Austin went away, but it was almost daylight before sleep came to him, and he had only been on deck an hour when their guests departed in the morning. Jefferson, who bade them good-bye at the gangway, stood leaning on the rail while the pinnace steamed away, and then walked, with curious heaviness, towards his room. He crawled into his bunk when he reached it, and lay there, while Austin looked down on him with concern.

"I've had the fever on me for quite a while, and at last it has gripped me hard," he said. "I'll probably be raving in an hour or two. Get steam up as soon as you're able, and take her out of the devilish country."

Austin was very busy between his comrade's room, forecastle, and stoke-hold during the rest of that day, and he had very little time for rest at night, but though half the men were sick, and his own limbs were aching portentously, it was with a little thrill of exultation he climbed to the bridge early on the following morning. The windlass was rattling on the forecastle, Wall-eye stood by the winch astern, and the surfboat was sliding towards the mangroves, where a big wire hawser was made fast, in the rain. Austin was not a professional sailor, but he could handle surfboat and steam launch, and in the good days had sailed his yacht along the coast at home. He also had confidence in the grizzled, olive-faced Spaniard who stood gravely behind him, gripping the steering-wheel.

The anchor came home to the bows at last, somehow the fever-worn men on the forecastle hove it in; the after winch hammered when he made a sign, and the long, rusty hull moved backwards towards the forest as her head swung slowly round. There was a splash of dripping wire, and he swung up an arm with a cry of "Largo!"

Then the winch rattled furiously, a gong clanged below, and a wild, exultant shouting went up when the Cumbria's engines commenced to throb. The gaunt, hollow-faced men who stood, dripping, in the rain, had borne everything but cold, and now they were going home. Austin felt his eyes grow hazy for a moment as he leaned upon the rails, and then, with a little shake of his shoulders, he fixed his gaze steadily upon the mangroves that came sliding back to him ahead. He had, he felt, a task that would demand all his attention in front of him.

They slid down stream unchecked until the afternoon, and the Cumbria steered handily, which, since there were awkward bends to swing round, was fortunate for all of them; but Austin had misgivings when at last they approached one that appeared sharper than the rest, for he could only see the close ranks of dingy mangroves in front of him as he gazed into the rain and mist. The creek was too narrow to swing the steamer to an anchor, and it was evident that if she was to get around the bend at all he most go at it hard, for the yellow stream was running fast with them, and unless she steamed faster the vessel would not steer. He signed to the helmsman, who edged her in near one bank to gain a little room; and then set his lips tight as he clenched his telegraph and rang for full speed ahead. It was consoling to remember that Tom was below, for a good donkey-man is, as a rule, more to be trusted than a junior engineer.

Ahead, the oily current was sliding through the mangroves as well as among them, covering all their high-arched roots, and he knew that there were a good many feet of water there, for the creek was full, and he had heard of steamers going full tilt into the watery forest at such times. Still he breathed unevenly as he watched the dingy trees slide past one another, for the bend was opening very slowly, and there was a long tongue of mangroves close in front of him. The bridge planks were trembling beneath him now, and he could hear the thud-thud of the hard-driven screw; but the stream seemed to be running very fast at the bend, and, glancing round, he saw something very like fear in the face of the man who held the wheel. When he looked ahead again the long tongue of mangroves seemed flying towards him.

He strode to the end of the bridge and glanced down at the lift of rusty side. There was a good deal of it above the water, for the Cumbria was loaded easily, and she was also, he was very glad to remember, light of draught. He could not check her with an anchor under foot. She would only swing to it, and that would land her among the mangroves broadside on. If he backed his propeller he would as surely go ashore, and his face grew very grim as he made the helmsman a little sign. Since he must strike the forest, he would strike it fair, as hard as the engines could drive her, bows on; and he thrust down the telegraph once more for the last pound of steam.

The throb of plank and rail grew sharper, the trees seemed rushing at the forecastle, the helmsman gazed forward with drawn face over his moving wheel, and a shouting broke out on deck. Austin, however, did not move at all, save when he raised a hand to the helmsman. Once more, easy-going artist as he was, the Berserker fit was upon him, and it was with a light only one or two of his friends had ever seen there in his eyes he hurled her full speed at the forest.

She struck it, with a crash that flung two or three of the Spaniards staggering, and it crumpled up before her. Mangrove boughs came streaming down on her grinding forecastle, torn limbs clutched at rail and stanchion, and were smashed by them. Mire was whirled aloft by the thudding screw, and Austin, gripping his telegraph, laughed a harsh laugh as he saw that she was going through. How thick that belt of trees was, or what water flowed among their roots, he did not know, but he remembered that he had found no bottom among them in other places with a boathook, now and then.
