“We did, indeed,” was Jack’s reply.
Readers of “The Boy Inventors’ Wireless Triumph,” the first volume of this series, will agree with him. This story told of the finding of Tom’s father, an explorer long lost in the mysterious land of Yucatan, and also related the odd quest of Prof. Chadwick, including the astonishing adventures of the two young inventors in a wonderful craft of their own designing.
After returning from this exciting trip they encountered, and aided materially, the inventor of a vanishing gun, designed to fight airships. Unscrupulous men tried to steal the plans of the gun, and finally succeeded, but through the boys’ pluck and cleverness their purposes were ultimately foiled. These experiences form a part of the story entitled, “The Boy Inventors and the Vanishing Gun.”
We now find them on the threshold of even stranger adventures than have already befallen them and, having made this necessary digression, let us follow our enterprising lads once more within the hull of the White Shark, the diving craft that so far had not dived.

The colored man agreed to be with them in half an hour, and, much relieved, the boys sauntered out of the shed with Mr. Dancer to await the arrival of the auto.
They were standing in the road outside the gates of the carefully secluded workshop, when a man on a high-powered motorcycle suddenly appeared from the direction of the grade down which the runaway car had dashed.
Mr. Dancer uttered an exclamation as he saw him.
“It’s Adam Duke!” he exclaimed, in a rather perturbed tone.
The words had hardly left his lips before the motorcycle chugged up to where the little group was standing, and the rider swung himself from his seat.
