"No; far less expensive than horses. The batteries, or accumulators, are very small, but with great power. The weight carried by such a carriage as this, in accumulators, is about fifteen pounds, and the energy is the equivalent of two horses for six hours, or a greater number of horses for a less time. The accumulators are charged at the rate of about fifty cents per set, which is a six-hour run. The great saving is that when the carriage is not in use, there is no expense." The carriage was going at a good round gait, but the motion was easy and steady. Passing into Market street, Cobb was astonished at the magnificence of the buildings. He could not remember ever having seen a single building then standing as being there during his time. The architecture was grand in the extreme; beauty was not lacking, but was combined with strength. He saw horses, electric motors, and cable cars, but the latter no longer ran upon tracks on the street; the trucks were all underneath the roadbed, while the cars were held aloft by thin but strong steel supports. The cars, moreover, were lighter built and set closer to the ground. He saw no horse-cars. The pavement was everywhere of the same material--clean, smooth, and elastic; and he rejoiced to think that at last mankind had awakened to the fact that it was not only cruel, but costly, to cause horses to run upon cobble-stones, and pavements of similar construction. He did not have time to note all the many changes which had taken place and then in view, ere the carriage stopped at the gate of a most imposing edifice. Alighting from his seat, Rawolle assisted him down, saying: "Here we are, Mr. Cobb." Having gotten out, they all went into the depot, for such Cobb was informed it was. He was surprised at the grandeur of the building. It far exceeded anything he had ever seen for similar purposes. Rawolle took him around and showed him the various waiting, toilet, dining, and other rooms. The depot was on the site formerly occupied by the old station, at the corner of Third and Townsend streets. Passing into the main hall, he perceived a stream of people coming from the left. The interior of the depot, after passing through the main hall, was a vast space with a great arched roof. The ground was paved with marble slabs, and divided by iron fencing into five large compartments; the first running from side to side of the building, while the others were set at right angles to it. Each of the four divisions had a great slot or opening through its floor, of about two hundred feet in length by twelve in width. The last opening was filled by a train which had just arrived. The people were flocking out, and through the gates into the main hall, or, as Cobb called it, the fifth compartment. His attention was riveted to the train as it stood upon the track. It was so different from anything in the railway line that he had ever seen before, that he was most anxious to learn something about it.
