Professor Chadwick did not fulfill the object of his cruise in finding a new form of biologic life; but he often says that he established something far more precious,—namely, the safety of his long-lost brother-in-law, Tom Jesson’s father.
One morning, not long after the household at High Towers had settled down to its ordinary routine, a telegram came for Jack. It contained astonishing things, things which were—though he didn’t guess it at the time,—to open up an entirely new field of invention for him and his chums, Tom Jesson and Ned Bangs.
The message stated,—but positively, we must keep all that for another telling. In our next volume we will relate further astonishing and stirring occurrences in the lives of our ingenious, progressive young friends. The title of the forthcoming book will be The Boy Inventors and the Vanishing Gun,—a tale which promises to be of extraordinary interest to every American boy, brimful and running over, as it will be, with experiment and achievement along new and significant lines.
