One alone seems interested in the diver's movements: his mate, a fair-skinned woman, with streaming blue-black hair, leans over the gunwale of the canoe, looking down through a kerosene tin water-glass.
The diver's dark figure against the pale-green coral becomes more blurred; a stream of silver air bubbles floats upward. Three minutes by the watch have come and gone. To the landsman it seems incredible; and even then there is no haste, no shooting to the surface and gasps for breath.
The dark body becomes clearer in outline as it emerges from the depths, and slowly, quite slowly, floats upward until a jet-black head breaks water and the diver clings to the gunwale of the canoe, inhaling deep but unhurried breaths and exhaling with a long-drawn whistle peculiarly his own.
In what way this whistle helps matters it is impossible to say, but whether a habit, a pose, or an aid in the regaining of breath, it is universal throughout the Paumotus; so much so that a busy afternoon with the pearlers sounds more like a tin-whistle band than anything else.
With the people of the atolls the ability to remain under water for long periods is more than an art; it is second nature. Instinctively, they do just those things that make one breath suffice for three minutes and sometimes four.
Preparatory to a descent they do not take a deep breath and hold it until the surface is reached again. They fill their lungs with a normal amount of air, which lasts them about a minute and a half; the other minute and a half is occupied in its exhalation. Then, too, every movement below water is made with the utmost conservation of energy; yet a good diver can bring up a hundred and fifty kilos of shell in a day, which means in the neighbourhood of six hundred francs.
And it is just these same nimble francs that tempt the Paumotan to abase his talents, even as others are tempted the world over. For the sake of a few more shells, another cluster a little farther down, he remains below just that trifle longer than is good for him, and in time it tells. The eyes become bloodshot and start from the head, he goes deaf, or paralysis seizes him.
"But the women are the worst," a sun-baked trader informed me; "the worst or the best, as you like to put it," he added, grinning. "They'll go on till they burst, or pretty near it. Bargain-counter instinct, I guess. We call it the 'bends.'"
'"The bends?'"
"Yes, one of 'em goes down, and down; sees some more shell a bit lower, and some more a bit lower than that. Then she's reaching out for one last flutter at something like twenty fathoms when they get her the 'bends,' I mean. You can see her fighting against them, but it's no good; they bring her knees to her chin, and she can't straighten up, and she drops the last lot of shell she's gathered, and hates that worse than the 'bends'."
