Oil! by Upton Sinclair

But something went wrong and spoiled the schedule. You had got up into the fog, and cold white veils were sweeping your face. You could see all right, but the fog had wet the road, and there was clay on it, a combination that left the most skilful driver helpless. Dad's quick eye noted it, and he slowed down; a fortunate thing, for the car began to slide, and almost touched the white wooden barrier that guarded the outer edge.

They started again, creeping along, in low gear, so that they could stop quickly; five miles the speedometer showed, then three miles; then another slide, and Dad said "Damn. " They wouldn't stand that very long, the boy knew; "Chains," he thought, and they drew up close against the side of the hill, on an inside curve where cars coming from either direction could see them. The boy opened the door at his side and popped out; the father descended gravely, and took off his overcoat and laid it in the seat; he took off his coat and laid that in the same way -- for clothing was part of a man's dignity, a symbol of his rise in life, and never to be soiled or crumpled. He unfastened his cuffs and rolled up the sleeves -- each motion precisely followed by the boy. At the rear of the car was a flat compartment with a sloping cover, which Dad opened with a key; one of a great number of keys, each precisely known to him, each symbolical of efficiency and order. Having got out the chains, and fastened them upon the rear tires, Dad wiped his hands on the fog-laden plants by the roadside; the boy did the same, liking the coldness of the shining globes of water. There was a clean rag in the compartment, kept there for drying your hands, and changed every so often. The two donned their coats again, and resumed their places, and the car set out, a little faster now, but still cautiously, and away off the schedule.
