imitate the vibrations produced by the hammering of wook-peck- 

 ers, and the curcuhos drop to escape them, while shaking simply 

 imitates the motion produced by the wind. There are also a num- 

 ber of patented and unpatented devices to catch these insects by 

 machinery, which jar the tree, collect the beetles, and grind them

There are many other methods in vogue, and a few of them 

 are of some use. Shingles laid close to the trunk of a tree, the 

 fruits of which are to be protected, will early in the spring ofifer a 

 shelter for the beetles that have fed upon the trees during the 

 night, and which, towards morning, leave it — on foot — to hide 

 during the day. By turning over and inspecting these traps one 

 can destroy many beetles. 



Although the curculio is well protected as long as still en- 

 closed by the plum, it has nevertheless many enemies, and these 

 destroy large numbers of the full-grown larvae of the "Little
