Then, when "Billy" Brackett came over, and went on beyond Glen, he set the level up so high on the bank that, through it, he could just see the top of the rod, extended to its extreme length. So they climbed slowly up out of the Colorado Valley, and began to traverse the dreary country that lay between it and the Sierra Nevada.
