ook!" cried Brand.

For over an hour the ship had been propelled swiftly, irresistibly toward the center of the red spot. It had been up about forty thousand feet. Now, with a jerk that sent both men reeling, it had been drawn down to within fifteen thousand feet of the surface; and the sight that was now becoming more and more visible was incredible.

Beneath was a vast, orderly checkerboard. Every alternate square was covered by what seemed a jointless metal plate. The open squares, plainly land under cultivation, were surrounded by gleaming fences that hooked each metal square with every other one of its kind as batteries are wired in series. Over these open squares progressed tiny, two legged figures, for the most part following gigantic shapeless animals like figures out of a dream. Ahead suddenly appeared the spires and towers of an enormous city!

Metropolis and cultivated land! It was as unbelievable, on that raw new planet, as such a sight would have been could a traveler in time have observed it in the midst of a dim Pleistocene panorama of young Earth.

It was instantly apparent that the city was their destination. Rapidly the little ship was rushed toward it; and, realizing at last the futility of its laboring, Brand cut off the atomic motor and let the shell drift.

Over a group of squat square buildings their ship passed, decreasing speed and drifting lower with every moment. The lofty structures that were the nucleus of the strange city loomed closer. Now they were soaring slowly down a wide thoroughfare; and now, at last, they hovered above a great open square that was thronged with figures.

Lower they dropped. Lower. And then they settled with a slight jar on a surface made of reddish metal; and the figures rushed to surround them.
