The night was hot and nearly calm, and Marston, sitting on the cabin skylight, languidly looked about. A Krooboy held the wheel, and his dark figure cut against the phosphorescent sea. Columbine's bulwarks were low and when she rolled the long, smooth swell ran level with their top. A dim glow came from the compass binnacle, but the schooner was close-hauled and the Kroo steered by the faint strain on the helm. The wind was light and baffling and Columbine beat against it as she worked along the coast.

She carried all her canvas and her high gaff-topsail swung rhythmically across the sky, shutting out the stars. Her dark mainsail looked very big and every now and then shook down a shower of dew as its slack curves swelled. A small moon touched the tops of the undulations with silver light, and when the bows went down the foam that leaped about the planks glimmered with green and gold. Booms and blocks rattled and timbers groaned.

Marston could not see the land, which was hidden by the sour, hot mist that at sunset rolls off the African coast. He did not want to see it; he hoped he had done with Africa, but he doubted. Columbine was on the track the keels of the old slavers plowed, and he felt that the shadow of the dark country might follow him across the sea. Long since, Africa had peopled South America and the West Indies; Wyndham's ancestors had helped in that. One found mangrove swamps, fever, and negro superstition on the Caribbean coast, and it was significant that Rupert Wyndham had vanished there. The trouble was Harry had inherited something of his uncle's temperament. All the same, Marston had undertaken to stand by him and meant to do so.

The breeze got lighter, the wet canvas flapped, and Columbine hardly made steerage way. She rolled until her bulwarks touched the water and threw off fiery foam. One could not stand on her slanted deck, and blocks and spars made a hideous din. In the distance, the roar of surf rose and fell with a measured beat. Somewhere in the mist the big combers crashed upon a hammered beach. It did not matter if there was wind or not; the white band of surf had fringed the coast since the world was young.

Marston found his watch dreary. There was nothing to do; nothing, that he could see, threatened, and the scattered light clouds hardly moved across the sky. He was filling his pipe when he heard a step and saw Wyndham by the wheel. He knew him by his white duck; the negro crew did not wear much clothes.

"Hallo!" he said. "My watch is not up."

"I was awake," Wyndham replied. "Felt I ought to get on deck. The glass is falling."

"Did you feel you ought to come after you noted this?"

"Before," said Wyndham, dryly. "I didn't know the glass had dropped until I got a light, but it looks as if I might have stayed below. However, since I have turned out, we'll haul down the main-topsail."

He gave an order and two Krooboys got to work. There was no obvious reason for lowering the sail, but when Wyndham ordered the negroes obeyed. Although they grinned with frank good-humor when Marston talked to them, he knew he did not share Wyndham's authority. Yet Harry was not harsh.

When the sail was lowered Wyndham looked about. Some of the scattered clouds had rolled together and the sky was black over the land. One could scarcely feel the light wind, but the surf had got louder. Its roar came out of the dark as if heavy trains were running along the coast.

"It looks ridiculous, particularly since I'd like to edge her farther off the beach, but I think we'll stow the mainsail and fore-staysail," Wyndham remarked.

Marston agreed. Although he could see no grounds for shortening sail, he trusted Wyndham's judgment, and the Krooboys got to work again. The ropes, however, were stiff and swollen with the dew, and the mainsail came down slowly. The heavy folds of canvas caught between the topping-lifts; the gaff-jaws jambed on the mast. Wyndham sent a man aloft to sit upon and ride down the spar, but this did not help much, and the boom along the foot of the sail lurched with violent jerks. Blocks banged and loose ropes whipped across the deck. The sweat ran down Marston's face; he wanted to finish the job. For one thing, Columbine was unmanageable while the half-lowered canvas flapped about.

Stopping a moment for breath, he glanced over the rail. The long swell sparkled with small points of light that coalesced in sheets of green flame when the undulations broke against the schooner's side. The deck was spangled with luminous patches by the splashes and the wake that trailed astern was bright. Columbine stole through the water although the wind had nearly gone. It was not worth while to bring her head-to when they shortened sail.

