the boy had thought of himself only as Glen Eddy.

The master mechanic of the Brimfield Mills, for such Luke Matherson now was, had meant to keep the secret of the boy's life to himself, at least for some years longer. Glen had, however, heard rumors of it, and had on one occasion been taunted by an angry playmate with the sneer that he was only a nobody who didn't belong to anybody, anyhow.

Glen had promptly forced this tormentor to acknowledge that he did not know what he was talking about; but the taunt rankled all the same. A few days afterwards, which happened to be the one that was kept as his seventeenth birthday, he told his father of it, and asked what it meant.

Then Luke Matherson, greatly troubled, but seeing that the secret could not be kept any longer from the boy, told him what he knew of his history. He ended with, "It is fifteen years ago this very day, Glen, that the terrible wreck took place; and, as you were then thought to be about two years old, I have called this your birthday ever since."

The boy was amazed and bewildered. No idea that the one whom he had always called "father" was not such in reality had ever entered his head; but now that the truth was told him, it seemed strange that he had not always known it instinctively. He had known that Mrs. Matherson was not his own mother, for he was five years old when she assumed that position, and of course he had always known that the two children were not his own sisters, though he loved them as dearly as though they were. But now to find out that he did not really belong to anybody was hard.

Who were his real parents? Were they alive? Could he find them? were questions that now began to occupy the boy's mind most of the time.

One of the strangest things about this state of affairs was to discover that his birthday was not his birthday after all. It seemed as though some foundation on which he had rested in absolute trust of its security had suddenly been swept from under him, and left him struggling in a stormy sea of uncertainty.

The idea of a boy without a birthday! Who ever heard of such a thing? How the other fellows would stare and smile if they knew it! Glen had been so proud of his birthday, too, and it had been made so much of at home. His favorite dishes were always prepared for the meals of that day, his tastes were consulted in everything that was done, and his father always made a point of giving him a more valuable present then than even at Christmas. Why, on the last one, the very day on which the boy first learned how unreal the whole thing was, his father—no, his adopted father—had given him the dearest little silver watch that ever was seen.

Many times since learning such a sad lesson in the uncertainties of life, Glen had pulled this watch from his pocket, simply to assure himself of its reality, and that it was not a make-believe like his birthday.

But for his natural force of character and sweetness of disposition, Glen would have been a spoiled boy; for Luke Matherson had never been able, since the moment he first saw him lying helplessly on the floating car seat, to cross him in anything, or deny him whatever he asked if it lay in his power to grant it. With his own children Mr. Matherson was rather strict; but with the orphan lad who had shared with him the greatest peril of his life, he could not be.

Thus Glen had grown up to be somewhat impatient of restraint, and very much inclined to have his own way. He was also a brave, generous boy, and an acknowledged leader among his young companions. Was he not the best swimmer, the fastest runner, the most daring climber, and expert horseback-rider in Brimfield? Was he not captain of the baseball nine? and did not all the fellows admire him except one or two, who were so jealous of his popularity that they sought to detract from it?

One of those who were most envious of him was Binney Gibbs, son of the wealthy owner of the Brimfield Mills. He was taller than Glen, but was no match for him in anything that called for muscle or pluck. It was he who had flung the taunt of Glen's being a nobody at the boy. Binney had never been noted for his studious habits until both he and Glen entered the High School at the same time. Then, realizing that he could not excel at anything else, he determined to beat the other at his studies. To this end he strained every nerve with such effect that he not only outranked Glen in his own class, but, by working all through two long vacations, gained a whole year on him. So now, while poor Glen was threatened with being turned back from the second class, Binney Gibbs had just graduated at the head of the first, and was ready to enter college. And the worst of it all was that everybody believed him to be a whole year younger than Glen, too.

To be sure, Binney was pale and thin, and no stronger than a cat. Why, he couldn't even swim; but what of it? Had he not beaten the most popular fellow in town away out of sight in this scholarship race? To crown his triumph another thing had happened to make Binney Gibbs the envy of all the boys in Brimfield, but particularly of Glen Eddy.

On that last day of school the diplomas had been awarded, and Binney's had been handed to him the first of all. As he was about to return to his seat, amid the loud applause of the spectators, Mr. Meadows asked him to wait a minute. So Binney stood on the platform while the principal told of a wonderful exploring expedition that was being fitted out at that moment, to go across the plains through the almost unknown territories of New Mexico and Arizona to California. It was to be the most famous expedition of the kind ever sent into the far West; and, as it was to be partly a government enterprise, all sorts of political influence was being used to obtain positions in it. It was to be commanded by a noted general, who was an old friend of Mr. Meadows.

"Now," said the principal, "the general writes that he will give a position in this party to the boy who stands highest in my school this year, or, if I cannot recommend him, or he does not choose to accept it, to any other whom I may name." Here Mr. Meadows was interrupted by prolonged applause.

When it had subsided, he continued. "There is no question as to which pupil of the school ranks highest this year. He stands before you now, with his well-earned diploma in his hand [applause], and it gives me great pleasure to be able to offer to Master Binney Gibbs a position in the exploring-party that will start from St. Louis two weeks from to-day, under command of my friend General Lyle. I hope that he may be induced to accept it, and that his parents may permit him to do so; for I cannot imagine a more fascinating or profitable way of spending a year at his time of life."

Chapter IV.

"I JUST HATE TO STUDY."

Mr. Meadows's remarks in regard to the famous exploring expedition, about to be sent across the Western plains, were received with tremendous applause, and Binney Gibbs at once became an object of envy to every boy in the school—to say nothing of the girls. What a chance to have offered one just for doing a little hard study! If the other boys had known of it, how they, too, would have studied! Binney Gibbs would have been obliged to work harder than he had for his position! Yes, sir! ten times harder!—only think of it! Indians and buffalo and bears, and the Rocky Mountains, and all the other enchanted marvels of that far-away region. Why, just to contemplate it was better than reading a dime novel!

While these thoughts were racing through the minds of his companions, and while they were cheering and clapping their hands, the lucky boy himself was talking with Mr. Meadows, and telling him how much he should like to join that expedition, and how he hoped his father would let him do so.

Mr. Gibbs left his seat in the audience and stepped up to the platform, where he talked for a moment with Mr. Meadows.
