must be given in a dry condition and only in small quantities until the animal 

 becomes accustomed to them. If any intestinal irritation results they should 

 be discontinued.

 zyms that cause the production of mustard toxin. 



The availability of phosphorus compounds in rations for ruminants, G. 

 FiNGERLiNG (BiocJiem. Ztschr., 37 {1911), No. 3-Jf, pp. 266-271). — (Jrowing lambs 

 and lactating goats were given phytin, lecithin, and other phosphorus com- 

 pounds, but there appeared to be no essential difference as to their digesti- 

 bility. Further work showed that all phosphorus compounds were better util- 

 ized in tender grass and in concentrated grains than in hay. Further work 

 along this line is promised. 



[Registered feeding stuffs] (Kansas Sta. Feeding stuffs Buls. 17-22. pp. 4 

 each). — These contain a list of manufacturers and the name of feeding stuffs

Concentrated commercial feeding stuffs. J. D. Turner and H. D. Spears 

 (Kent tick If 8ta. Bui. 156. i)p. 63-180).— This reports the results of the state 

 feed inspections, including the protein and fat content of the following feeds: 

 Alfalfa meal, beef scrap, ground bone, dried beet pulp, corn bran, corn chop, 

 crushed corn, corn meal, gluten feed, hominy meal, cotton-seed meal, linseed 

 meal, rye feed, wheat by-products, distillers' dried grains, brewers' dried grains, 

 and mixed feeds. In some cases the number of weed seeds was also deter- 

 mined. 



" The feeds in which we found the higher amount of sand were mixed feeds 

 containing finely ground materials and masked in other ways, and they were 

 found to contain various amounts of screenings, weed seeds, etc. This would 

 seem to indicate that the sand had found its way into the feed by the use of 

 sweepings and screenings, and probably not by the Intentional addition of sand. 



" The ash of the various feeds was also determined and ... it is seen that 

 those feeds containing high percentages of this constituent are those running 

 high in the amount of sand present. Whether sand or soil is added inten- 

 tionally or not, it is evident and the fact remains that such materials should 

 not be in feeding stuffs in appreciable quantities, at least."
