GARDENING FOR ALL. 129 
weeks, with Paris green and water at the rate of one ounce to 
sixteen gallons, will usually keep the trees in a healthy 
condition. The latter is usually quite adequate. 
The stems and branches of apple, plum, pear, and cherry 
trees ought always to be cleansed from moss and lichen. A 
piece of old hoop-iron is a handy implement for scraping the 
trees with; this operation should be followed by a good 
brushing with a broom, and then the stems ought to be 
whitewashed. If the trees are regularly cared for in this 
way they will be clean and practically free from insect pests. 
The foregoing measures also effectively deal with the 
caterpillars of the Figure of 8 Moth, the Gipsy Moth, Lackey 
Moth, Small Ermine Moth, &c. 
APPLE BLOSSOM WEEYVIL.—/Anthonomus pomorum). 
This weevil is a cause of great mischief to apple trees, 
itself feeding upon the leaves, and its larve destroying the 
reproductive organs of the blossoms. More failures of the 
apple crop are due to this pest than it gets credit for. 
The female weevil proceeds from bud to bud, pierces a 
small hole in the side of the bud, and deposits one egg in 
each bud. The egg hatches in a few days, and the maggot 
feeds at once upon the pistil and stamens. The buds cease 
to develope, turn brown, and shelter the maggot. 
The remedies advised for the winter moth are suitable 
for destroying this pest, and for preventing its ravages. 
AMERICAN BLIGHT OR WOOLLY APHIS.—(Schizoneuva Lanigera). 
American blight may spread from tree to tree either by 
migration of the winged females, or it may be spread by 
means of the wind; the latter conveying the cotton or wool in 
which may be lodged eggs or young aphis. 
Dress the trees repeatedly (the affected parts) with spirits 
of wine, if on a small scale; or with the petroleum emulsion 
if on a large scale. One dressing of either will not be 
sufficient ; dress again in May without touching young shoots 
or leaves. 
MUSSEL SCALE.—/Mytilaspis pomorum ). 
Apple trees are most subject to the attack of mussel 
scale; pear trees are occasionally infested with the white pear 
scale, and the brown scale attacks various kinds of plants.
