reeding stuffs (,Ber. Agr. Chem. KontroU u. Vers. Stat. Pflanzenkrank. Prov. 

 Sachsen, 1913, pp. 23-^0}. — ^Analyses are reported of peanut meal, coconut cake 

 and meal, linseed cake and meal, palm kernel cake and meal, rape-seed meal, 

 sesame-cake meal, sesame seed, soy-bean chop, sunflower-seed meal, molasses 

 feed, crude molasses, fresh and dried beet tops, turf molasses feed, sugar beets, 

 potatoes, potato silage, blood meal, fish meal, calcium feed, and potato flakes, 

 together with corn, wheat, oats, rice, barley, rye, and their various products. 



Cotton-seed products and their competitors in northern Europe, E. W. 

 Thompson (U. 8. Dcpt. Com., Bur. Foreign and Dom. Com., Spec. Agents Ser., 

 No. 84 {1914), pp- 93). — This bulletin reports an investigation made of the 

 commercial feeding stuffs of Germany, the United Kingdom, the Netherlands, 

 Denmark, Sweden, and Norway, with special reference to their competition with 

 American products. Methods of feeding in vogue in these countries and the 

 importance of the various cakes and meals used are discussed. The theoretical 

 valuation of feeding stuffs as determined by the Kellner, Hansson, and other 

 methods is treated. There are included lists of feeding stuffs dealers in the 

 several countries. 



Fish feed meal, M. Kling (Dent. Landw. Presse, 41 {1914), No. 37, pp. 457, 

 458). — In commenting on the variability of composition of the different brands 

 of fish meal the author recommends a uniform grade, having a guarantied 

 analysis of 50 per cent protein, 5 per cent fat, 5 per cent salt, and from 20 to 

 25 per cent calcium phosphate. 



Bengal beans, a new fodder, H. S. Sheewsbuby {Bid. Dept. Agr. Trinidad 

 and Tobago, 13 {1914), No. 81, pp. 194, 195). — Exi>eriments with Bengal beans, 

 presumably Macuna utilis, indicate that very little, if any, hydrocyanic acid or 

 other toxic materials are present. The taste and odor of the whole meal from 

 the beans are pleasant and closely resemble those of pea meal. It is shown that 

 these beans are somewhat superior in feeding value to French, Lima, or Java 

 beans and that like these beans their nutritive properties are principally due 

 to the high content of carbohydrates and proteins. Owing chiefly to their low 

 percentages of fat, their value is considerably less than that of soy beans. 

 Caution is recommended in the use of these beans as fodder. 



The phosphoric substance of prairie grass, C. Dusserre {Bui. Soc. Vaud. 

 Sci. Nat., 5. scr., 49 {1913), No. 181, pp. XL~XLII).— It is shown that the 

 principal phosphorus compounds found in prairie grass which are of nutritive 

 value to animals are the lecithins, the phytins, and the nucleins. Of these the 

 phytins are in greatest amount. 54 to 62 per cent ; the nucleins, 30 to 40 per 

 cent; and the lecithins, about 10 per cent. 



It was found that the application of superphosphate materially increased 

 the phosphorus content of the plant and that this in turn increased the value 

 for feeding purposes. 



Mineral requirements of farm animals {Wisconsin Sta. Bui. 240 {1914), 

 pp. 32, 33). — "A dry pregnant milch goat was fed rations low in lime during 

 the entire gestation period, at the end of which she gave birth to twin 5-lb. 

 kids, of normal weight and vigor. During this single period of gestation, the 

 goat lost about 20 per cent of the total amount of lime contained in her body, 

 including the amount stored in the bodies of the offspring, although without 

 any outward or apparent ill effects." It is estimated that for fetus building 

 and for milk production the 1,000-lb. pregnant cow will require from 1.8 to 2.1 

 oz. of lime per day. Such requirements are usually met by the ordinary farm 

 roughages such as hay and corn stover, but with straw in any large quantity 

 as a part of the ration the lime supply would be deficient. 



Value of fat from various sources {Wisconsin Sta. Biil. 24O {1914), PP- 33, 

 34). — In studies by E. V. McCollum continuing previous work (E. S. R., 28,
