The march of the troops through the corridor was as rapid as was consistent with the number of men that moved through so narrow a passage, but it was not ample to permit us to gain appreciably on the pursuing tide. As the level of the passage rose, so, too, did the waters rise until it soon became apparent to me, who brought up the rear, that they were gaining rapidly upon us. I could understand the reason for this, as with the narrowing expanse of Omean as the waters rose toward the apex of its dome, the rapidity of its rise would increase in inverse ratio to the ever-lessening space to be filled.

Long ere the last of the column could hope to reach the upper pits which lay above the danger point I was convinced that the waters would surge after us in overwhelming volume, and that fully half the expedition would be snuffed out.

As I cast about for some means of saving as many as possible of the doomed men, I saw a diverging corridor which seemed to rise at a steep angle at my right. The waters were now swirling about my waist. The men directly before me were quickly becoming panic-stricken. Something must be done at once or they would rush forward upon their fellows in a mad stampede that would result in trampling down hundreds beneath the flood and eventually clogging the passage beyond any hope of retreat for those in advance.

Raising my voice to its utmost, I shouted my command to the dwars ahead of me.

"Call back the last twenty-five utans," I shouted. "Here seems a way of escape. Turn back and follow me."

My orders were obeyed by nearer thirty utans, so that some three thousand men came about and hastened into the teeth of the flood to reach the corridor up which I directed them.

As the first dwar passed in with his utan I cautioned him to listen closely for my commands, and under no circumstances to venture into the open, or leave the pits for the temple proper until I should have come up with him, "or you know that I died before I could reach you."

The officer saluted and left me. The men filed rapidly past me and entered the diverging corridor which I hoped would lead to safety. The water rose breast high. Men stumbled, floundered, and went down. Many I grasped and set upon their feet again, but alone the work was greater than I could cope with. Soldiers were being swept beneath the boiling torrent, never to rise. At length the dwar of the 10th utan took a stand beside me. He was a valorous soldier, Gur Tus by name, and together we kept the now thoroughly frightened troops in the semblance of order and rescued many that would have drowned otherwise.

Djor Kantos, son of Kantos Kan, and a padwar of the fifth utan joined us when his utan reached the opening through which the men were fleeing. Thereafter not a man was lost of all the hundreds that remained to pass from the main corridor to the branch.

As the last utan was filing past us the waters had risen until they surged about our necks, but we clasped hands and stood our ground until the last man had passed to the comparative safety of the new passageway. Here we found an immediate and steep ascent, so that within a hundred yards we had reached a point above the waters.
