We walked on and on, until I became convinced that if we had followed the right corridor we should long since have arrived at the entrance. I suggested as much to Pan Dan Chee, and he agreed with me; then we retraced our steps and tried another corridor. We kept this up until we were all but exhausted, but we failed to find the right corridor.

"I am afraid we are lost," said Pan Dan Chee.

"I am quite sure of it," I agreed, with a smile. If we were sufficiently well lost, we might not find the entrance before the next noon; in which event Pan Dan Chee would be free to go where he pleased, and I had a pretty good idea of where he pleased to go.

Now, I am no matchmaker; nor neither do I believe in standing in the way to prevent the meeting of a man and a maid. I believe in letting nature take her course. If Pan Dan Chee thought he was in love with Llana of Gathol and wished to go to Gathol and try to win her, I would only have discouraged the idea had he been a man of low origin or of a dishonorable nature. He was neither. The race to which he belonged is the oldest of the cultured races of Barsoom, and Pan Dan Chee had proved himself a man of honor.

I had no reason to believe that his suit would meet with any success. Llana of Gathol was still very young, but even so the swords of some of the greatest houses of Barsoom had been lain at her feet. Like nearly all Martian women of high degree she knew her mind. Like so many of them, she might be abducted by some impetuous suitor; and she would either love him or slip a dagger between his ribs, but she would never mate with a man she did not love. I was more fearful for Pan Dan Chee than I was for Llana of Gathol.

We retraced our steps and tried another corridor, yet still no entrance. We lay down and rested; then we tried again. The result was the same.

"It must be nearly morning," said Pan Dan Chee.

"It is," I said, consulting my chronometer. "It is almost noon."

Of course I didn't use the term noon; but rather the Barsoomian equivalent, 25 xats past the 3rd zode, which is 12 noon Earth time.

"We must hurry!" exclaimed Pan Dan Chee.

A hollow laugh sounded behind us; and, turning quickly, we saw a light in the distance. It disappeared immediately. "Why should we hurry?" I demanded. "We have done the best we could. That we did not find our way back to the citadel and death is no fault of ours."

Pan Dan Chee nodded. "And no matter how much we may hurry, there is little likelihood that we shall ever find the entrance."
