Tenderly as we should regard the juniper as a legacy from a bygone age, reminiscent of a scenery now no more, it has no qualities to recommend it for planting where it does not naturally grow, but the cypress group to which it belongs contains many foreign species which are capable of being turned to great advantage by British foresters. Although this group has been classified by botanists under a number of distinct genera, whereof the nomenclature has been repeatedly changed in a manner perplexing to ordinary persons, one valuable quality distinguishes all of them, namely, the durability of the timber they produce. It is recorded that the doors of the original basilica of St. Peter at Rome, erected in the fourth century, were of Mediterranean cypress (_C. sempervirens_), and that they were perfectly sound when that building was destroyed to make way for the present church in the sixteenth century. It is not possible to trace to its source the association of this tree with human mortality. That it was so associated in Pagan civilisation may be seen from Horace's pathetic poem: Neque harum quas colis arborum Te præter invisas cupressus Ulla brevem dominum sequetur.[25] The Mediterranean cypress is only hardy in the mildest parts of the United Kingdom, and is therefore not suitable for general planting;[26] but it has many relatives worthy of earnest attention from our foresters. About forty years ago the late Mr. Peter Lawson, of the Goldenacre Nurseries, Edinburgh, told me he expected that the American _Thuja lobbi_ (as it was then called) was destined to surpass all other conifers for British planting. The name of this tree has been repeatedly changed; perhaps it is most commonly known as _Thuja gigantea_; but the Kew authorities have decreed of late that its right name is _T. plicata_. In British Columbia, Oregon, and Washington, where it is of more commercial importance than any other tree, except the Douglas fir, it is known as Red Cedar; which does not help much towards identification, as it is quite distinct from any true cedar. In its native forests it soars to a stature of 200 feet; and, although not brought to this country until 1853, has already reached a height of 100 feet in some places. The most striking example known to me of its behaviour under forest treatment in this country is at Benmore, on the Holy Loch, where about 2,000 acres were planted in successive seasons, 1871-78, and consist now chiefly of this Thuja and Douglas Fir. It is a tree most easily raised from seed, which it produces freely in this country, and it is most easily handled in the nursery. About twelve years ago I raised about 70,000 from 15s. worth of seed; but the bulk of these, having been planted on low-lying, damp ground, succumbed to severe spring frost; while the remainder, planted on higher dry ground, now average 20 feet high. Of the timber, Professor Sargent, the leading authority on North American forestry, reports: "The wood is very
