During the day there had been other women in the car, travelling for shorter or longer distances. To one of these, a lady-like girl who occupied an adjoining seat for some hours, and who was greatly interested in the baby, the young mother had confided the fact that this was his birthday, and also part of her own history. From this it appeared that she was the wife of an army officer, who was stationed with his regiment in the far West. She had not seen him for nearly a year, or just after the baby was born; but at last he had been ordered to a fort on the upper Mississippi River, where he hoped to remain for some time. Now his young wife, who had only been waiting until he could give her any sort of a home with him, had bravely set forth with her baby to join him. He had written her that, on a certain date in the spring, a detachment of troops was to start from St. Louis by steamboat for the fort at which he was stationed. As one of the officers of this detachment was to take his wife with him, he thought it would be a fine opportunity for her to come at the same time. She wrote back that she could not possibly get ready by the date named, but would come by a later boat. After she had sent the letter, she found that she could get ready; and, as the aunt with whom she was living was about to break up her home and go abroad, she decided to start at once for St. Louis. There she would join her husband's friends, travel with them to the far-away fort, and give the lonely soldier a joyful surprise. There was no time to send another letter telling him of her change of plan, and she was glad of it, for a surprise would be so much nicer.
