of the plauts was the same with these artificial cultures of fecal bacteria as 

 in the feeding experiments. Those of the corn plant were less resistant than 

 those of the oat, and those of the oat less resistant than those of the wheat. 



Experiments in pig feeding, T. I. Mairs and S. W. Doty {Pennsylvania 

 i?ta. Bui. D-j, i)i>. 3-16, figs. 6). — Middlings and a mixture of corn chop and 

 tankage were compared as feeds for growing and fattening pigs. 



Six pur(>-l)red Chesliires 14 weeks old were used for the experiments, which 

 lasted 17 weeks. Lot 1, which received a ration of middlings, made an 

 average daily gain per head of 0.945 lb. at a cost of 7.4 cts. per pound. For 

 lot 2, fed corn chop and tankage 3 : 1, the corresponding values were 1.257 lbs. 

 and 7.3 cts. per pound. In the slaughter tests the lots dressed respectively 

 78.4 per cent and 81.7 per cent of the live weight. The feeds were rated as 

 follows: Middlings $30. corn chop $34, and tankage $28 per ton. 



" Pigs on a ration of middlings alone made better use of their feed at first 

 than those on a ration of corn chop and tankage, but later the exact reverse 

 was the case. The pigs on the exclusive middlings ration were not as active 

 and healthy as those on cDru chop and tankage, neither did the former eat 

 with the same relish. . . . Neither ration provetl very profitable for gi-ow- 

 ing and fattening pigs. The corn chop and tankage had a slight advantage in 

 cost per pound of gain."

Sustaining horses in long-distance travel, L. Oculvy [Breeder's Guz., .56 

 {1909), A'o. 21i, PI). 1292-129.'t). — An account of the methods of feeding employed 

 in recent tests of long-distance riding. The advantages of feeding both sugar 

 and molasses are pointed out. The best mode of use for a long journey is 

 stated to be about 1 Yb. of sugar in 5 qts. of water. In some cases horses have 

 to be taught to take it in this form though they will readily eat sugar in the 

 feed. 



State horse-breeding and army remount buying in France iDept. Ayr. and 

 Tech. Instr. Ireland Jour., 10 {1909), No. 1, /*/>. 'i3-i)9, pis. //).— An account of 

 the system of state aid to horse breeding, the chief features of which have been 

 in existence since 1665. At the present time there are 22 state studs which are 

 required by laAV to keep about 3,450 stallions of various breeds. In addition
