infest the next year's heads, it would be desirable to clear wild 
grasses from the neighbourhood of the seed-land, and to change 
this as far as could be managed from an infested spot. To 
destroy the maggot in breaking up ground it would be perfectly 
effectual to double dig it, or deeply plough it, if it could be 
lelt undisturbed, excepting the immediate surface, until August 
in the following season.

From reports sent in each season it appears that great harm 
is ofren caused in the fruit-srrowin? districts bv the small greenish 
looper caterpillars of the winter moths, which destroy the leafage 
of apple and other trees when expanding. As the females of 
these moths {Cheimatob'a bntmata), and 
others which come out during the winter, 
have only abortive wings, and conse- 
quently have to walk up the trunks of the 
trees to reach the branches on which thev 
lav their esss, it was sug-eested that mea- 
sures should be taken to prevent this, and 
the plan has been tried in an infested 
locality with perfect success. 
The trees were smeared for a foot or 
two above the ground with " Davidson's"' 
composition : and bv the 11th of Xovember 
upwards of 500 of the creeping female moths (specimens of 
which were forwarded) had been caught fast in the sticky 
material. Each of these moths lays from 100 to 300 eggs, 
therefore much coming injury was prevented. 
Any sticky material which would keep soft for awhile would 
be equally serviceable, and the plan would answer as well for 
1, Male ; 2, Female.
