Note 6 — XXII.—A Story of the Great Famine.
Reading edition
The native hunters say that if you shout at an iguana he does not move or take any notice, but if you point at him and whisper, “Look, there is an iguana,” he will run away at once. An iguana never runs more than about fifty yards at a time; he then stops to get his breath. If you find him again he will be killed easily, as he cannot run so far a second time; there is, therefore, a second saying amongst the hunters that “A first run is a run for life, and when you are in danger you should run as far as you can before you stop to rest, as when you run the second time you will not be able to go so far.”
