I have remarked above that a mature Scots pine has no rival in beauty in the genus, and indeed the charming outline, blue-green foliage, ruddy branches and roseate grey trunk of a well-grown Scot of 150 years' growth can admit no superior in comeliness; but, on second thoughts, I must admit that it has a dangerous competitor in the Monterey pine (_P. radiata_ syn. _insignis_). Native of an extremely limited range on the Californian coast, the first seedlings were raised in England in 1833. There are now several specimens recorded as over 100 feet in height. In rapidity of growth it excels all other pines, at least in the moist climate of the British Isles. One which I planted in 1884 at Monreith was blown down in 1911, and was found to be 61 feet 6 inches in height, with a girth of 5 feet 4 inches, certainly a remarkable growth in 27 years. If the timber were of a quality proportioned to the rapidity with which it is produced, the Monterey pine would indeed be a valuable tree, but our experience of it in this country differs in no respect from Sargent's report, viz. "Wood light, soft, not strong, brittle, close-grained." If it were grown in sufficient quantity it might prove good for pulping, but it is of no other economic value. Moreover, this pine is only suitable for the milder parts of the United Kingdom--the south and west coasts of Great Britain and the whole of Ireland. Almost the only exception known to me is a tree at Keir, in Perthshire, which in 1905 was about 70 feet high, with a girth of 11 feet. This must be an individual of exceptional hardihood, for in most inland districts, except in Ireland, the Monterey pine has succumbed to frost. In maritime districts it is a most desirable tree, affording splendid shelter and gladdening the eye with its rich foliage of deep but brilliant green and rugged, massive trunk.