Then the helmsman shouted and Marston felt one side of his face and body cool. The loose canvas flapped noisily. Its folds shook out and swelled, and Marston seized a rope. His skin prickled; he felt a strange tension and a feverish desire to drag down the sticking gaff. A few moments afterwards, something flickered behind the sail and a peal of thunder drowned the noise on board. When it died away, rolling hull, slanted masts, and the figures of the men stood out, wonderfully sharp, against a dazzling blaze that vanished and left bewildering dark. The next peal of thunder deafened Marston, who thought Wyndham shouted but heard no words. This did not matter, because he knew they must secure the sail before the tornado broke, and he pulled at the downhaul. He could not hear the wind for the thunder, but it had begun to blow.

The sail swelled between the confining ropes, there was a noise on one side of the yacht, water foamed along the planks, and she began to swing. It looked as if the steersman were putting up the helm. The peak of the gaff was nearly down; with another good pull they could seize it and lash it to the boom. Then a dazzling flash touched the deck. Marston saw Wyndham run aft and push the Kroo from the wheel, but this was the last he saw clearly for sometime. He imagined the fellow had meant to run the yacht off before the squall; one could ease the strain of a sudden blast like that, but if the squall lasted, they could not shorten sail while she was before the wind. Now she was coming round. Wyndham had put the helm down. It looked as if he were too late.

The tornado broke upon her side and she went over until her lee rail was in the sea. There was a noise like a thunder-clap forward as a sail blew away; Marston thought it was the jib. He could see nothing. It had got impenetrably dark, but he had a vague notion that water rushed along the deck and the mainsail had broken loose and blown out between the ropes. Unless they could master it, the mast would go. He heard another report forward and thought somebody had loosed the staysail halyards and the sail had blown to rags. Although his eyes were useless, he knew what was going on.

But they must secure the main gaff, and clutching at the boom above his head, he swung himself up and worked along to its outer end, which stretched over the stern. A footrope ran below the spar; one could balance oneself by its help and he vaguely distinguished somebody close by. It was, no doubt, Wyndham, because his clothes looked white. There was no use in shouting. The uproar drowned one's voice; besides, their job was plain. They must get a rope round the end of the gaff and lash it fast.

Marston's waist was on the boom; his feet stuck out behind him, braced against the rope. In front there was a dark gulf. This was, no doubt, the hollow of the sail, and the indistinct slanting line above was the gaff. He threw a rope across the latter, but the end did not drop, so that he could seize it under the sail; the wind blew it out, straight and tight. He tried again, farther aft, jostling against the figure that looked faintly white, and leaning down across the boom, caught the end of the rope. The other man helped him and when they had got a loop round the end of the gaff he stopped for breath. He was shaky after the effort, his heart thumped painfully, and his chest rose and fell. He imagined other men were on the boom, but he and his companion were all that mattered. They must lash the peak down before the sail blew out again. When this was done, the others could master the distended folds.

The wet rope tore his hands; he felt them get slippery with blood, but he held on and the man beside him helped. Marston knew he was not a Kroo. The Kroos were bold sailors, but their resolution had a limit. When a job looked hopeless they gave up; the man beside Marston was another type. While there was breath in his body he would stick to his task. The sail must be conquered.

Lightning played about them and Marston's eyes were dazzled by the changes from intolerable glare to dark. He trusted to the feel of things and his seaman's knowledge of what was happening. He did not think, but worked half-consciously. They made the gaff fast, and then something broke and the heavy boom swung out over the sea. The jerk threw Marston's feet from the rope and his body began to slip off the boom. He saw fiery foam below, but as he braced himself for the plunge the next man seized him. It looked as if they must both slip off, for Marston found no hold for his hands on the smooth, wet spar. Perhaps the pressure of the wind saved them by forcing their limp bodies against the boom, for the other man steadied Marston until his foot touched the rope again.

