The scene of desolation that met us in the Lone City was at once extraordinary and awesome. It seemed impossible that our rays, acting for so brief a period, could have done so much damage. The city was nothing more than a semicivilized settlement of little, flat‑topped stone houses. Our rays, striking these, had discharged harmlessly into the ground. But the interiors had been penetrated through windows and doors, and everything inflammable about them, as well as about the streets, had been destroyed.

The people had taken refuge in cellars underground and in caves and crevices—wherever they could find shelter. But even so, there were a thousand dead in that city that morning, and rapidly spreading disease would shortly have killed them all. They came out of their hiding places little by little as we entered the streets, and stood about in groups staring at us sullenly. They seemed mostly old men and women and children, the younger men having fled with Tao's army. They were heavy‑set, pathetic people, with broad, heavy faces, pasty‑white skin, and large protruding eyes. We were in the Lone City nearly a month, burying the dead, doing what we could for the people, and destroying or removing the apparatus Tao had left behind him.

The Lone City, before the banishment of Tao, had been one of the most primitive settlements of the Twilight region. It was in the other hemisphere that the Twilight Country was more densely populated; but since this Lone City was so close to the Great City it had become the scene of Tao's exile.

This region about the Lone City was of the most barren of the whole Twilight country. Its people were almost entirely meat eaters. Back toward the Dark Country great bands of animals like caribou roamed. Living almost entirely in darkness, they had little power of sight, and were easy prey to hunters.

Their hides, which were covered with short, white fur, provided clothing; a form of candle was made from their fat, and used for lighting; and their flesh provided food. The Dark City, some two hundred and fifty miles away, was the center from which most of these animals were obtained.

"Then, that's where Tao has been getting his supplies from," Mercer exclaimed, as we heard all this from one of the Twilight People. "And that's where he has gone now."

Tao had indeed withdrawn to the Dark City, we learned positively. And more than that, we learned that he had factories there as well as here. We found in the Lone City some eight of the interplanetary vehicles—most of them almost entirely completed. The fact that Tao had abandoned them so readily made us believe he had others in the Dark City.

There seemed a curious lack of appliances for protection against the ray. This we attributed to two causes—that Tao had managed to take most of them with him, and that his supply of fabric came from distant cities on the other side of the globe. Within a month after we had occupied the Lone City we were again ready to start forward. It had been an irksome month for Mercer, and not a day had passed without my receiving a truculent declaration from him that we were fools to allow Tao to escape so easily.

Our occupation of the Lone City was to continue. On this second expedition farther into the Twilight Country I took with me a much smaller and more select force. We had before us a land journey of some two hundred and fifty miles, through an unknown, barren country, in which it would be difficult for us to maintain ourselves, so I was determined to be burdened with as few men as possible.

Our force consisted of all the older men trained in the operation of the larger projectors and rockets; a variety of mechanics and helpers, men selected for their physical strength; a corps of young men to the number of fifty, and fifty girls.
