New insecticides for the cotton worm, A. E. Menke, D. Sc, 

 AND G. C. Davis. — An account of experiments made by Mr. Davis, as 

 special agent for the station, with insecticides prepared by Director 

 Menke. The aim w^as to find an effective remedy for the cotton worm, 

 which could be generally used, and which would not be as dangerous 

 to handle as the arsenites are. Kerosene soap, commonly known as 

 '• sludge," proved a failure. An emulsion of kerosene with pyrethrum 

 (li gallons to 2^ pounds) was quite effective. " Quite a number of ex- 

 periments were made to ascertain the best proportions to use in making 

 the emulsion, and it was found to be 1 pound of soap dissolved in 1 

 gallon of boiling water, and to this boiling hot mixture add 1 gallon of 

 the kerosene extract and mix with a force-pump so thoroughly that the 

 oil will not separate on standing. This will require from 10 to 30 min- 

 utes' steady work, according to the quantity and the force used. On 

 cooling, the emulsion will be a thick creamy mass, which can be diluted
