Just then their conversation was interrupted by the arrival of a visitor, who, to Glen's surprise, was none other than Mr. Hobart, the engineer whose position he had been thinking of as one of the most desirable in the world.

After a few moments' pleasant chat the visitor asked Mr. Matherson if he could have a private business talk with him. So Glen left the room, and wandered restlessly about the house, filled with a lively curiosity as to what business the engineer could have with his adopted father.

In the meantime Mr. Hobart was saying, "I have known your son for some time by sight, Mr. Matherson, and took a fancy to him from the first. We only got acquainted to-day, when he performed an act of daring in my presence, and at the same time rendered me an important service. I find him to be exactly such a boy as I supposed he was; a generous-hearted, manly fellow, who is just now unhappy and discontented because he has no particular aim in life, and does not know what he wants to do."

"Yes," said Mr. Matherson, "that is just the trouble; and the worst of it is that I don't know what to advise him."

"Then, perhaps, I am just in time to help you. My work here is about finished, and in a few days I am to leave for Kansas, where I am to take charge of a locating-party on one of the Pacific railroads. If you are willing to let Glen go with me, I can make a place for him in this party. The pay will only be thirty dollars per month, besides his expenses; but, by the end of the summer, I believe he will have gained more valuable knowledge and experience than he could in a year of home and school life. I believe, too, in that time I can show him the value of an education and the necessity of studying for it. Now, without really knowing anything about it, he thinks he would like to become a civil-engineer. After a few months' experience in the unsettled country to which I am going he will have seen the rough side of the life, and can decide intelligently whether he desires to continue in it or not."

Mr. Matherson could hardly restrain his delight at the prospect of such an opening for the boy whom he loved so dearly; but he was too honest to let him start out under false colors; so he said,

"I can never tell you how grateful I am for this offer, sir; but I don't want you to think that my boy is any better than he really is. He is not a good scholar, and seems to lack application. Even now he is in danger of being turned back a whole year in school because he has failed to keep up with his class."

"I know all that," replied Mr. Hobart, smiling; "and it is one of the reasons why I want him to go with me. I was very much such a boy myself, and think I understand his state of mind perfectly. He has reached the most trying period of his life, and the one where he most needs encouragement and help. He has a sufficiently good education to build on, and is bright enough to comprehend things that are clearly explained to him. As for his having no knowledge of the peculiar studies necessary for an engineer, I am glad that he hasn't. I believe that it is better for all boys to gain some practical knowledge of the business they intend to follow before they really begin to study for it. A few months or a year of practice shows them in what they are deficient and what they need to learn. I could get plenty of young fellows to go out to Kansas with me who are crammed with theoretical knowledge of surveying and engineering, but who are ignorant of its practice. Such chaps think they know it all, and are impatient of criticism or advice. I can get along better with one who knows little or nothing to begin with, but who is bright and willing to learn. In the end I will guarantee to make such a one the more valuable engineer of the two."

"It is a new idea to me," said Mr. Matherson, reflectively, "but I believe you are right."

"There is another reason why I fancy your boy, and think I can make an engineer of him," continued Mr. Hobart. "His physical condition seems to me to be perfect. As they say of prize animals, he seems to be sound in wind and limb, and without a blemish. Now, the life of an engineer, particularly in unsettled countries, is a hard one. He is exposed to all sorts of weather; must often sleep without a shelter of any kind, and must work hard from early dawn until late at night, sometimes on a scanty allowance of food. It is as hard as, and in many cases harder than, active service in the army. It is no life for weaklings, and we do not want them; but, from what I have seen of your boy, I do not believe that even you can point out any physical defect in his make-up."
