“I see,” nodded Ralph; “also where you come in.”

“Yes, that’s easy to guess,” said Fred. “Just at that time I happened to be on a flying visit to Earlville, where one day I met Clark. He took me to the hotel, where I met Ernest. I had known young Gregg before, for he had come to Earlville a ragged, homeless lad before I first left, seeming to have no home or relatives, and going to work at odd jobs around the town. Clark told me of the fix he was in. While we were talking, a sudden idea came to him. He became very much excited and serious, and then made a very strange request of me.”

“To assume his identity and go railroading in his stead?” inquired Ralph, anticipating what was coming. 165

“You’ve struck it,” assented Fred; “just that.”

“And you accepted?”

“And that is why you see me here,” said Fred. “Don’t think any the less of me, Fairbanks, for doing it. Don’t find fault with me if I took up the imposture for all there was in it. It’s my way—when I go at a thing, I do so with all my—nerves. I was Marvin Clark to the core. I took up his name, I played his part, and say, I tried not to disgrace his good name by one unmanly act. He taught me to imitate his handwriting perfectly one day. The next I was on the road, without a mishap until I met you.”

“Which may not be a mishap after all,” suggested the young engineer.

“I think as you do about that. I’ve come to you for advice, and I feel sure that it will be good advice. Now, then, to get to central motive of Clark’s plan—a noble, grand act, a royal deed. It was all for the sake of his little charge, Ernest Gregg.”

“I can imagine that,” said Ralph.

“Clark could not get the little fellow out of his mind. He had got, it seemed, a clew to some of his relatives. He told me that only for a wicked enemy, and if he had his rights, Ernest would be in a position of positive wealth. He said that he was determined to find a certain old man who 166 could clear up the whole situation. He was going to start out with Ernest to solve the secret of his strange life, while his friends supposed that he was following out the plan that his father had arranged. Clark made a plan how we were to keep track of one another, writing to certain points we agreed upon. I started out from Earlville on my part of the arrangement, while Clark stole out of town with his young charge. For three weeks I wrote regularly to him and he replied. During the last month I have not received a word from him, and some of my letters have come back to me.”
