Cockroaches, Destruction of, A Suggestion for the. By C. W. Howard (Jour. 

 Econ. Entom. vol. x. Dec. 1917, pp. 561). — Recent successful attempts to kill 

 bed bugs in dwelling houses by superheating makes the possibility of killing 

 cockroaches by the same system feasible. It was found that an exposure to 

 temperatures between 122 0 F. and 140 0 F. for twenty minutes killed 100 per cent. 

 Temperatures below 120 0 F. gave variable results. The practical application 

 of this knowledge is of considerable difficulty owing to the habit of the cock- 

 roach hiding in cracks, &c. — G, W< G. 



Coconuts. By C. F. Kinman (U.S.A. Exp. Stn., Porto Rico, Nov. 1916, 

 pp. 25-28). — The effect of a fertilizer containing 6 per cent, nitrogen, 8 per cent, 

 phosphoric acid, and 12 per cent, potash on the coconut palm is not apparent 

 during the first two years, but an application of 20 lb. per tree of such a mixture 

 resulted in an increased yield of nuts amounting to 60 per cent, in the third 

 year.— 5. E. IV.
