Large Wvch Elm (Ulmus montana) at Dalkeith — 

 blown down in November 1918. 

 A Scotch or Wych Elm standing in Lugton Haugh, Dalkeith 

 Park, was blown down recently, and the measurements of the 

 tree may be of some interest. The tree has been said to be 

 the largest of its species in Scotland. It is to all appearances 

 quite sound, although it has not yet been cut off at the root. 

 The root cut is 40 feet in length to the first limb, and measures 

 35^ inches quarter-girth over bark at the centre of the log 

 containing 350 cubic feet. The remainder of the main stem 

 measured into sections contains 124 cubic feet, and three of 

 the principal limbs contain 117 cubic feet. The smaller limbs 

 at a moderate estimate contain 50 cubic feet. The total cubic 

 content of the tree is thus 641 cubic feet. The circumference 

 of the tree at the butt is 15 feet. It will be interesting to know 

 whether any tree of this species of larger dimensions is known 

 to members of the Society. J. H. Milne Home. 



Preventive Methods against attacks of the 

 Pine Weevil. 



Text books on forest protection in referring to the attacks of 

 pine weevil on young trees, advise, quite properly, the burning 

 of all rubbish and branchwood over the cut stumps on newly- 

 felled areas, and, where possible, the peeling of the stumps of 

 coniferous trees. The burning of branchwood is as a rule 

 attended to, although the operation is very often deferred until 

 too late. The peeling of the stumps which form the breeding 

 ground for the larva? of the weevil seldom receives attention. 



On two felling areas of 40 acres and 25 acres respectively, 

 where there was reason to fear a serious attack on the 

 young plants, the precaution was taken in the months of 

 April and May 19 18 to strip the bark from the stumps of 

 both Scots pine and spruce. On the 40-acre area the trees 

 felled had been mostly of large size, but on the 25-acre area 

 the trees were of pit-wood size. In both instances very large 

 numbers of larvae were found, upwards of 150 being got in 

 one large stump of Scots pine. Many thousands were taken 

 out and killed on the two areas. There can be no question 

 that if the stumps had remained unpeeled practically the 

 whole of the young plants used in re-stocking the ground
