So it will be seen that Ned was in no position to give further attention to the wreck, or the gold it might or might not contain until he had done everything in his power to secure the papers, if any had been found, before they could be destroyed or delivered.
And now the question was this:
"How can I get to the Shark and have a look through the plunder taken from the wreck?"
The decision was that he could not accomplish such a mission. It would be impossible for him to board the Shark, or make a search even if he should succeed in getting into the rival submarine.
What next? The men on board the Shark would undoubtedly go ash.o.r.e if the boat remained long in the bay. Why not land and watch about the island for the arrival of the foreign conspirators?
The island was not a large one, and there were few inhabitants, so a meeting such as Ned believed was set for the place could not fail to attract some attention. Well, the first thing to do, he reasoned, was to discover if the Shark was sending her men on sh.o.r.e.
"Jimmie," he said, as he returned to the conning tower, "how would you like to go hunting in the bottom of the sea?"
"Fine!" shouted the lad.
"Bring in a catfish with a bunch of kittens," Frank laughed. "I"m afraid we have mice in the provision room."
"I"ll find a dogfish with a couple of puppies," replied Jimmie, "so we can have plenty of bark to build fires with."
"A bad joke," Frank replied. "If you"d quit studying up slang and read the best authors you wouldn"t inflict such pain-giving jolts."
"Who"s going with the kid?" asked Jack, sticking his nose up through the open hatchway.
"I am," replied Frank, calmly. "It is not safe to trust him on the island alone."
"What do you want me to hunt?" asked Jimmie, turning his back on the two boys.
"Information."
"I can get that in a book," said Jimmie, with a wink at Frank.
"Get into your promenade suit," Ned continued, "and I"ll let you out on the bottom. Then I"ll warp the Sea Lion around that point of land, so you can see where the Shark lies and what is going on, if anything."
"Carry me around the point of land before you drop me," suggested the little fellow.
"No," Ned answered. "I want you to search the ocean floor on the way around the point. The rascals may have laid mines there, or the people on board may be making trips to the point, just to see what we are up to. Understand?"
"Oh, yes, I see the point, all right," was the reply. "And you want me to go out in the wet and inspect another point?"
"Cut it out!" cried Jack.
Jimmie ran off, laughing, to put on his deep-sea suit, and in a moment was back asking Ned to set his helmet in place.
"When you get down to the bottom," Ned said, before attaching the heavy headpiece, "keep hold of your lifting line and signal stop or forward, just as you find it easy or difficult to make your way along the level. One jerk for stop and two to go ahead. You won"t forget that. Think of the signals on the surface cars in little Old New York."
"And keep your eyes out for signs of air-hose and lines on the bottom," Frank put in.
"All right," the boy cried, cheerfully.
"You have a long air-hose and a very long line," Ned went on, "so you can go up the bay where the Shark lies quite a distance after we stop the Sea Lion at the point."
The helmet was now put on, the lad pa.s.sed through the water chamber, and directly there came a signal on the line--two quick jerks.
The submarine moved slowly ahead, and Jimmie almost crawled on the bed of the ocean. The water was not very deep, not more than ten fathoms, and the bright sunlight enabled the boy to see quite well.
Fishes, large and small, sea reptiles, hideous in aspect and attractive as to coloring, swam around him, and terrifying forms rose from the bottom and rubbed against his helmet windows. He felt safer on the bottom, for then the creatures could come at him in only one way.
Presently the sand in front of him showed commotion. It stirred and clouded the water. Jimmie stopped and looked, drawing his weapon--the razor-pointed steel bar--to the front as he did so. Then he felt something close about an ankle and draw him down. A serpent"s head showed on a level with his shoulder.
CHAPTER XII
JACK MAKES A DISCOVERY
"Now," Ned said, when the Sea Lion stopped in response to a quick pull from below, "who is going to sh.o.r.e with me?"
"Me for the sh.o.r.e!"
Both boys spoke at once.
"But one must remain on board," declared Ned.
"Then let Frank stay," laughed Jack. "Somehow, I always get into trouble when I am left on guard."
Frank looked disappointed, but said nothing, and Ned and Jack prepared to go ash.o.r.e. When they were ready the submarine was carefully raised so that the conning tower was out of water.
The boys did not know, while they were doing this, that the signal to stop was an involuntary one on the part of the boy who was exploring the ocean floor. They did know, however, that Jimmie had a very long air-and signal-system, and that under ordinary circ.u.mstances it could do no harm to lift the Sea Lion to the surface. The exact effect of this action on the little fellow will be seen in a short time.
When the conning tower was out of water, the point showed still ahead of the submarine, and Ned wondered why Jimmie had ordered a halt there. In one way this was an advantage, as the people at the head of the bay, if any were there, would not be able to see what was going on at the spot where the Sea Lion lay.
As soon as the hatch was opened Ned and Jack brought up a small boat and launched it. It was a narrow boat and seemed almost too small to carry two husky boys, but she was capable of harder service than that.
"Keep a sharp watch for the line," Ned warned, as they left Frank looking sadly over the rim of the tower. "Jimmie would be in a bad box down there if you should forget him."
"All right!" Frank answered, cheerfully. "I"ll take care of the little scamp, but I don"t believe there is water enough in the ocean to drown him!"
The boys, paddling the boat softly, proceeded to the west of the point of land near which the Sea lion had stationed herself. Ahead of them they saw a sloping sh.o.r.e, running white and smooth as to surface for some distance from the water. Then, at the back, rose a line of wooded hills. There were no natives in sight.
"I"d like to know what kind of people live on this island," Jack said as they landed and drew the boat up on the beach. "Whoever they are, they don"t appear to have houses."
They crossed the white rim of beach, keeping their eyes on the boat as they advanced, and came to an elevation in the wild country beyond.
From this elevation a small clearing showed to the east, and in the clearing were a number of buildings, some residences of a poor type and some evidently erected for business purposes.
"There," Ned said, pointing, "if we could get down into the cl.u.s.ter of buildings, with an interpreter, we might find out whether the Shark fellows have landed yet, and whether there are strangers loitering about the island."
