Once or twice Fulvia showed herself for a moment; but her manner was retiring and almost constrained, and her father always contrived an excuse for dismissing her. This was the more noticeable as she continued to appear at the meetings of the Honey-Bees, where she joined freely in the conversation, and sometimes diverted the guests by playing on the harpsichord or by recitations from the poets; all with such art and grace, and withal so much simplicity, that it was clear she was accustomed to the part. Odo was thus driven to the not unflattering conclusion that she had been instructed to avoid his company; and after the first disappointment he was too honest to regret it. He was deeply drawn to the girl; but what part could she play in the life of a man of his rank? The cadet of an impoverished house, it was unlikely that he would marry; and should he do so, custom forbade even the thought of taking a wife outside of his class. Had he been admitted to free intercourse with Fulvia, love might have routed such prudent counsels; but in the society of her father's associates, where she moved, as in a halo of learning, amid the respectful admiration of middle-aged philosophers and jurists, she seemed as inaccessible as a young Minerva. Odo, at first, had been careful not to visit Vivaldi too often; but the Professor's conversation was so instructive, and his library so inviting, that inclination got the better of prudence, and the young man fell into the habit of turning almost daily down the lane behind the Corpus Domini. Vivaldi, too proud to betray any concern for his personal safety, showed no sign of resenting the frequency of these visits; indeed, he received Odo with an increasing cordiality that, to an older observer, might have betokened an effort to hide his apprehension.
