As a scholar traveling in Time he had been accepted by his fellow travelers as a man of great courage and firm determination. For twenty-seven days a smooth surface of shining metal had walled him in, enabling him to grapple with reality on a completely adult level. For twenty-seven days he had gone pridefully back through Time, taking creative delight in watching the heritage of the human race unroll before him like a cineramoscope under glass. Watching a green land in the dying golden sunlight of an age lost to human memory could restore a man's strength of purpose by its serenity alone. But even an age of war and pestilence could be observed without torment from behind the protective shields of the Time Machine. Danger, accidents, catastrophe could not touch him personally.

He had developed a fear of Time. There was no escape from that Time Fear. The instant it came upon him he lost all interest in historical research. 1069, 732, 2407, 1928—every date terrified him. The Black Plague in London, the Great Fire, the Spanish Armada in flames off the coast of a bleak little island that would soon mold the destiny of half the world—how meaningless it all seemed in the shadow of his fear! Had the human race really advanced so much? Time had been conquered but no man was yet wise enough to heal himself if a stark, unreasoning fear took possession of his
