S28 THE FRUIT GARDEN. [ APRIL o

 troublesome, that few attempt it. I have tried it, 

 and many other methods, but have found none so 

 effectual and easy as the above. 



Several other insects will begin to make their ap- 

 pearance, and to attack the foliage of wall-trees, 

 currants, and gooseberries ; such as the caterpillar, 

 grub, red spider, and others. 



The caterpillar is pretty generally known, and
