Clarence Young was a house pseudonym used by the Stratemeyer Syndicate for series of books for boys, the most well-known being the "Motor Boys" series.
Underneath was a lot of reading matter, which, as the boys hastily perused it, they saw was an account of the robbery of Mr. Slades store, and a description of Noddy, who, it was stated, had been kidnapped by a gang of river thieves. A reward of $500 was offered for the arrest and conviction of the thieves, while Mr. Nixon offered to pay a like sum for the return of his son. The posters were signed by Chief Dalton.
