"I hope so, too. And it will, if you can locate that old copper mine, and if it should prove to be anywhere near as good as it sounds."

As things turned out, I was destined to begin my winter's schooling somewhat earlier than we had expected, for, five days after the storm, Uncle Tom received from his Boston employers a telegram, forwarded by mail from the end of the line, saying, "Come here at once. Important," when, without demur, he forthwith packed up his things and away he went; while I, taking leave of our kind host, the assayer, moved up to Herr Bergen's house.

I need not go into the details of our daily life on Mosby Creek; it is enough to say that the winter was one of the pleasantest I had ever spent. Time flew by, as was only natural, for there was not an idle moment for either of us. Herr Bergen proved to be a most able instructor, not only in the matter of scholarship but in general training as well. He had served in the German army in his younger days, and the habits of orderliness, precision and promptness remained with him. We boys were made to toe the mark, and no mistake; there was a time for work and a time for play, and whether for duty or pleasure, we had to be on hand to the minute.

I do not wish to imply that the professor was harsh, or anything of the sort; very far from it: he was most considerate of our shortcomings, which were doubtless plentiful enough, and with infinite patience would go over the ground again and again whenever Dick or I got ourselves tangled up; a condition of things which happened on the average about once a day to each of us. Then, every marked advance we made in any of our studies was so obviously gratifying to the kindly old gentleman that that fact alone was enough to spur a fellow on to doing his extra-best. As a consequence, I, for my part, made very notable progress, and it was with great pleasure, as you may suppose, that I was able later on to write to Uncle Tom my conviction that I had gained rather than lost by my winter's work.

One thing, at least, which I should not have acquired in school, I gained by my association with the professor's household: I learned to speak Spanish. Herr Bergen made a great point of it that I should do so, as it would be pretty sure to come in useful during the ensuing summer. He and Dick—and Romero, of course—all spoke it very well, so that my opportunity for picking it up was excellent, and I made rapid progress; my knowledge of Latin, which, though very far from profound, was up to the average of a schoolboy of my age, being an immense help.

All this time we did not lack exercise—the professor was just as particular about that as he was about our work—and Dick and I had many a jolly outing on our snow-shoes, the management of which was another thing I learned. I should not omit to mention also that I spent a good deal of time and a liberal number of cartridges practising with a rifle, thereby becoming a very fair shot; though, of course, I could not compete with Dick, who, having learned as a mere child, seemed, almost, to shoot straight by nature.

The weather on the average was splendid that winter, and there were but few days when we could not get out. Four or five times, perhaps, during the months I spent in the valley a snow-storm came raging down on us, shutting us up for a day or two, after which the jovial sun would turn up smiling again just as though nothing had happened.

It was toward the end of April that Dick and I began to get ready to leave. The increasing power of the sun had cleared off all the snow below eleven thousand feet, the green grass was beginning to show in many places, and it was fair to suppose that by the time we reached the Dos Hermanos we should find pasturage enough for our animals—two ponies and a mule.

Dick already had his own pony, while the mule, a tough little beast by name Uncle Fritz, was provided by the professor, both animals having passed the winter on a ranch about a couple of thousand feet lower down. Before he left, Uncle Tom had suggested hiring them for the season, but the professor would not consent to his paying anything, saying that the animals might just as well be put to some use as to waste their time doing nothing all summer. Consequently, about the only expense to which my guardian was put, besides furnishing provisions and tools for the expedition, was the purchase of a pony and a rifle for me. This was a very moderate outlay, and I was glad to think that Uncle Tom would get off so cheaply, if our search should turn out a failure; and no one was more ready to recognize that possibility—probability, I should rather say, perhaps—than Uncle Tom himself, to whom the many stories in general circulation of lost Spanish mines of fabulous richness were familiar, and who knew very well how little foundation there was for most of them. The present case, though, was different from the generality, in that there existed documentary evidence that there had been such a mine; a fact which altered the conditions entirely. For it is safe to say that without such documentary evidence Uncle Tom would never have consented to our undertaking such an enterprise, and Dick and I, in consequence, would never have run into the series of adventures which were destined to befall us before we were many weeks older.

It was on the first day of May that we at last took leave of our good friend, Herr Bergen, and rode off down the valley, passing on our way through the town of Mosby, where our appearance on horseback, driving our pack-mule before us, excited among the citizens much speculation as to our destination; a matter concerning which we had said not a word to anybody. That it was a prospecting expedition any one could see, for the pick and shovel could not very well be concealed, but where we were bound for nobody knew, Uncle Tom having cautioned us that if we let a word escape about an old Spanish mine we should have a hundred men at our heels in no time; the very idea of such a thing having an irresistible fascination for some people, especially for the inexperienced newcomer.
