"It has been a great pleasure to me--well, these are not the right words," said the young fellow with sudden gravity and a shade of agitation in his manner. "I count it the greatest piece of good fortune which ever befell me that I took St. Ebbe's for my hospital. But I ought not to presume on my acquaintance with Miss Millar," he began again immediately, with an infusion of cautious reserve and something like vexation creeping into his tone; "it is purely professional. We are far too busy people at St. Ebbe's to know each other as private persons. Very likely if you ask her, she will deny all knowledge of me as an individual; she may not even be able to recall the fact of my existence apart from a circle of big uncouth medical students in the train of the doctors--all alike to her. At the same time I have drunk tea in her company both in the matron's room and in Dr. Moss's, and I have often sat near her in the services at the hospital chapel," he ended a little defiantly. The speech, save for its ring of half-boyish mortification, was suspicious, as if he were providing a loophole for escape in case Annie refused to indorse his assertion of mutual acquaintance. But Rose, in spite of her spirit and quickness, was hardly more given to suspicion than her sister May showed herself, and saw nothing dubious in his remark. She was carried away with the agreeable surprise of having stumbled on somebody connected with St. Ebbe's who knew all about Annie. She chatted on in the frankest, friendliest way, plying him with girlish questions, and supplying free comments on his answers; and he was an auditor who was nothing loth to be so treated, and to be furnished with stores of information on points which had aroused his ardent curiosity. She forgot all about taking him out of his way, and when they reached Welby Square she crowned her unbounded faith in him by inviting him into the house. On his acceptance of her invitation, after a moment's hesitation, she presented him to Mrs. Jennings as a friend of Annie's from St. Ebbe's. The young man had the grace to feel his ears tingle while Mrs. Jennings, looking a little astonished, took him on Rose's word, bowed her welcome, begged him to sit down with her usual gracious, languid good-breeding, and said she was glad to see any friend of Miss Annie Millar's. He did his best, with a flushed face, to remedy his and Rose's rashness. He put down his card, with Harry Ironside, M.D., engraved on it, at Mrs. Jennings's elbow. He set himself with a strenuous and sincere effort to talk to her, and so to conduct himself as to do credit to Rose's voucher. Mrs. Jennings was easily propitiated on receiving the attention which was due to her. She thought the young man's manners perfectly good; they had well-bred ease, and at the same time the modesty which ought to accompany youth, though his introduction to her had been somewhat informal.
