 however, be trapped in two 

 ways : one. by placing sods 

 of grass upside down on 

 the ground near the straw- 

 berry plants and having 

 those that collect under- 

 neath killed ; or by spread- 

 ing small heaps of bran 

 or clover poisoned with 

 arsenate of lead or Paris 

 green about the beds in 

 spring or autumn, thelarva? 

 at night are attracted to 

 these and are poisoned.

 turns them up, when they 

 may be picked up and
