"By George! I hadn't thought of that. I guess he will be, though.
He's usually home in the afternoon."

The boys took the elevated from the South station to the North station, where they found they could catch a train to Woburn, the town where Frank's father lived, in ten minutes.

It was only a little more than ten miles from Boston to Woburn and the trip was made quickly. As they alighted from the train, Frank let his eyes rove over the familiar landmarks, which he had not seen for three years. There was little change to be noticed. Frank led the way toward his home.

He paused before an old-fashioned New England house and Jack, glancing up, saw this sign on the door:

"Dr. R. G. Chadwick."

Frank mounted the steps rapidly and rang the bell. An elderly woman came to the door. Frank had never seen her before.

"Is the doctor in?" he asked.

"Yes, but he is busy right now. Step in and have a seat."

Frank led the way into the doctor's waiting room, where he and Jack sat down.

Frank's mother was dead. She had passed away when the lad was not more than five years, and in the days that followed Dr. Chadwick had been father and mother both to him.
