Barbot, after mentioning a famine that happened in North Guinea in 1681, which destroyed many thousands of the inhabitants of the Continent, and forced many to sell themselves for slaves, to only get sustenance, says these fearful famines are also some years occasioned by the dreadful swarms of Locusts, which come from the eastward and spread over the whole country in such prodigious multitudes, that they darken the very air, passing over head like mighty clouds. They leave nothing that is green wheresoever they come, either on the ground or trees, and fly so swiftly from place to place, that whole provinces are devastated in a very short time. Barbot adds, terrific storms of hail, wind, and such like judgments from Heaven, are nothing to compare to this, which when it happens, there is no question to be made but that multitudes of the natives must starve, having no neighboring countries to supply them with corn, because those round about them are no better husbands than themselves, and are no less liable to the same calamities.[331]

Of a swarm, which in the year 1693 covered four square miles of ground, a German author has made the following estimate. Observing that, when he trod on the ground, at least three were crushed, and that in a square German measure, less than an English foot, ten were destroyed; and after determining the number of these square measures in the four miles, he concluded that ninety-two billions, one hundred and sixty millions of Locusts were congregated on the surface. This is altogether a very moderate calculation, for not only is their number more compact in breadth, but they are often piled knee-high on the earth.[332]

In 1724, Dr. Shaw was a witness of the devastations of these insects in Barbary. He has given us a description of their habits.[333] For four successive years, from 1744 to 1747, Locusts ravaged the southern provinces of Spain and Portugal.[334] In a letter from Transylvania, dated August 22d, 1747, a graphic description is given of two vast columns that overswept that country. “They form,” says the writer, “a close compact column about fifteen yards deep, in breadth about four musket-shot, and in length about four leagues;

they move with such force, or rather precipitation, that the air trembles to such a degree as to shake the leaves upon the trees, and they darkened the sky in such a manner, that when they passed over us I could not see my people at twenty feet distance.”[335] This flight was four hours in passing over the Red Tower. The guards here attempted to stop them, by firing cannon at them; and where, indeed, the balls and shot swept through the swarm, they gave way and divided; but, having filled up their ranks in a moment, they proceeded on their journey.[336] In an item dated Hermanstadt, July 24, 1748, it is stated that on the day before, a hussar, coming from the plague committee, saw such a host of these insects near Szanda, that they covered the country for a mile round, and were so thick, that he was obliged to dismount from his horse, and halt for three hours, until the inhabitants of the district, coming with all sorts of instruments, beat about and forced with loud cries these pests to quit the spot.[337] In another item, dated Warsaw, August 15, 1748, it is stated that a certain prince sent out soldiers against the Locusts, who fired upon them not only with small arms, but with cannons. They succeeded in dividing the Locusts, but unluckily with the noise frightened away the storks and cranes which daily consume many of these insects.[338] Some stragglers from these swarms which so desolated Wallachia, Moldavia, Transylvania, Hungary, and Poland, in the years 1747 and ’48, made their way into England, where they caused some alarm.[339] During this grand invasion of Europe, they even crossed the Baltic, and visited Sweden in 1749. Charles the Twelfth, in Bessarabia, imagined himself, it is said, assailed by a hurricane, mingled with tremendous hail, when a cloud of these insects suddenly falling, and covering both men and horses, arrested his entire army in its march.[340]

During the devastations committed by the Locusts in Spain in 1754, ’55, ’56, and ’57, a body of them entered the

church of Almaden, and devoured the silk garments that adorned the images of the saints, not sparing even the varnish on the altars.[341]

In 1750 and ’53 Poland was again devastated by Locusts.[342] In June, 1772, there were several swarms of “large black flies of the Locust kind,” that did incredible damage to the fruits of the earth, seen in England. Salt water, it is said, was found effectual in destroying them.[343]

From 1778 to 1780 the empire of Morocco was terribly devastated by Locusts: every green thing was eaten up, not even the bitter bark of the orange and pomegranate escaping—a most dreadful famine ensued. The poor wandered over the country, in search of a wretched subsistence from the roots of plants. They picked, from the dung of camels, the undigested grains of barley, and devoured them with eagerness. Vast numbers perished, and the streets and roads were strewed with the unburied carcasses. On this sad occasion, fathers sold their children, and husbands their wives. When they visit a country, says Mr. Jackson, from whom we have gathered the above facts, speaking of the same empire, it behooves every one to lay in provision for a famine, for they stay from three to seven years. When they have devoured all other vegetables, they attack the trees, consuming first the leaves and then the bark.[344]

To prevent the fatal consequences which would have resulted from a passage of Locusts in 1780 near Bontzhida, in Transylvania, fifteen hundred persons were ordered each to gather a sack full of the insects, part of which were crushed, part burned, and part interred. Notwithstanding this, very little diminution was remarked in their numbers, so astonishing was their multiplication, until very cold and sharp weather had come on. In the following spring there were millions of eggs disinterred and destroyed by the people, who were levied “en masse” for the operation; but notwithstanding all this, many places of tolerable extent were still to be found, in which the soil was covered with young Locusts, so that not a single spot was left naked. These

were finally, however, swept into ditches, the opposite sides of which were provided with cloths tightly stretched, and crushed.[345]
