"I camped here two years ago," he said, "An' the cave was alive with rock-rats, mice, snakes, horned-toads, lizards an' a big Gila monster, besides bugs, scorpions' rattlers, an' as fer tarantulers an' centipedes—say! I couldn't sleep fer the noise they made fightin'." "I seen the same," concluded Lawson, as nonchalant as a wild-horse wrangler well could be. "An' as fer me, now I allus lays perfickly still when the centipedes an' tarantulers begin to drop from their holes in the roof, same as them holes up there. An' when they light on me, I never move, nor even breathe fer about five minutes. Then they take a notion I'm dead an' crawl off. But sure, if I'd breathed I'd been a goner!" All of this was playfully intended for the extinction of an unoffending and impressionable tenderfoot. With an admiring glance at my tormentors, I rolled out my sleeping-bag and crawled into it, vowing I would remain there even if devil-fish, armed with pikes, invaded our cave. Late in the night I awoke. The bottom of the cañon and the outer floor of our cave lay bathed in white, clear moonlight. A dense, gloomy black shadow veiled the opposite cañon wall. High up the pinnacles and turrets pointed toward a resplendent moon. It was a weird, wonderful scene of beauty entrancing, of breathless, dreaming silence that seemed not of life. Then a hoot-owl lamented dismally, his call fitting the scene and the dead stillness; the echoes resounded from cliff to cliff, strangely mocking and hollow, at last reverberating low and mournful in the distance. How long I lay there enraptured with the beauty of light and mystery of shade, thrilling at the lonesome lament of the owl, I have no means to tell; but I was awakened from my trance by the touch of something crawling over me. Promptly I raised my head. The cave was as light as day. There, sitting sociably on my sleeping-bag was a great black tarantula, as large as my hand. For one still moment, notwithstanding my contempt for Lawson's advice, I certainly acted upon it to the letter. If ever I was quiet, and if ever I was cold, the time was then. My companions snored in blissful ignorance of my plight. Slight rustling sounds attracted my wary gaze from the old black sentinel on my knee. I saw other black spiders running to and fro on the silver, sandy floor. A giant, as large as a soft-shell crab, seemed to be meditating an assault upon Jones's ear. Another, grizzled and shiny with age or moonbeams I could not tell which—pushed long, tentative feelers into Wallace's cap. I saw black spots darting over the roof. It was not a dream; the cave was alive with tarantulas! Not improbably my strong impression that the spider on my knee deliberately winked at me was the result of memory, enlivening imagination. But it sufficed to bring to mind, in one rapid, consoling flash, the irrevocable law of destiny—that the deeds of the wicked return unto them again.
