“When the Creole frigate was lying in the outer roads of Buenos Ayres, in 1819, at a distance of six miles from the land, her decks and rigging were suddenly covered with thousands of Flies and grains of sand. The sides of the vessel had just received a fresh coat of paint, to which the insects adhered in such numbers as to spot and disfigure the vessel, and to render it necessary partially to renew the paint. Capt. W. H. Smyth was obliged to repaint his vessel, the Adventure, in the Mediterranean, from the same cause. He was on his way from Malta to Tripoli, when a southern wind blowing from the coast of Africa, then one hundred miles distant, drove such myriads of Flies upon the fresh paint that not the smallest point was left unoccupied by the insects.”[965] “In May, 1699, at Kerton,” records Mrs. Thoresby, p. 15, “in Lincolnshire, the sky seemed to darken north-westward at a little distance from the town, as though it had been a shower of hailstones or snow; but when it came near the town, it appeared to be a prodigious swarm of Flies, which went with such a force toward the south-east that persons were forced to turn their backs of them.”[966] On the morning of the 17th of September, 1831, a small dipterous insect, belonging to Meigen’s genus _Chlorops_, and nearly allied to, if not identical with, his _C. læta_, appeared suddenly, and in such immense quantities, in one of the upper rooms of the Provost’s Lodge, in King’s College, Cambridge, that the greater part of the ceiling toward the window of the room was so thickly covered as not to be visible. They entered by a window looking due north, while the wind was blowing steadily N. N. W. So it appears they came from the direction of the River Cam, or rather came with its current.[967] In the summer of 1834, which season was remarkable in England for its swarms and shoals of insects, the air was constantly filled, says a writer in The Mirror, with millions of small delicate Flies, and the sea in many places, particularly on the Norfolk coasts, was perfectly blackened by the amazing shoals. The length of these masses was not determined; but they were, it is asserted, at least a league broad. It is said the oldest fishermen of those seas never remembered having seen or heard of such a phenomenon.[968]
