ports successful cultivation, in beef broth, of bacterium parasite of 

 the chinch bug, lately described by Burrill as Micrococcus insec- 

 forum; but opportunity failing for experiments upon insects 

 with artificial cultures, conclusive proof is wanting that this Mi- 

 crococcus is destructive to chinch bu£>s. Writer believes from 

 personal observations and evidence of correspondents that first 

 brood of chinch bugs was either destroyed by rains and cold, or 

 so hindered in deposition of its eggs that only one brood was gen- 

 erally developed in Central and Northern Illinois. Considers it 

 unlikely that chinch bugs will appear in destructive numbers in 

 this State next year. Can find but small number hibernating.

Claims that soaking spring seed wheat in brine for two weeks — 

 drying off before sowing— will render the grain so much earlier 

 and more vigorous that chinch bugs will not injure it.

Mention of Thomas's studies and predictions and the injuries of 

 1881; of appearance of the pest in 1882, and probable checking 

 by rains; and of remedies and preventive measures, — irrigation, 

 burning of the hibernating bugs, early sowing of spring wheat, 

 and clean culture being especially emphasized, and the use of the 

 kerosene emulsion advocated.

Recalls previous predictions, based on rainfall record, that chinch 

 bug should be expected in 1880 and 1881 if those years be dry, 

 and advice to farmers to rely on oats rather than corn for the 

 latter year. Remarks on fulfillment of prediction and loss of 

 farmers because of failure to follow recommendation. Considers 

 't -beer folly to talk of protecting crops by topical applications.
