"So I am; but I didn't know I was to be left here."
"That is not exactly what will be done, although it amounts to much the same thing. I propose to have you get on the train with us, as if you were going off, and then, stopping at the next station, travel back thirty or forty miles to whichever town we may decide upon as the most promising."
"What am I to do there, sir?"
"Look for Bob. Move about from town to town just as seems best at the moment, and I have no doubt but that you will soon strike his trail."
"Am I to let you know when I find it?"
"Certainly. Can you write?"
"Yes, sir."
"Then let me hear from you every day. Here is an address where the letters will reach me at the earliest possible moment."
"But, Mr. Harvey, can't you tell me how to begin the work?"
"No; circumstances must decide. I have no question but that you will succeed finally, and in two weeks, if the job isn't finished before, I hope to be with you again."
