On the next day they were in the flat, nearing the post. There was a dust storm. Earlier in the morning the air had grown suddenly more dry, more close and lifeless than ever, suffocating, and a yellow cloud had come in the western sky. Then a hot wind began to blow the horses' manes and tails, to snarl through the greasewood bushes, and to snap the loose ends of the men's handkerchiefs sharply. The cloud had thinned and spread, high up in the sky, and the light had become almost that of a sullen evening. Black bits floated and whirled high overhead, and birds beat about in the gale. Gradually the gale and the dust had dropped nearer to the earth, a sand mist had gone into every pore and choked and parched. And now the tepid, thick wind was moaning across the plain, meeting no point of resistance anywhere. Landor still rode at the head of his column, but his chin was sunk down on his red silk neckerchief, his face was swollen and distorted under its thick beard, and his eyes were glazed. They stared straight ahead into the sand whirl and the sulphurous glare. He had sent Brewster on ahead some hours before. "You will want to see Miss McLane as soon as possible," he had said, "and there is no need of both of us here." Brewster had taken an escort and disappeared down the vista of white sands and scrub growth, though it was Landor himself who should have gone. He swayed now in the saddle, his thick lips hung open, and he moved in a mental cloud as dense as the one of dust that poured round him. Brewster reached the post some eighteen hours ahead of him. He reported, and saw Miss McLane; then he made himself again as other men and went down to the post trader's, with a definite aim in view, that was hardly to be guessed from his loitering walk. There were several already in the officers' room, and they talked, as a matter of course, of the campaign. "Seen the way Landor's been catching it?" they asked. And Brewster said he had not. They went on to tell him that it was all in the Tucson papers, which Brewster knew, however, quite as well as they did themselves. He had made friends among the citizen volunteers of San Tomaso on the night they had camped by the old lake bed, and they had seen that he was kept supplied with cuttings. But he pleaded entire ignorance, and the others were at considerable pains to enlighten him. It appeared that Landor was accused of cowardice, and that his name was handled with the delicate sarcasm usual with Western journalism--as fine and pointed as a Stone-age axe. Brewster poured himself a glass of beer and drank it contemplatively and was silent. Then he set it down on the bare table with a sharp little rap, suggesting determination made. It was suggestive of yet more than this, and caused them to say "Well?" with a certain eagerness. He shrugged his shoulders and changed the subject, refusing pointedly to be brought back to it, and succeeding altogether in the aim which had brought him down there.
