TCD MS 10516 folio 68 recto
[12th October 1916] fish.*
The little fish as they endeavour to escape their pursuers keep skipping over the water in a succession of leaps; they could not but make one imagine that they were tiny flying-fish that had not yet learnt the full supporting power of their fins. For I think that the succession of flights of a flying fish differ from the succession of leaps of a river fish only in that the fins of the former are better able to sustain it. (See my observation on Flying Fish).
*The fish feed most voraciously at dusk. They are extraordinarily sensitive to sudden vibrations in the atmosphere. At the report of a gun, the whole shoal, as though in obedience to an order, will in an instant disappear.
¤The tiny Euphrates Salmon reaches a great size. It was by no means unusual to capture fish weighing 30 to 30 lbs.