For a moment or two they hung on, not daring to move and waiting until they gathered strength. Then they carefully worked their way to the inner end of the spar and dropped, exhausted, on the deck. There was however, no rest for them. The massive boom must be dragged back and dropped into its crutch. It could not be left to lurch about and smash all it struck. Marston was vaguely conscious that a gang of Krooboys ran to the mainsheet and Wyndham directed their efforts. He, himself, could do no more, and he leaned against the rail, breathing hard.

As his exhaustion vanished he began to note things. The men had secured the boom; but the schooner's bows looked bare and he remembered the jibs had blown away. The foresail was torn and half-lowered, and the gaff at its head was jambed. The torn canvas kept the vessel from falling off the wind, but would not bring her up enough for her to lie to. Masts and deck were horribly slanted, the windward bulwark was hove high up, and luminous spray drove across its top. It looked as if she were going over and there was an appalling din, for the scream of the tornado pierced the thunder.

Then lightning enveloped the yacht and ran along the water. For an instant Marston saw Wyndham's white figure at the wheel, and then he groped his way towards him in the puzzling dark. Harry would need help, for Marston knew what he meant to do. Since Columbine would not come up, he was going to run her off before the wind in order to ease the horrible pressure that bore her down. The trouble was, the tornado blew from sea, and land was near. Marston seized the wheel, and using all his strength, helped Wyndham to pull it round. She felt her rudder and began to swing, lifting her lee rail out of the water. Then she came nearly upright with a jerk, and although the tornado was deafening, Marston thought he heard the water roar as it leaped against her bows.

The speed she made lifted her forward and a white wave curled abreast of the rigging. She was going like a train and Marston sweated and gasped as he helped at the wheel. There was nothing to do but let her run, although it was obvious she could not run long. A glance at the lighted compass indicated that she was heading for the land, where angry surf beat upon an inhospitable beach. If they tried to bring her round, the masts would go and she might capsize.

She drove on and presently the thunder stopped. Rain that fell in sheets swept the deck and beat their clothes against their skin. One heard nothing but the roar of the deluge and the darkness could not be pierced. After a few minutes Marston felt the strain on the wheel get easier and lost the sense of speed. The deck did not seem to be lifted forward and he thought the bows had resumed their proper level. When he turned his head the rain no longer lashed his face, the foresail flapped, and the straining, rattling noises began again. It looked as if the wind had suddenly got light.

"Let's bring her round," he shouted and heard his voice hoarse and loud.

Wyndham signed agreement, they turned the wheel, and the crew ran about the deck. She came round and a few minutes afterwards headed out to sea, lurching slowly across the swell that now rolled and broke with crests of foam. The sky had cleared, but not far off an ominous rumble came out of the gloom astern.

"We'll wait for daybreak before we make sail," Wyndham remarked. "You can get below. My watch has begun."

"I suppose you were with me on the boom?"

"I was on the boom," said Wyndham. "Somebody else was near."

"Do you imply you didn't know whom it was when you held me up?"

"Oh, well," said Wyndham, laughing, "it's not important. Suppose I had grabbed a Krooboy who was falling? Do you imagine I ought to have let him go? Anyhow, we helped each other. I don't expect I'd have reached the deck if I had been alone."

Marston said no more. One felt some reserve when one talked about things like that. He looked to windward, and seeing the night was calm, went below.

CHAPTER VI
THE MIDDLE PASSAGE

Marston lounged with languid satisfaction on a locker in the stern cabin. He had borne some strain and his body felt strangely slack although his brain was active. The cabin was small and very plain, because the yacht had been altered below decks when she was fitted for carrying cargo. Moisture trickled down the matchboarded ceiling, big warm drops fell from the beams, and a brass lamp swung about as she rolled. Marston, however, knew this was an illusion; the beams moved but the lamp was still.

