He assented very heartily and began to speak of the arms that we had and of the manner of employing them. His fellows, I learned, were bivouacked in the great hall, and these he waked first while I was getting the sleep out of my eyes and asking myself, "What next?" The room in which I lay was Czerny's own room; and now in the daylight the sea played cool and green upon the arched windows and showed to me such sights on the rocks without as I had never dreamed of in the darker hours. What genius had pitched upon such a house under the waves? I asked. What spirit of evil breathed upon this dreadful place? What craving for solitude sent this master-mind here to the bed of the Pacific Ocean, where it could spy upon these uncanny secrets, watching the still green water, face to face with devilish shapes butting upon the glass, the friend of the horrid creatures which slimed upon the windows and crawled to their rocky haunts, or fought claw to claw in the sight of their enemy, man? Desperate as the plight was, I must stand a minute before the crystal panes and watch that changing spectacle of the sea's own wonders. The very water was so near that I thought I had but to stretch out a hand to touch it. The weird, wild things that crept over the rocks, surely they would enter this room presently! And Czerny could live here, cheek by jowl with these fearsome mysteries! Again I say that man knows little of his fellow-man, of his better nature or his worse. _The same day. At five o'clock._ We open the lower doors and go down into the galleries. Seven men are with me and each carries a musket. The quest is not so much for those shut down in the pit as for the life which they may send up to us. Doctor Gray has put it in a word, and it is true. The great engine, which draws the air from the sea's brink and drives it out in life-giving currents through the corridors of Czerny's house, that engine alone stands between us and eternity this day. If those below have kept that engine going until this time, it is for their own safety's sake. Rob them of food and drink, and what security have we that they will continue at the task? And yet, the deed be my witness, it was a perilous journey. No man in our company could say surely how many of Czerny's crew he would find in the black labyrinth we must face. No man could speak of the hidden mysteries lurking in passage or cavern, far from the sea-gate and the sun's light. We were going into the unknown; and we went with timorous steps, each asking himself, "Shall I live to see the day again?" each saying to the other, "Stand close!"
