The Fourth R by George O. Smith

If Paul Brennan found himself blocked in his efforts to find James Holden and the re-created Holden Educator, James himself was annoyed by one evident fact: Everything he did resulted in spreading the news of the machine itself.

Had he been eighteen or so, he might have made out to his own taste. In the days of late teen-age, a youth can hold a job and rent a room, buy his own clothing and conduct himself to the limit of his ability. At ten he is suspect, because no one will permit him to paddle his own canoe. At a later age James could have rented a small apartment and built his machine alone. But starting as young as he did, he was forced to hide behind the cover of some adult, and he had picked Mrs. Bagley because he could control her both through her desire for security and the promise of a fine education for the daughter Martha Bagley.
