What the tall man said he could not hear. He spoke low--seemed to be arguing with the old man, begging him to be quiet, and they went into the office. Then the young man walked on a few hundred yards, when it came on to rain very hard, and he stopped and took shelter under a little fishing-shed there was right at the edge of the lake. The rain held up in fifteen minutes, and he started on again over the causeway, "and hadn't more'n got a rod" when he heard what sounded like a pistol-shot back at the mill. He stopped short and listened two minutes, but heard nothing more, so went on and thought no more of it until he heard of the murder--but that was not until a week after it happened, when he came up from the farm to Eagle village and heard people talking about it. But with the first week in August came exciting news. Far to the northwest across the Missouri, Dick Graham had been traced and followed by a Wisconsin detective, who found him in the uniform of the regular army, just marching off with his comrades to join General Terry's forces, then in the field up the Yellowstone. In his possession was the Avenger revolver and over one hundred dollars in greenbacks. On two five-dollar bills there was a broad and ugly stain, which microscopic examination proved to be blood. Graham appeared utterly stunned at the arrest; expressed the greatest grief and horror at hearing of the murder of Mr. Morrow, and professed his entire willingness to go back and stand trial. The story of his "escape" to that distance was now easily told. The detectives had speedily satisfied themselves he had got away on none of the regular trains that week, but one bright fellow had learned that four cars full of troops had passed west late that Sunday night, and followed the clue. They had gone through to Bismarck--a tedious journey in '76--and thither he followed. Thence the troops had gone by boat up the Missouri, and he took the first opportunity that came--and the next boat going up. At Fort Buford he "sighted" his man, told his story to the commanding officer of the post, who sent for the officers of the troops with whom poor Dick was serving. They promptly asserted that their first knowledge of him was on the Monday they reached St. Paul, when a sergeant brought him to them, saying he begged to be allowed to enlist and go with them. He told a perfectly straight story; said he was an orphan, unmarried, had been a miller, but was tired of small wages, hard work, and no hopes of getting ahead, and had made up his mind to get into the regulars. Was at the railway station at midnight when the train was side-tracked to allow another to pass, and appealed to the sergeant of the guard to take him along; said he would pay his way until they could enlist him, and as he was a likely fellow they were glad to have him. He had won everybody's respect in the short time he was with them, and the whole command seemed thunderstruck to hear of the allegations against him.
