. 3'i0-3.'i2, dyms. 6). — In this article the author gives illustrations of
