After a moment, Mr. Cledd spoke up frankly. "I'll take back what I've just said. I see it too. It's only a junk, but I suppose we'd better call the captain."

"Only a junk!" Blodgett repeated sharply. "When last we saw 'em, a junk was all they had."

"What's that?" Mr. Cledd demanded.

"Ay, ay, sir, they was sailing away in a junk, sir."

Mr. Cledd stepped to the companionway. "Captain Hamlin," he called.

The junk was running free when we first sighted her, but just as she was passing astern of us, she began to come slowly about. I could see a great number of men swaying in unison against the helm that controlled the gigantic rudder. Others were bracing the curious old sails.

"I wish she were near enough for us to watch them handle the sails on the after masts," I said.

She had a pair of mizzen-masts, one on the larboard side, one on the starboard, and I was puzzled to know how they were used.

"She'll pass close aboard on this next tack," Mr. Cledd replied. "I think we'll be able to see." He had paused to watch her manoeuvres.

"Here's the doctor," Blodgett murmured.
