"Well, what, then, was the cause?" After eliminating Marjory from the discussion waging in his mind, he found it hard to hit upon anything rational. The only remaining theory was to the effect that the professor, having a very high sense of the correspond. ent's help in the escape of the Wainwright party, had decided that the only way to express his gratitude was to revoke a certain decision which he now could see had been unfair. The retort to this theory seemed to be that if the professor had had such a fine conception of the services rendered by Coleman, he had had ample time to display his appreciation on the road to Arta and on the road down from Arta. There was no necessity for his waiting until their arrival in Athens. It was impossible to concede that the professor's emotion could be anew one; if he had it now, he must have had it in far stronger measure directly after he had been hauled out of danger. So, it may be seen that after Coleman had eliminated Marjory from the discussion that was waging in his mind, he had practically succeeded in eliminating the professor as well. This, he thought, mournfully, was eliminating with a vengeance. If he dissolved all the factors he could hardly proceed. The mind of a lover moves in a circle, or at least on a more circular course than other minds, some of which at times even seem to move almost in a straight line. Presently, Coleman was at the point where he bad started, and he did not pause until he reached that theory which asserted that the professor had been inspired to his visit by some sight or knowledge of Marjory in distress. Of course, Coleman was wistfully desirous of proving to himself the truth of this theory. The palpable agitation of the professor during the interview seemed to support it. If he had come on a mere journey of conscience, he would have hardly appeared as a white and trembling old, man. But then, said Coleman, he himself probably exaggerated this idea of the professor's appearance. It might have been that he was only sour and distressed over the performance of a very disagreeable duty. The correspondent paced his room and smoked. Sometimes he halted at the little table where was the brandy and soda. He thought so hard that sometimes it seemed that Marjory had been to him to propose marriage, and at other times it seemed that there had been no visit from any one at all.
