condition by proper niotliods of bousing and feeding, and (c) paying attention to 

 the actual breeding ability (as sliown by batching performance) of the stock 

 and the exercise of selective breeding to improve this character." 



An annotated bibliography of the literature is apjiended. 



An act to regulate the sale of concentrated commercial feed stuffs { Massa- 

 chusetts Sta. Circ. 11, pp. }). — This contains the text of the feeding stuffs law 

 and interpretations of the law. 



The role of the ash constituents of wheat bran in the metabolism of her- 

 bivora, E. B. Hart, E. V. McCollum. and (i. C. Humphrey {Wisconsin Sta. 

 Research Bui. 5, pp. 173-188). — Previously noted from another source (E. S. R., 

 21, p. 3GG). 



Further contributions on the composition of hay from sewage meadows, 

 P. Ehrenberg (Landw. Vers. Stat., 11 (190!)), No. .',-J, pp. 263-286).— A con- 

 tinuation of work previously noted (E. S. R., 20, p. 172). Analyses reported 

 show that hay from sewage meadows contains larger percentages of protein, albu- 

 min, fat, and ash but less fiber than bay from natural meadows. Analyses are 

 also given of clover grown on sewage meadows and of silage made from sew- 

 age hay. 



Acidifying silage beet chips by means of lactic acid cultures {Amcr. Sugar 

 Indus, and Beet Sugar (ia.~.. 12 ilDlO), No. 2, p. 3'J). — This is a report of a 

 successful experiment in which beet chips as they came from the diftusiou 

 battery were inoculated with a pure culture of lactic-acid bacteria. At the end 

 of G months the chips had an aromatic odor of fresh distillery chips. The 

 effect of the inoculation was not sutiicient to give a pure lactic fermentation 

 but was .such as to restrict the activity of the decomposition organism. Direc- 

 tions for preparing the liquid for s])rinkling the chips are given. 



Experiments in feeding these chips to steers with favorable results are also 

 reported. 



The utilization of pea-cannery refuse for forage, M. A. Crosby ([/. S. Dept. 

 Agr., Bur. Plant Indus. Circ. //J, pp. 12, figs. 3). — This bulletin describes meth- 

 ods of using refuse pea vines as green feed, silage, hay, and fertilizer. Results 

 from practical men are cited which show that pea vine silage is about equal in 

 feeding value to corn silage for dairy cows, beef cattle, and sheep. Pea vine 

 hay is considered equal or superior to clover hay for all classes of farm stock. 

 The use of the vines as a soiling crop is necessarily limited to the immediate 

 vicinity of the canning factory. As a manure pea vines have a fertilizing value 

 of about $2.G0 per ton. 



Concerning the feeding of straw, E. Pott {IUus. Landw. Ztg., 29 (1909), 

 No. 101, pp. 921-929). — A summary and discussion of methods of cutting, shred- 

 ding, steaming, softening, and mixing with molasses, and of other practices for 

 utilizing straw and coarse fodders as feeding stuffs for cattle is given. 



Rearing calves on skim milk and supplementary feed, H. W. Norton, Jr. 

 (Michigan Sta. Bui. 231, pp. 3-29, figs. 10). — This bulletin contains information 

 on stabling and methods of feeding calves and gives records of G."] pail-fed calves 

 v.hich include grade and pure bred stock of both beef and dairy types. The 

 feeds consisted of whole milk, skim milk, silage, hay, oats, green feed, beet 

 pulp, and grain. Whole milk was valued at $1 per 100 lbs., and skim milk at 20 

 cts. The whole milk was usually fed for 5 or G weeks, with the exception of the 

 last lot, in which it was continued for 12 or 13 weeks. In some cases the skim 

 milk feeding continued for 1 year. The year was divided into 4 ecpial periods 

 of 13 weeks each. As a rule the greatest gains were made during the second 

 period and at the least cost.
