ON THE CATERPILLAR. 349 



trees be looked over immediately after it is 

 discovered that the insects have begun their 

 depredations, and all that can be found, be 

 picked off'. This is readily done, and is very 

 effectual. If the insects increase very rapidly, 

 let the trees be sprinkled over with lime water 

 and powdered quick lime as directed to be 

 used in spring, also some lime be spread over 

 the roots. 



There is one of the caterpillar species that 

 attacks the Cherry tree. This insect when 

 in its fly state is a small brown moth about 

 half an inch long. It deposits its eggs 

 during the end of summer in various parts 

 of the tree, which at the ensuing spring are 

 brought to life by the influence of the sun. 

 As soon as ever it is arrived at its caterpillar 

 state, and is capable of issuing forth, it com- 

 mences its ravages. It generally brings two 

 or three leaves in contact, in the midst of 

 which it fixes a web and there conceals it- 

 self during the greater part of the day, but 

 towards night it leaves its retreat and com- 

 mits its ravages. Trees infested by this in- 

 sect must be forcibly washed over with lime 

 water, likewise be sprinkled over with pow- 

 dered quick lime. This application will de- 

 stroy all those it reaches to, but as some are 

 so closely concealed they will sometimes 

 escape this operation; a few days afterwards 

 the trees must be looked over, and all insects 

 that escaped must be pinched to death.
