under pressure to dissolve incnistlng substances and the composition and nutri- 

 tive value of the resulting material were studied. 



According to the author, the total ash content was increased by this ti-eat- 

 ment, while the percentage of silica was diminished. Marked changes were 

 noted in the pentosans, ligniu, and cellulose of the crude fiber, acetic and other 

 acids being eventually formed from pentosans and some glucose from the cellu- 

 lose. Experiments with sheep showed that the digestibility of the crude fiber 

 and ash constituents was materially increased. The straw freed from incrust- 

 ing substances was readily eaten. 



Straw with incrusting' substance removed as a feed for farm animals, P. 

 DiFFLOTH {Jour. Agr. Prat., u. svr.. 1 '/ U'>07). ^'o. 31. pp. J'iS-1'fO). — A sum- 

 mary of data showing the increased value as a feeding stuff of straw from 

 which the incrusting substance has been removed. 



Feeding experiments at Pentkowo Experimental Farm, M. Gerlach {Ber. 

 Vcrsuchsg. Pentkowo, .'/ {lf)0.'t-5), pp. J7--'/6'; ub-s. in Zcnthl. Ayr. Chem., 36 

 (1907), jVo. 7, pp. 465-Jf~0y. — In feeding experiments reported with steers, dried 

 sugar-beet leaves gave somewhat better results than soured beet leaves, and 

 dried beet chips and molasses better results than sugar-beet chips. 



In tests with pigs, potato flakes were readily eaten and were nearly as sat- 

 isfactory as steamed potatoes. 



When meat meal, iieanut cake, corn, and molasses were compared as tlie prin- 

 cipal feeding stuffs in rations with pigs, the best results, as regards gains in 

 weight and quality of flesh, were obtained with corn supplementing potatoes 

 and skim milk. The least satisfactory results were obtained with the rations 

 in which molasses was fed. 



The composition and digestibility of sugar-beet chips and their value as 

 a feeding stuff, F. IIokcamp (JAindic. Vers, titat., 63 {11)01), Ao. 5-6', pp. 381- 

 Ji06). — In a study of the feeding value of sugar-beet chips digestion experi- 

 ments were made witli sheei>. whicli gave the following average coefficients: 

 Dry matter 86, organic matter 88, protein (!0, nitrogen-free extract !»4.5, and 

 crude fiber 70 per cent. 



Fi'om his inve.stigation the author concludes that sugar-beet chips are a satis- 

 factory feeding stuff but that too great reliance must not be placed on this 

 material. 



Composition and digestibility of beet chips, F. Honcamp (Lundic. Vers. 

 Stat.. 66 {11)01). A'o. 3. p. 256). — An explanatory note regarding investigations 

 cited above. 



Molasses feeding. I.. Kuntze (BI. Zuckcrriibcnhaii, I'f (lUOl), \o. 10, pp. 300- 

 SOJf). — A summary of statistical and other data regarding the value of molasses 

 as a feeding stuff for farm animals. 



Sugar in the feeding of farm anim.als (Bui. Ecolc Prat. Agr. Bcrthonvul, 

 1906, pp. 'f-32, dgms. ^). — In tests with horses 1.5 to 2 kg. of denatured sugar, 

 i. e., sugar to which oil cake has been added, gave satisfactory results as re- 

 gards maintenance of weight and did not cause digestive disturbances. Satis- 

 factory results were also obtained when denatured sugar was fed to milch 

 cows, pigs, and calves. The author concludes, therefore, that this material, 

 which possesses a pleasing odor and flavor, is a satisfactory feeding stuff and 

 that 1 to 3 kg. per head per day may be fed to horses, 1 to 4 kg. to cattle, and 

 300 to 500 gm. to sheep and pigs.

 Consular and Trade Rpts. [U. 8.], 1901, ISfo. 325, p. J 68). —According to the 

 data summarized, the algeroba bean is fed with satisfactory results to horses 

 in southern Spain. " In feeding the beans are broken into halves or quarters
