Perhaps it _is_ the pavements--but no matter; I am not ordinarily a jumping sort. And yet there was something in the quality of that voice beyond my shoulder that brought the sweat stinging through the pores of my scalp even while I was in the act of turning. A cat sat there on the hatch, expressionless and immobile in the gloom. I did not say anything. I turned and went below. McCord was there already, standing on the farther side of the table. After a moment or so the cat followed and sat on her haunches at the foot of the ladder and stared at us without winking. "I think she wants something to eat," I said to McCord. He lit a lantern and went into the galley. Returning with a chunk of salt beef, he threw it into the farther corner. The cat went over and began to tear at it, her muscles playing with convulsive shadow-lines under the sagging yellow hide. And now it was she who listened, to something beyond the reach of even McCord's faculties, her neck stiff and her ears flattened. I looked at McCord and found him brooding at the animal with a sort of listless malevolence. "_Quick_! She has kittens somewhere about." I shook his elbow sharply. "When she starts, now--" "You don't seem to understand," he mumbled. "It wouldn't be any use." She had turned now and was making for the ladder with the soundless agility of her race. I grasped McCord's wrist and dragged him after me, the lantern banging against his knees. When we came up the cat was already amidships, a scarcely discernible shadow at the margin of our lantern's ring. She stopped and looked back at us with her luminous eyes, appeared to hesitate, uneasy at our pursuit of her, shifted here and there with quick, soft bounds, and stopped to fawn with her back arched at the foot of the mast. Then she was off with an amazing suddenness into the shadows forward. "Lively now!" I yelled at McCord. He came pounding along behind me, still protesting that it was of no use. Abreast of the foremast I took the lantern from him to hold above my head. "You see," he complained, peering here and there over the illuminated deck. "I tell you, Ridgeway, this thing--" But my eyes were in another quarter, and I slapped him on the shoulder. "An engineer--an engineer to the core," I cried at him. "Look aloft, man."
