They lived on the verge of a vast stony level, upheaved so far above the surrounding country that its vague outlines, viewed from the nearest valley, seemed a mere cloud-streak resting upon the lesser hills. The rush and roar of the turbulent river that washed its eastern base were lost at that height; the winds that strove with the giant pines that half way climbed its flanks spent their fury below the summit; for, at variance with most meteorological speculation, an eternal calm seemed to invest this serene altitude. The few Alpine flowers seldom thrilled their petals to a passing breeze; rain and snow fell alike perpendicularly, heavily, and monotonously over the granite bowlders scattered along its brown expanse. Although by actual measurement an inconsiderable elevation of the Sierran range, and a mere shoulder of the nearest white-faced peak that glimmered in the west, it seemed to lie so near the quiet, passionless stars, that at night it caught something of their calm remoteness. The articulate utterance of such a locality should have been a whisper; a laugh or exclamation was discordant; and the ordinary tones of the human voice on the night of the 15th of May, 1868, had a grotesque incongruity.
