“Clear out!” snorted Henninger. “She’d overtake us in an hour, with her engines. She’s got no guns, that I can see. Ten to one it’s our friends from Zanzibar.” He continued to gaze through the binoculars.

“By Jove, she’s getting ready to lower a boat!” he exclaimed, after a minute or two. “Sullivan, please bring up those rifles and open a case of ammunition. Bring up a case of revolver cartridges, too. Elliott, tell the skipper to get those anchors up, and bring her around.”

The strange steamer was indeed lowering a boat which was full of men, and as it left her side half a dozen dull flashes, as of blued steel, glimmered in the sun. Sullivan darted below and came up with his arms full of Mausers, which he stacked against the after-rail. The Arabs were set to work at the capstan, and the forward anchor was broken out, but the kedge attached to the reef was allowed to remain for the present. Without it, the dhow would have drifted upon the island, for the bright morning was turning cloudy, with a rising breeze from the southeast.

There was hurry and excitement upon her decks as she lay head to the freshening weather, straining at her single cable. The Arabs were clustered at the bow, talking violently among themselves, and gesticulating at the mysterious steamer. Henninger watched them with an air of suspicion, and proceeded to load his revolver, and put a handful of cartridges in his pocket. Every one followed his example, and Margaret produced her own pistol, which she had not shown since the night of her coming aboard.

“Oh, is there going to be a fight?” she breathed in a tremulous voice, which her bright eyes attributed to excitement rather than to fright.

“No. At least, I hope not,” said Henninger. “If there should be, you’ll go below and stay there, Miss Laurie. You understand?”

“Look,” she cried, in answer. “They’re waving a white flag.”

The boat, which had almost reached the barrier reef, had stopped, and a strip of white cloth was being flourished from her stern.

“That settles it,” Elliott remarked. “It must be Carlton and Sevier’s gang. They want to talk to us.”

“We’ll talk to them, but they mustn’t come alongside us,” responded Henninger. “We’ll go ashore to meet them. Elliott, will you come with me? The rest of you had better stand by with the rifles while the peace conference is going on.”
