CHAPTER XI.
A MYSTERY.

The two boys kept well apart from the crew, and watched closely for any signs of threatened trouble, but, although the men looked sullen and ugly enough for any kind of act, they seemed much subdued and went about their tasks quietly saying little, even to each other.

"I guess we are giving ourselves a lot of worry without cause," Walter remarked, softly. "Those fellows seem quiet enough now. It was the liquor that made them act as they did last night, but they have drank it all up now and I do not believe we will have any more trouble with them."

"I wish I could agree with you," his chum said, gravely, "but I can't. I believe in the old Latin proverb—'in vino veritas'—there is truth in wine. I've always noticed that when a man gets intoxicated, he reveals just the kind of man he really is. If he is naturally quarrelsome when sober he is sure to want to fight when drinking. If he is good-hearted and kind when sober, he is generally good-humored when drunk. Liquor seems to destroy a man's caution and make him reveal his real character. Now these fellows showed plainly their feelings towards us last night when they were drinking. To-day they are sober and more cautious, but I believe they feel just the same towards us. It only needs some real or fancied wrong to bring their hatred to the surface again. I believe if we had a clash with one of them now we would have a first-class mutiny on our hands; but, I guess, we had not better do any more whimpering. They will suspect that we are discussing them and it will not improve matters any."

For awhile the sponges came up from below every half hour, but towards noon a full hour went by without the basket making its appearance. The lads, at last, became somewhat alarmed at the delay.

"Do you suppose they are in any trouble down below?" Charley enquired of Manuel.

The Greek shook his head. "They would have signaled if anything had been wrong. There, they are signaling now."

There came several jerks on the life-lines and the Greeks in charge of them pulled the divers up and into the boat. The men had been below for only an hour and the boys were puzzled to account for their coming up before their time had expired. When their head-pieces were removed the lads could see that the divers were greatly excited. They spoke rapidly to those around them, and a hum of excited conversation arose from the before listless crew.
