PRACTICAL FORESTRY. 



beds the attack of the wireworm is always most pronounced. 

 In the ease of fresh nursery ground paring off and burning 

 a couple of inches of the top soil in the autumn has been 

 attended with excellent results, as has also dressing the 

 ground with gas lirne. When seedlings are attacked hand 

 picking, with the use of sliced carrots, mangold, or 

 potatoes, varied with pieces of oilcake as a bait, are to be 

 recommended. Dressing the seeds with red lead is very 

 advantageous to prevent birds and mice from attacking 

 freshly-sown quantities. Injury from wireworm is not 

 likely to cause any serious consequences alter the first year's 

 growth of the plants, especially if the ground has been 

 kept clean arid free frc n weeds during the egg-laying 

 season in June. 



The above are only a few of the many insects that injure 

 our forest trees : but those treated of are such as are most 

 familiar to the forester, and whose attacks he has most 

 frequently to wage war against. 



Remedial measures are frequently of little avail, more 

 particularly when a whole wood or plantation is attacked ; 

 but with single specimens the numbers may readily be 

 lessened by the methods suggested. 



Keeping the woodlands free of dead and dying trees arid 

 branches is a preventive of insect attacks that should never 

 be neglected. 



As showing the injury that can be inflicted on our forest 

 trees by some of these insect pests, the following cases may 

 be mentioned : 



During fifteen years (between 18^3-68) the spruce in East 

 Prussia, Poland, and Russia was killed over an area of 7,000 

 square German miles ; while in the Bavarian forests, the loss 

 to the Revenue in one year was <40,000. 



In both cases the destructive insect Lipans monacha was 

 the cause of injury. 



Larch disease. In all probability the larch disease or 

 larch canker owes its origin to the minute spores formed 

 in the fructification of the now well-known fungus Peziza 

 Wilkommii. It has been pretty conclusively proved that 

 these spores can only find a footing where the rind of the
