Note 209-3 — Chapter I

Compare Ritter, Erdkunde, VIII, 789-815, especially the beautiful collection of passages from the Bible bearing on the locust plague, 812 ff. Pliny, H. N., XI, 85. Volney, Voyages en Syrie, I, 305. For account of an invasion of locusts, which, in 1835, covered half a square mile, four inches in thickness, see v. Wrede, R. in Hadhrammaut, 202. It is estimated that, in England, the destruction caused by rats, mice, insects, etc., amounts to ten shillings an acre per year; i. e., to £10,000,000 per annum. (Dingler, Polyt. Journal, XXX, 237.)
