 ogy, p. 210, fig.)

 covered. A few of the common remedial measures mentioned. 



Forbes, S. A. — Eelation of Wheat Culture to the Chincli Bug. 

 (Proc. 9th Annual Meeting of the Society for the Promo- 

 tion of Agricultural Science, 1888, pp. 27-33.) 

 Elaborate discussion of the effect of an increasing acreage of 

 wheat on chinch-bug increase. Data derived from reports of 

 township assessors for 1888-87, and from replies by assessors 

 to circular of inquiry. Separate tabulation and discussion for 

 Southern, Western, Central, Eastern, and Northern Illinois, and 

 for the whole State. General conclusion: the chincli-bug injury 

 increases, broadly speaking, with increase of wheat area. Final 

 conclusions postponed until data have been more thoroughly 

 studied.
