best of those which I saw might measure 60 feet timber height by 18 inches quarter- 
girth or 135 cubic feet. In the best stocked areas the trees might average 120 per 
acre at 120 years old, of which forty trees of the first class would average perhaps 
40 feet, forty second class 25 feet, and forty of the third class perhaps 12 feet each, 
or about 3000 feet to the acre. But these figures are only a rough estimate, as the 
King’s trees are not cut for sale, and in consequence Mr. Michie could not give 
me exact figures, but thinks they are worth from 6d. to 8d. per foot standing. 
The Black Wood of Rannoch is an ancient natural pine wood extending for 
about three miles along the south shore of Loch Rannoch, and though there are no 
trees of exceptional size, there are many very picturesque ones, which are protected 
by the owner, B. C. Vernon-Wentworth, Esq., whose residence at Dell is near the east 
end of the wood. The largest which I measured was 91 feet by 11 feet 7 inches, 
with a very spreading base 15 feet 5 inches round at one foot from the ground. The 
greater part of the wood is open and covered with long heather, among which 
seedlings were fairly numerous wherever the soil was exposed. Many of the large 
trees were blown down thirteen years ago, and their timber, which was of very fine 
quality, was used by Sir J. Stirling Maxwell in the interior work of his house at 
Corrour. 
There is an excellent account of the Black Wood of Rannoch and its history in 
chap. xxxiv. of that admirable book, Hunter’s Woods and Forests of Perthshire, 
which, though now getting out of date, as it was published in 1883, gives a better 
account of the great estates and their trees than exists for any other county in Great 
Britain. In this work dimensions are given of the finest trees then existing in the 
Black Wood, which are remarkable more for their great girth, spreading and 
massive branches, and picturesque appearance than for their height. 
On the shores of Loch Hourn, on the west coast of Inverness-shire, there are 
many native pines scattered among the birches, but none of large size, a few of 
those near the sea resembling the stone pine of Italy in habit. Henry observed 
that many of these trees do not ripen seed. 
With regard to the elevation at which the Scots pine grows in Scotland, we 
have various somewhat conflicting estimates. Mr. Michie tells me that Craig Doin 
(1900 feet) is about the highest level he knows it to reach in Ballochbuie. Mr. 
Seton P. Gordon, however, says* that he has seen a young Scots pine growing at 
a height of about 2700 feet not far from the source of the river Dee on the south 
slopes of Brae Riach, though he regards this as very exceptional. Mr. Hugh Boyd 
Watt * also considers 2700 feet quite an unusual altitude, and says, “From personal 
observations made on and around the Cairngorm mountains (and in no other district 
in this country do forest trees attain higher levels) I can say that even at 2000 feet 
above sea-level the Scots pine has difficulty in holding its ground. ... On the 
southern slopes of Beinn a’ Bhuird (Glen Quoich) considerable numbers of fairly 
well-grown Scots pines reach up from 2000 feet to 2100 feet, and I know no other 
place where what may be called the forest line is so high. . . . In other localities, 
apparently favourable to their growth, the pines do not in any numbers exceed an
