It was now after Barney and Von Bulow.

But Frank’s fracas with it had given them a chance to get a good lead.

They were now quite near the Dart, and were enabled to reach it in time.

On to the deck and into the vestibule they dashed.

The next moment the submarine boat received a terrific shock.

The sea serpent struck it full force, and for a moment it seemed as if the fate of the Dart was sealed.

But, as good luck had it, the steel work of the boat was harder than the serpent’s head.

It resisted the shock. But Pomp and Captain Bell were thrown across the cabin.

They had seen the serpent coming in pursuit of Von Bulow and Barney, and it had given them a thrill.

“Golly!” screamed Pomp. “De debbil am after dem. Shuah nuff dat big snake will swallow us all up!”
