Tarzan the Terrible by Edgar Rice Burroughs

Jane had made her first kill and she was very proud of it. It was not a very formidable animal -- only a hare; but it marked an epoch in her existence. Just as in the dim past the first hunter had shaped the destinies of mankind so it seemed that this event might shape hers in some new mold. No longer was she dependent upon the wild fruits and vegetables for sustenance. Now she might command meat, the giver of the strength and endurance she would require successfully to cope with the necessities of her primitive existence.

The next step was fire. She might learn to eat raw flesh as had her lord and master; but she shrank from that. The thought even was repulsive. She had, however, a plan for fire. She had given the matter thought, but had been too busy to put it into execution so long as fire could be of no immediate use to her. Now it was different -- she had something to cook and her mouth watered for the flesh of her kill. She would grill it above glowing embers. Jane hastened to her tree. Among the treasures she had gathered in the bed of the stream were several pieces of volcanic glass, clear as crystal. She sought until she had found the one in mind, which was convex. Then she hurried to the ground and gathered a little pile of powdered bark that was very dry, and some dead leaves and grasses that had lain long in the hot sun. Near at hand she arranged a supply of dead twigs and branches -- small and large.
