of the leaf, the resultant maggots then forming little tunnels 
and eating the tissues as they work along. The maggots or 
the pupae can be seen in the leaves, and may be dug out with 
the point of a knife. The only known remedy otherwise is to 
pick off and burn the worst infested leaves. The other species 
(Phytomyza affinis) deposits its eggs in the tissues of Mar- 
guerites, Chrysanthemums, etc., and from these larvae are 
hatched which feed similarly to the Holly Leaf maggots. In 
this case crushing the maggots in the leaves, or digging them 
out, or pulling off and burning badly infested leaves are the

Explanation — Fig. 1 shows the eggs, which are of the size of shot, and laid in damp 
soil. Fig. 3 is a baby snail. Fig. 4 is a full-grown snail (Helix hortensis), with its shell

of hearthstone in a pail and pour on as much paraffin oil as it 
will absorb, then add two gallons of water. Let the liquor 
stand for three days, remove all scum from the surface, and 
apply with a fine sprayer. 
Mice.— Ordinary Mice, and Field Mice or Voles, are partial 
to newly planted bulbs. Moistening the bulbs and rolling them 
in powdered red lead before planting often preserves them 
from molestation. 
Red Spider (Tetranychus tellarius). — This is a small 
mite which congregates on the leaves of roses in hot, dry 
situations, and under the protection of a fine web sucks out
