a matter of public concern

"The train was approaching it at an angle, and the apex was Yellow Sky. Presently it was apparent that, as the distance from Yellow Sky grew shorter, the husband became commensurately restless. His brick-red hands were more insistent in their prominence. Occasionally he was even rather absent-minded and far-away when the bride leaned forward and addressed him.
     As a matter of truth, Jack Potter was beginning to find the shadow of a deed weigh upon him like a leaden slab. He, the town marshal of Yellow Sky, a man known, liked, and feared in his corner, a prominent person, had gone to San Antonio to meet a girl he believed he loved, and there, after the usual prayers, had actually induced her to marry him, without consulting Yellow Sky for any part of the transaction. He was now bringing his bride before an innocent and unsuspecting community.
     Of course, people in Yellow Sky married as it pleased them, in accordance with a general custom; but such was Potter's thought of his duty to his friends, or of their idea of his duty, or of an unspoken form which does not control men in these matters, that he felt he was heinous. He had committed an extraordinary crime. Face to face with this girl in San Antonio, and spurred by his sharp impulse, he had gone headlong over all the social hedges. At San Antonio he was like a man hidden in the dark. A knife to sever any friendly duty, any form, was easy to his hand in that remote city. But the hour of Yellow Sky, the hour of daylight, was approaching."
