Roland Clewe remained on the bridge until he had reached its western end, far out on the old Jersey flats, and there he took a car of the suspended electric line, which would carry him to his home, some fifty miles in the interior. The rails of this line ran along the top of parallel timbers, some twenty feet from the ground, and below and between these rails the cars were suspended, the wheels which rested on the rails being attached near the top of the car. Thus it was impossible for the cars to run off the track; and as their bottoms or floors were ten or twelve feet from the ground, they could meet with no dangerous obstacles. In consequence of the safety of this structure, the trains were run at a very high speed. Roland Clewe was a man who had given his life, even before he ceased to be a boy, to the investigation of physical science and its applications, and those who thought they knew him called him a great inventor; but he, who knew himself better than any one else could know him, was aware that, so far, he had not invented anything worthy the power which he felt within himself. After the tidal wave of improvements and discoveries which had burst upon the world at the end of the nineteenth century there had been a gradual subsidence of the waters of human progress, and year by year they sank lower and lower, until, when the twentieth century was yet young, it was a common thing to say that the human race seemed to have gone backward fifty or even a hundred years. It had become fashionable to be unprogressive. Like old furniture in the century which had gone out, old manners, customs, and ideas had now become more attractive than those which were modern and present. Philosophers said that society was retrograding, that it was becoming satisfied with less than was its due; but society answered that it was falling back upon the things of its ancestors, which were sounder and firmer, more simple and beautiful, more worthy of the true man and woman, than all that mass of harassing improvement which had swept down upon mankind in the troubled and nervous days at the end of the nineteenth century. On the great highways, smooth and beautiful, the stage-coach had taken the place to a great degree of the railroad train; the steamship, which moved most evenly and with less of the jarring and shaking consequent upon high speed, was the favored vessel with ocean travellers. It was not considered good form to read the daily papers; and only those hurried to their business who were obliged to do so in order that their employers might attend to their affairs in the leisurely manner which was then the custom of the business world.
