fruit-destroyers, now almost baffles all our art. It is thought by 
some, that the “ green-wash,’’ as recommended for the canker-worm, 
will greatly help dispose of this pest by poisoning the moth. Oth¬ 
ers recommend the use of various clap-traps, in which to catch the 
larva as it issues from the fruit. Careful experiments made by Dr* 
Le Baron, show that six-inch-wide strips of old carpet, or other old 
cloth of considerable thickness and pliability, long enough to go 
twice around the body of the tree, immediately below the branches, 
and tied or tacked loosely, so that the worm may find a lodging, are 
very efficient traps for the codling. These hands must be ap¬ 
plied within a month of the first setting of the young fruit, and ex¬ 
amined as often as every two weeks from their application, until the 
first brood of larva have left the fruit, or say about the middle of 
August. They can then remain on the trees until the fruit is 
gathered in the fall. The worm seeks out such a retreat in which 
to pass through the transformation process. The second brood of 
worms do not complete their transformation until spring, and there¬ 
fore need be destroyed only at the end of the season. 
These hands are to be dipped in hot water, or run through a 
wringer to destroy the worms in their different stages. These 
bands may be made of thick, cheap, brown paper, which would go 
through one season if carefully handled. It is found that a second 
band nearer the ground is a gain, as nearly as many worms pass up 
from below as come down from above. It is also found that very 
few “ windfalls 11 have the worm in them soon after they have fallen, 
so that the old way of picking and destroying the windfalls, is of 
little avail. 
These seemingly slow and laborious processes will well repay the 
orchardist, by the enhanced value of the crop in quantity and qual¬ 
ity. If our state alone could be exempt from the codling moth for 
this year 1875, it would be worth, say one million of dollars to the 
producers. Severe and extensive drouths produce famine, but while 
vegetation waits, the soil rests and recuperates. 
But 'while the moth does some good by thinning out an over crop 
of apples in early summer, the outlay of bloom, and the prematurity of 
fruit, are a heavy drain on the vital powers of the tree, with no re¬ 
turn to the producer.