There were confused noises. Water washed about inside the lurching hull, although a sharp clank overhead indicated that somebody was occupied at the pump; water gurgled, with a noise like rolling gravel, outside the planks. Timbers groaned, a seam in the matchboarding opened and shut, and a dull concussion shook the boat when her bows plunged into the swell. The swell was high, although the wind had dropped. Marston knew these noises and found them soothing. They belonged to the sea, and he loved the sea, although he had not long since fought it for his life. Now the strain was over, he felt the struggle with the tornado had braced and steadied him.

In the tropics, it was the land he did not like. Perhaps he was getting morbid, for after all he had not seen much of the African coast and yet it frankly daunted him. His confused recollections were like a bad dream; muddy lagoons surrounded by dreary mangroves from which the miasma stole at night, hot and steamy forests where mysterious dangers lurked, and rotting damp factories from which the burning sun could not drive the shadow that weighed the white man down. Marston was not imaginative, but he had felt the gloom.

He pondered about it curiously. The shadow was, so to speak, impalpable; vague yet sinister. Now and then white men rebelled against it with noisy revels, but when the liquor was out the gloom crept back and some drank again until they died. Yet the coast had a subtle charm, against which it was prudent to steel oneself. The shadow was a reflection of the deeper gloom in which the naked bushmen moved and served the powers that rule the dark.

Fever-worn traders declared there were such powers. One heard strange stories that the men who told them obviously believed. It looked as if the Ju-Ju magicians were not altogether impostors; they knew things the white man did not and by this knowledge ruled. Their rule was owned and firm. Marston had thought it ridiculous, but now he doubted. There was something behind the hocus-pocus; something that moved one's curiosity and tempted one to rash experiment. Marston knew this was what he feared. Harry was rash and had rather felt the fascination than the gloom.

Marston banished his disturbing thoughts and began to muse about their struggle with the sail. Harry was a normal, healthy white man then. It was rather his sailor's instincts than conscious resolution that led him to keep up the fight when it looked as if he must be thrown off the boom. He would have been thrown off before he owned he was beaten. One did things like that at sea, because they must be done, and did not think them fine. Marston reviewed the fight, remembering his terror when he slipped and how his confidence returned after Harry seized his arm. The thought of the lonely plunge had daunted him; it was different when he knew he would not plunge alone. If Harry and he could not reach the deck, they would drop into the dark together. That was all, but it meant much. For one thing, it meant that Marston must go where his comrade went, although he might not like the path. In the meantime he was tired and got into his bunk.

When he went on deck in the morning the breeze was fresh and Columbine drove through the water under all plain sail, for they had some spare canvas on board. The sky was clear and the sun sparkled on the foam that leaped about the bows and ran astern in a broad white wake. The old boat was fast and there was something exhilarating in her buoyant lift and roll. Marston and Wyndham got breakfast under an awning on deck. Wyndham wore thin white clothes and a silk belt. His skin was burned a dark red and his keen blue eyes sparkled. One saw the graceful lines of his muscular figure; he looked alert and virile.

"You're fresh enough this morning," Marston remarked. "My back is sore and my arms ache. It was a pretty big strain to secure the gaff."

Wyndham laughed. "If the sail had blown away from us, the mast would have gone and the boat have drifted into the surf."

"I suppose we knew this unconsciously. Anyhow, I didn't argue about the thing."

"You held on," said Wyndham. "Well, I expect it's an example of an instinct men developed when they used the old sailing ships. They must beat the sea or drown, and sometimes the safety of all depended on the nerve of one. I expect it led to a kind of class-conscientiousness. The common need produced a code."

"The instinct's good. Somehow, all you learn at sea is good; I mean, it's morally bracing."

Wyndham smiled and indicated a faint dark line that melted into the horizon on the starboard hand.

"It's different in Africa, for example?"

"Oh, well," said Marston cautiously, "Africa has drawbacks, but if you don't get fever and are satisfied to look at things on the surface, you might stay there sometime and not get much harm."

