Mr. Swift managed to walk slowly to the ladder leading to the conning tower, and thence to the deck. The others followed him. As all emerged from the submarine they uttered a cry of astonishment.
There, not one hundred yards away, was a great warship, flying a flag which, in a moment, Tom recognized as that of Brazil. The cruiser was lying off a small island, and all about were small boats, filled with natives, who seemed to be bringing supplies from land to the ship. At the unexpected sight of the submarine, bobbing up from the bottom of the ocean, the natives uttered cries of fright. The attention of those on the warship was attracted, and the bridge and rails were lined with curious officers and men.
"It's a good thing we didn't come up under that ship," observed Tom. "They would have thought we were trying to torpedo her. Do you feel better, dad?" he asked, his wonder over the sight of the big vessel temporarily eclipsed in his anxiety for his parent.
"Oh, yes, much better. I'm all right now. But I wish we hadn't disclosed ourselves to these people. They may demand to know where we are going, and Brazil is too near Uruguay to make it safe to tell our errand. They may guess it, however, from having read of the wreck, and our departure."
"Oh, I guess it will be all right," replied Captain Weston. "We can tell them we are on a pleasure trip. That's true enough. It would give us great pleasure to find that gold."
"There's a boat, with some officers in it, to judge by the amount of gold lace on them, putting off from the ship," remarked Mr. Sharp.
"Ha! Yes! Evidently they intend to pay us a formal visit," observed Mr. Damon. "Bless my gaiters, though. I'm not dressed to receive company. I think I'll put on my dress suit."
"It's too late," advised Tom. "They'll be here in a minute."
Urged on by the lusty arms of the Brazilian sailors, the boat, containing several officers, neared the floating submarine rapidly.
"Ahoy there!" called an officer in the bow, his accent betraying his unfamiliarity with the English language. "What craft are you?"
