Forsyth recommends as follows : “ Take 
some sifted quick lime, lay it under the bushes, 
but do not at first let any of it touch the branches 
or leaves, then shake each bush suddenly and 
smartly, and the Caterpillars will fall into the 
lime. If the bush be not shaken suddenly, the 
Caterpillar, on being a little disturbed, will take 
so firm a hold as not easily to be shaken off. 
After this is done, sift some of the lime over the 
bushes ; this will drive down those which may 
have lodged on the branches. The Caterpillars 
ought to be swept up next day, and the bushes 
well washed with clear lime-water, mixed with 
urine. This will destroy any Caterpillar that may 
still remain.” 
Harrison says, “ during the winter season 
the eggs of the insects are deposited in crevices 
and joints of the trees, also in the ground. It is 
whilst they are in this state that iny applications 
are directed. As soon as the pruning of the tree 
is completed, I have all the refuse shoots, &c. 
raked clear away and burnt. The trees are then 
washed over with the following Mixture : A good 
portion of quick lime is put into a tub with some 
water ; in thi'ee or four days afterwards this is 
sprinkled over the trees. When it is taken out 
of the tub it is well stirred up, so that a portion 
of the lime is taken with the water. Immedi- 
ately after this is done, a quantity of powdered 
quick lime is cast amongst the branches. Instead 
of this the trees may be washed with the following
