Next moment he was studying their faces, and at once he demanded the most important fact. They told him, and before they had finished he was half-way into another suit. He was all eagerness; but somehow the three were very glad to be inside the cube again, and firmly insisted upon moving to another spot before making further explorations.
Within a minute or two the cube was hovering opposite the upper floor of the building the three had entered; and with only a foot of space separating the window of the sky-car and the dust-covered wall, the men from the earth inspected the interior at considerable length. They flashed a search-light all about the place, and concluded that it was the receiving-room, where the raw iron billets were brought via the elevator, and from there slid to the floor below. At one end, in exactly the same location as the desk Smith had destroyed, stood another, with a low and remarkably broad chair beside it.
So far as could be seen, there were neither doors, window-panes, nor shutters through the structure. "To get all the light and air they could," guessed the doctor. "Perhaps that's why the buildings are all triangular; most wall surface in proportion to floor area, that way."
A few hundred feet higher they began to look for prominent buildings. Only in forgetful moments did either of them scan the landscape for signs of life; they knew now that there could be none.
"We ought to learn something there," the doctor said after a while, pointing out a particularly large, squat, irregularly built affair on the edge of the "business district." The architect, however, was in favor of an exceptionally large, high building in the isolated group previously noted in the "suburbs." But because it was nearer, they maneuvered first in the direction of the doctor's choice.
The sky-car came to rest in a large plaza opposite what appeared to be the structure's main entrance. From their window the explorers saw that the squat effect was due only to the space the edifice covered; for it was an edifice, a full five stories high.
The doctor was impatient to go. Smith was willing enough to stay behind; he was already joyously examining the strange machine he had found. Two minutes later Kinney, Van Emmon, and Jackson were standing before the portals of the great building.
There they halted, and no wonder. The entire face of the building could now be seen to be covered with a mass of carvings; for the most part they were statues in bas relief. All were fantastic in the extreme, but whether purposely so or not, there was no way to tell. Certainly any such work on the part of an earthly artist would have branded him either as insane or as an incomprehensible genius.
Directly above the entrance was a group which might have been labeled, "The Triumph of the Brute." An enormously powerful man, nearly as broad as he was tall, stood exulting over his victim, a less robust figure, prostrate under his feet. Both were clad in armor. The victor's face was distorted into a savage snarl, startlingly hideous by reason of the prodigious size of his head, planted as it was directly upon his shoulders; for he had no neck. His eyes were set so close together that at first glance they seemed to be but one. His nose was flat and African in type, while his mouth, devoid of curves, was simply revolting in its huge, thick-lipped lack of proportion. His chin was square and aggressive; his forehead, strangely enough, extremely high and narrow, rather than low and broad.
His victim lay in an attitude that indicated the most agonizing torture; his head was bent completely back, and around behind his shoulders. On the ground lay two battle-axes, huge affairs almost as heavy as the massively muscled men who had used them.
