UNDER THE BARK. 47

 expected to find, and for wliich he has been long look- 

 ing. Without further preface I will give an account 

 of a few hours just spent in looking under the bark. 



Close to my house — only across the road, indeed —

 are some young crushed laurel leaves, the odour of 

 which is fatal to beetles, and prevents them from eat-

As I have already mentioned, this is a good time 

 for searching under the bark. The severe frosts of
