"You had it brought in here to save room, I suppose," said the captain.

"I noticed that you were all cluttered up outside."

"Why, it wasn't that exactly," replied Tyke, slightly embarra.s.sed.

"You see, Allen an' I were rummaging around in the top loft the other day, an' among other things our eyes fell on this box. That started me off yarning about the tight places Manuel an' I had been in together, an' how he'd hinted that some day he'd be rich. Then I told Allen of how Manuel said, when he left his box with me, that there was something in it worth more'n diamonds an' then----

"Yes, I can guess the rest," said Captain Hamilton, with a quiet smile.

"And then you both got a hankering to see what was in the box."

"Allen did," admitted Tyke, "'an' I ain't denying that my fingers itched a little too. But I put it off until we had got moved into our new place. Now, didn't I, Allen?" he demanded virtuously.

Drew a.s.sented smilingly.

"Why didn't you wait then?" gibed the captain.

"We would have," affirmed Grimshaw eagerly, conscious that here at last he was on firm ground, "but that black rascal, Sam, the porter, dropped the box on his way downstairs an' it split wide open, as you see. If I was superst.i.tious----" here he glared challengingly at both of his listeners, who by an effort kept their faces grave, "I'd sure think it was meant that we should look into it right away. What do you say, Cap'n Rufe?"

"I agree with you," replied the captain. "The man is dead, and the box is yours by right of storage if nothing else. This Manuel didn't have wife or children that you know of, did he?"

"Nary one," responded Grimshaw. "When he'd been drinking too much he used to cry sometimes an' say that he hadn't a relative in the world to care whether he lived or died."

"That being the case, heave ahead," advised the captain. "You don't owe anything to the living or the dead to keep you from finding out all you want to know."

Reinforced by this opinion, the old man again lifted the coat from the top of the box.

What lay beneath was a curious medley of articles such as might have been gathered at various times by a sailor who was familiar with all the ports of the world. Mingled in with old trousers and boots and caps, were curiously tinted sh.e.l.ls, clasp knives with broken blades, grotesque images of heathen G.o.ds, a tarantula and a centipede preserved in a small jar of alcohol, miraculously saved from breakage.

But what especially attracted their attention in the midst of this miscellaneous riffraff was a small cedar box, about eight inches long by six inches wide and deep. It was heavily carved, and was secured by a lock of unusual size and strength.

"Wonder if this is the thing that was worth more'n diamonds," grunted Tyke, with a carelessness that was too elaborate not to be a.s.sumed.

"It must be that, if anything," replied Captain Hamilton, who had let his cigar go out and was now vigorously chewing the stub.

Drew said nothing, but his cheeks were flushed and his eyes brighter than usual.

Grimshaw fumbled with the lock for a moment, but found it immovable.

"Jest step out, Allen, and get all the keys we have an' we'll see if any of 'em fit," he directed.

Drew did so, and returned in a moment with the entire collection that the shop boasted. Tyke tried them all in turn, but none fitted.

"I guess there's no help for it," he said at last. "I hate to spoil the box, but we'll have to force the lock. Get a chisel, and we'll pry the thing open."

The chisel was brought and did its work promptly. There was a rasping, groaning sound, as if the box were complaining at this rude a.s.sault upon its privacy, then, with a hand that trembled a little, Tyke lifted the cover.

All three heads were close together as the men bent over and peered in.

Their first glimpse brought a sense of disappointment. They had half expected to catch the sheen of gold or the glitter of jewels. Instead they saw only a piece of oilskin that was carefully wrapped about what proved to be some sheets of paper almost as stiff as parchment.

"Huh," grunted Tyke. "Pesky lot of trouble with mighty little result.

I told you I thought Manuel was a bit touched in the brain, an' I guess I was right."

"Wait a minute," said Captain Hamilton. "Don't go off at half-c.o.c.k.

Let's see what's in that oil-skin."

Tyke opened the packet. The others drew up their chairs, one on either side, as he unfolded the oilskin carefully on his desk.

There were two sheets of paper inside, so old and mildewed that they had to be handled carefully to prevent their falling to pieces.

One of the papers seemed to be an official statement written in Spanish. The other consisted of rude tracings, moving apparently at random, with here and there a word that was almost illegible.

The three men looked at this blankly. Drew was the first to speak.

"It's a map!" he exclaimed eagerly.

CHAPTER VII

A MYSTERIOUS DOc.u.mENT

The two captains scanned the doc.u.ment closely.

"It certainly is a map," p.r.o.nounced Captain Hamilton decisively.

"That's what it 'pears to be," admitted Tyke.

"And it's the map of an island," went on Hamilton. "See," he pointed out, "these wavy lines are meant to represent water and these firmer lines stand for the land."

The others followed the movement of his finger and agreed with him.

"Well, after all, what of it?" asked Tyke, leaning back in his chair with affected indifference.

"There's this of it," said his visitor throwing his extinguished cigar into the waste-basket and drawing his chair still closer. "I feel that we have a mystery on our hands, and we should examine it fore and aft to find what there is in it."

"I s'pose the next thing you'll be saying is that's it's a guide to hidden treasure or something like that," jeered Tyke feebly, to conceal his own growing excitement.

"Stranger things than that have happened," replied the captain sententiously.

"Have it your own way," a.s.sented Tyke, rising and going to the door.

"Winters," he called, "jest remember that I'm not in to anybody for the rest of the afternoon."

"Yes, sir," replied Winters dutifully.

Having locked the door as an additional guard against intrusion, Tyke rejoined the two at the desk.

"Fire away," he directed. "What's the first move?"
