E. amygdaloides, which has stood out for upwards of twenty years, and has never been injured in the slightest degree during all that period. It grows in an exposed situation in a shrubbery, where it has shot up, and stands above the evergreens with which it is surrounded. This is likely to be the only Eucalyptus which will prove to be sufficiently hardy to withstand the climate of Scotland, and that perhaps only in the more favoured parts. The old double red Azalea Indica has stood out here for many years in the American ground, and is never injured by the severity of the winter; its growth out of doors is much slower than when under glass. In experimenting with half hardy shrubs, I find that they generally suffer less when planted as standards in a moderately sheltered shrubbery, on hanging ground with a north or west aspect, always avoiding low situations, than when planted on what is generally considered a much more favourable situation, on a south or southeast wall. Much less injury has been done to trees and shrubs in this locality during the late protracted winter than during the winter of 1860–61.

The tree from which the section exhibited is taken appears worthy of notice, on account of its large dimensions and the elevation of its site. It was grown on the estate of Glendevon, above the mansion house, on one of the Ochils called Innerdownie (2004 feet), which forms the north-eastern continuation of Termangie Hill (2110 feet), and of Bencleugh (2363 feet), the loftiest summit of the Ochil range. The altitude of the spot in which this Bourtree flourished and attained such a size is about 1000 feet above the sea. The soil is a good, lightish brown, medium loam, rather inclining to clay, upon a clay and rock substratum. Both soil and subsoil are naturally very wet, which probably may account for the size of this specimen at so high an altitude. It occupied a sheltered position amongst other hard wood trees and shrubs, and had a northern exposure. The tree was cut down in November 1873, and measured then 30 feet in height, with a finely balanced rounded head, and a straight bole of about 12 feet. It girted at 1 and 5 feet from the ground 3 feet 2 inches and 2 feet 10 respectively. The diameter of the section now exhibited, which was cut about 6 feet from the base, is 1 foot 1 inch, and the annular rings number 42, showing it to have been planted in 1831. Loudon ("Arboretum Britannicum" vol. ii. p. 1030) gives the following statistics of the Elder:-"In the environs of London there are some old Elder trees in the orchards of farm houses, and in the hedges of market gardens, but we do not recollect to have seen any above 25 feet high. In Kensington Gardens, and also at Purser's Cross, are trees upwards of 30 feet high. In the Horticultural Society's garden there are plants which in 10 years have reached the |
