“Ah, now there—that’s sensible. You may stay, youngster. Pull again now.”

We were all silent for a time, steadily plying our way. At last I ventured to break water once more.

“I am glad, dear uncle, you have revealed to me at last the nature and end of your great experiment. It is the effectual draining of swamps; an attempt, dear uncle, in which, if you do but succeed (as I know you will), you will earn the glory denied to a Roman emperor. He tried to drain the Pontine marsh, but failed.”

“The world has shot ahead the length of its own diameter since then,” quoth my uncle, proudly. “If that Roman emperor were here, I’d show him what can be done in the present enlightened age.”

Seeing my good uncle so far mollified now as to be quite self-complacent, I ventured another remark.

“This is a rather severe, hot pull, dear uncle.”

“Glory is not to be gained, youngster, without pulling hard for it—against the stream, too, as we do now. The natural tendency of man, in the mass, is to go down with the universal current into oblivion.”

“But why pull so far, dear uncle, upon the present occasion? Why pull ten miles for it? You do but propose, as I understand it, to put to the actual test this admirable invention of yours. And could it not be tested almost anywhere?”

“Simple boy,” quoth my uncle, “would you have some malignant spy steal from me the fruits of ten long years of high-hearted, persevering endeavor? Solitary in my scheme, I go to a solitary place to test it. If I fail—for all things are possible—no one out of the family will know it. If I succeed, secure in the secrecy of my invention, I can boldly demand any price for its publication.”

“Pardon me, dear uncle; you are wiser than I.”
