346 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 
A number of these large trees were blown down by recent storms, 
and some of them contained over 100 cubic feet of timber. Five 
trunks were measured, and they were found to contain 136, 118, 
107, 100, and 94 cubic feet. Several of the standing specimens 
measure over 150 cubic feet, and one of the largest, but of earlier 
planting, contains 400 cubic feet. The larch also thrives remark- 
ably well, and yields a fair quantity of saleable timber. Growing 
upwards of 75 feet high, and measuring from 3 to 6 feet in girth 
at 5 feet up, the trees contain on an average from 25 to 30 cubic 
feet of timber. Besides the silver fir and larch, the Scots fir 
grows well, but not to so great size. Spruce is a better grower, 
and attains larger proportions, the cubic contents of many of the 
trees being about 40 feet. 
Deciduous trees do not grow nearly so well as the conifers, 
although beech, oak, and sycamore constitute a fair proportion of 
the wood. 
II. The Glenrosa and Glensherrig Wood, consisting mainly of 
larch and Scots fir, was planted about fifty-four years ago, and 
has grown well. At the present time it has reached its maximum 
value, for the larch is ripe and ought to be felled, as some of the 
trees are beginning to decay. A large number of the larch trees 
contain over 20 cubic feet, while some contain as much as 40 to 
50 cubic feet. The Scots fir are similar to those in Merkland 
Wood. This wood covers the south-eastern and north-eastern 
slopes of the Glenrosa and Glensherrig Hill, and. reaches to about 
800 feet above the level of the sea, at which height the trees are 
growing splendidly. The soil is of a clayey nature, with a rocky 
subsoil at no great depth. 
III. Immediately to the west of Merkland Wood, and growing 
on a similar soil resting on rock, is the Stronach Wood, consisting 
of two divisions of various ages. Both divisions are growing well, 
and contain quite a variety of trees—larch, silver fir, and Scots fir 
being the principal crop. The younger portion is thirty-four years 
of age, and contains some very promising larch ; the older portion 
is ready for felling, most of the trees being ripe. 
IV. In the neighbourhood of Brodick there is another section 
called Strathwhillan and Corrygills Wood. Larch and Scots fir 
here again constitute the bulk of the crop. It was planted thirty- 
three years ago, and is growing remarkably well. 
V. Glen Ashdale Wood is the only other wood in Arran of any 
size. It was planted thirty-five years ago, and is growing very
