 crops in 181)2. Descri]>tions, life histories, and remedies are given, and supplemented 

 by 10 colored plates. The following species are treated: The currant moth {Incur-

The horn fly, C. H. Fernald, (Massachusetts Hatch Sta. Bid. 24, pp. 11-15, figs. 2).— 

 A popular account of the horn fly (Hcematobia serrata), with figures, description, 

 life history, damage, and remedies. Sprinkling lime over the fresh dung or spread- 

 ing it out to dry quickly before the larv;e have matured is advised, as also applica- 

 tions of train, or flsh, oil and carbolic acid to the cattle, or spraying them with kero- 

 sene or fish oil emulsion. 



Insect enemies of legumes, G. McCarthy (Xorlh Carolina Sta. Bui. OS, pp. 152- 

 154). — Descriptive notes and life histories arc given for the pea weevil (Brnchus pisi), 

 bean weevil (B.faba), clover-seed midge (Cccidomyia Icgnminicola), c\ovcr-root borer 

 (Hylasies trifolii), and clover-hay worm (Aaapia costalis), and remedies advised for 

 their destruction; plowing under for the midge and root borer, and carbon bisuli)hido 

 for the others.

FOODS— ANIMAL PRODUCTION. 



Changes taking place in the silo, P. Collier [New YorJc State 

 Sta. Up. 1892, pp. 102-173). 



Synopsis. — The loss in ensiling was stndieil in 3 experiments with corn fodder and 

 3 with sorghum. The average loss for all amounted to 12.6 per cent of the 

 dry matter, 18.5 of the albuminoids, and 26.6 of the starch and sugar. The 

 amide nitrogen increased 3.7 per cent during ensiling. With one exception the 

 silage was in good condition when taken out. 



To observe the changes taking phtce in ensiled corn and sorghum, 



experiments were made with each in 3 different years. In each case 3 



bags holding- 50 lbs. each were filled with the green material and placed 



in different parts of the silo. The corn was in a "medium glazed"
