NOTES AND QUERIES. 



Importance of Burning Brushwood. 



The following notes of my experience in regard to above, 

 may serve to show that (i) prompt attention to burning will 

 prevent serious destruction by weevils and beetles, and (2) if 

 circumstances prevent such adequate burning loss of valuable 

 young plants and labour is the inevitable consequence. 



For twenty-five years, or thereby, I was able to pursue 

 (annually) the regular plan of burning dead branches and 

 brushwood unsuitable for firewood. But the violent gales of 

 November 1909, and November 191 1, and of April 19 12, blew 

 down such quantities of trees, large and small, and left them 

 lying in so many directions that there was much difficulty in 

 dealing with the timber; and masses of brushwood had to be 

 left lying. Then came the war, with increased demand for 

 timber to be felled, and all the difficulties of obtaining adequate 

 labour. It was, however, possible to burn the brush and clear 

 certain areas for planting; but on one section of Bargane Hill, 

 400-500 feet above sea-level, a large area of tangled young 

 trees remained undealt with, while at the same time it became 

 necessary to risk planting an adjacent area with larch and Scots 

 pine. In July following, numbers of pine weevils appeared. As 

 many as possible were captured, placed in bottles and destroyed. 

 In the following April the pests re-appeared in increased 

 numbers, and again (though less numerous) in July. 



Result : 30-40 per cent, of the young plants have been 



destroyed, and nearly half the work has to be done over again. 



The larch plants suffered the greatest amount of damage, whole 



sections of them having been altogether destroyed.
