He checked her with a gesture of his hand. “I may be one of the first to leave. But I'll not rob any one else of his place in a boat or his space on one of those rafts. I'll swim for it.”

Slowly the land crept down upon the Doraine. The illusion was startling. The ship seemed to be lying absolutely motionless; it was the land that approached instead of the other way round. A thin white beach suddenly emerged from the green background to the left, to the right an ugly mass of rocks took shape, stretching as far as the eye could reach. Farther inland rose high, tree covered hills, green as emeralds in the blazing sunlight. On a sea of turquoise lolled the listless Doraine.

Soundings were taken from time to time. Even the bottom of the ocean was coming up to meet the Doraine. Its depth appreciably lessened with each successive measurement. From fifty fathoms it had decreased to ten since the first line was dropped.

At four o'clock, Captain Trigger ordered a boat lowered and manned by a picked crew in charge of the Second Engineer. The Doraine was about five miles off shore at the time, and was drifting with a noticeably increased speed directly toward the rock-bound coast. He had hoped she would go aground in the shallow waters off the sandy beach, but there was now no chance that such a piece of good fortune was in store for her. She was going straight for the huge black rocks.

The boat's crew rowed in for observations. Even before they returned to report, the anxious officers on board the vessel had made out a narrow fissure in the rocky coast line. They assumed that it was the mouth of a small river. The Second Engineer brought back the astonishing information that this opening in the coast was the gateway to a channel that in his judgment split the island into two distinct sections. That it was not the mouth of a river was made clear by the presence of a current so strong that his men had to exert themselves to the utmost to prevent the boat being literally sucked into the channel by the powerful tide, which apparently was at its full. This opening,—the water rushed into it so swiftly that he was satisfied it developed into a gorge farther back from the coast,—was approximately two hundred yards wide, flanked on either side by low lying, formidable bastions of rock. The water was not more than fifty feet deep off the entrance to the channel.

Gradually the prow of the Doraine swung around and pointed straight for the cleft in the shore. The ship, two miles out, had responded to the insidious pressure of the current and was being drawn toward the rocks,—at first so slowly that there was scarcely a ripple off her bows; then, as she lumbered onward, she began to turn over the water as a ploughshare turns over the land.

At precisely six o'clock she slid between the rocky portals and entered a canal so straight and true that it might have been drilled and blasted out of the earth under the direction of the most skilful engineers in the world.

Soundings were hastily taken. Discovering that the water was not deep enough even at high tide to submerge the vessel when the inevitable came to pass and she sank to the bottom, Captain Trigger renewed his efforts to release the anchor chains, which had been caught and jammed in the wreckage. He realized the vital necessity for checking the Doraine in her flight before she accomplished the miracle of passing unhindered through the channel and out into the open sea beyond. The swiftness of the current indicated plainly enough that this natural canal was of no great length.

The ship slid on between the tree lined banks. The trees were of the temperate zone, with spreading limbs, thick foliage and hardy trunks. There were no palms visible, but in the rarely occurring open spaces a large shrub abounded. This was instantly recognized by Percival, who proclaimed it to be the algaroba, a plant commonly found on the Gran Chaco in Argentina. While the woodland was thick there was nothing about it to suggest the tropical jungle with its impenetrable fastnesses.

The keel of the half-sunken Doraine was scraping ominously on the bed of the channel. She shivered and swerved from frequent contact with submerged rocks, but held her course with uncanny steadiness, while every soul on board gazed with stark, despairing eyes at the land which mocked them as they passed. Far on ahead loomed the lofty hills, and beyond them lay—What? The ocean?
