We passed on, and when the valley widened out again we descended and sat down under the oaks to eat our luncheon. It soon disappeared, the last morsel, and we were on our way again. At long intervals farm houses appeared on the edge of the bluff, and in the river below one of them, on the opposite side of the stream from us, was a curious old water-wheel on a flatboat securely moored to the trees on the bank, and which laboriously and noisily jerked water up through a pipe to the bluff above. The meadows along the river are the pasturage of big herds of horses and cattle, and one is lucky if one’s perambulations are not interrupted by some inhospitable bull. As we ascend the river it grows swifter and more rocky and the top of the bluff rolls higher and higher and the hills appear in the distance. When we came to the first of these low hills we climbed the bluff and ascended it. It was a peculiar formation of stone resembling sand in softness or sand resembling stone in hardness, we could hardly determine which. It was seamed and ribbed, projecting cliff-like into the air, with boulders lying about and with caverns and precipitous sides. As we scaled to the top of it we scared away a number of turkey buzzards that had been watching our ascent, and it was evidently their nesting place, as we discovered traces of old nests and a good many bones of the hapless denizens of the plains. We started several of the big boulders at the edge rolling and plunging down, and, though most of them broke up in their downward career, they stopped only when, after a great plunge, they settled in the bed of the river. Sometimes as they thundered down they would startle a rabbit from his repose, and off he would scamper in great affright. But it was getting near sundown and we were miles from our wagon, and even when we reached that we would be ten miles from home, so we set out on our return with spirits not lacking, but appetites sorely pressing. The miles of climbing up hill and down hill in the pure air had done us more good than months in a gymnasium, and when, long after dark, we reached our home in Fresno town, what a supper we did eat.
