"What are you going to do about it?" Mr. Oliver asked. "Wait and keep my eyes open. If it appears advisable I may communicate with the Canadian authorities later on, though, of course, we must contrive to get our hands on the fellows in American waters. I've an idea it can be done." Mr. Oliver said nothing further, and by and by, when a thin haze rolled down from the hillside and night closed in, they strolled toward the rancherie, where they were given a strip of floor space not far from the entrance. The boys came in a little later and lay down apart from them and nearer the door, but Frank did not go to sleep. The rancherie was hot and the dull roar of the combers on the reef came throbbing in and made him restless. He lay still for what seemed a considerable time, and at last there was a low sound which might have been made by somebody rising stealthily, after which a dim black object flitted out of the door. Then Harry, who lay close to him, touched his arm. "Are you asleep?" he asked very softly. "No," answered Frank. "Where's that fellow going?" "Get out as quietly as you can," was Harry's reply. Frank had kept his shirt and trousers on, and after feeling for his boots he arose cautiously, holding them in his hand. In another moment or two he had slipped out into the cool night air and was crossing the shingle in his stockinged feet. Once or twice a stone rattled, but he supposed the sound was lost in the clamor of the reef, for nobody seemed to hear it. When they had left the rancherie some distance behind they sat down. "Now," said Harry, "I'll tell you my idea. They're expecting the schooner and don't want her to run in while we're about. They've probably had a man on the lookout down by the entrance, and I expect the fellow who went out has been sent by the boss or Tyee to learn if the other one has seen her." "It's curious some of them didn't hear us," Frank observed thoughtfully. "I'm not sure that they didn't," Harry admitted. "Anyway, they couldn't stop us without some excuse, and, if I'm right, they certainly wouldn't want to tell us why they wished us to stay in. Of course," he added, "it might make them suspicious, but I don't know any reason why we should point that out to Barclay. The great thing is to keep out of sight in case they follow us."
