Another exhibit is a small bookcase which is labeled "Some Good 

 Books on Entomology." Each volume is fastened to the bookcase 

 by a brass chain so it cannot be carried oft'. The more important 

 entomological publications of the Station are bound and given a place 

 on the shelves. The publishers of the following works have con- 

 tributed a copy of each to this exhibit: "Smith's Economic Entomol- 

 ogy," "Saunders' Insects Injurious to Fruits," "Weed and Dear- 

 born's Birds in their Relation to Man," "Comstock's Manual of 

 Entomology," "Chittenden's Insects Injurious to A^egetables, " "San- 

 derson's Insects Injurious to Staple Crops." A few other books were 

 solicited for the exhibit, but the publishers failed to comprehend 

 their opportunity and are not represented. 



A case of spray nozzles, valves, stopcocks, pressure-guages, hose 

 attachments and other small accessories of spraying outfits are shown, 

 the pieces having been contributed by the manufacturers. A small 

 compartment of the case is given to each company contributing, and 

 in this are a number of small pieces which represent any superior 

 or new devices of merit or interest made by such company. Each 

 piece is secured to the case by a piece of brass chain of sufficient 

 length to permit the piece being removed from the compartment and 

 held in the hand for examination. (See Fig. 3. PI. 23.)

 in the other are free from Hessian fly. The wheat is of the same 

 variety and was all gathered from the same field during the same 

 season. An illustration of these two bundles is found in Bulletin 177 

 of the Ohio Experiment Station. The two jars of wheat shown in
