When Marston woke in the morning his headache and languidness had gone. It looked as if the powder the mulatto had left had cured him, and although he did not find the laudanum and packet of drugs, he resolved he would not bother about their loss. In a day or two, small lots of rather valuable cargo began to arrive and one afternoon Marston and Wyndham lounged under the awning and watched the Krooboys transfer goods from a big canoe to the yacht. Four or five negroes from up river put the fiber packages in the hoisting slings. The men worked slackly, for although the sun was hidden the heat was extreme. A yellow haze covered the sky, but the oily surface of the lagoon shimmered with subdued light. On the other side, the reflection of the mangroves floated motionless, without a leaf quivering. Dark shadow lurked in the caves under the high roots, and here and there the massed foliage was touched by dirty white. Marston thought the trees looked as if they were blighted by some foul disease. He hated the mangroves and the smell of mud that hung about the vessel. "The tides are beginning to get higher," he said. "It will be a relief to leave this dismal spot and go to sea." "Calling here has paid us," Wyndham rejoined. "We are getting stuff for which dyers and chemists give high prices; stuff I wanted but hardly expected to obtain. In fact, I'll own your mysterious visitor has earned his dash. No doubt he'll turn up again and ask for it." "D'you reckon he had much to do with our getting the goods?" Wyndham shrugged. "I understand he promised you the articles you talked about, and they have arrived. If he comes again, I'd like to see him. Perhaps he could be persuaded to send us something else." "He asked for you," said Marston, and wondered whether his remark was rash when he saw Wyndham was pondering. Although Bob felt he was perhaps illogical, he did not want Harry to persuade the fellow. "I think you said his eyes were blue," Wyndham resumed presently. "Well, one does meet a mulatto with blue eyes now and then, and it's perhaps not important that the bottom of his feet was white----" Wyndham stopped, for a splash of paddles broke the silence, and when a canoe stole out of the shadow across the lagoon Marston said. "We may learn something about him now. Here's your agent, Don Felix."
