Tarzan, Lord of the Jungle by Edgar Rice Burroughs

Three days crawled slowly out of the east and followed one another across the steaming jungle and over the edge of the world beyond. For three days the Arab moved slowly northward toward el-Habash. For three days Tarzan of the Apes lay in the little clearing, bound and helpless, while Tantor the elephant stood guard above him. Once each day the great bull brought the ape-man food and water.

The camel leather thongs held securely and no outside aid appeared to release Tarzan from the ever increasing discomfort and danger of his predicament. He had called to Manu the monkey to come and gnaw the strands apart, but Manu, ever irresponsible, had only promised and forgotten. And so the ape-man lay uncomplaining, as is the way of beasts, patiently waiting for release, knowing that it might come in the habiliment of death.
