SO well. Larch disease, excepting where the tree is in unsuitable 

 soil, or in an unsuitable situation, is not at all troublesome if the 

 woods get proper treatment. 



Cluiies Wood. 



"This, which is the first to be visited, is a plantation about 

 50 acres in extent and 41 years old. There is at present an 

 average crop of about 340 trees per acre on the ground, with a 

 height of 52 to 58 feet. It was planted practically as pure 

 larch in the drier ground, the wet parts having been planted 

 with Scots fir. The wood was thinned very irregularly, part of 

 it having been thinned many years ago, but other parts not 

 being touched. As a result, the thinned part contains some 

 fairly heavy trees, while, where no thinning was carried out till 

 too late, the trees are very light and slender. A small section 

 of the wood to the east of Clunes Pier is interesting as showing 

 the effect of keeping the trees too thick on the ground. Here 

 there are about 440 trees per acre, and these have a height of 

 from 60 to 65 feet. The crowns of the trees are all exceedingly 

 small, being only 12 to 13 feet long, and the average annual 

 increment is also small. The trees are now so slender in pro- 

 portion to theiir height that it is difficult to know how to treat 

 them, because, if they are thinned, they sway so much that the 

 buds get lashed off, and many of the trees get interlocked. 

 About 150 trees per acre were removed three years ago, and 

 the section is now left as an experimental plot. 



Tor a Mhiult. 



"This wood was the second to be inspected. Its extent is 

 about 90 acres, and it comprises about 60 acres of 64 years of 

 age, and 30 acres 40 years of age. The plantation is almost 

 pure larch with a few spruce, oak and birch. In the lower part 

 of the wood there is a considerable number of naturally grown 

 beech. All over there is an average crop of about 250 trees per 

 acre, and these have all remarkably long clean stems of an 

 average height of 75 to 80 feet. 



Natural Oak Wood. 



" The natural oak woods extend along Loch Arkaig side and 

 Loch Eil side, and are approximately 1700 acres in extent. 

 These woods are of various ages, from about thirty years
