a black shadow, darker than any cloud.
All night they watched the shadow grow, and when the morning came and the tropic dawn stepped suddenly up from the east, the light glinted on the unmistakable green of verdure.
With the help of the steady wind they drifted slowly closer and closer to the island. By noon they abandoned the timber and started swimming, but the submerged beach went out far more gradually than they had expected. The last hundred yards they walked arm in arm, floundering through the gentle surf.
Then they stumbled up the beach, reeling with weariness, and sprawled out in the shade of a palm tree. They were asleep almost before they struck the sand.
It was late afternoon when they woke, ravenously hungry, their throats burning with thirst. For food McTee climbed a coconut palm and knocked down some of the fruit. They split the gourds open on a rock, drank the liquor, and ate heartily of the meat. That quelled their appetites, but the sweet liquor only partially appeased their thirst, and they started to search the island for a spring. First they went to the center of the place to a small hill, and from the top of this they surveyed their domain. The island was not more than a thousand yards in width and three or four miles in length. Nowhere was there any sign of even a hut.
"Well?" queried Harrigan, seeing McTee frown.
"We can live here," explained the captain, "but God knows how long it will be before we sight a ship. Our only hope is for some tramp freighter that's trying to find a short cut through the reefs. Even if we sight a tramp, how'll we signal her?"
"With a fire."
"Aye, if one passes at night. We could stack up wood on the top of this hill. The island isn't charted. If a skipper saw a light, he might take a chance and send a boat. But how could we kindle a fire?"
They went slowly down the hill, their heads bent. At the base, as if placed in their path to cheer them in this moment of gloom, they found a spring. It ran a dozen feet and disappeared into a crevice. They cupped the water in their hands and drank long and deep. When they stood up again, McTee dropped a hand on Harrigan's shoulder. He said: "You've cause enough for hating me."
"Pal," said Harrigan, "you're nine parts devil, but the part of you that's a man makes up for all the rest."
McTee brooded: "Now we're standing on the rim of the world, and we've got to be brother to each other. But what if we get off the island—there's small chance of it, but what if we should? Would we remember then how we took hands in the trough of the sea?"
Harrigan raised his hand.
"So help me God—" he began.
"Wait!" broke in McTee. "Don't say it. Suppose we get off the island, and when we reach port find one thing which we both want. What then?"
Harrigan remembered a word from the Bible.
"I'll never covet one of your belongin's, McTee, an' I'll never cross your wishes."
"Your hair is red, Harrigan, and mine is black; your eye is blue and mine is black. We were made to want the same thing in different ways. I've never met my mate before. I can stand it here on the rim of the world—but in the world itself—what then, Harrigan?"
They stepped apart, and the glance of the black eye crossed that of the cold blue.
"Ah-h, McTee, are ye dark inside and out? Is the black av your eye the same as the soot in your heart?"
"Harrigan, you were born to fight and forget; I was born to fight and remember. Well, I take no oath, but here's my hand. It's better than the oath of most men."
"A strange fist," grinned Harrigan; "soft in the palm and hard over the knuckles—like mine."
They went down the hill toward the beach, Harrigan singing and McTee silent, with downward head. On the beach they started for some rocks which shelved out into the water, for it was possible that they might find some sort of shellfish on the rocks below the surface of the water. Before they reached the place, however, McTee stopped and pointed out across the waves. Some object tossed slowly up and down a short distance from the beach.
"From the wreck," said McTee. "I didn't think it would drift quite as fast as this."
They waded out to examine; the water was not over their waists when they reached it. They found a whole section from the side of the wheelhouse, the timbers intact.
On it lay Kate Malone, unconscious.
Manifestly she never could have kept on the big fragment during the night of the storm had it not been for a piece of stout twine with which she had tied her left wrist to a projecting bolt. She had wrapped the cord many times, but despite this it had worn away her skin and sunk deep in the flesh of her arm. Half her clothes were torn away as she had been thrown about on the boards. Whether from exhaustion or the pain of her cut wrist, she had fainted and evidently lain in this position for several hours; one side of her face was burned pink by the heat of the sun.
They dragged the float in, and McTee knelt beside the girl and pressed an ear against her breast.
"Living!" he announced. "Now we're three on the rim of the world."
"Which makes a crowd," grinned Harrigan.
CHAPTER 10
They started working eagerly to revive her. While McTee bathed her face and throat with handfuls of the sea water, Harrigan worked to liberate her from the twine. It was not easy. The twine was wet, and the knot held fast. Finally he gnawed it in two with his teeth. McTee, at the same time, elicited a faint moan. Her wrist was bruised and swollen rather than dangerously cut. Harrigan stuffed the twine into his hip pocket; then the two Adams carried their Eve to the shade of a tree and watched the color come back to her face by slow degrees.
The wind now increased suddenly as it had done on the evening of the wreck. It rose even as the day darkened, and in a moment it was rushing through the trees screaming in a constantly rising crescendo. The rain was coming, and against that tropical squall shelter was necessary.
The two men ran down the beach and returned dragging the ponderous section of the wheelhouse. They leaned the frame against two trunks at the same instant that the first big drops of rain rattled against it. Overhead they were quite securely protected by the dense and interweaving foliage of the two trees, but still the wind whistled in at either side and over and under the frame of boards. Of one accord they dropped beside their patient.
She was trembling violently; they heard the light, continuous chattering of her teeth. After her many hours under the merciless sun, this sudden change of temperature might bring on the fever against which they could not fight. They stripped off their shirts and wound them carefully around her shivering body. McTee lifted her in his arms and sat down with his back to the wind. Harrigan took a place beside him, and they caught her close. They seemed to be striving by the force of their will to drive the heat from their own blood into her trembling body. But still she moaned in her delirium, and the shivering would not stop.
Then the great idea came to Harrigan. He rose without a word and ran out into the rain to a fallen tree which must have been blown down years before, for now the trunk and the splintered stump were rotten to the core. He had noticed it that day. There was only a rim of firm wood left of the wreck. The stump gave readily enough under his pull. He ripped away long strips of the casing, bark and wood, and carried it back to the shelter. He made a second trip to secure a great armful of the powder-dry time-rotted core of the stump.
His third expedition carried him a little farther afield to a small sapling which he could barely make out through the night. He bent down the top of the little tree and snapped off about five feet of its length. This in turn he brought to the shelter. He stopped short here, frozen with amazement. The girl was raving in her delirium, and to soothe her, McTee was singing to her horrible sailor chanteys, pieced out with improvised and foolish words.
Harrigan listened only while his astonishment kept him helpless; then he took up his work. He first stripped away the twigs from his sapling top. Then he tied the twine firmly at either end of the stick, leaving the string loose. Next he fumbled among the mass of rubbish he had brought in from the rotten trunk and broke off a chunk of hard wood several inches in
