"Mr. Morrow," said he, "I believe I met and knew your son on the Pacific coast. What is more, I believe I can find him." The miller knew that Frost's relations were people of high position, but did not know that the man before him was very far from standing well in their esteem. But he had been imposed upon more than once by people who sought to make money from his eagerness to obtain any clue to the whereabouts of his missing boy. He closely questioned Frost, and was speedily convinced that there was no imposition here. He had known him, and known him well; for, even in little tricks of speech and manner, Frost could describe Sam to the life. The old man's first impulse was to take Frost with him and start for the Pacific coast at once; but the latter pointed out to him that the journey to mid Arizona was very long and expensive, and that he had reason to believe Sam had left there and gone with miners to Montana. He had friends and correspondents; he would write; he did write, and showed Morrow the letters, and they went apparently to Prescott, Arizona, but not for three months did answers come; and then they were vague and indefinite, and meantime the old man's heart had been torn with suspense and anxiety, and he rebelled at the restriction placed upon him by Frost, that he should admit to nobody that they were on the trail of his absent son—that Frost had known him well "in the mines," as he said, though by another name. He disliked it still more that there was so much of his own life while in the distant West of which Frost gave varying accounts, and always avoided speaking; and now it was plain that he was "making up" to Nellie; it was plain that she was far from averse to the attentions of this handsome and distinguished fellow, with his air of reserve and mystery; and it was plain that poor Dick Graham was both miserable and suspicious. He had been set against Frost from the very first.

Still there was a certain element with whom he had attained popularity—the young men about the village, and especially those of the large and thriving town over on the railway. He was a superb horseman, and had ridden with grace and ease a horse that poor Dick had pronounced utterly unmanageable. Then, one night during the Easter holidays, a large party of the young people of Nemahbin had driven over to town to attend the ball given by a local military organization. Nellie was the belle on the occasion, and was coquetting promiscuously with the officers and the members of the company, evidently to the annoyance of that hitherto unrivalled Mr. Frost. Even gloomy Dick Graham found some comfort in this, but his comfort gave way to dismay when, after a brief and rather clumsily executed drill of his command, the captain had suddenly turned over his sword to Mr. Frost, and the latter, as though by previous arrangement, stepped forward, and, with all the ease of an expert tactician and drill-master, and with stirring, martial voice and bearing, put the company through one evolution after another with surprising rapidity, and finally retired, the applauded and envied hero of the occasion. Nellie had monopolized him the rest of the evening, and all men held him in great esteem. Questioned as to his wonderful proficiency, he laughingly answered, "Why, I soldiered through the last two years of the war in the volunteers, and saw a good deal of the regulars afterwards, out West—that is, I used to watch them with great interest," and quickly changed the subject.

But Dick Graham's jealous eyes—and no eyes are so sharp as those whose scrutiny is so whetted—marked that he had changed color, and that his manner was nervous and embarrassed. From that day on he watched Frost like a cat.

June came in with sunshine and roses, and a great centennial celebration and exhibition in the far East, and a great convention for the nomination of a president, and the country was so taken up with these stirring events that, when June went out, precious little attention was paid to an affair that, a year earlier or later, would have thrilled the continent with horror. In one short, sharp, desperate struggle of a quarter of an hour, Custer, the daring cavalry leader of the great war—Custer, the yellow-haired, the brave, the dashing, the hero of romance and fiction and soldierly story—Custer and his whole command had been swept out of existence by an overwhelming force of Indians.

Nellie was home again, and Frost was now occupying a room in Sam Morrow's little house. The old man had come to Dick but a short time before her return, and, with something of his old kind and confidential way, had said to him that Frost was to remain with them but a few weeks longer, and that he was unwilling to have him under the same roof with Nellie even during that little while. Morrow had begun to look on Frost as a liar. He felt certain that he had known his lost boy, but doubted now his pretensions as to his ability to find him. Indeed, Frost admitted that he had lost the clue, and it was at this time that Morrow at last told the minister of the matter. That he was being deceived in more ways than one the old man was convinced, yet had nothing tangible to work upon; but his worst suspicions had not really done justice to the facts in the case. Morrow would have killed the man could he have known the truth—that he knew well just where the missing son was to be found, and would not tell—and that, virtually robbing the old miller of one child, he had now well-nigh robbed him of the other. Between him and Nellie letters had secretly passed, at regular intervals, ever since the Christmas vacation. She was fascinated, yet she, too, distrusted. He swore that he loved her—longed to make her his wife—yet forbade her confessing to her father that such was the case. More than that, he had cautioned her to look for an indifferent manner on his part on her return. He explained that her father disliked him, and would send him away instantly if their love were suspected. He even urged her to encourage Dick Graham. He was playing a desperate game, indeed. He had hoped to win the father's confidence with the daughter's love, and secure his consent—and blessing—and fortune; but, as matters stood, he knew that, though he might win Nellie, it would be in defiance of the father's will, and that meant disinheritance and banishment for both.

By every art in his power he had striven, of late, to curry favor with Graham, but without success. Dick was coldly civil, and would have been thankful for an excuse at open rupture. He suspected Frost of having won Nellie away from him, but could prove absolutely nothing. He believed him to be a mere adventurer, and had urged the miller to write to those connections of whom he had boasted—the Chicago relatives—and ascertain his history; but Morrow had sternly silenced him with the information that he knew it all—at least he knew enough. "Mr. Frost is here for a purpose, and it is sufficient that I have brought him here," was the old man's reply to further objections, and so poor Dick felt that nothing more was to be said.

But with Nellie's return came a revival of hope. She was sweeter, prettier than ever, and her manner to Dick was now as gentle, and even confidential, as it had been careless and indifferent during the late winter. She came home about the 15th of June, and for the fortnight that followed it was Dick, not Mr. Frost, whom she seemed to favor. Graham hardly dared believe the evidence of his senses, but was too blissful to analyze matters. The old man, of late, had taken to spending some hours in the evening down at his office in the mill, and Frost was generally closeted there with him. Very surly and sad and irascible the miller had grown. He was bitter and unjust to everybody. Several times he had angrily reprimanded Graham in the presence of customers and mill-hands for things that were entirely of Frost's doing. There had been errors in the accounts, over which the farmers had growled not a little; and one day, bursting from a group of men who had been calling his attention to a matter of the kind, the old man stamped furiously into the office, shut the door after him with a bang, and was heard to say, in loud and angry tones, to some one, "Now the next time this happens, by God, you go!"

A moment after, Dick Graham came from the office into the mill, and that night it was told in Nemahbin that the old man had threatened to discharge him. He and Graham seemed to get along very badly, and no man could explain it.

But, gaining hope from Nellie's smiles, Dick was ready to bear up against the old man's fit of rage. At heart, he knew the miller liked and trusted him. There was much he could not fathom, but was content to wait and watch. Meantime he kept his eye on Frost—noted how nervous and ill at ease he was becoming, marked his labored attempts to win his friendship, and withheld it the more guardedly.

One day, about a week after Nellie's return, business required that he and Frost should go together to the neighboring town on the railway. They were standing by the elevator on a side-track with a knot of young men, when a train came rumbling in from the East, and as it drew up at the station it was seen that the rear car was filled with soldiers.
