PEACTICAL FOBESTBY. 



The beetle is about half an inch long, and nearly black. 

 One remedy, probably the best, is to place fresh pieces of 

 pine bark on the ground, beneath the infested trees, and, by 

 shaking the trees and examining the traps the following 

 morning, many may be destroyed. 



Bostrichus typographic is another pest of our woodlands, 

 and may frequently be seen, like fine white wool, spreading 

 over the stem and branches of the silver and other firs. It 

 spreads with terrible rapidity, first appearing in small patches 

 here and there on the bole, and particularly on the under 

 sides of the branches. The tree infested soon becomes un- 

 healthy, and frequently dies off prematurely. Trees growing 

 in low-lying, heavy ground would seem to fall a first prey to 

 this insect. 



Bostrichus laricis is nearly alUed to the former, but its 

 devastations, which are, however, not very deadly, are 

 principally confined to the larch. It is usually known as the 

 "larch blight." 



The Elm Tree Destroyer (Scolytus destructor} is about 

 two-tenths of an inch long, stout and cylindrical, and usually 

 confines its depredations to the elm. 



In the beginning of June this beetle bores into the inner 

 bark, where it forms galleries, alonij the margins of which 

 are laid the eggs. Cutting down and burning badly-attacked 

 trees is the best remedy, but promoting exuberant health of 

 the infested specimens by means of liquid manure has been 

 fraught with promising results. 



The Goat Moth (Cossus ligniperda) is most frequently 

 found on the willow, oak, lime, and other trees. Being not 

 only one of our largest native moths, but also one of the most 

 destructive, its ravages are much dreaded, the holes or 

 tunnels made by the moth being of large size large enough 

 to admit the little finger. Filling up the tunnels with a 

 mixture of soot, lime, and cow manure is an excellent remedy . 



The Pine Shoot Moths. (Retinia buoliana and B. 

 turionella) would seem to be more plentiful in this country 

 than is generallj 7 supposed. Quite lately I visited a large 

 plantation of young Scotch fir, the terminal buds of which 

 were greatly injured by the caterpillars of this elaborately-
