DESTROYING INSECTS. 79 ' 
supposed to live partly on earth-worms, and the shell slug (Testa- 
cella ecutella) lives entirely on them. The usual modes of entrap- 
ping snails, slugs, and wood-lice, are laying down slices of raw po- 
tatoes or cabbage-leaves at night, and examining them before the 
dew is off the plants in the morning. As, however, this requires 
very early rising, a more convenient method is to lay a few flower 
pots upon their sides, near the places where the snails have com- 
mitted their ravages; and the snails, which can neither move nor feed 
unless the ground be wet with dew or rain, will generally be found 
to take refuge in the flower pots from the heat of the sun. They are 
likewise often found in the middle of the day, sticking against walls \. . 
under ivy, or in box edgings. In gardens very much infested with . eee 
snails, search should be made in winter among all the ivy and box _ Des ae 
in ea garden ; and all the snails found in a torpid state should be de- . 
them from peogiuins numerous; and, as the eggs are not laid ti 
April or May, care should be taken, before that season, to destro 
the snails that can be found. The eggs are round, almost trans- 
parent, and of a bluish white, like opal; and thev are always found 
in small clusters, buried in the ground.
