The sun was high above the mangroves when Walthew joined Grahame and Macallister at breakfast the morning after they landed the rifles. No wind entered the gap in the forest, the smoke went straight up from the slanted funnel, and the air was still and sour. The steamer lay nearly dry among banks of mire, though a narrow strip of dazzling water sluggishly flowed inland past her. Fifty yards outshore, there was a broader channel and beyond it the dingy, pale-stemmed mangroves rose like a wall. Some were strangely spotted, and Walthew glanced at them with disgust as he drank his coffee.

"I guess I've never seen such repulsive trees," he said. "This place takes away one's appetite. Even the coffee's bitter; you've been doctoring it."

"It's weel to take precautions," Macallister replied. "Ye got a few nibbles last night from a dangerous bit beastie they ca' anopheles."

"I suppose it doesn't manufacture the malaria germ, and from the looks of the place one wouldn't imagine there was anybody else about for it to bite."

"That's what we're hoping. We're no' anxious for visitors, but when ye meet a smell like what we noo enjoy, ye take quinine till it makes ye hear church bells ringing in your head."

Walthew turned to Grahame.

"Can you get her off?"

"We'll try. The sooner we get out the better; but the tides are falling."

"Do you reckon the half-breed pilot meant to pile her up?"

"No," said Grahame thoughtfully. "For one thing, it would be a dangerous game, because his employers wouldn't hesitate about knifing him. They gave us a check which I've reason to believe will be honored and they wouldn't have wasted their money if they'd meant treachery. I imagine they're all too deep in the plot to turn informer."

"Do you think the pilot will turn up to take us out then?"

"I believe he'll be here at high-water, unless he's prevented."

"What could prevent him?"

"It's possible that our friends have been followed by the opposition's spies. The man who rules this country is not a fool."

"Then it seems to me we must do our best to heave the boat off this tide."

"Mack and I agree with you," Grahame said meaningly.

Breakfast was soon finished, for nobody had much appetite, and they sat, smoking, in the thin shade while the water got deeper in the creek. When the Enchantress slowly rose upright, Macallister went down to stir the fires; but though the others listened anxiously no splash of paddles broke the silence."Our pilot's not coming," Grahame said at last. "I'll try to take her out if we can get her afloat."

"What's likely to happen to him if he's been corralled by the dictator's rural-guards?"

"On the whole," said Grahame, "I'd rather not speculate. They have a drastic way of dealing with rebels here."

An hour later the screw shook the vessel, while the windlass strained at the cable. Once or twice a few links of chain ran in and she moved, but the mud had a firm hold and she stuck fast again. Then the water began to fall and Grahame reluctantly told Macallister to draw the fires.

"We're here for the next six days," he said.

"It's to be hoped the Government's spies don't find us out before we get her off," Walthew remarked.

"We could put the coal and heavier stores ashore, if ye can find a bit dry beach to land them on," Macallister suggested. "It would lighten her."

"I thought of that," Grahame answered. "On the other hand, it might be safer to keep them on board as long as possible. We could strip her and land everything in a day."

Macallister agreed, and for four days they lounged in such shade as they could find. It was fiercely hot, not a breath of wind touched the dazzling creek, and the sun burned through the awning. The pitch bubbled up from the deck-seams, the water in the tanks was warm, and innumerable flies came off from the mangroves and bit the panting men. To make things worse, there was no coolness after sunset, when steamy mist wrapped the vessel in its folds, bloodthirsty mosquitos came down in swarms, buzzing insects dimmed the lamps, and the smell of festering mire grew nauseating. Sleep was out of the question, and when the mosquitos drove them off the deck the men lay in their stifling berths and waited drearily for another day of misery to begin.

Among other discomforts, Walthew, who was not seasoned to the climate, was troubled by a bad headache and pains in his limbs, but he said nothing about this and accompanied Grahame when the latter took the soundings in the dinghy. At last they rose at daybreak one morning to lighten the vessel, and although he felt shaky and suffered from a burning thirst, Walthew took charge of the gig, which was to be used for landing coal.

The work was hard, for when they reached a sand bar up the creek they were forced to wade some distance through mud and shallow water with the heavy bags on their backs, while the perspiration soaked their thin clothes and the black dust worked through to their skin. At noon they stopped for half an hour and Walthew lay in the stern-sheets of the gig where there was a patch of shade. He could not eat, and after drinking some tea tried to smoke, but the tobacco tasted rank and he put his pipe away. Up to the present his life had been luxurious. He had been indulged and waited on, and had exerted himself only in outdoor sports. Now he felt very sick and worn out, but knew that he must make good. Having declined to enter his father's business, he must prove his capacity for the career he had chosen. Moreover, he suspected that Macallister and Grahame were watching him.

When the clatter of the winch began again he hid the effort it cost him to resume his task and stubbornly pulled his oar as the gig floated up the creek with her gunwale near awash. His back hurt him almost unbearably when he lifted a heavy bag, and it was hard to keep upon his feet while he floundered through the mire. Sometimes his head reeled and he could scarcely see. The blisters on his hands had worked into bleeding sores. This, however, did not matter much by comparison with the pain in his head.

