I was now concerned with fear for myself. The open trap lay directly in his path, and his discovery of it would lead instantly to his discovery of me. I was angry with myself for being caught in so cowardly a position, crouching on the floor. There was yet time. I rose swiftly to my feet, and, I know, quite unconsciously assumed a defiant attitude. He took no notice of me. Nor did he notice the open trap. Before I could grasp the situation, or act, he had walked right into the trap. One foot was descending into the opening, while the other foot was just on the verge of beginning the uplift. But when the descending foot missed the solid flooring and felt vacancy beneath, it was the old Wolf Larsen and the tiger muscles that made the falling body spring across the opening, even as it fell, so that he struck on his chest and stomach, with arms outstretched, on the floor of the opposite side. The next instant he had drawn up his legs and rolled clear. But he rolled into my marmalade and underclothes and against the trap-door. The expression on his face was one of complete comprehension. But before I could guess what he had comprehended, he had dropped the trap-door into place, closing the lazarette. Then I understood. He thought he had me inside. Also, he was blind, blind as a bat. I watched him, breathing carefully so that he should not hear me. He stepped quickly to his state-room. I saw his hand miss the door-knob by an inch, quickly fumble for it, and find it. This was my chance. I tiptoed across the cabin and to the top of the stairs. He came back, dragging a heavy sea-chest, which he deposited on top of the trap. Not content with this he fetched a second chest and placed it on top of the first. Then he gathered up the marmalade and underclothes and put them on the table. When he started up the companion-way, I retreated, silently rolling over on top of the cabin. He shoved the slide part way back and rested his arms on it, his body still in the companion-way. His attitude was of one looking forward the length of the schooner, or staring, rather, for his eyes were fixed and unblinking. I was only five feet away and directly in what should have been his line of vision. It was uncanny. I felt myself a ghost, what of my invisibility. I waved my hand back and forth, of course without effect; but when the moving shadow fell across his face I saw at once that he was susceptible to the impression. His face became more expectant and tense as he tried to analyze and identify the impression. He knew that he had responded to something from without, that his sensibility had been touched by a changing something in his environment; but what it was he could not discover. I ceased waving my hand, so that the shadow remained stationary. He slowly moved his head back and forth under it and turned from side to side, now in the sunshine, now in the shade, feeling the shadow, as it were, testing it by sensation.
