The prodigious clouds of locusts which sometimes infest the southern shores of the Mediterranean, and the tremendous devastations which they commit, have been described by many travellers; but by no one, I think, has a more vigorous picture of their movements and appearance been given than by Dr. Shaw in the following passage:—“Those,” says he, “which I saw in 1724 and 1725 were much bigger than our common grasshoppers, and had brown spotted wings, with legs and bodies of a bright yellow. Their first appearance was towards the latter end of March, the wind having been for some time from the south. In the middle of April their numbers were so vastly increased, that in the heat of the day they formed themselves into large and numerous swarms, flew in the air like a succession of clouds; and, as the prophet Joel expresses it, they darkened the sun. When the wind blew briskly, so that these swarms were crowded by others, or thrown one upon another, we had a lively idea of that comparison of the Psalmist, of being tossed up and down as the locust. In the month of May, when the ovaries of those insects were ripe and turgid, each of these swarms began gradually to disappear, and retired into the Metijiah and other adjacent plains, where they deposited their eggs. These were no sooner hatched in June than each of the broods collected itself into a compact body, of a furlong or more in square; and, marching afterward directly forwards towards the sea, they let nothing escape them, eating up every thing that was green and juicy; not only the lesser kinds of vegetables, but the vine likewise, the fig-tree, the pomegranate, the palm, and the apple-tree; even all the trees of the field; in doing which they kept their ranks like men of war, climbing over, as they advanced, every tree or wall that was in their way; nay, they entered into our very houses and bed-chambers, like so many thieves. The inhabitants, to stop their progress, made a variety of pits and trenches all over their fields and gardens, which they filled with water; or else they heaped up therein heath, stubble, and such-like combustible matter, which were severally set on fire at the approach of the locusts. But this was all to no purpose; for the trenches were quickly filled up, and the fires extinguished by infinite swarms succeeding one another; while the front was regardless of danger; and the rear pressed on so close that a retreat was altogether impossible. A day or two after one of these broods was in motion, others were already hatched to march and glean after them, gnawing off the very bark and the young branches of such trees as had before escaped with the loss only of their fruit and foliage. So justly have they been compared by the prophet Joel to a great army; who further observes, that ‘the land is as the garden of Eden before them, and behind them a desolate wilderness.’
