of tar and oil, or blubber, mixed together, would 

 answer better. 



Lastly, a strip of oiled paper put round the tree, 

 with the lower edge projecting out considerably, 

 forms a barrier which the insect cannot pass. Let 

 the lower edge of the paper be kept wel oiled. 



In regard io all insects which are injurious to 

 trees, by clhnbing them, and committing depreda- 

 tions upon them, in various ways, we believe, from 

 the most correct informatioa we have been ena- 

 bled to obtain, from various sources, tnat, by ta- 

 king the earth away from the roots of the trees, 

 very early in the Spring, auid destroying whatev- 

 er mjiy appear*to be the abode of any insects; 

 and then returning the earth back, mixed with a 

 small quantity of sulphur, sprinkling some of this 

 upon the surface, will keep every insect from as- 

 cending any such tree. 



The etfect of sulphur, for this purpose, is very 

 durable. Probably one operation of this kind 

 will last for several years; though, on this point, 

 we have no particular information. Other repel- 

 ants of insects may be found repelants only for a 

 time, more or less limited; but perhaps may an- 

 swer the purpose for one Spring; such as quick- 

 lime, fine salt, old urine, strong soap-suds, a 

 strong decoction of tobacco, onions, &.c. &.c.

This is a bug, about the size of that which eats
