The only notable walnuts which I can remember to have seen in Scotland are one at Gordon Castle, another at Cawdor, and a third at Blairdrummond. The first of these would have been a magnificent tree had it been subjected to forest discipline in youth, and so expended its vigour in height rather than breadth. It is only 60 feet high, with a girth of 10 feet, but it covers with its huge branches a space nearly 80 feet in diameter. The tree at Cawdor is about 65 feet high, with a girth of 15 feet 7 inches; and that at Blairdrummond is the tallest of the three, with a girth of 13 feet. Such dimensions cannot compare with those which the walnut attains in Southern Europe. A writer in the _Gardeners' Chronicle_ described one in the Baidar Valley, near Balaclava, which yields from 80,000 to 100,000 nuts annually, and belongs to five Tartar families, who divide the produce between them. Still, there are so many fine examples of what this tree may become in Great Britain that one may well ask why the production of its timber has been so utterly neglected. Mahogany and other foreign woods have usurped its place in the cabinet trade; but we still import large supplies of walnut, not only for panelling, but for the stocks of army and sporting small arms. For that purpose it has no equal, owing to its lightness, strength, the nicety with which it can be cut to fit gunlocks, and because it never warps nor swells when exposed to wet. "During the last war," says Selby in 1842, "when most of the continental ports were shut against us, walnut timber rose to an enormous price, as we may collect from the fact of a single tree having been sold for £600; and as such prices offered temptation that few proprietors were able to resist, a great number of the finest walnuts growing in England were sacrificed at that period to supply the trade.[14] Some years ago the War Office authorities sought to extend their sources of supply by substituting one of the superb kinds of timber grown in our colonies; but although twenty different woods were submitted and tested, none was found suitable except the American black walnut. This (_Juglans nigra_) is a larger tree than the European species, growing to a height of 150 feet with a girth of 15 to 20 feet in the middle States of North America. It has now become very scarce, owing to reckless destruction of the forests; but there are some specimens in England already approaching the dimensions of those in Ohio, Indiana, and Kentucky. For instance, there is one at the Mote, near Maidstone, over 100 feet high, with a girth of 12 feet 6 inches in 1905, and another in the public park at Twickenham, 98 feet high in the same year, with a girth of 14 feet 3 inches. Besides some lofty black walnuts of the ordinary type at Albury Park, Surrey, there is one very handsome tree on the terrace, near the house, distinguished as a variety under the title _J. nigra alburyensis_.
