make up a mixture of oil, or blubber, with suitable 

 proportions of sulphur and Scotch snuff; and with a 

 brush lay this on the scraped part, forming a ring 

 round the tree an inch or two wide ; and no insect will 

 ever attempt to pass this barrier, as long as the compo- 

 sition has any considerable moisture left in it. 



Let it be repeated when it inclines to harden ; though 

 perhaps this is not necessary. Let it be done early in 

 the spring, before the insect comes from the ground. 



Another method, which it is believed will be found 

 equally effectual, though attended with more trouble, 

 is to scrape off the shaggy bark from the body of the 

 tree ; and then whitewash that part well with lime and 

 water Snd a little sulphur added. 



In place of this, however, Mr. Forsyth directs that 

 the body of the tree be covered with a composition of 

 old urine, kept some time for the purpose, soap-suds, 

 fresh cowdung; and this he says will keep off all in- 

 sects. Let it be laid on plentifully. 



Another method, we have heard recommended is to 

 fasten a strip of sheepskin, with the wool outwards, 

 round the body of the tree, taking care that no place 

 be left for the insect to creep up between the strip and 

 the bark. The wool should be frequently combed to 

 keep it loose. 



A streak or ring of tar made round the body is also 

 effectual, as long as the tar remains soft ; but, as it 

 soon becomes so hardened on the exterior, that the in- 

 sect can crawl over, it requires to be repeated very 

 frequently. Perhaps such a ring of tar and «il, 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 well oiled.
