Fodder crops of the Punjab, J. M. DoriE ([1912], pp. II-\-31-\-VIT, pis. 

 2). — This describes methods of feeding catlle and discusses the food value of 

 native and introduced plants used as fodder for live stock. 



Statistical investigations into the utilization of fodder crops and capi- 

 tal by means of live stock in various districts in Germany, F. Waterstradt 

 (Arch. Exakte Wirtschaftsforsch., 4 (1912), iSiO. 1, pp. 88-128; ahs. in Internat. 

 Inst. Agr. [Rome], Bui. Bur. Agr. Intel, and Plant Diseases, 3 (1912), No. 6, 

 pp. 1412-1418). — This is a study of 443 farms, in which the results are arranged 

 according to the Thiinen system in the order of progressive decrease of the 

 income derived from cattle and other domestic animals, in order to determine 

 by such means their relation to the total receipts of the farm and the factors 

 of production. 



From the results, which are prepared in tabular form, there seems to be a 

 correlation between the income produced by cattle and the net and gross income 

 of the farm. Because of this it is urged that more live stock be kept, provided 

 that the area under fodder crops is intensively cultivated so that the factors 

 of production can be utilized to their fullest extent. 



Handbook on grain and feeding stuff drying, D. Meyer (Handbuch der 

 Futtermlttel und Getreidetrocknung. Leipsic, 1912, pp. XII-\-294, pis. 5, figs. 

 111). — This describes the process, machinery, and other equipment required for 

 drying grain, grass, clover, serradella, lupines, acorns, horse chestnuts, brewers' 

 grains, yeast, distillery slop, and refuse from products of starch factories. The 

 composition, digestibility, and other matters relating to the value of these 

 materials as feeding stuffs are discussed. 



Silage from turnip leaves, O. T. B janes (Norsk LandmandsUad, 31 (1912), 

 No. 34, pp. 451, 452, figs. 2). — Turnip-leaf silage, according to the author's ex- 

 perience, makes an excellent dairy feed when fed about 20 to 25 lbs. daily in 

 connection with dry roughage and grain feeds. In order to obtain a good 

 quality of silage it is important to ensile the leaves as soon as possible after 

 the cutting, while they are still green and succulent. A small stack silo is 

 described for making silage. 



Feeding stuff inspection (Maine Sta. Off. Insp. 38, pp. 25-72). — Analyses 

 are reported of cotton-seed meal, cotton-seed feed, gluten feed, linseed meal,
