As the summer wore on, the number of those pathetically eager for letters increased. The sun-bright plain, the beautiful, almost cloudless sky, and the ever-flooding light wore upon them. They began to recall wistfully the cool streams of New England, the wooded slopes of Wisconsin, the comfortable homesteads and meadows of Illinois, and they came for their mail with shining eyes--and when forced to say "Nothing to-day," Bailey always suffered a keen pang of sympathetic pain. He himself watched the eastern horizon, incessantly and unconsciously, hours before the wagon was due, and, when it came in sight at last, ran his flag up along its mast joyously. It was a great pleasure to him to sit and talk with his partner, and he looked forward to his visits eagerly. To Jim he could utter himself freely. They had known each other so long, and he believed he understood his partner to the centre of his heart. He usually had supper ready--often he had help from the girls or Mrs. Burke, and while a dozen hands volunteered at the team and with the mail-bag, Rivers was free to hurry to his table, whereat he fared like a pasha attended by the flower of his harem. The girls pretended it was all on account of his office as mail-carrier, but they deceived no one, much less an experienced beau like Rivers. He accepted it all with shameless egotism. To Bailey's mind Jim was too well attended. He seemed to see less and less of his partner as the season wore on. They seldom sat down to talk in the good old fashion, wearing out half the night smoking, listening to the slumber-song of the night plain, for Rivers got into the habit of walking home with some of the girls after the mail was distributed, leaving his partner to do the trading. Sometimes he went away with Mrs. Burke, if she were alone; sometimes with Estelle Clayton, whom Bailey thought the finest woman in the world. He secretly resented Rivers' attention to Estelle, for he had come to look upon her as under his protection. Her coming raised mail-days to the level of a national holiday. She scared him, and yet he rejoiced to see her coming down over the sod so strong, so erect, so clear-eyed. She wore her hair like a matron, and that pleased him, and she looked at him so frankly and unwaveringly. She had been a school-teacher in some middle Western State, and had been swept into this movement by her desire to go to an Eastern college. Bailey contrived to look very stern and very busy whenever she came in, but she was wise in ways of men, and treated him as if he were a good comrade, and so gradually he came to talk to her almost as freely as with Blanche Burke.
