Under the Tonto Rim by Zane Grey

Congenial work with happy, eager, simple people made the days speed by so swiftly that Lucy could not keep track of them.

She let six weeks and more pass before she gave heed to the message Clara sent from the school-house by the Claypool children. From other sources Lucy learned that Clara was the best teacher ever employed by the school board. She was making a success of it, from a standpoint of both good for the pupils and occupation for herself.
