Tarzan and the Jewels of Opar (Electronic book text)

Moved by these vague yet all-powerful urgings the ape-man lay awake one night in the little thorn boma that protected, in a way, his party from the depredations of the great carnivora of the jungle. A single warrior stood sleepy guard beside the fire that yellow eyes out of the darkness beyond the camp made imperative. The moans and the coughing of the big cats mingled with the myriad noises of the lesser denizens of the jungle.
