They came to a little house by the roadside, with a shed that you drove under, and a round-bellied object, half glass and half red paint, that meant gasoline for sale. “Free Air,” read a sign, and Dad drew up, and told the man to take off his chains. The man brought a jack and lifted the car; and the boy, who was always on the ground the instant the car stopped, opened the rear compartment and got out the little bag for the chains to go in. Also he got out the “grease-gun”, and unwrapped that. “Grease is cheaper than steel,” Dad would say. He had many such maxims, a whole modern Book of Proverbs which the boy learned by heart. It was not that Dad was anxious to save the money; nor was it that he had grease to sell and not steel; it was the general principle of doing things right, of paying respect to a beautiful piece of machinery. Dad had got out, to stretch his legs. He was a big figure of a man, filling every inch of the opulent overcoat. His cheeks were rosy, and always fresh from the razor; but at second glance you noted little pockets of flesh about his eyes, and a network of wrinkles. His hair was grey; he had had many cares, and was getting old. His features were big and his whole face round, but he had a solid jaw, which he could set in ugly determination. For the most part, however, his expression was placid, rather bovine, and his thoughts came slowly and stayed a long time. On occasions such as the present he would show a genial side—he liked to talk with the plain sort of folks he met along the road, folks of his own sort, who did not notice his extremely crude English; folks who weren’t trying to get any money out of him—at least not enough to matter. He was pleased to tell this man at the “filling station” about the weather up there in the pass; yes, the fog was thick—delayed them quite a bit—bad place for skidding. Lots of cars got into trouble up there, said the man—that soil was dobe, slick as glass; have to trench the road better. Quite a job that, Dad thought—taking off the side of the mountain. The man said the fog was going now—lots of “high fog” in the month of May, but generally it cleared up by noon. The man wanted to know if Dad needed any gas, and Dad said no, they had got a supply before they tackled the grade. The truth was, Dad was particular, he didn’t like to use any gas but his own make; but he wouldn’t say that to the man, because it might hurt the man’s feelings.
