Lonesome Dove, Volume 1 by Larry McMurtry

AUGUSTUS RODE BACK to camp a little after sunset, thinking the work would have stopped by then. The cattle were being held in a long valley near the river, some five miles from town. Every night Call went across the river with five or six hands and came back with two or three hundred Mexican cattle-longhorns mostly, skinny as rails and wild as deer. Whatever they got they branded the next day, with the part of the crew that had rested doing the hard end of the work. Only Call worked both shifts. If he slept, it was an hour or two before breakfast or after supper. The rest of the time he worked, and so far as anyone could tell the pace agreed with him. He had taken to riding the Hell Bitch two days out of three, and the mare seemed no more affected by the work than he was.

Bolivar had not taken kindly to being moved to a straggly camp out in the brush, with no dinner bell to whack or crowbar to whack it with. He kept his ten-gauge near the chuck box and scowled at everybody. The Irishmen were so intimidated that they were always the last ones in line. As a consequence they got little to eat and were no longer as fat as they had been the day they arrived.
