dropped down stream and my notion is it was a relief to Wyndham the cablegram arrived. If it had not arrived, he would have stayed. He was that kind of man."
"Had you trouble afterwards?" Marston asked.
"I had not. It was as if a shadow had melted. The strain had gone."
"Then it looks as if my uncle, alone, were threatened." Wyndham remarked.
Ellams nodded. "Yes. I think it was, so to speak, a personal thing. For all that, our trade got slack and has not since touched the mark it reached in your uncle's time. Well, I think that's all, and perhaps I have talked too much."
"If you'll mix another cocktail, we'll go to bed," Wyndham replied and when, a few minutes afterwards, he went to his room stopped at the door.
"This is where Rupert Wyndham slept with the gun beside him, I suppose?" he said. "I wonder what he dreamed about!"
For some time Marston did not sleep. As a rule, he did not indulge his imagination, but he had been disturbed by the agent's tale and there were strange noises. Some he thought were made by cracking boards and falling damp; others puzzled him and he found them daunting in the dark. They were like footsteps, as if somebody stole about the rooms. Marston had had enough of Africa and yet he owned the country had a mysterious charm. White men stayed, knowing the risk they ran and without much hope of money reward, until they died of fever or their minds got deranged. The latter happened now and then. In order to keep sane, one must concentrate on one's business and refuse to speculate about the secret life of the bush. After all, there was much to speculate about —
Marston pulled himself up. He was a sober white man and had nothing to do with the negro's fantastic superstitions. Magic and witchcraft were ridiculous, but in a country where they were a ruling force it was not easy to laugh. He thought Rupert Wyndham had made rash experiments and had dared too much, and although this was perhaps not important, Harry had his uncle's temperament. The trouble was there. Still they would leave the river soon and it would be a relief to go to sea. The sea was clean and bracing.
Three or four days afterwards Columbine dropped down stream on the ebb. A big naked Krooboy held the wheel, another in the fore-channels swung the lead and called the depth in a musical voice. The white factory got indistinct and melted into the swamps, the puffs of wind were fresher, and Marston was conscious of a keen satisfaction as the dreary mangroves slipped astern and yellow sand and lines of foam came into view ahead.
Wyndham, smoking a cigarette, leaned against the rail. He wore white duck without a crease and a big pale-gray hat. Marston thought he looked very English, with his keen blue eyes, light hair, and red skin, but his gaze was contemplative.
"You're not sorry to get away?" he presently remarked. "I wonder whether Rupert Wyndham was."
"I wonder why he stayed," said Marston. "Unless, of course, he was earning money."
"A plausible explanation, but I'm not sure it's good," Wyndham replied with a smile. "The head of our house was often extravagant but never, I think, a miser. We're not a greedy lot."
"You were traders; the object of trading is to get rich."
"I doubt if this was my uncle's, or some of my other ancestors' object, I think they valued money for what it would buy. Anyhow, they seldom kept it long."
"Since most of us value money for what it will buy, I don't understand," Marston rejoined.
"You bought a country house, a sober sportsman's life, and the liking of honest friends. Well, your investments were sound, but there are men of other temperaments they mightn't satisfy. I don't think they would have satisfied Rupert Wyndham."
"Then what did he expect to get in the swamps?"
"I don't know," said Wyndham, with a curious smile. "Perhaps strange experiences; perhaps knowledge and power. I imagine he knew he must buy them and was willing to pay."
"Power over tattooed bushmen!" Marston exclaimed. "What could they teach him?"
"Things we have begun to experiment with and their Ju-Ju men knew long since. The white man who knows the meaning of their tattoo marks has gone some distance; they're not all tribal signs. However, I don't know what Rupert Wyndham learned and it looks as if I shall not find out. Our object's very matter of fact; to earn as much money as possible."
"That is so. I mean to stick to it," said Marston firmly.
Wyndham laughed. "I expect you mean to see I take your line! Well, it's a good line. But we're getting near the bar. Suppose you fetch the chart?"
CHAPTER V
THE TORNADO
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