Wyndham saw Marston meant to warn him and was amused. Bob was rather obvious, but he was sincere.

"Suppose you're not satisfied with things as they look on the surface and want to find out what they are beneath?" he asked.

"Then I think you ought to clear out and go back to the North."

"A simple plan! As a rule, your plans are simple. I'm curious, however, and sometimes like to indulge my curiosity. It's easily excited in Africa. There is much the white man doesn't know; he's hardly begun to grasp the negro's point of view."

"The negro has no point of view. He gropes in the dark."

"I doubt it," said Wyndham thoughtfully. "I rather imagine he sees a light, but perhaps not the light we know. There's a rude order in his country and men with knowledge rule. The Leopards, the Ghost Crocodiles, and the other strange societies don't hold power for nothing. Power that's felt has some foundation."

"You like power," Marston remarked.

Wyndham smiled and looked about while he felt for another cigarette. Columbine, swaying rhythmically to the heave of the swell, drove through the sparkling water with a shower of spray blowing across her weather bow. Her tall canvas gleamed against the blue sky. A Krooboy lounged at the wheel, the most part of his muscular body naked and a broad blue stripe running down his forehead. Two or three more squatted in the shade of a sail. At the galley door the cook sang a monotonous African song. The wire shrouds hummed like harpstrings, striking notes that changed with the tension as the vessel rolled. There was nothing to do but lounge and talk and Wyndham's mood was confidential.

"I have not known much power," he said. "In England, power must be bought. My father was poor but careless; my mother was sternly conventional. When he died she tried to turn my feet into the regular, beaten path. I know now she was afraid I would follow my ancestors' wandering steps. Well, at school, I had the smallest allowance among the boys, and learned to plot for things my comrades enjoyed. As a rule, I got the things. I don't know if the effort was good or not, but I was ambitious and wanted a leading place. Folks like you don't know what it costs to hold one's ground."

"I expect I got things easily," Marston agreed. "Perhaps this was lucky, because I've no particular talent."

"You have one talent that is worth all mine," Wyndham rejoined with some feeling. "People trust you, Bob."

Marston colored, but Wyndham went on: "When I left school and went to Wyndhams' there was not much change. For the most part, my friends were rich, and I had a clerk's pay, with a vague understanding that at some far off time I might be the head of the house. The house was obviously tottering; I did not think it would stand until I got control. My uncle, Rupert's brother, would not see. Wyndhams' had stood so long he felt it was self-supporting and would stand. Well, he was kind, and I'm glad he died without knowing how near we really were to a fall.

"However, I didn't mean to talk about the house, but rather about my life when I was a shipping clerk. I had ambition and thought I had talent; I hated to be left behind by my friends. It cost much planning to share their amusements, join a good yacht club, and race my boat. Sportsmen like you don't know the small tricks and shabbiness we others are forced to use. Well, at length my uncle died and I got control of the falling house, with its load of debt. I'd long been rash, but the rashest thing I did was when I fell in love with Flora. Yet she loved me, and Chisholm, with some reserves, has given his consent. I have got to satisfy him and with this in view, we're bound for the Caribbean on board a thirty-year-old yacht."

Marston thought Wyndham did not look daunted. In a sense, his venture was reckless, but Harry tried, and did, things others thought beyond their powers. On the whole Marston imagined his boldness was justified.

"If money can help, you know where it can be got," he said.

Wyndham's half-ironical glance softened.

"Thanks, Bob! So far, I haven't gone begging from my friends; but if I can use your money without much risk, I will borrow. I think you know this."

"What's mine is yours," Marston remarked and went to the cabin for a chart, with which he occupied himself.

He studied the chart and sailing directions when he had nothing to do and was rather surprised that Wyndham did not. It was a long run to the Caribbean and would be longer if they drifted into the equatorial calms. Marston had a yacht master's certificate, although he was rather a seaman than a navigator. He could find his way along the coast by compass and patent-log, but to steer an ocean course was another thing. One must be exact when one calculated one's position by the height of the sun and stars.

