"This must be their city hall, the palace of justice, the main administration building, or whatever they call it," said Jack. "Evidently the Martians don't believe in conducting politics in the dark."

"Well, it's going to be dark pretty soon," observed Mark, "for the sun is setting."

"And look at what a small sun it is," added Jack.

For the first time they noticed that the great luminary was much smaller than it appeared to them on the earth. It was about half the size, but, though Mars must have received considerably less heat from it than did the earth, it was not at all chilly, but, on the contrary, warmer than on the earth at the same time of year.

The little sun slowly sank down behind the distant hills, and when the sleds came to a stop in front of the glass palace, the boys and others found themselves being moved up the broad steps.

"Evidently there's going to be an inquiry concerning us," commented Jack.

They were taken into a vast audience chamber. At one end was a raised platform, upon which were seated a number of Martians. Each one had a golden circlet on his head, and in the center of each band was some geometrical figure.

In the middle of the throng on the platform was a Martian attired in a golden, shimmering robe. And on his head was a small circlet, made apparently of diamonds.

"He must be the high muck–a–muck," said Jack in a whisper.

"Hush!" cautioned Mark.
