If a line be drawn between Jaluit, in the Marshall Group, and Bougainville, in the Solomons, and if this line be bisected at two degrees south of the equator by a line drawn from Ukuor, in the Carolines, the high island of Fuatino will be raised in that sun-washed stretch of lonely sea. Inhabited by a stock kindred to the Hawaiian, the Samoan, the Tahitian, and the Maori, Fuatino becomes the apex of the wedge driven by Polynesia far to the west and in between Melanesia and Micronesia. And it was Fuatino that David Grief raised next morning, two miles to the east and in direct line with the rising sun. The same whisper of a breeze held, and the Rattler slid through the smooth sea at a rate that would have been eminently proper for an island schooner had the breeze been thrice as strong.

Fuatino was nothing else than an ancient crater, thrust upward from the sea-bottom by some primordial cataclysm. The western portion, broken and crumbled to sea level, was the entrance to the crater itself, which constituted the harbour. Thus, Fuatino was like a rugged horseshoe, the heel pointing to the west. And into the opening at the heel the Rattler steered. Captain Glass, binoculars in hand and peering at the chart made by himself, which was spread on top the cabin, straightened up with an expression on his face that was half alarm, half resignation.

“It's coming,” he said. “Fever. It wasn't due till to-morrow. It always hits me hard, Mr. Grief. In five minutes I'll be off my head. You'll have to con the schooner in. Boy! Get my bunk ready! Plenty of blankets! Fill that hot-water bottle! It's so calm, Mr. Grief, that I think you can pass the big patch without warping. Take the leading wind and shoot her. She's the only craft in the South Pacific that can do it, and I know you know the trick. You can scrape the Big Rock by just watching out for the main boom.”

He had talked rapidly, almost like a drunken man, as his reeling brain battled with the rising shock of the malarial stroke. When he stumbled toward the companionway, his face was purpling and mottling as if attacked by some monstrous inflammation or decay. His eyes were setting in a glassy bulge, his hands shaking, his teeth clicking in the spasms of chill.

“Two hours to get the sweat,” he chattered with a ghastly grin. “And a couple more and I'll be all right. I know the damned thing to the last minute it runs its course. Y-y-you t-t-take ch-ch-ch-ch——”

His voice faded away in a weak stutter as he collapsed down into the cabin and his employer took charge. The Rattler was just entering the passage. The heels of the horseshoe island were two huge mountains of rock a thousand feet high, each almost broken off from the mainland and connected with it by a low and narrow peninsula. Between the heels was a half-mile stretch, all but blocked by a reef of coral extending across from the south heel. The passage, which Captain Glass had called a crevice, twisted into this reef, curved directly to the north heel, and ran along the base of the perpendicular rock. At this point, with the main-boom almost grazing the rock on the port side, Grief, peering down on the starboard side, could see bottom less than two fathoms beneath and shoaling steeply. With a whaleboat towing for steerage and as a precaution against back-draughts from the cliff, and taking advantage of a fan of breeze, he shook the Rattler full into it and glided by the big coral patch without warping. As it was, he just scraped, but so softly as not to start the copper.

The harbour of Fuatino opened before him. It was a circular sheet of water, five miles in diameter, rimmed with white coral beaches, from which the verdure-clad slopes rose swiftly to the frowning crater walls. The crests of the walls were saw-toothed, volcanic peaks, capped and halo'd with captive trade-wind clouds. Every nook and crevice of the disintegrating lava gave foothold to creeping, climbing vines and trees—a green foam of vegetation. Thin streams of water, that were mere films of mist, swayed and undulated downward in sheer descents of hundreds of feet. And to complete the magic of the place, the warm, moist air was heavy with the perfume of the yellow-blossomed cassi.

Fanning along against light, vagrant airs, the Rattler worked in. Calling the whale-boat on board, Grief searched out the shore with his binoculars. There was no life. In the hot blaze of tropic sun the place slept. There was no sign of welcome. Up the beach, on the north shore, where the fringe of cocoanut palms concealed the village, he could see the black bows of the canoes in the canoe-houses. On the beach, on even keel, rested the strange schooner. Nothing moved on board of her or around her. Not until the beach lay fifty yards away did Grief let go the anchor in forty fathoms. Out in the middle, long years before, he had sounded three hundred fathoms without reaching bottom, which was to be expected of a healthy crater-pit like Fuatino. As the chain roared and surged through the hawse-pipe he noticed a number of native women, lusciously large as only those of Polynesia are, in flowing ahu's, flower-crowned, stream out on the deck of the schooner on the beach. Also, and what they did not see, he saw from the galley the squat figure of a man steal for'ard, drop to the sand, and dive into the green screen of bush.

While the sails were furled and gasketed, awnings stretched, and sheets and tackles coiled harbour fashion, David Grief paced the deck and looked vainly for a flutter of life elsewhere than on the strange schooner. Once, beyond any doubt, he heard the distant crack of a rifle in the direction of the Big Rock. There were no further shots, and he thought of it as some hunter shooting a wild goat.

At the end of another hour Captain Glass, under a mountain of blankets, had ceased shivering and was in the inferno of a profound sweat.
