Dorothy and the Wizard in Oz — Chapter 6…
(1908)

Jim had to be careful not to step upon the tiny piglets, who scampered under his feet grunting and squealing, while Eureka, snarling and biting at the thorns pushed toward her, also tried to protect the pretty little things from injury. Slowly but steadily the heartless Mangaboos drove them on, until they had passed through the city and the gardens and come to the broad plains leading to the mountain. ”
