It seemed as if no one, whether ornithologist, evolutionist, poet or philosopher could fail to be profoundly impressed at the sight we had seen. Here I was in a very real, a very modern boat, with the honk of motor horns sounding from the river road a few yards away through the bushes, in the shade of this tropical vegetation in the year nineteen hundred and sixteen; and yet the curtain of the past had been lifted and I had been permitted a glimpse of what must have been common in the millions of years ago. It was a tremendous thing, a wonderful thing to have seen, and it seemed to dwarf all the strange sights which had come to me in all other parts of the earth's wilderness. I had read of these habits and had expected them, but like one's first sight of a volcano in eruption, no reading or description prepares one for the actual phenomenon.
I sat silently watching for the re-appearance of the young bird. We tallied five pairs of eyes and yet many minutes passed before I saw the same little head and emaciated neck sticking out of the water alongside a bit of drift rubbish. The only visible thing was the protruding spikes of the bedraggled tail feathers. I worked the boat in toward the bird, half-heartedly, for I had made up my mind that this particular brave little bit of atavism deserved his freedom, so splendidly had he fought for it among the pimplers. Soon he ducked forward, dived out of sight and came up twenty feet away among an inextricable tangle of vines. I sent a little cheer of well wishing after him and we salvaged Sam.
Then we shoved out the boat and watched from a distance. Five or six minutes passed and a skinny, crooked, two-fingered mitten of an arm reared upward out of the muddy flood and the nestling, black and glistening, hauled itself out of water.
Thus must the first amphibian have climbed into the thin air. But the young hoatzin neither gasped nor shivered, and seemed as self-possessed as if this was a common occurrence in its life. There was not the slightest doubt however, that this was its first introduction to water. Yet it had dived from a height of fifteen feet, about fifty times its own length, as cleanly as a seal leaps from a berg. It was as if a human child should dive two hundred feet!
In fifteen minutes more it had climbed high above the water, and with unerring accuracy directly toward its natal bundle of sticks overhead. The mother now came close, and with hoarse rasping notes and frantic heaves of tail and wings lent encouragement. Just before we paddled from sight, when the little fellow had reached his last rung, he partly opened his beak and gave a little falsetto cry,—a clear, high tone, tailing off into a guttural rasp. His splendid courage had broken at last; he had nearly reached the nest and he was aching to put aside all this terrible responsibility, this pitting of his tiny might against such fearful odds. He wanted to be a helpless nestling again, to crouch on the springy bed of twigs with a feather comforter over him and be stuffed at will with delectable pimpler pap. Such is the normal right destiny of a hoatzin chick, and the whee-og! wrung from him by the reaction of safety seemed to voice all this.

A WILDERNESS LABORATORY
Robinson Crusoe had a wreck well stored with supplies, and we inherited only four walls and a roof. Still, we had a boy Friday—Sam, an ebony Demeraran, exactly half of whose teeth had been lost in the only automobile ride he had ever taken. Sam was sent by some personal Providence—perhaps the god of intelligence bureaus—as the first of our faithful following in Guiana. Sam had formerly been a warden in the Georgetown jail, and rumor had it that he left because he saw "jumbies" in the court where one hundred and nine men had been hung. And surely that was where jumbies would be found if anywhere. Even Crusoe's man must have admitted that. How wardenship could be of aid to us in our scientific work was a puzzle.
Only once before did a servant's previous experience surpass this in utter uselessness. That was when a Russian chauffeur whom I had taken on trial found a cowboy saddle in my attic and seriously and proudly showed me in great detail, with the saddle strapped to the banisters, how with his long Cossack training he could stand on his neck when going at full speed! But Sam, like many another servant of the past, was to prove a treasure.
