"Well?" queried she, seeing that something troubled him too much to be evaded. "But who am I?" he demanded, so earnestly that the absurdity of such a question was lost in its pathos. "Who are you?" she echoed, in bewilderment. Then, with the instant reflection that he was still too near delirium and brain-fever to be allowed to trouble himself with speculations, she added, brightly, and with the air of one who settles all possible doubts, "Why, you are yourself, of course." She smiled so dazzlingly as she spoke that a complete faith in her assurances mingled itself with some dimly felt sense of the ludicrous in the sick man's mind, and although the baffled look did not at once disappear from his face, yet he said nothing further, and not long after he fell asleep, leaving Columbine free to seek her arbor again and ponder on this new phase of her interesting case. She attached no serious importance then to the fact that her patient seemed so uncertain concerning his identity; but, as the days went by, and he was as completely unable to answer his own query as ever, a strange, baffled feeling stole over her; a teasing sense of being brought helplessly face to face with a mystery to which she had no key. His convalescence was somewhat slow, the hurts he had received having been of a very serious nature; but when he was able to leave his room, and even to accompany Columbine to her favorite arbor, he was still grappling vainly with the problem of who and what he was. This first visit to the arbor, it should be noted, was an event in the quiet life at the old house. Columbine was full of petty excitement over it, her fair cheeks flushed and her hair disordered with running to and fro to see that the cushions were in place, the sun shining at the right angle, and the breeze not too fresh. She insisted upon supporting the sick man on one side, while faithful old Sarah, her nurse in childhood, and since promoted to fill at once the place of housekeeper and all the departed servants, took his arm upon the other to help him along the smoothly trodden path through the neglected garden. Mr. Dysart was as usual in his library, and to disturb him there was a venture requiring more daring than either of the women possessed. They got on very tolerably without him, however, and the patient was soon installed amid a pile of wraps and shawls in the summer-house, where he was left in charge of Miss Dysart, while Sarah returned to her household avocations.
