Both the elder lads gazed sharply.

"That's not the direction in which land would lie," mused Tubby.

"The light's pretty high up, too, isn't it?" suggested Merritt. "It might be a lighthouse. We may have been blown farther than we thought."

Tubby offered no opinion for a few seconds, but his ordinarily round and smiling face grew grave. A sudden apprehension had flashed into his mind.

"Tell me, Merritt," he said, "can you see any other lights?"

"No," replied Merritt, after peering with half closed eyes at the white light.

"I can," suddenly shouted young Hiram.

"You can?"

"Yes; some distance below the white light I can see a green one to the right and a red one on the left."

"Shades of Father Neptune!" groaned Tubby. "It's just as I thought, Merritt—that light yonder is a steamer's mast lantern, and the fact that Hiram can see both her port and starboard lamps beneath shows that she's coming right for us."
