VI. DISEASES OF FRUIT-TREES. 



powers of lime: in heat they delight; wet will not 

 injure them j frost is their only destroyer j and many a 

 time have I prayed for winter in order to see an end of 

 the caterpillars. In order to mitigate the mischief, and, 

 indeed, in a great measure to put a stop to it, look nar- 

 rowly among your plants of the cabbage kind about the 

 middle of the summer. If you see the butterflies busy, 

 expect their followers in due time. Watch the plants r 

 as soon as you see one attacked, take it entirely up, 

 shake the caterpillars from it upon the ground, put them 

 to death with your foot, and carry the plant away to the 

 pigs. "Pis very rarely that the whole or any considerable 

 part of a piece of cabbages is attacked at once j and, 

 therefore, you may, in some measure, guard against the 

 mischiefs of thi* pernicious insect of which there are 

 several sorts, some green, some brown, some smooth, 

 some hairy, and all equally mischievous. 



302. SNAIL. From the curious construction of the 

 snail, it is known to every body in town as well as 

 country. It is very mischievous, and especially amongst 

 fruit-trees, where it annoys the fruit, as well as the leaf, 

 but particularly the fruit. It is a great enemy of the 

 apricot and the plum, both of which it will eat whether 

 in the green or in the ripe state. It is very mischievous 

 amongst the plants in the garden in general ; but its 

 size and its habits and manners makes it not difficult to 

 destroy* Its places' of harbour are, behind the trunks or 

 big limbs of wall-trees, in a garden, or, round the butts 

 of the trees that form the hedge of the outside of the 

 garden. Snails lie in such places all the winter long, and 

 never stir till they are warmed into life in the spring. 

 Many persons have kept snails for a year or more nailed
