"How about eating?" suggested the Very Young Man.

They sat down at the base of the incline and ate another meal—rather a more lavish one this time, for the rest they had taken, and the prospect of a shorter journey ahead of them than they had anticipated made the Doctor less strict. Then, the meal over, they took the amount of the drug the Chemist specified. He measured it carefully—more than ten of the pills.

"We have a long wait," the Chemist said, when the first sickness from this tremendous dose had left them.

The time passed quickly. They spoke seldom, for the extraordinary rapidity with which the aspect of the landscape was changing, and the remarkable sensations they experienced, absorbed all their attention.

In about two hours after taking the drug the curving, luminous line that was the upper edge of the incline came into view, faint and blurred, but still distinct against the blackness of the sky. The incline now was noticeably steeper; each moment they saw its top coming down towards them out of the heights above, and its surface smoothing out and becoming more nearly perpendicular.

They were all standing up now. The ground beneath them seemed in rapid motion, coming towards them from all directions, and dwindling away beneath their feet. The incline too—now in form a vertical concave wall—kept shoving itself forward, and they had to step backwards continually to avoid its thrust.

Within another hour a similar concave wall appeared behind them which they could follow with their eyes entirely around the circumference of the great pit in which they now found themselves. The sides of this pit soon became completely perpendicular—smooth and shining.

Another hour and the action of the drug was beginning to slacken—the walls encircling them, although steadily closing in, no longer seemed to move with such rapidity. The pit as they saw it now was perhaps a thousand feet in diameter and twice as deep. Far overhead the blackness of the sky was beginning to be tinged with a faint gray-blue.

At the Chemist's suggestion they walked over near the center of the circular enclosure. Slowly its walls closed in about them. An hour more and its diameter was scarcely fifty feet.

The Chemist called his companions around him.
