The final conclusion to which Constans arrived was that he had only to avoid the immediate neighborhood of the Palace Road and the Citadel Square to pursue his investigations with entire safety. Accordingly he grew venturesome, and began to go out-of-doors at all hours of the day or night. And then on the fourteenth day after his arrival in the city his immunity came abruptly to an end.
It was early in the forenoon, and Constans was exploring a quarter of the city that lay to the northeast of the Citadel Square. He became interested in the curious, bridgelike structure which spanned the street; enough of it remained standing to show him that it had been designed for overhead traffic, a highway in the air. There were the rails, the signal-boxes, and other mysterious adjuncts of the ancient railways; he had read about them in his books and he recognized them at once.
Now this particular section of the aërial railway must have been a branch line, for it ended abruptly in front of a building of unusual size and consequent importance. Beyond this again could be seen a surface net-work of iron rails converging to the black mouth of a great tunnel—a highway under the earth. Constans felt a lively impulse to push his explorations further. This was evidently a terminal station of the wonderful steel roads of the ancients; within the building itself he might reasonably expect to find some of the old-time engines and wagons with which the traffic had been carried on.
Passing through a central hall of fine proportions, Constans found himself standing under an immense arched structure of stone and iron and glass. The ancient car-shed, so Constans conjectured; then he paused excitedly before a long platform, at which stood a complete train, made up and ready to start.
Constans examined this new find with critical attention. The enormous locomotive-engine, with its driving-wheels that stood higher than a man's head, impressed him mightily, for all that the monster's burning heart had grown cold and its stentor breathing had been hushed forever. He climbed into the cab and wondered hugely at the multiplicity of stopcocks and levers and cabalistically lettered dials. It seemed incredible that the giant could have moved even his own weight, and yet there was his appointed task strung out behind him, fifteen long and heavy vehicles—it was amazing!
Behind the engine came the cars for luggage, piled high with bags and boxes, and then the regular train equipment, a long line of coaches. These last were of the most luxurious pattern—that was plain to see, although the varnish had blistered on the panels and the silken curtains at the windows hung in tatters. The last car of all had clearly been in service as an eating apartment, and fortunately the doors of this coach had been left closed and the windows remained intact. Constans entered and looked about him, noting that the tables still bore their weight of plate and china and napery. Most moving of all was the little nosegay that stood in a tall glass at each cover. But even as he gazed, delighted that the flowers still retained recognizable shape, they broke and crumbled into nothingness.
It was difficult to understand why the train should have been abandoned, it being evident that it had stood here, ready for immediate departure, but the unquestionable fact may serve to emphasize again the suddenness of the final catastrophe. People had simply dropped and forgotten everything. In the extremity of terror civilized man had become a savage, reverting to primeval instincts in preferring his legs to any other means of escape. There was but one thing left for him—to run away.
It was a depressing experience to be standing solitary and alone under these vast arches that had echoed to the tramp of feet innumerable. A sense of his loneliness pressed heavily upon Constans; then, suddenly, he became aware of the presence of a man, who stood leaning against a pillar a short distance away and watched him from under close-knit brows.
The fair hair and frank, kindly face seemed dimly familiar to Constans; and what thighs and breadth of shoulder! The stranger stood little short of gianthood, and Constans would have run small chance against him as man to man. Bitterly he regretted having left his bow behind; even his double-edged hunting-knife was missing from his belt.
The man walked deliberately forward to meet him. Certainly his dress and equipment proclaimed him a Doomsman, and by the same token he must have recognized that Constans was an alien. Yet he smiled and held out his hand as he came up.
