They fly in companies of thousands together, and so close that they look like a great black cloud. When they alight on the ground they all come down in a body, and immediately begin to devourthe grass and grain; they also eat the leaves of the trees, and every green thing they can find. Thepeople dread them more than they do the most terrible fire or storm; because though they are sosmall, they destroy all the food, and leave the people ready to starve. When the inhabitants seethem coming over their fields, they try to drive them away by making loud noises or by kindlingfires; but this does little good.

It is said that a great army of locusts came over the northern part of Africa about a hundred yearsbefore the birth of Christ. They consumed every blade of grass wherever they alighted; also theroots, and bark, and even the hard wood of the trees. After they had thus eaten up every thing, astrong wind arose, and after tossing them about awhile, it blew them over the sea, and greatnumbers of them were drowned. Then the waves threw them back upon the land, all along thesea-coast, and their dead bodies made the air so unwholesome that a frightful pestilencecommenced, and great numbers of men and animals died.

Many travellers have seen these great clouds of locusts, and describe them in their books. Onesays that he saw a company consisting of so many that they were an hour in passing over theplace where he was. They seemed to extend a mile in length and half a mile in width. When hefirst noticed them, they looked like a black cloud rising in the east; and when they came overhead, they shut out the light of the sun, and made a noise with their wings like the rushing of awater-fall. Another swarm is mentioned which took four hours to pass over one spot; and theymade the sky so dark that one person could not see another at twenty steps off.

You can now understand two or three passages from the Bible which I will mention. David saysin the 23d verse of the 109th Psalm, "I am tossed up and down as the locust;" that is, as theclouds of locusts are tossed about by the wind. In the first chapters of Joel God threatens to sendthe locust among the people, because of their wickedness; and he says of them, "Before theirfaces the people shall be much pained; all faces shall gather blackness. They (the locusts,) shallrun like mighty men; they shall climb the wall like men of war. They shall run to and fro in thecity; they shall run upon the wall; they shall climb up upon the houses; they shall enter in at thewindows like a thief." An English clergyman who visited countries where the locusts are found,a few years ago, says that these verses describe them exactly as he has himself seen them.
