 The time of travel about one month. Hence, by frequent application,, 

 large quantities can be destroyed by jarring the limbs, when the worms 

 will drop off and hang below the branches. Syrange with solution of

T. Hunt — It was in this (Stephenson) county thirty-five years ago;

G. M. Bliss — Have it with us at this time. When a boy used tar,

LeBaron — Coal tar is injurious; pine tar is not. Have tried a num- 

 ber of experiments with kerosene ; have anointed trees all over with it; 

 have used lard, linseed oil. Found the kerosene to kill the first buds. By

 kinds of tar with kerosene, and it did not kill any of them when used in 

 July and August. I put it on the trunks only. So far as my experi- 

 ments go, I know of no tree killed by the use of kerosene. 



The canker worm kills the tree when permitted to work on it three

 spring, it matures the season before.
