Dave Fearless and the Cave of Mystery Part 12

"Give them their walking papers, Mr. Drake," rang out Broadbeam to the boatswain.

The latter ran up a signal flag. This signified that the _Swallow_ announced herself two-and-one-half miles from sh.o.r.e, and therefore out of the jurisdiction of Minotaur Island, claiming the freedom of neutral waters.

"That'll hold her for a while," gloated Stoodles. "Aha! ye'll have to take back wather now."

The gunboat reminded Dave of some spiteful being cheated out of its prey. She circled, spit steam, and went more slowly back to port.

Captain Broadbeam now ordered the _Swallow_ just without the shoal line of a big sandy island they had neared. Here they came to anchor.

Bob Vilett came up on deck reeking with the steam and grease of the engine room.

"What's the programme, Bob?" asked Dave.

"Captain says we are going to stop here and take on ballast."

"For how long?"

"Till to-morrow, I reckon. I say, Dave, you've got your heart's desire, eh?"

"I am the happiest boy living," answered the young diver. "Something tells me we are going to get and enjoy that treasure after all mishaps and disappointments."

In order to repair the _Swallow_ in the creek, the ballast had been taken out and the contents of the hold generally s.h.i.+fted about.

Now the captain set his men at work to take on new sand ballast from the island and get things in the hold in regular order.

A pulley cable was run ash.o.r.e. Dave and Bob were the first to take an aerial spin along this, dangling from the big iron kettle that ran down the incline.

Dave had told Captain Broadbeam and the others of his agency in the matter of subst.i.tuting the hornets for the opium. The recital had made the captain good-natured, and he had given the boys permission to rove over the sand island at will for the day.

Dave and Bob put in a pleasant hour or two talking, fis.h.i.+ng, and discussing the probable adventures that would greet them when they again visited the Windjammers' Island.

At about five o'clock in the afternoon the work of securing ballast was completed. The captain then announced that there was some work still to do in the hold. They would make their real start with daylight.

Dave and Bob were taking a last swim in the cool of the day. A clear sky and a fine breeze made the exercise delightful. Finally they got daring one another. Dave swam to the little sand islet next to the large one. Bob beat him in a race to the third of the group.

"Come on, if you've got the nerve," hailed Dave, making a quarter-mile dash for a sand mound still beyond them.

Bob started, but turned back. Dave made port and threw himself on the dry sand to rest. He got back his breath and sat up ready to take the home course, when his eye was attracted to something on an island about a furlong beyond the one he was on.

This was the nearest of the wooded islands. Dave had not noticed it much before. What made him notice it now was that, half-hidden in a great growth of bushes and vines, he noticed a small log hut.

In front of this a mast ran up into the air. At the moment that Dave looked he saw a man fumbling at the lines along this mast. It was to raise a blue bunting.

"h.e.l.lo, h.e.l.lo," murmured Dave slowly, staring hard and thinking desperately fast. "Why, that's easy to guess. That man is Schmitt-Schmitt."

Dave could not precisely recognize the man at such a distance, but felt sure that it was Schmitt-Schmitt. He thought this the more positively as he saw that piece of blue bunting run up the mast.

"That was one of the signals I heard Schmitt-Schmitt tell the pilot about," mused Dave. "Red for provisions, blue for sickness or help wanted. Lantern at night, bunting by day. That's it, sure. He is signaling the pilot. That island is Schmitt-Schmitt's place of hiding.

Say, here's something to think about."

Dave did not stay long to think about it. His eyes brightened and he seemed moved by some inspiriting idea as he jumped into the water and was soon back in the company of his chum, Bob Vilett.

Dave was quite silent and meditative till they had reached the big sandy island. Arrived there, he slowly dressed himself.

"Come on, I'm hungry as a bear--don't want to miss a good supper, Dave,"

hailed Bob, starting for the _Swallow_.

"Hold on!" challenged Dave. "I want to tell you something before we go aboard."

"Fire away," directed Bob.

"Can you manage to get off duty about dusk?"

"There's nothing for me to do till we steam up again," replied Bob.

"Why?"

"Can we get one of the small boats for an hour or two, do you think?"

Bob shook his head negatively.

"Heard the captain shut down on the chance of anybody sneaking to town and making more trouble. No, it can't be done, unless the captain gives special orders. Why?" pressed Bob curiously.

"I don't want to tell the captain what I am up to till I accomplish something," explained Dave. "I'll tell you, though, for you've got to help me."

"All right, Dave," piped Bob readily.

"We must rig up some kind of a craft to reach the first wooded island."

"What for?"

"Schmitt-Schmitt is in hiding there."

"Aha, I see!" cried Bob excitedly.

"I propose," said Dave deliberately, "that we visit him, capture him, and bring on board the _Swallow_--as a prisoner--the only man probably who can guide us straight to that stolen treasure."

"Famous!" cried Bob Vilett enthusiastically--"but can we do it?"

"Let's try it, anyhow," answered Dave Fearless.

CHAPTER X

THE WOODED ISLAND

Captain Broadbeam gave pretty strict orders at dusk. A watch was set with directions to allow no one to leave the _Swallow_. All the small boats were chained stoutly.
