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. "Guadalupe Grade: Height of Land: Caution: Fifteen miles per hour on curves." So ran the sign; they were creeping down now, in low gear, holding back the car, which resented it, and shook impatiently. Dad had his spectacles in his lap, because the fog had blurred them; it had filled his hair with moisture, and was trickling down his forehead into his eyes. It was fun to breathe it and feel the cold; it was fun to reach over and sound the horn—Dad would let you do it now, all you wanted. A car came creeping towards them out of the mist, likewise tooting lustily; it was a Ford, puffing from the climb, with steam coming out of the radiator. Then suddenly the fog grew thinner; a few wisps more, and it was gone; they were free, and the car leaped forward into a view—oh, wonderful! Hill below hill dropping away, and a landscape spread out, as far as forever; you wanted wings, so as to dive down there, to sail out over the hilltops and the flat plains. What was the use of speed limits, and curves, and restraining gears and brakes?—"Dry my spectacles," said Dad, prosaically. Scenery was all right, but he had to keep to the right of the white-painted line on the road. "Whanhnh! Whanhnh!" said the horn, on all the outside curves. They slid down, and little by little the scenery disappeared; they were common mortals, back on earth. The curves broadened out, they left the last shoulder of the last hill, and before them was a long, straight descent; the wind began to whistle, and the figures to creep past the red line on the speedometer. They were making up for lost time. Wheel How the trees and telegraph poles went whizzing! Sixty miles now; some people might have been scared, but no sensible person would be scared while Dad was at the wheel. But suddenly the car began to slow up; you could feel yourself sliding forward in your seat, and the little red line showed fifty, forty, thirty. The road lay straight ahead, there was no other car in sight, yet Dad's foot was on the brake. The boy looked up inquiringly. "Sit still," said the man. "Don't look round. A speed-trap!" Oho! An adventure to make a boy's heart jump! He wanted to look and see, but understood that he must sit rigid, staring out in front, utterly innocent. They had never driven any faster than thirty miles per hour in their lives, and if any traffic officer thought he had seen them coming faster down the grade, that was purely an optical delusion, the natural error of a man whose occupation destroyed his faith in human nature. Yes, it must be a dreadful thing to be a "speed-cop," and have the whole human race for your enemy! To stoop to
