Wednesday the Tenth by Grant Allen

Presently, as we headed towards the black object on the horizon, Nassaline stretched out that skinny finger of his once more (no amount of feeding ever seemed to make Nassaline one ounce fatter), and cried out in his shrill little piping voice, "Two man on the boat! him makey signs for call us!"

I'd give anything to have eyes as sharp as those Polynesians. I looked across the sea, and the loppy waves in the foreground, and could just make out with the naked eye that the row-boat had something that looked like a red handkerchief tied to her bare mast, and a white signal flapping in the wind below it; but not a living soul could I distinguish in her without my binocular. So I put up my glasses and looked again. Sure enough, there they were, two miserable objects, clinging as it seemed half-dead to the mast, and making most piteous signs with their hands to attract our attention. As soon as they saw that we had really sighted them, and were altering our course to pick them up, their joy and delight knew no bounds, as we judged. They flung up their arms ecstatically into the air, and then sank back, exhausted, as I guessed, on to the thwarts where they had long ceased sitting or rowing.
