Sawfly is known to have done much damage in Denmark about sixty 

 years ago, and in more recent times has devastated the larch forests of 

 North America. How long it has been present in Great Britain is not 

 known, but its presence was not officially confirmed till 1906, when it 

 was reported from Cumberland. It has since been found over a large 

 area in Whales, a wide district in the north of England, and a very 

 considerable area of the soath of Scotland. It probably exists in other 

 parts of the Kingdom. There is reason to believe that up to the 

 present the general attack is but slight, but in the spots where the 

 prevalence of the pest is greatest many thousands of trees have been 

 killed. Nor is it likely that the plague will go no further. There are 

 evident signs that it has spread in recent years, and it is recorded that 

 in the United States and in Canada it did not stop till 50 to 100 per 

 cent, of the matured larch over vast areas was destroyed, with the loss 

 of many billions of feet of timber. The serious nature of this prospect
