On the sandy soil of parts of Surrey, especially about St. George's Hill, the locust thrives well, reproducing itself freely from self-sown seed, and forming very lovely objects when covered with fragrant white blossoms in June. Even in such parts of England where it does best, it is not profitable to let it stand longer than, say, twenty or thirty years, when it makes admirable fencing and gate-posts, which are almost imperishable. At a greater age the trunk becomes coarse and deeply furrowed, often becoming rotten towards the centre. Elwes mentions a locust tree at Frogmore, near Windsor, as the largest in Britain, which he found in 1908 to be 88 feet high by 14 feet 7 inches in girth. One about the same height at Bowood, Lord Lansdowne's place in Wiltshire, was slightly taller, but girthed only 8½ feet. In France and Italy the locusts thrive as vigorously as in their native continent, and are exceedingly beautiful during the flowering season. They also make very effective hedges, being regularly cut over, when they send up long and strong shoots armed with murderous thorns. Few trees stand the drought, heat, and smoke of London as well as the _Robinia_, which carries its verdure unchanged long after the limes and elms have become seared and unsightly. Many a time, when Parliament continued sitting through and after the dog days, have I refreshed my eyes by gazing upon a fine _Robinia_ which stood at the corner of the late Lord Sefton's house in Belgrave Square. But that tree is no more, for, when the house changed hands after its former owner's death, and was put into the hands of builders and decorators, they felled my friendly _Robinia_. There are three species of _Robinia_ seldom planted in this country--namely, _R. hispida_, _R. neo-mexicana_, and _R. viscosa_, all with beautiful pink or rose-coloured flowers. Of these, the first-named, a native of Carolina, is the most desirable, but it is even more brittle than the locust or false acacia. Its blossoms are so exquisite as to entitle the tree to the advantage of being trained on a wall.
