appearance. Use five pounds of arsenate of lead to fifty 

 gallons of water. The spray should reach the under- 

 side of the leaves. The larvae may be trapped in strips 



of gunny sack tacked 

 around the tree, as 

 indicated in Fig. 100. 

 Remove them from 

 the folds of the strip 

 everyday. The brown- 

 tail moth, the gypsy 

 moth, the cankerworm, 

 and the tent caterpillar 

 may also be held in 

 check to some extent 

 with the gunny sack, 

 or they may be con- 

 trolled by spraying 

 with arsenate of lead. 

 Brown-tail nests which may be found at the tips of 

 twigs during the winter should be cut off and burned. 

 Gypsy-moth nests may be destroyed by soaking them 

 with creosote oil.
