One afternoon in late October four lean mules, with stringy muscles dragging over their bones, stretched long legs at the whirring of their master's whip. The canalman was a short, ill-favored brute, with coarse red hair and freckled skin. His nose, thickened by drink, threatened the short upper lip with obliteration. Straight from ear to ear, deep under his chin, was a zigzag scar made by a razor in his boyhood days, and under emotion the injured throat became convulsed at times, causing his words to be unintelligible. The red flannel shirt, patched with colors of lighter shades, lay open to the shoulders, showing the dark, rough skin.
