Before long Walker's fascination had developed into a bad case of fright. He took the most extraordinary precautions at each of the nightly camps, always clearing away whatever vegetation he found, and avoiding stony places whenever he could. Every clump of stunted bushes and every cleft in the great, slab-like rocks seemed to him now to hide malevolent serpents, while every human figure not obviously part of a settlement or emigrant train seemed to him a potential snake-god till nearness had proved the contrary. Fortunately no troublesome encounters came at this stage to shake his nerves still further. As they approached the Kickapoo country they found it harder and harder to avoid camping near rocks. Finally it was no longer possible, and poor Walker was reduced to the puerile expedient of droning some of the rustic anti-snake charms he had learned in his boyhood. Two or three times a snake was really glimpsed, and these sights did not help the sufferer in his efforts to preserve composure. * * * * * On the twenty-second evening of the journey a savage wind made it imperative, for the sake of the mules, to camp in as sheltered a spot as possible; and Audrey persuaded her husband to take advantage of a cliff which rose uncommonly high above the dried bed of a former tributary of the Canadian River. He did not like the rocky cast of the place, but allowed himself to be overruled this once; leading the animals sullenly toward the protecting slope, which the nature of the ground would not allow the wagon to approach. Audrey, examining the rocks near the wagon, meanwhile noticed a singular sniffing on the part of the feeble old dog. Seizing a rifle, she followed his lead, and presently thanked her stars that she had forestalled Walker in her discovery. For there, snugly nested in the gap between two boulders, was a sight it would have done him no good to see. Visible only as one convoluted expanse, but perhaps comprising as many as three or four separate units, was a mass of lazy wriggling which could not be other than a brood of new-born rattlesnakes. Anxious to save Walker from a trying shock, Audrey did not hesitate to act, but took the gun firmly by the barrel and brought the butt down again and again upon the writhing objects. Her own sense of loathing was great, but it did not amount to a real fear. Finally she saw that her task was done, and turned to cleanse the improvised bludgeon in the red sand and dry, dead grass near by. She must, she reflected, cover the nest up before Walker got back from tethering the mules. Old Wolf, tottering relic of mixed shepherd and coyote ancestry that he was, had vanished, and she feared he had gone to fetch his master.
