"Will it work, matey?"

"It ought to—providing there is anything for it to work with. When you talk by wireless, Dick, you know there has got to be a second instrument within reach of your Hertzian waves. Lucky we were able to pick up that wireless instrument in Buenos Ayres. Lucky, too, that Ensign Glennie knows how to use the key and to talk Spanish."

Just behind a bold headland to the north of Cape Virgins and within the mouth of the River Gallego, the submarine Grampus was anchored. The shore of the little bay lay steep to, the submarine being moored within a jump of the wooded bank.

Wires issued from the conning-tower hatch of the craft, crossed the stretch of water, and climbed a high tree that had been stripped of its branches. From the top of the tree hung the aërials. Below deck, in the periscope room, was the instrument, with John Henry Glennie, Ensign, U. S. N., waiting at the key.

Motor Matt and Dick Ferral were on deck.

"Are you sure, matey," went on Dick, "that that was the Jap steamer our lookout raised from the headland?"

"We can't be sure of anything where those Japs are concerned. The steamer was of about the same size, although differently painted. But, then, paint is cheap, and it sometimes makes a big difference in a boat's appearance. The suspicious circumstance is that, while she was passing the mouth of the Gallegos, she pulled down the cross of St. George and ran up the Chilian flag."

"And she had two wireless masts!" exclaimed Dick. "These Sons of the Rising Sun are wily chaps, but, seeing that we have come from Para, all down the eastern coast of South America without any trouble, I was beginning to think the Japs had given up, and that they were going to let us finish our long cruise without paying us any more attention."

"Remember what Mr. Brigham, the American consul at Para, told us, Dick—that these fanatical young Japs never turn back once they have set their hands to a piece of work. Our business is to get the Grampus around the Horn and into the hands of the commandant of the navy yard at Mare Island, and collect a hundred thousand dollars for Captain Nemo, Jr. The Sons of the Rising Sun came near winning while we were on the way from Port of Spain to Para, and the mere fact that we got the best of them isn't going to cause them to throw up their hands and haul off."[A]
