She searched for him. He was in none of the expected places; the dank fields were as empty as the house. She turned back to the ditch; from its high bank she could see farther into the shadowy places of the bottom. Travis, meanwhile, had been leisurely pursuing his evening beat. He had overtaken one of his fellow-watchmen, on foot, walking to town, had lent him his horse for the last two miles to camp, and invited him to help himself to what he could find for supper, without waiting for his host. “It is a still night,” said Travis; “I'll mog along slowly up the ditch, and put in a little extra listening: it's at night the water talks.” Long after the rider had passed on, the tread of his horse's hoofs was heard, diminishing on the hard-tramped bank; a loosened stone rattled down and splashed into the water; the wind rustled in the tule-beds; then all surface sounds ceased, and the only talker was the ditch, chuckling and dawdling like an idle child on its errand, which it could not be persuaded to take seriously, to the desert lands. Travis came to the ticklish spot near the bridge, and stopped to listen. Here the ditch cut through beds of clean sand, where the water might sink and work back into the old ground, the sand holding it like a sponge, till all the bottom became a bog, and the banks sank in one wide-spread, general wash-out. The first symptom of such deep-seated trouble would be the water's motion in the ditch,--whirling round and round as if boring a hole in the bottom. Travis laid his ear to the current, for he could judge of the water's movement by the sound. All seemed right at the bridge, but far up the ditch he was aware of a new demonstration. He listened awhile, and then walked on with long, light steps and gained upon the sound, which persisted, defining itself as a muffled churning at marked intervals, with now and then a wait between. The prodding was of some tool at work under water, at the ditch-bank. He crossed to the upper side, and moved forward cautiously along the ridge, crouching that his figure might not be seen against the sky. Nancy had gone up the cow-trail, past the low grounds, and was just climbing the bank when a dark shape, of man or beast, crashed down the opposite slope and shot like a slide of rock into the water. A half-choked cry followed the plunge, then ugly sounds of a scuffle under the ditch-bank--men breathing hard, sighing and snorting; and somebody gasped as if he were being held down till his breath was gone. “Get in there, you old muskrat! You shall stop your own breaks if it takes your cursed carcass to do it! Now then, have you got your breath?” Nancy stayed only to hear a voice that was her father's, convulsed with terror and the chill of his repeated duckings, begging to be spared the anguish of drowning by night in three feet of ditch-water. “Mr. Travis,” she screamed, “you let my father be, whatever you are doing to him! Father, you come right home and get on dry clothes!”
