In the journeys that Wauna and I took during the college vacation, we were constantly meeting strangers, but they never appeared the least surprised at my dark hair and eyes, which were such a contrast to all the other hair and eyes to be met with in Mizora, that I greatly wondered at it until I learned of the power of the reflector. I requested permission to examine one of the large ones used in a theater, and it was granted me. Wauna accompanied me and signaled to a friend of hers. As if by magic a form appeared and moved across the stage. It bowed to me, smiled and motioned with its hand, to all appearances a material body. I asked Wauna to approach it, which she did, and passed her hand through it. There was nothing that resisted her touch, yet I plainly saw the figure, and recognized it as the perfect representation of a friend of Wauna's, an actress residing in a distant city. When I ascended the stage, the figure vanished, and I understood that it could be visible only at a certain distance from the reflector. In traveling great distances, or even short ones where great speed was desired, the Mizoraens used air ships; but only for the transportation of passengers and the very lightest of freight. Heavy articles could not be as conveniently carried by them as by railroads. Their railroads were constructed and conducted on a system so perfect that accidents were never known. Every engineer had an electric signal attached to the engine, that could signal a train three miles distant. The motive power for nearly all engines was compressed air. Electricity, which was recognized by Mizora scientists as a force of great intensity, was rarely used as a propelling power on railroads. Its use was attended by possible danger, but compressed air was not. Electricity produced the heat that supplied the air ships and railroads with that very necessary comfort. In case there should be an accident, as a collision, or thrown from the track, heat could not be a source of danger when furnished by electricity. But I never heard of a railroad accident during the whole fifteen years that I spent in Mizora. Air-ships, however, were not exempt from danger, although the precautions against it were ingenious and carefully observed. The Mizora people could tell the approach of a storm, and the exact time it would arrive. They had signal stations established for the purpose, all over the country. But, though they were skilled mechanics, and far in advance of my own world, and the limits of my comprehension in their scientific discoveries and appliances, they had not yet discovered the means of subduing the elements, or driving unharmed through their fury. When nature became convulsed with passion, they guarded themselves against it, but did not endeavor to thwart it.
