"Yes; they were the nearest things to fossils obtainable," I replied, marvelling at my own mendacity.

The professor looked into the hole. I also looked. I could see nothing in it. "He's digging for fossils," thought I to myself.

"Perhaps," said the professor cautiously, "you might wish to aid me in a little research—that is to say, if you have an inclination for fossils." The double-entendre was not lost upon me.

"I have read all your books so eagerly," said I, "that to join you, to be of service to you in any research, however difficult and trying, would be an honour and a privilege that I never dared to hope for."

"That," thought I to myself, "will do its own work."

But the professor was still suspicious. How could he help it, when he remembered Jack's escapades, in which my name was always blended! Doubtless he was satisfied that my influence on Jack was evil. The contrary was the case, too.

"Fossils," he said, worrying the edges of the excavation with his spade, "fossils are not things to be lightly considered."

"No, indeed!" I protested.

"Fossils are the most interesting as well as puzzling things in the world," said he.

"They are!" I cried enthusiastically.
