Bronson found that the streets of the city were teeming with people which was not what he had expected from his brief talk with Miss Carlson of Earth Two. Bronson was absolutely certain that this was not Earth Two at all, for it seemed unlike a world teetering on the brink of death--even ignoring the main clincher of the pillar of atomic fire mentioned by La Carlson, there was that vast and more-than-obvious difference. Bronson shook his head in wonder. This was not unlike his own world, yet there were subtle differences--subtle differences observable at first glance, but becoming bold and glaring differences as Bronson became more familiar with the street down which he walked. A bus went past--and did not leave a wake of evil-smelling pale blue exhaust. A store on the corner advertised cigarette lighters which bore the name _Irhinium_. Bronson knew of most of the cigarette lighter companies by name and none of them bore such a name. He looked more carefully and noted that certain vague references to _Irhinium_ indicated that it was a trade name based upon the motive power of the things. In this strange world to which he had been hurled, did they--by the Great Harry--use atomic power to light their cigarettes? Bronson's mind, of course, was overwhelmed by the suddenness of events and its natural inability to accept such a vast conglomeration of new concepts at the same time. It merely watched, saw, cataloged. Anything outrageous would be given the same consideration as something quite normal in Bronson's nervous state of complete wonder. His mental state bordered on shock. Noiselessly the traffic moved, noiselessly and without odor. Dress and appointment were brilliant and entirely new. The overhead wires of Ed Bronson's world were gone, as were the poles that bore them. Nor were there street lights. Streetcars plied their routes with a minimum of thundering racket but there was neither trolley above nor slot in the street below. Bronson paused before a large toy shop and watched a man manipulating an electric train. The miniature train had all the maneuverability of a real train because of the multiplicity of controls under the fingers of the man in the window. Beside the train was a large box containing cubic bits of metal and non-metal. The explanation on the box said that the contents would build a miniature fission-reacting pile that worked but which employed Kenium metal instead of uranium since the use of the latter was dangerous, requiring ton upon ton of fissionable material as well as a moderator. That was the clincher. Bronson's mind cleared once the facts were driven home. He was not on Earth Two. He was most certainly not on Earth One.
