As tlic eggs are deposited on llic trees only after tlie female 

 lias ascended, the manifest remedy and protection is to prevent 

 the female from crawling np the trunk. For this purpose 

 almost numherless things liave been invented, some of wliich 

 have been in a measure successful, none more so than the strip 

 of tar painted on the trunk of the tree while the females are 

 active. 



There have been various methods tried of applying this tar, 

 the most efficacious of which being simply to tack around the 

 tree a strip of thick brown paper about fifteen inches in width, 

 and over this to paint a thick coating of a mixture of tar and 

 grease two or three times in twenty-four hours, or at least once 

 during the day, and once in the evening, during which latter 

 time the females swarm up the trees in the greatest numbers. 

 It is essential that the tar be applied in a liquid form and suffi- 

 cient grease should be mixed with it to give it the requisite 

 thinness. The female moths on endeavoring to pass over the 

 tar are arrested, and hundreds, sometimes thousands, are 

 caught on one tree in a single night. I am acquainted with a 

 gentleman, owner of a large orchard in Middlesex County, who 

 keeps one or two men employed through every night during 

 the season of the ascent of the female moths, in applying the 

 tar, and he assures me that if he were not careful thus to keep 

 them in check during the night, that they would completely 

 overrun his trees. 



After the moths have obtained access to the trees and laid 

 their eggs, there is very great difficulty in ciiecking their 

 ravages. Mr. Marshall S. Rice, of Newton, gives his experi- 

 ence and method of overcoming these pests, as follows : — 



" Before the foliage was much eaten, and when the worms were about two- 

 thirds grown, on a warm still day, I took a cane-pole about twenty feet Ions, 

 and went into my orchard to see what could be done. I took my stand a 

 little way from a tree, and beginning with the top limbs on that side, I shook 

 and jarred them thoroughly ; and most of the worms from those limbs let 

 themselves down on their own rope, some to lodge on the under branches, 

 others to hang in the air near the ground ; then I sliook the next tier of limbs 

 in the same way; and so continued till the whole side of the tree had been 

 thoroughly shaken, and the worms in great numbers hung in the air under 

 the lower limbs; then by horizontal strokes with my pole, under the limbs, 

 and as near them as possible, I let down all the culprits which were within 

 my reach. I then went through the same operation on the other side of the 

 tree. I went to the second and third tree and did the same. Perhaps 1 was 

 half an hour doing the three trees. Now I had got a large portion of the 

 worms to the ground, but not knowing what they would do with themselves, I 

 went to the first tree operated upon to e.\amine ; and I found the creatures 

 determined not to be foiled by this mode of attack; all, from every direction, 

 were scampering toward the tree and some of them crawling up its trunk. I 

 concluded if I had failed to catch the grubs I could arrest the worms with tar. 

 1 directed my man to get some tar and warm it, and bring it as soon as possi- 

 ble ; he did so, and perhaps in fifteen minutes he had it there. I brushed
