A FEEDING EXPERIMENT EOK MTLK, J. WiLSON. C. F. OURTISS, 



B. S. A., D. A. Kent, B. S., G. E. Patrick, M. S., and E. K 

 Eaton, B. S. (pp. 152-161). — This is a record of a sinjijle cow from 

 Fclniiaiy 25 to June 18. In the fir.st 2i mouths of this time corn 

 fodder, corn silage, sorghum sihige, and roots were compared, feeding 

 20 ])ounds of corn-and-cob meal per day with each coarse fodder; 

 from ]N[ay 10 to June 7 half the corn-and-col> meal was replaced 

 by 7 pounds of bran and 3 pounds of linseed meal, and fed with hay; 

 and from June 9 to IS this grain ration was reduced one half and fed 

 with pasturage. The data showing the amounts of food consumed 

 and of milk yielded, and the com])osition of the milk are tabulated. 

 " Tlie sulistitution of bran and oil meal for half the amount of corn 

 meal resulted in a marked increase in both quantity and qualitj' of 

 milk, the increase in quality being still more than the increase in quan- 

 tity." 



Pig-feeding experiiment, J.Wilson, C. F. Curtiss, B. S. A., 

 D. A. Kent, B. S., and G. E. Patrick, M. S. (pp. 162-105).— This is a 

 record of the food consumed and the live weight gained by a .sow and 

 her litter of seven ])igs for 15;; days. The principal food was ear corn 

 and shelled corn, supplemented at dittVrent times by grouiid barley, 

 linseed meal, corn-and-cob meal, and bran, all of which were soaked 

 l)efore feeding. The sow and pigs together gained 6265 pounds live 

 weight, and consumed 2,(U2 i)Ounds of grain during the trial. The 

 cost of the rations is not given. 



Reports on entomological work, H. Osborn, M. S., and H. A. 

 Gossard, B. S. (])1). l<i6-lS0, tig. 1). — The following summary of this 

 article is taken from the bulletin: 



The clover seed caterpillar {Grapholith^ iniersiinctana), which ha.s been abundant 

 and destructive, is described and ligured in different stages, and the conclusion 

 reached [from observations cited] that cutting the clover and storing it while the 

 caterpillars are still in the clover heads, results in the entire destruction of the insect. 



Experiments with hopper-dozers for grass leaf hoppers show that this method can 

 be used very successfully in capturing the insects [especially while immature] ; that 

 the simplest form (a flat sheet of sheet iron) was most satisfactory : that one applica- 

 tion result«'d in adding 34 per cent to the crop of hay on a plat experimented on, and 

 in one experiment leaf hoppers were captured at the rate of 376,000 i>er a<Te. 



Kerosene cMuulsiou for pl.ant lice was used once with poor success, but later an 

 application of a good emulsion by thorough methods resulted in comi>lete success. 



Grasshopjiers are mentioned avS troublesome this season and the reports of Rocky 

 Mountain grassho])pers {Coloptenus t^prctus) referred to. No present damage to Iow!» 

 is apprehended from this latter species, and methods of controlling the common 

 native species when numerous are discussed. 



The llavescent clover weevil [Sitonefi rtaveoccns] is found abundant at Amos. It« 

 dist ribution is referred to and its method of work described. Information regarding 

 its uccurrence in other parts of the State is reiinested.
