Save one, an elderly officer, apparently of high rank, who came forward and raised his hand to the salute.

"Captain Rennell," he said, "we are at war with your nation, but we are also, I hope, gentlemen." He turned to Von Kettler. "Is it seemly," he asked, "that an officer of the American army should be brought here in chains and cords?"

"Excellency, it is His Majesty's command," responded Von Kettler, with a servile smirk that hardly concealed his elation. "Moreover, the American is to witness the forthcoming destruction of the Yankee fleet."

The elderly officer reddened, turned away without replying. Dick looked about him.


here was less machinery in this room. The iron pillar that he had seen came through the floor and terminated some five feet above it in another of the opaque glass domes, filled with iridescent fire. About it was a complicated arrangement of dials and gauges.

In the centre of the room was a sort of camera obscura. A large hood projected above a flat table, and an officer was half-concealed beneath it, apparently studying the table busily.

"Come, American, you shall see your navy on its way to destruction," said Von Kettler, beckoning Dick within the hood.

The officer stepped from the table, whose top was a sheet of silvered glass, leaving Von Kettler and Dick in front of it. Dick looked. At first he could see nothing but the vast stretch of sea; then he began to make out tiny dots at the table's end, terminating in minute blurs that were evidently smoke from the funnels.
