The Radio Boys Under the Sea: or, The Hunt for Sunken Treasure. Duffield J. W.

in 1812 with $32,000,000 in gold doubloons on board. You’ve read perhaps of the American ship Phantom that was wrecked in 1862 with $10,000,000 in California gold. The George Sand sank in the China Sea in 1863 carrying down $13,000,000 in bullion. And those are only a few of the hundreds of ships that have carried down hundreds of thousands or millions. There’s probably enough gold under the waves to make a solid golden pathway a good many feet wide over the whole of the ocean bed.”

      “Well, here’s hoping that there’ll be less of it under water when we get through,” laughed Tom.

      “Let’s hope so,” smiled Benton, “but now let’s shift for a little while to another metal and get right down to brass tacks.”

      CHAPTER VIII

      COUNTING THE COST

      “The first thing to be done,” continued Benton, as they all gathered about the table, “is to figure on the cost of the expedition. In this, as in everything else, we need the ‘sinews of war.’ We’ve got to lay in supplies, purchase a diving suit, charter a sailing vessel after we reach San Domingo and lots of other things. It can’t be done under five thousand dollars and we’d better figure on ten. How about it?”

      “That’s all right,” answered Phil promptly. “We’ve talked it over among ourselves and estimated that it would be somewhere between those two amounts. A year ago it might have stumped us a bit, but the reward we got from the bank for the capture of Muggs Murray and the generous way in which Uncle Sam treated us after we had helped to run down the counterfeiters has put us on Easy Street.”

      “Good,” said Benton. “I have a little wad of my own stowed away, and we’ll go in on an even basis. There are five of us – that is, if your friend Elwood comes in with us – and that will make from one to two thousand each that we will have to put up. And of course it is understood that we share alike in all the profits of the expedition.”

      “Seems to me that you ought to have a larger share than the rest of us,” objected Phil. “You’re the one that got the papers, without which there wouldn’t be any trip at all.”

      “Not a bit of it,” protested Benton. “The papers wouldn’t do me any good unless I had fellows like you to help me realize on them. No, it’s got to be ‘hoss and hoss,’ share and share alike. That is,” he added, with his whimsical smile, “if there’s anything to be shared. We’re counting our chickens before they are hatched.”

      “I suppose the first leg of our journey will be from here to some of the West India Islands,” said Dick.

      “Yes,” answered Benton. “I figure that we’d better go from here to New York by rail, and then by one of the regular steamers to San Domingo. When we reach there, it will be up to us to charter a small fast sailing vessel in which we can cruise around in the Caribbean while we’re trying to locate the old pirate’s island. We’ll drop down to the neighborhood of latitude 14, longitude 81, keeping our eyes open for any island whose skyline looks like the teeth of a saw.”

      “How about navigating the sloop?” asked Phil.

      “Leave that to me,” responded Benton. “I thought one time before I joined the marines of going into the merchant service and studied for the position of mate. I got my papers too and can handle a ship with the best of them. But the marine service appealed to me more strongly because of the greater chances of adventure, and so I passed the other up. But I haven’t let myself get rusty, and I’ve had a lot of practical experience. I’m as much at home on a boat as I am in the barracks. But how about you young fellows? Know anything about sailing?”

      “Not on the ocean,” replied Phil, “but we’ve done considerable cruising on the Great Lakes, which are the next thing to the sea itself. We know enough about ropes and sails to understand orders and to obey them promptly. If you’ll act as captain, we think we can qualify as crew, especially on as small a boat as we expect to handle.”

      “That’s dandy,” replied Benton, “and when we get down to San Domingo we’ll do a lot of cruising just off shore so that you can get thoroughly familiar with your work before cutting loose for the big adventure. That removes a lot of worry from my mind, for I’d hate like thunder to have to ship a crew from the kind of material you find in a West Indian port. They’re smart enough sailors, but as a rule a bad lot to have on any trip, let alone an expedition that’s looking for treasure.

      “Now as to supplies. We’ve got to take along guns, revolvers and plenty of ammunition. Then we’ll need dynamite and blasting powder – ”

      “I don’t see exactly where that comes in,” remarked Tom.

      “For use in getting to the treasure,” explained Benton. “Granted that we locate the ship, it’s altogether unlikely that we’d be able to get through the hatches. They’d in all likelihood be crusted with barnacles or covered with silt and sea growths that would make it impossible for the diver to get into the hold unaided. But he could plant a charge of dynamite, and then after he’d been drawn up the charge could be fired by means of an electric spark from a battery in the boat above. That would tear a big hole in the deck and give the diver a chance to get in.

      “Speaking of the diver,” Benton went on, “brings us to one of the most important things of all, and that is the diving suit. We can’t afford to get any but the best, for the man that goes down in it literally takes his life in his hands. The work though is less dangerous than it used to be because of the improvements that have been made.

      “For instance, in the old-fashioned suits the fresh air was served to the diver from the surface of the water through a tube and the pressure within the suit was increased to equal the pressure outside of it. But the more modern suit that I have in mind eliminates the necessity of the air tube. The diver carries his own oxygen with him in a tank that is fitted into a steel shell that is a part of the suit. Beside the oxygen tank is another tank containing caustic soda which absorbs the carbon dioxide given out by the expelled breath of the diver. A valve operates to deliver a certain amount every hour of oxygen properly mixed with nitrogen.
