An hour went by; an hour and a half. I pressed the attention button to the operating room, and gave orders to reduce our speed by half. We were very close to the outer fringe of the atmospheric envelope. Then, keeping my eye on the big surface-temperature gauge, with its stubby red hand, I resumed my nervous pacing.

Slowly the thick red hand of the surface-temperature gauge began to move; slowly, and then more rapidly, until the eyes could catch its creeping.

"Reduce to atmospheric speed," I ordered curtly, and glanced down through a side port at one end of the long navigating room.

We were, at the moment, directly above the twilight belt. To my right, as I looked down, I could see a portion of the glistening antarctic ice cap. Here and there were the great flat lakes, almost seas, of the planet.

Our geographies of the Universe to-day do not show the topography of the Forgotten Planet: I might say, therefore, that the entire sphere was land area, with numerous great lakes embedded in its surface, together with many broad, very crooked rivers. As Ame Baove had reported, there were no mountains, and no high land.

"Altitude constant," I ordered. "Port three degrees. Stand by for further orders."

The earth seemed to whirl slowly beneath us. Great cities drifted astern, and I compared the scene below me with the great maps I took from our chart-case. The Control City should be just beyond the visible rim; well in the daylight area.

"Port five degrees," I said, and pressed the attention button to Barry's quarters.

"Mr. Barry, please call all men to quarters, including the off-duty watch, and then report to the navigating room. Mr. Eitel will be under my direct orders. We shall descend within the next few minutes."

"Very well, sir."
