liay WHS cut very young, probably because of the low solubility of the phosphoric 

 acid and to the presence of silicic acid which has a toxic effect. 



The results of the digestibility triiils are shown in the following table:

[Silage making and feeding], H. E. Dvorachek (Colorado Sta. Bui. 200 

 (1914), PP- 22-32, fig. 1). — An account of methods of ensiling corn, sorghum, 

 Kafir corn, alfalfa, peas, small grains," Ilussian thistle, beet tops, beet pulp, and 

 cured fodder, and the feeding of these to farm animals. 



On the nutritive value of potato distillery refuse and other waste mate- 

 rial (Landir. JaJtrh.. J,', (1913), Xo. J, pp. GSl-S.'i'i. pis. J,, fig. 1). — I. Introduc- 

 tion, W. Vultz nud N. Zuntz (pp. GS1-GS4). — Commenting on the value of the 

 waste material from the potato distillery plants it is stated that in general the 

 feeding value of the refuse depends upon the quality of the material, and upon 

 its actual content of potato, malt, and yeast.- 



II. On the specific value of the feed materials, W. Yoltz. J. Paechtaer. and 

 A. Baudrexel (pp. 685-764). — Experiments conducted in 1S5G on the feeding of 

 potato refuse in various proportions with grain to dairy cattle are cited. The 

 organic matter in the dried refuse is given as 79.35 per cent, protein 23.81, fat 

 0.66, fiber 6.82, and nitrogen-free extract 48.06 per cent: in dried waste ma- 

 terial, consisting of potato, malt and yeast, 87.83, 7.19, 0.22. 154, and 78.88 per 

 cent, respectively.
