leries \scr pi. 22, 23]. One of these galleries was partly transverse, extend- 

 ing about 1-4 of the distance around the trunk. This injury could probably 

 be helped by bridge grafting. In any event it is advisable to cover such 

 wounds with grafting wax or even fill the galleries with mortar, grafting 

 wax, or some other material to protect the wood from the elements. Occa- 

 sionally much digging can be saved by injecting a little carbon bisulfid into 

 an inhabited gallery, but the objection to this procedure is that one can 

 never be certain of destroying the grub. We consider it better to expose 

 the gallery far enough, so that a sharp wire can be inserted and the borer 

 killed. A wound or two with such an instrument means its death and there 

 is no necessity of securing the grub itself. 



Wounds made either by the borer or by a person looking for it, should 

 be cleaned and plastered with a cement of fresh cow dung and lime, in 

 order to hasten their healing. 



In sugar maple groves, Mr Kirkland advises that the underbrush be left 

 as much as possible, as he has observed that the clearing up of the shrubbery 

 has repeatedly been followed by severe injury from this borer. The beetles 

 are known to be sun-loving insects and it is very probable that they would 

 place their eggs where the conditions were most attractive.

Deformed and frequently enlarged trunks of maples showing brownish powdery 

 borings near the surface, with here and there a small circular orifice, indicate the work of 

 this insect. 



The riddling of new tissues around healing wounds on maples is usually 

 the work of this borer. The round holes through the injured bark and the 

 brownish, powdery borings are very characteristic of this caterpillar. It 

 has a special fondness for the tissues growing over wounds, though occa-
