the water was ankle deep, and that the men were nervous was quite evident. Entirely unaccustomed to water except in quantities sufficient for drinking and bathing purposes the red Martians instinctively shrank from it in such formidable depths and menacing activity. That they were undaunted while it swirled and eddied about their ankles, spoke well for their bravery and their discipline.
I was the last to leave the chamber of the submarine, and as I followed the rear of the column toward the corridor, I moved through water to my knees. The corridor, too, was flooded to the same depth, for its floor was on a level with the floor of the chamber from which it led, nor was there any perceptible rise for many yards.
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
