The Book of Camp-Lore and Woodcraft by Daniel Carter Beard

When the "what-is-its" of Pithecantropus erectus age and other like hob-goblin men were moping around the rough sketch of an earth, there were no camp-fires; the only fire that these creatures knew was that which struck terror to their hearts when it was comited forth from volcanic craters, or came crashing among them in the form of lightning. No wonder that the primitive men looked upon fire as a deity, no doubt an evil deity at firdt but one who later became good.

When the vast fields of ice covered Europe during the glacier period and forced men to think or die, necessity developed a prehistoric Edison among the Neanderthal men, who discovered how to build and control a fire, thus saving his race from being frozen in the ice and kept on cold storage, like the hairy rhinoceros and elephant of Siberia.
