"It's pretty low," he said, leaning back and surveying his work, "but it may move us along a little."
"How do we know we are going in the right direction?" asked Jack.
"We don't; but we might as well be moving as to stay here. We'll let her have her head and keep her steady as she goes."
Slowly the little craft, before the freshening wind began to make headway.
"This does beat lying still," said Jack. "I don't believe I would have thought of rigging up such a sail as that."
"I guess you would if I hadn't," replied Frank. "Now you try and take a little snooze, while I keep a lookout for a vessel of some kind."
"All right; only, you wake me up in a couple of hours and I'll stand watch."
Frank agreed to this, and Jack rolled over in the bottom of the boat, where, in spite of his wet clothing and the chilling wind, he was soon fast asleep. He was completely exhausted, and any kind of a bed would have felt good to him right then.
Frank, holding the rudder of the boat, sat silent, with his eyes scanning the distant horizon for the sign of a ship. But his watch was vain. Not even the smoke of a patrolling vessel did he see in the distance. His two hours of watch up, he shook Jack vigorously.
The latter was up in an instant, and soon Frank was occupying his place in the bottom of the boat.
