472 EXPERIMENT STATION RECORD. 



contained 2.18 per cent of ether extract, 2.30-t per cent of total nitro- 

 gen, and 0.296 per cent of nitrogen not digested by pepsin and trypsin. 

 After storage the amount of ether extract was 2.03 per cent, total 

 nitrogen 2.296 per cent, and nitrogen not digested by pepsin and 

 trypsin 0.388 per cent. When treated with pepsin only, 0.472 per 

 cent was not digested. A second series of analyses of 24 samples 

 showed that on an average the nitrogen content was 2.409 per cent 

 before storage and 2.4 after storage. The author's general deduction 

 was that under the experimental conditions the nitrogen content of 

 the feeding stufts remained practically constant, while the digestibilit}^ 

 of these constituents decreased somewhat. The percentage of ether 

 extract pi'esent changed somewhat, but not regularly. — f. w. woll. 



Analyses of commercial feeding stuffs, J. L. Hills, C. H. Jones, 

 and B. O. ^Y iiiTii {Vermont Sta. Bui. 78, pp. 165-186, fig. i).— The 

 commercial feeding stuffs collected in the fall of 1899 and anal3"zed in 

 compliance with the State law regulating the sale of such materials, 

 including 265 samples of cotton-seed meals, linseed-oil meals, gluten 

 meals, gluten feeds, oat feeds, corn-and-oat feeds, provenders and 

 similar products, wheat feed, poultry feeds, and animal meals. 



"No cases of adulteration were found among the cotton seed, linseed, or gluten 

 products, although certain brands do not grade as high as others and are open to 

 improvement. There seems decided tendencies toward greater uniformity of quality 

 with several brands. Many brands of oat feeds, dairy feeds, corn-and-oat feeds, 

 provenders, and the like were found to contain a large quantity of oat hulls, more 

 than they should carry were the goods made from 'pure grains ground together.' 

 Such feeds are of inferior quality, and their purchase is of very doubtful advisability. 

 The more highly concentrated feeds cost more, but for the purpose for which such 

 materials are generally bought — to furnish protein — are much less expensive than 

 low-grade goods." 



For purposes of comparison, an average table is given, showing the 

 average composition of the commercial feeding stuffs sold in New 

 England markets, 1898-1900. 



Skim-milk calves, H. M. Cottrell, D. H. Otis, and J. G. Haney 

 {Kani>as Sta. Bui. 97, pp. 117-132, figs. 7). — The possibility of raising 

 calves on skim milk suitably supplemented by other foods is discussed 

 and a test with 13 calves (9 heifers and 4 steers) from scrub cows 

 reported. Four or five da3^s after birth the calves were taken from 

 the cows. Skim milk was then gradually substituted for whole milk. 

 The amount fed was in(U'eased, and finally reached 22 to 24 lbs. per 

 head per day. In addition to skim milk, 4 of the calves were fed 

 flaxseed made into a jelly with hot water and 4 were fed Blatch- 

 ford's calf meal mixed with water to form a gruel. Some dry Kafir 

 corn meal was also fed ]K)th lots. The remaindtM' of the calv(\s included 

 in the test received dry Kafir corn meal in addition to skim milk. As 

 the test progressed, corn meal was sometimes substituted for Kafir 

 corn meal Avith all the calves. The heifer calves were given some