For some time they made good progress and then the light wind dropped and Columbine rolled about in a glassy calm. The swell ran in long undulations that shone with reflected light, and there was no shade, for they lowered all sail to save the canvas from burning and chafing. The sun pierced the awning, and it was intolerably hot. They had reached the dangerous part of the old slavers' track; the belt of stagnant ocean where the south wind stopped and the north-east had not begun. The belt had been marked long since by horrors worse than wreck, for while the crowded brigs and schooners drifted under the burning sun, fresh water ran out and white men got crazed with rum while negroes died from thirst.

Wyndham lounged one morning under the awning after his bath. He wore silk pyjamas, a red silk belt, and a wide hat of double felt. He looked cool and Marston thought he harmonized with his surroundings; the background of dazzling water, the slanted masts that caught the light as they swung, and the oily black figures of the naked crew. He wondered whether Harry had inherited something from ancestors who had known the tragedies of the middle passage. Marston himself was wet with sweat, his eyes ached, and his head felt full of blood.

"We may drift about for some time," he said, throwing down a book he had tried to read. "The sailing directions indicate that the Trades are variable near their southern limit."

"It's a matter of luck," Wyndham agreed, and Marston started because his comrade's next remark chimed with his thoughts. "When I studied some of the house's old records I found that two of our brigs vanished in the calm belt. One wondered how they went. Fire perhaps, or the slaves broke the hatch at night. Can't you picture their pouring out like ants and bearing down the drunken crew? The crews did drink; slaving was not a business for sober men. Hogsheads of rum figure in our old victualing bills."

He paused and resumed with a hard smile: "Well, it was a devilish trade. One might speculate whether the responsibility died with the men engaged in it and vanished with the money they earned. None of the Wyndhams seem to have kept money long; luck went hard against them. When they did not squander, misfortune dogged the house."

"Superstition!" Marston exclaimed.

Wyndham laughed. "It's possible, but superstition's common and all men are not fools. I expect their fantastic imaginings hold a seed of truth. Perhaps somebody here and there finds the seed and makes it grow."

"In Africa, they water the soil with blood. It's not a white man's gardening." Marston rejoined and went forward to the bows, but got no comfort there.

The sea shone like polished steel, heaving in long folds without a wrinkle on its oily surface. But for the sluggish rise and fall, one might have imagined no wind had blown since the world was young.

For a week Columbine rolled about, and then one morning faint blue lines ran across the sea to the north. Gasping and sweating with the effort, they hoisted sail and sent up the biggest topsail drenched with salt water. Sometimes it and the light balloon jib filled and although the lower canvas would not draw, Columbine began to move. One could not feel her progress, there was no strain on the helm, but silky ripples left her side and slowly trailed astern.

For all that, she went the wrong way, heading south into the calm, and they could not bring her round. Her rudder had no grip when they turned the wheel, and sometimes she stopped for an hour and then crawled on again. The Krooboys panted in the shade of the shaking sails, and Marston groaned and swore when he took his glasses and slackly climbed the rigging. The dark-blue lines were plainer, three or four miles off, and he thought they marked the edge of the Trade-breeze.

Wyndham alone looked unmoved; he lay in a canvas chair under the awning, and smoked and seemed to dream. Marston wondered what he dreamed about and hoped it was Flora. In the afternoon Marston felt he must find some relief.

"I want to launch a boat and tow her," he said. "There's wind enough not far off to keep her steering."

Wyndham nodded. "Very well. It's recorded that they towed the Providence for three days and used up a dozen negroes in the boats, besides some gallons of rum. The fellow who kept the log was obviously methodical. However, I want to keep our boys, and you can't tow in the sun."

"It's unthinkable," Marston agreed. "We'll begin at dark."
