“Wha’ ‘am dat?” he muttered, but said no more.

The instant the object touched the bed of the sea, there was a fearful, blinding flash, an awful boom and shock.

The Dolphin was picked up as if it was a bubble, and hurled through the waters most violently.

It seemed as if it would never cease whirling, when there was a crash and a shock. Then Pomp found himself standing on his head in a corner of the cabin, and Hartley was jammed into another corner.

It was some moments before either recovered breath enough to speak.

Then suddenly the electric lights were paled by the light of day. Both glanced through the windows and saw that they were on the surface of the sea.

The Aurelian was seen some distance away.

“Jemina!” exclaimed Hartley as he gained his feet, “what on earth happened to us?”

“Golly, dat am jes’ wha’ I was finkin’!” cried Pomp.