After the coal was landed they loaded loose ironwork and towed heavy spars ashore, and Walthew held out somehow until darkness fell, when he paddled back to the Enchantress with a swarm of mosquitos buzzing round his face.

He could not eat when they sat down to a frugal meal, and afterward lay in his berth unable to sleep, and yet not quite awake, lost in confused thoughts that broke off and left him conscious of intolerable heat and pain. When he went languidly on deck the next morning Grahame looked hard at him.

"You had better lie down in the shade," he said.

"I may let up when we reach open water," Walthew answered with a feeble smile. "There's not much enjoyment to be got out of a lay-off here."

Grahame reluctantly agreed. He knew something about malaria and Walthew did not look fit for work; but every man was needed, and this foul swamp was no place to be ill. The sooner they got out the better.

Steam was up when the Enchantress rose with the tide, and shortly afterward the engines began to throb. Muddy foam leaped about the whirling screw, flame mingled with the smoke that poured from her funnel, and steam roared from the blow-off pipe. Then the clatter of winch and windlass joined in, and Grahame stood, tense and anxious, holding a rope that slipped round the spinning drum. The winch could not shorten it, though the vessel was shaking and working in her muddy bed. It was high-water, the tide would soon begin to fall, and the sweat of suspense and strain dripped from the man as, at the risk of breaking the warp, he tightened the turns on the drum. It gripped; to his surprise, a little slack came off, and he nodded to Walthew, who was watching him eagerly from the windlass.

"Give her all, if you burst the chain!" he cried.

The windlass clanked for a few moments, stopped, and clanked again; the Enchantress trembled and crept a foot or two ahead. Then she stuck while the cable rose from the water, rigid as a bar, and the messenger-chain that drove the windlass creaked and strained at breaking tension. While Grahame expected to see links and gear-wheels fly, there was a long shiver through the vessel's frame, a mad rattle of liberated machinery, and she leaped ahead.

Five minutes later Walthew walked shakily aft, scarcely seeing where he went because a confused sense of triumph had brought a mist into his dazzled eyes. This was the first big thing in which he had taken a leading part. He had made good and played the man; but there was still much to be done and he pulled himself together as he stopped near Grahame.

"She's moored where she won't ground again, but perhaps you had better see that the chain-compressors and warp fastenings are right."

"If you're satisfied, it's enough," said Grahame.

"Then I'll take the gig and get the coal on board."

"If you feel equal to it," Grahame answered.Walthew got into the boat with a sense of elation. His eyes had met Grahame's while they spoke, and a pledge of mutual respect and trust had passed between them. But this was not quite all. He felt he had won official recognition from a leader he admired; he was no longer on trial but accepted as a comrade and equal. The thought sustained him through a day of murderous toil, during which his worn-out muscles needed constant spurring by the unconquered mind. It was not dainty and, in a sense, not heroic work in which he was engaged, but it must be done, and he dimly saw that human nature rose highest in a grapple with obstacles that seemed too great to overcome. Whatever the odds against him were, he must not be beaten.

The heat was pitiless in the afternoon, but Walthew pulled his oar and carried the hundred-pound coal bags across a stretch of mire that grew broader as the tide ebbed. He could scarcely pull his feet out and keep the load upon his aching back, and he sometimes sank knee-deep in the softer spots. The air was heavy with exhalations from the swamps; he had thrown off his jacket and the coal wore holes in his shirt and rubbed raw places on his skin. He was wet from the waist downward and black above, while the gritty dust filled his eyes and nostrils. Still he held out until the work was finished, when the Enchantress's cargo-light began to twinkle through the dusk; and then, losing his balance, he fell forward into the boat with his last heavy load. Miguel pushed her off, and with oars splashing slackly she moved downstream. When she ran alongside the steamer, Grahame saw a limp, black figure lying huddled on the floorings. The others lifted it gently, but Walthew did not speak when he was laid on deck, and Macallister, bending over him, looked up at Grahame.

"Fever and exhaustion! I allow that ye were right about the lad. But we must do the best we can for him."

They washed off the coal-dust, and when Walthew, wrapped in thick blankets, lay unconscious in his berth, they debated earnestly over the medicine chest before administering a dose that experience in the unhealthy swamps of the tropics alone justified. They forced it, drop by drop, between his clenched teeth, and then Macallister waited with a grimy finger on his pulse, while Grahame sat down limply on the edge of the berth. His hands were bruised, his thin clothes were torn, and he felt the reaction after the day's strain. He had now an hour or two in which to rest, and then he must pull himself together to take the vessel down the creek.

When at last Macallister nodded, as if satisfied, Grahame went wearily up on deck. Except for a faint hiss of steam, everything was quiet. Tired men lay motionless about the deck, and the mist that clung to the mangroves did not stir. After a while the lap of the flood-tide against the planks made itself heard, and the moon, which was getting large, rose above the trees.

Grahame, sitting limply on the grating, half dozing while he waited, suddenly jumped to his feet, startled. Out of the semi-darkness came distinctly the splash of oars, faint at first and then nearer.

Miguel lay nearest him. The Spaniard, quickly grasping the danger, shook his men awake while Grahame ran below to Macallister.

"The government spies!" he said briefly. "Our pilot's turned traitor!"
