lowest in nitrogen from the East, and the medium grades from the central cotton- 

 growing region. 



"There is very possibly a relation between the rainfall and the nitrogen content 

 of cotton seed, the seed being richer in more arid sections. This difference may, 

 however, be due to other causes."

 bread. 



A summary of recent American work on feeding stuffs, C. F. Langworthy 

 ( U. S. Dept. Agr., Office of Experiment Stations Rpt. 1903, pp. 513-536). — Data regard- 

 ing investigations published in the United States during the last three and a half 

 years, which have to do with the composition, digestibility, feeding value, adultera- 

 tion, and sophistication of feeding stuffs, and related topics are summarized and 

 discussed, with a view to showing the scope and extent of the work — particularly 

 that carried on at the experiment stations. 



Feeding-stuff inspection, C. D.Woods and J. M. Bartlett {Maim Sin. Bui. 102, 

 pp. 37-62). — In carrying out the provisions of the State feeding-stuff law, 668 samples 

 were analyzed, including cotton-seed meal, sugar and flaxseed meal, linseed meal, 

 old and new process, gluten meal and feed, distillers' grains, a mixed feed containing 

 distillers' grains, calf meal, molasses feed, animal meal, beef scrap, and similar prod- 

 ucts, poultry feeds, mixed and proprietary feeds, clover meal, bran, flour, and red- 

 dog flour. 



In general the feeding stuffs analyzed corresponded with the guaranteed composi- 

 tion. "The gluten feeds run considerably under the guaranteed percentage of pro- 

 tein. . . . The seasons of 1902 and 1903 were unfavorable to corn, and it. may be 

 that another season's goods may contain nearer 28 per cent protein. In compound- 

 ing rations it will, however, probably be safer to discount this guarantee somewhat." 



Commercial feeding stuffs sold in Maryland (Maryland Agr. Col. Quart., 1904, 

 No. 24, pp. 1-13). — According to the provisions of the State feeding-stuff law analyses 

 were made of a number of samples of Ajax flake, bran, corn-and-cob meal, cotton- 

 seed meal, corn oil-cake meal, dried distillers' grains, gluten feed, hominy meal. 

 linseed meal, malt sprouts, meat meal, middlings, red-dog flour, molasses feed, wheat 

 screenings, calf meal, mixed and proprietary feeds, and poultry feeds. 



Miscellaneous analyses, E. F. Ladd (North Dakota Sta. Rpt. 1903, pp. 33-35). — 

 Analyses are reported of wheat bran and shorts, stock food, prairie grasses, flax 

 shive, and a commercial cattle feed. Some of the data reported follow:

Molasses as stock feed ( Demeter, 2 (1904), N"- 8, pp. 26, 27). — The manufacture, 

 feeding value, and importance of molasses feeds is briefly discussed. According to 

 the author one of the chief requirements in molasses feeds is a satisfactory absorptive 

 material. "One of the best that has been tried is finely ground bagasse." Its 

 absorptive power is high, and "from it and molasses a food can be made that lias 70 

 per cent of digestible carbohydrates."
