Result.—Not over 20 per cent. molted, and many of these died before 
ascending the tree. 
EXPERIMENT 11.—KEROSENE EMULSION. 
Emulsion the same as in 10. Sprayed on caterpillars on leaves and 
twigs in walnut tree. 
Result.—All disappeared within forty-eight hours after application. 
EXPERIMENT 12.—HAMMOND’S SLUG SHOT. 
Dusted leaves on which nearly full-grown larve were feeding. 
Result.—The worms changed their position soon after to a distant 
branch, but their route was clearly indicated by occasional dead larva 
hanging to the branch along which they had crawled, and soon after all 
disappeared.
