INTRODUCTION
My Dear Boys:
Sometimes, as you doubtless know, the simplest actions result in the most remarkable complications. When Jerry Hopkins picked up a lump of common-looking clay on some swamp land that his mother owned he had no idea what a strange series of events was to transpire from his simple act. Before he realized it he and his chums were involved in a strange secret, and they had set off on a trip that had, as its ultimate object, the saving of the life of Professor Snodgrass.
In this, the sixteenth volume of the “Motor Boys Series,” I have set down what followed when Jerry learned the value of that lump of clay. How he and his chums started off after the professor, who had strangely disappeared; how they found him, almost lifeless; and how they raced to bring the celebrated doctor to him—all this you will find related in this book.
You have shown that you liked the other books I have written concerning the “Motor Boys,” and I venture to hope that this one will appeal to you.
That there was really a two-tailed lizard was left for Bob to demonstrate in an unexpected manner. That is all I will say, now, regarding that strange creature. You may turn the following pages and learn the rest for yourselves.
Your sincere friend,
Clarence Young.
