There was no hat on Dad’s head, because he believed that wind and sunshine kept your hair from falling out; so the boy also rode with tumbled locks. The only difference between them, apart from size, was that Dad had a big brown cigar, unlighted, in the corner of his mouth; a survival of the rough old days, when he had driven mule-teams and chewed tobacco.
Fifty miles, said the speedometer; that was Dad’s rule for open country, and he never varied it, except in wet weather. Grades made no difference; the fraction of an ounce more pressure with his right foot, and the car raced on—up, up, up—until it topped the ridge, and was sailing down into the next little valley, exactly in the centre of the magic grey ribbon of concrete. The car would start to gather speed on the down grade, and Dad would lift the pressure of his foot a trifle, and let the resistance of the engine check the speed. Fifty miles was enough, said Dad; he was a man of order.
Far ahead, over the tops of several waves of ground, another car was coming. A small black speck, it went down out of sight, and came up bigger; the next time it was bigger yet; the next time—it was on the slope above you, rushing at you, faster and faster, a mighty projectile hurled out of a six-foot cannon. Now came a moment to test the nerve of a motorist. The magic ribbon of concrete had no stretching powers. The ground at the sides had been prepared for emergencies, but you could not always be sure how well it had been prepared, and if you went off at fifty miles an hour you would get disagreeable waverings of the wheels; you might find the neatly trimmed concrete raised several inches above the earth at the side of it, forcing you to run along on the earth until you could find a place to swing in again; there might be soft sand, which would swerve you this way and that, or wet clay which would skid you, and put a sudden end to your journey.
So the laws of good driving forbade you to go off the magic ribbon except in extreme emergencies. You were ethically entitled to several inches of margin at the right-hand edge: and the man approaching you was entitled to an equal number of inches; which left a remainder of inches between the two projectiles as they shot by. It sounds risky as one tells it, but the heavens are run on the basis of similar calculations, and while collisions do happen, they leave time enough in between for universes to be formed, and successful careers conducted by men of affairs.
