Having undoubted proof of the readiness with which many plants, indigenous to the cold, as well as to the hot, regions, may be naturalized at St. Helena, it must excite some surprise to be informed, that no public measures have yet been taken to stock the island with a variety of quick-growing and useful trees; which, being collected on favorable spots, might serve as the depôt for future supplies. The various species of palms thrive amazingly, as does the peepul; of which, for a long time, there was only one in the island, and no person could tell whence it came! It seems curious, that peaches should thrive so luxuriantly, and acquire such an admirable flavor, notwithstanding the dryness of the atmosphere: formerly, this fruit was in such abundance, that large quantities used to be given to the hogs. Unhappily, an insect, only to be distinguished by the aid of glasses, was imported with some slips from the Constantia vines: these attacked the peach trees, devouring their bark, and destroying at least nine-tenths of their number. It is said, that every means have been tried to annihilate these minute plunderers, or to deter them from their wonted attacks, but without effect. I recollect, that, about twenty years ago, a premium was given by some association, (probably the society for the encouragement of arts,) to a person who discovered a means of ridding trees from this description of clustering insects. It was very simple; and was effected by boring holes with a gimlet, obliquely downwards, into the body of the trunk, near the ground, and filling them with quicksilver; after which the holes were closed by means of pitch, or plugs of wood. As possibly this has never been essayed at St. Helena, I give it a place under the hope of its proving useful: it is, however, said to render evergreens deciduous.
