The delight with which this announcement was received by us two boys may be imagined, for though we had hoped for such a decision we had not dared to expect it. I, for my part, had feared that the matter of my interrupted education alone would form an insurmountable barrier; and indeed it was that subject which had proved the chief obstacle, as Uncle Tom presently informed me. All the other objections were minor ones and we discreetly refrained from asking for their recapitulation lest, in going over them again, something not thought of before should crop up to interfere. We were quite content to accept the decision without knowing how it had been arrived at.

As to my interrupted schooling, though, that was a serious matter, as Uncle Tom, in spite of his original ideas about education, clearly understood.

"The main question with me, you see, Frank," said he, "was whether you would benefit or otherwise by missing so much schooling, and though I believe pretty strongly in the value of learning by practice and experience, I should have felt obliged to decide against this expedition if the professor had not come to the rescue. It is to him you owe our decision to let you boys go."

I looked gratefully at Herr Bergen, who serenely waved the stem of his pipe in our direction, though whether to intimate that the obligation was nothing to speak of, or as a sign to Uncle Tom to go on, I could not decide.

"I find," continued the latter, "that the winter is Dick's school-time; and the professor has offered to take you in, Frank, and let you share in Dick's work, undertaking to bring you on in your mathematics in particular—which is your weak spot, you know. In the spring, when the snow clears off, you are to start for the Dos Hermanos and make a thorough search for this old copper mine; and as you will be doing it on my account, I shall bear all expenses. There, that is all, except—well, it is not necessary to mention that—but I was going to say that I rely on you, old fellow, to make the most of your opportunity and in your own person to prove the correctness of my theory that a boy may sometimes learn more out of school than in it."

"I believe you may count on me, Uncle Tom," said I. "I'll do my level best. And I'm tremendously obliged to you, Herr Bergen——"

"Not at all," interrupted the professor, "not at all. The fact is, I am very glad to have a companion for Dick; and as to the schooling, the obligation is not all on one side by any means, for to me it is one of the greatest pleasures possible to teach a boy who really desires to learn. I anticipate a most pleasant winter."

Thus was this odd arrangement made by which I, who by right should have been attending a public school in St. Louis, became the private pupil of an eminent German professor, pursuing my studies in a little log cabin tucked away in a snow-encumbered valley of the Rocky Mountains—about as queer a piece of topsyturviness, to my notion, as ever happened to a boy, and one very unlikely to happen to any other boy, unless he chanced to be endowed with an Uncle Tom cut out on the same pattern as mine.

"There's one thing, Frank," said my guardian, as we made our way down to camp later in the day, "there's one thing I didn't mention in Dick's presence, and that is that the professor laid great stress on the pleasure and advantage it would be to Dick to have a companion of his own age for once, and it was that which turned the balance with me—after the educational question had been got out of the way. For I owe Dick a good turn if I can do him one without hurting anybody else; I told him I wouldn't forget his service in coming down through the storm yesterday, and I haven't forgotten. I'm uncommonly glad to think that in consenting to your taking part in this expedition—which I believe will be a great thing for you, mentally as well as bodily—we shall be doing a service to Dick and to the old professor at the same time."

"Well, Uncle Tom," said I, "you may be sure I am glad enough to stay, and I hope it will not only prove a good thing for Dick and me, but for you as well."
