490 EXPERIMENT STATION RECORD. 



Theg Is examined included wheat, bran, shorts, and middlings, cotton-seed meal, 



crushed cotton seed, corn-and-cob meal, ship stuff, Mack's mule feed, and a number 

 of commercial and mixed feeds. In a table which summarizes the composition of a 

 number «if American feeding stuffs, the author also reports analyses of heggarweed 

 hay, and wire-grass hay. The author concludes that, ''judged by the samples exam- 

 ined, a large proportion of the concentrated feeding stuffs on the Florida market is 

 of an inferior quality." 



Commercial feeding-stuff law, B. E. McLin I Via. Mo. Bui. Dept. Agr., 15 (1905), 

 No. 2, pp. 39-50). —Data are quoted regarding the composition of a number of com- 

 mon American commercial feeding stuffs, and the Florida feeding-stuff law, which 

 went into effect in August, 1905, is given. The law provides for the inspection and 

 labeling of commercial feeding stuffs, and imposes a tax of 25 cts. per ton on such 

 goods. Penalties are provided for infringement. 



Tln» State commissioner of agriculture is entrusted, with the carrying out of the 

 provisions of the feeding-stuff law. 



Commercial stock feed, E. E. Rose (Flu. Mo. Bui. Dept. Agr., 15 (1905), No. 3, 

 pp. 58-67). — Data noted from another publication (see above) are summarized 

 regarding the need of a State pure-food law, and figures are quoted showing the aver- 

 age composition of a number of common commercial feeding stuffs. 



Inspection of feeding stuffs (New York State Sta. Bui. 268, pp. 285-322) .—The 

 list of feeding stuffs licensed for sale in New York in 1905 is given and the results of 

 analyses made under the provisions of the State feeding-stuff law of a number of 

 samples of cotton-seed meal; linseed meal; gluten meal and feed; germ oil meal; corn 

 bran; dried distillers' grains; malt sprouts; dried brewers' grains; hominy feeds; 

 mixed wheat offals, i. e., mixed feeds; compounded, i. e., proprietary or commercial 

 feeds; meat meals and similar goods; mixed poultry feeds; sugar beet by-products; 

 barley feeds and meal; ground oat hulls; oat feeds; wheat breakfast food by-products; 

 alfalfa meal; rye mixed feed; buckwheat middlings; rice feed; and miscellaneous 

 mixed feeds. 



Singed cacti as a forage, J. J. Thorxber (Arizona Sta. Bui. 51, pp. 546-549, 

 pgs. 2). — Data regarding the importance of cacti as forage plants are reported, 

 together with analyses noted from another publication (E. S. R., 16, p. 1003). The 

 general conclusions follow: 



"The real value of the stems of the cholla, prickly pear, and other cacti for forage 

 is not fully determined. The consensus of opinion among feeders in Australia and 

 Texas seems to be that prickly pear maintains life, but does not fatten animals. The 

 subject is one properly to be investigated, especially in view of the interest in forage 

 cacti current at the present time." 



Animal breeding and feeding investigations, D. E. Salmon ( U. S. Dept. Agr., 

 Bur. Anim. Indus. Oirc. 77, pp. 527-538, pi. 1). — Noted from another publication 

 (E. S. R., 17, p. 169). 



The effect of lecithin on proteid metabolism when taken with and without 

 asparagin, W. Voltz (Arch. Physiol. [Ptfia/er], 107 (1905), No. 7-9, pp. 415-425). — 

 The results of an extended series of experiments which were made with dogs are 

 reported. 



The author's principal conclusions follow: With the same individual under uniform 

 diet and like conditions considerable variations occur in the nitrogen metabolism. 

 The nitrogen metabolism was increased much more when casein and asparagin were 

 fed together than was the case with albumin and asparagin. Replacing apart of the 

 albumin nitrogen by an equal quantity of lecithin nitrogen affected the protein 

 cleavage in the body favorably. Good results were also noted when lecithin and 

 asparagin replaced part of the albumin nitrogen. 



The oft-noted increase in protein metabolism when asparagin was fed with proteids 

 containing phosphorus (paranuclein, casein, or brain tissue), as compared with the
