 of the locusts were also determined, the averajje ])hospli<»ric acid content being 

 1.48 per cent. 



As pointed out. the dried locusts i-esemble some of Ibc commercial feeding 

 stuffs of animal origin and their use is recommended for farm animals. As 

 shown liy the results of practical (>xp(>rience, the.v have lieen particnlarly useful 

 as a poultry feed and a pig feed. Many farmers believe that locust meal jiro- 

 duces large yolks of a richer color than usual and that they do not aff(>ct the 

 tlavor of eggs. Furthermore, locusts are "well worth collecting and killing for 

 manurial purposes. Their value* as a fertilizer is very great, because of their 

 richness in nitrogen and phosphoric acid."' 



Farm animals, K. V. Wilcox {Xcw York: Doiihlcdaij, I'tujc d- Vo.. IHOG. 

 pp. 17 4- .;.77. jilx. a.i). — The characteristics of different breeds, the ])rincipal 

 Iirohlems which must be met in the feeding and care of farm animals, the im- 

 portance of different feeding stuffs, animal diseases and their treatment, and 

 other (juestions regarding tlie production, feeding, care, and management of 

 farm animals are considered in this volume, which constitutes an inii)ortant 

 summary of available data. Notable features of the volume are the extensive 

 use which has been made of the results obtained by experiment station in- 

 vestigators, and the scope and accuracy of the data presented. Special chapters 

 are devoted to the horse, nuile. beef cattle, dair.v cows. i)igs. sheep, goats, and 

 jioultry. 



Steer feeding, J. II. Skinner and W. A. Cochel (Indiana Sta. Bui. 11'), pp. 

 311-337, figs. 6). — Using 3 lots of 11 steers each the efficiency of various combi- 

 nations of corn and other feeds, such as corn stover, oat straw, and clover bay, 

 commonly available mi Indiana farms, was stndied. 



On ear corn and clover hay. the average daily gain per steer in the 180 days 

 of the test was 2.08 lbs. On ear corn, shredded corn stover, oat straw, and a 

 little linseed meal, the gain was 1.78 lbs. per head ])er day, and on a similar 

 ration without linseed meal the gain was l..'iO lbs., the cost of :\ i)ound of gain 

 in the ."> cases being (!..")!). 7.70. and 8.46 cts. The smallest grain ration. 17.r.0 

 lbs. was fed to the lot receivin.g ear corn, shredded stover, and oat straw, and 

 the largest grain ration. 20.45 lbs., to the lot given the linseed meal. The 

 last mentioned lot received the smallest amount of coarse fodder. 7.02 lbs., and 

 tlie lot fed clover hay the largest amount, 8..",2 lbs. 



I'igs sutlicient in munber to gather the undigested feed followed the steers 

 and produced 2.10 lbs. of pork per bushel of corn on the clover-hay ration, 

 1.80 lbs. on the ration containing linseed meal, and 1.7S II>s. on th(> ear corn, 

 shredded stover, and oat straw ration. 



Some of the conclusions drawn were in effect as follows: The ear corn, 

 shredded stover, and oat straw ration was neither etticient. economical, nor 

 profitable. The addition of a nitrogenous feeding stuff, either in the form of a 

 concentr.-ited feed or coarse fodder, added to the efficiency of the ration and the 

 [irotit of the feeder. The concentrated feeds tested, namely, clover ha.v and lin-
