 their appropriate place.

 the longitudinal grooves which have been cut in 

 the roots, the moth issuing in the spring follow-

 of ashes or lime may be drawn up, or, still better, 

 a band of tarred paper or similar protection may 

 be tied around the trunk. In the fall or early 

 spring the trees should be examined, and if the 

 gummy exudations are found, the base should be

A caterpillar, a leaf roller, and a few minor
