The streets of Mizora were all paved, even the roads through the villages were furnished an artificial cover, durable, smooth and elastic. For this purpose a variety of materials were used. Some had artificial stone, in the manufacture of which Mizora could surpass nature's production. Artificial wood they also made and used for pavements, as well as cement made of fine sand. The latter was the least durable, but possessed considerable elasticity and made a very fine driving park. They were experimenting when I came away on sanded glass for road beds. The difficulty was to overcome its susceptibility to attrition. After business hours every street was swept by a machine. The streets and sidewalks, in dry weather, were as free from soil as the floor of a private-house would be. Animals and domestic fowls had long been extinct in Mizora. This was one cause of the weird silence that so impressed me on my first view of their capital city. Invention had superceded the usefulness of animals in all departments: in the field and the chemistry of food. Artificial power was utilized for all vehicles. The vehicle most popular with the Mizora ladies for shopping and culling purposes, was a very low carriage, sometimes with two seats, sometimes with one. They were upholstered with the richest fabrics, were exceedingly light and graceful in shape, and not above three feet from the ground. They were strong and durable, though frequently not exceeding fifty pounds in weight. The wheel was the curious and ingenious part of the structure, for in its peculiar construction lay the delight of its motion. The spokes were flat bands of steel, curved outward to the tire. The carriage had no spring other than these spokes, yet it moved like a boat gliding down stream with the current. I was fortunate enough to preserve a drawing of this wheel, which I hope some day to introduce in my own land. The carriages were propelled by compressed air or electricity; and sometimes with a mechanism that was simply pressed with the foot. I liked the compressed air best. It was most easily managed by me. The Mizora ladies preferred electricity, of which I was always afraid. They were experimenting with a new propelling power during my stay that was to be acted upon by light, but it had not come into general use, although I saw some vehicles that were propelled by it. They moved with incredible speed, so rapid indeed, that the upper part of the carriage had to be constructed of glass, and securely closed while in motion, to protect the occupant. It was destined, I heard some of their scientists say, to become universal, as it was the most economical power yet discovered. They patiently tried to explain it to me, but my faculties were not receptive to such advanced philosophy, and I had to abandon the hope of ever introducing it into my own country.
