Note 4 — PETER KALM’s TRAVELS.

The Flying Fish (Exocoetus volitans, Linn.) are always seen in great shoals, sometimes of an hundred or more getting at once out of the water, being pursued by greater fish, and chiefly by Dolphins; they rise about a yard, and even a fathom above the water in their flight, but this latter height they only are at, when they take their flight from the top of a wave; and sometimes it is said they fall on the deck of ships. The greatest distance they fly, is a good musket-shot, and this they perform in less than half a minute’s time; their motion is somewhat like that of the yellow-hammer, (Emberiza Citrinella, Linn.). It is very remarkable that I found the course they took always to be against the wind, and though I was contradicted by the sailors, who affirmed that they went at any direction, I nevertheless was confirmed in my opinion by a careful observation during the whole voyage, according to which they fly constantly either directly against the wind, or somewhat in an oblique direction.4
