The Ash-hark Beetle. 35 



Let us deal with them briefly in the order 

 given : 



The Ash-bark Beetle is injurious, both in 

 the beetle and grub state. These attack the 

 inside of the bark and bore to some extent 

 into the wood itself, leaving the roads or 

 galleries which the forester knows so well, the 

 leading or main road with its galleries 

 perpendicular to it. Miss Ormerod, in her 

 careful investigations, considers that they 

 are attracted by the newly felled ash trunks, 

 in which they propagate, and from which 

 their new broods pass to the growing trees. 

 The attack, Uke many others, seems to be 

 concentrated upon the delicate or semi- 

 decayed trees, which again points to the 

 necessity of keeping a wood or plantation in 

 a healthy state by good culture. The injury 

 arises from the separation of the bark from 

 the wood, and from the holes caused by the 

 escape of the beetles after development, 

 which absorb water and hasten decay. 



The prevention and remedy lies in the 

 cutting away of dead or dying trees, the 



promotion of growth of those which are in
