days later; and the third fourteen days after that. As 
these are poisonous washes, they should never be used 
on fruit trees or bushes when the fruit is of any size. It 
is advisable to add twice as much lime as Paris green 
or London purple, in case there is any soluble arsenic in 
them which might do injury to the foliage of the trees. 
Winter Moth. — This is another most destructive 
insect in the orchard. The female crawls up the stems 
of fruit trees during the winter season, commencing to 
lay her eggs in the clefts of branches, &c., in October 
or November. This goes on all through the winter. 
In the spring time these eggs are hatched and the larvae 
make their appearance. When full grown these are about 
1 in. in length. They are of various colours: grey, 
green, or even black. They feed rapidly on the foliage 
of many of the fruit trees, or even on the buds of flowers. 
When full grown, the larvae lower themselves to the ground 
by means of a thread, and turn into pupae in the soil. 
Sometimes a few pupate under the rough bark of the 
trees. It is during May and June that these larvae are 
changed into the pupae, the perfect insects appearing the 
following winter to carry on the work. If a late brood 
is produced, they may even attack the young fruit. 
Now for such destructive insects every means possible 
must be taken to keep them in check or to destroy 
them entirely A good method is to place grease bands 
on the trees, but care must be taken to get grease-proof 
paper; otherwise considerable injury may be done to the 
trees themselves. The paper should be tied above and 
below with bast, then a grease of some kind, which will 
remain soft for a long period, should be smeared over
