Note 54 — Chapter XXIII

Barrow, who wrote about this period, and who gives a remarkable account of the devastations of these insects, probably alludes to this very circumstance when he says,

“The present year is the third of their continuance, and their increase has far exceeded that of a geometrical progression whose ratio is a million. For ten years preceding their present visit the colony had been entirely freed from them. Their last departure was rather singular. All the full-grown insects were driven into the sea by a tempestuous northeast wind, and were afterward cast upon the beach, where, it is said, they formed a bank of three or four feet high, which extended from the mouth of the Bosjeman’s River to that of the Becka, a distance of near fifty English miles; and it is asserted that when this mass became putrid, and the wind was at southeast, the stench was sensibly felt in several parts of Sneuwberg.... The larvæ at the same time were emigrating to the northward. The column of these imperfect insects passed the houses of two of our party, who assured me that it continued moving forward, without any interruption except by night, for more than a month.”
