"My row with him ain't the worst of the matter," the old sailor said gravely. "I called on the crew to help me iron him and they all pretended they didn't understand my sign, but they knew what I wanted all right. I had to handle him alone an' we had quite a struggle before I got the best of him." He rolled up his sleeve and showed an ugly-looking cut on his arm. "He came near getting me with his knife an' I had to give him a couple of taps with a belaying pin. That cut don't amount to anything, but what worries me is that the crew stood around an' watched him try to kill me without interfering—it's a mighty bad sign."

"That does look bad," Charley agreed, anxiously. "I guess we had better keep him a close prisoner and not let any of the crew go near him, he might try to stir them up and make things hot for us."

"But that means that someone will have to guard him an' carry his meals to him. It wouldn't do to have one of the Greeks do it, I reckon."

"No," Charley agreed, thoughtfully, "but I believe I've got the very man for the job—that handsome fellow the others seem to hate so. Manuel tried to kill him and he is not likely to be easy with him."

The mysterious sailor was at once sent for by Ben. As soon as he came the captain loaded a tray with food and a bottle of water and signed for him to carry it and follow him. Charley and Walter accompanied the two.

As they passed along the deck on their way to the hold, they met angry glances and frowns from the crew.

The mysterious sailor was very intelligent and they soon made him understand that he was to guard the prisoner. He grinned with enjoyment and, seating himself a little way from the Greek, took out his long keen sheath knife and laid it handy beside him.

The prisoner's face grew black with rage at sight of his guard, but he maintained a sulky silence.

"I guess he's safe enough now," the captain said as they returned to their cabin. "I believe that fellow will guard him faithfully. They seem to hate each other like poison—I wish I knew the reason for it."

"It would not seem so strange if the hatred was confined to him and Manuel, but all the others seem to share in the feeling," Charley remarked. "It seems very queer to me."
