Ralph smiled in an entirely efficient and satisfying manner.

“Oh, I expect you take the young man too seriously, Mrs. Burton. All boys have cranks of one kind or another, though I must confess Billy’s do not seem to be the ordinary kind. Don’t worry any more; I’ll find him for you and bring him home by the ear. Oh, I don’t mean literally; only from what you have told me I expect the youth takes himself too seriously. He has been ill so much he is probably more or less spoiled. I think the influence of an older fellow may do him good. I am accustomed to taking kinks out of the younger boys at college now and then, when they suffer from swell heads.”

Ralph spoke in a condescending, elderly brother tone which amused Mrs. Burton, although she showed no sign of it. Instead, she gave a little sigh of relief.

“But please be careful, won’t you, Ralph,” she added. “Billy isn’t like other people and he does have to be treated a little differently. Oh, I know you men don’t think this of each other, and Billy’s father will not consider the idea for a moment. But I think if he had talked to Billy more frankly, and asked him to wait a while before he decided so many questions for himself, the boy would not be so difficult.

“Let’s go back now, Ralph, as we have talked over the situation and said as much as there is to say. I don’t suppose you can do anything immediately; but, if, within the next few days you make any kind of discovery, suppose you let me know first. I really am worried over Billy’s realizing I have tried to spy upon him. I should have been dreadfully angry with any one who had done the same thing to me when I was his unreasonable age.”

“Oh, I don’t think Billy will have anything to complain of,” Ralph replied, as if Billy’s attitude held not the slightest interest for him. “And I don’t think I need be forever tracing the young person either—not if he has fallen in with the group Peggy and I met.

“Fortunately, I know where they can be found if they have not disappeared from their camping place. But what there can be in those fellows to interest a youngster, I can’t see.

“I wonder if your man will lend me a burro? I walked over from my hotel, and I think I’ll start out on the trail at once.”

Ralph was really interested in his quest. There was an agreeable element of mystery in it as well as knight errantry. Besides, an older fellow is seldom averse to making a younger one feel small, when he happens to think it good for him. Moreover, Ralph had been considerably out of sorts with himself for several days and it is always pleasanter to dwell on another’s shortcomings.

As soon as Mr. Simpson had allowed him the use of one of the camp ponies for the day, Ralph started off at a leisurely pace.
