percentage of loss after planting to be trifling, certainly not greater than with Scots pine; but the results are not so satisfactory in southern England on hot soils. The Corsican pine, however, demands all the light it can get, being extremely impatient of shade, whether overhead or alongside. The great expectations formed about the Weymouth pine (_Pinus strobus_) when it was brought to England early in the eighteenth century have not been fulfilled. Known as the white pine of the North American lumber trade, it received its British designation from the extent to which it was planted by Lord Weymouth at Longleat. It is true that many fine specimens exist in several parts of these islands, notably that which was blown down in 1875 near Tortworth in Gloucestershire, measuring 122 feet high with 46 feet of clean bole; but as a forest tree it has never taken high rank with us, perhaps because, generally grown as a specimen, it has not been subjected to forest treatment, and the quality of the timber is ruined by the uprush of a number of competing tops. It was this habit that disfigured a Weymouth pine at Dunkeld which I measured in 1902 and found to be 13 feet 3 inches in girth at 4 feet from the ground, the clean bole being about 30 feet. I think this tree has since been blown down. Far superior to the Weymouth pine in erect habit is the Western White pine (_P. monticola_), which, in other respects, resembles the other very closely. This would be a most desirable tree for use as well as ornament, but that it has proved susceptible to attacks of the rust-fungus (_Peridermium strobi_), an organism which requires to pass alternate generations on _Ribes_ (currant). A number of fine _P. monticola_ in the famous woods of Murthly, some of which were over 80 feet high in 1906, have perished under the agency of this parasite. On the west coast, however, this fungus does not seem to have made its appearance. Of two trees of this species which I planted in 1876, believing them to be Swiss stone pines (_P. cembra_), one is now a straight, shapely tree 57 feet high, with a girth of 5 feet 4 inches at 5 feet from the ground; and both have produced plenty of seed whence a large number of seedlings have been planted out.
