being a rusty country doctor and old fogy who had not kept up with the times; but many a letter followed him home, with thanks for some helpful suggestion or advice as to the management of a troublesome case. He was too far away to give room for any danger of professional jealousy, or for the infringement of that ever lengthening code of etiquette so important to the sensitive medical mind. Therefore he had only much pleasure and a fine tribute of recognition and honor, and he smiled more than once as he sat in the quiet Oldfields study before the fire, and looked up at Captain Finch's little ship, and told Nan of his town experiences, not always omitting, though attempting to deprecate, the compliments, in some half-hour when they were on peculiarly good terms with each other. And Nan believed there could be no better doctor in the world, and stoutly told him so, and yet listened only half-convinced when he said that he had a great mind to go to town and open an office, and make a specialty of treating diseases of the heart, since everybody had a specialty nowadays. He never felt so ready for practice as now, but Nan somehow could not bear the thought of his being anywhere but in his home. For herself, she would have been ready to venture anything if it would further her ever-growing purpose; but that Dr. Leslie should begin a new career or contest with the world seemed impossible. He was not so strong as he used to be, and he was already famous among his fellows. She would help him with his work by and by even more than now, and her own chosen calling of a country doctor was the dearer to her, because he had followed it so gallantly before her loving and admiring eyes. But Dr. Leslie built many a castle in the air, with himself and a great city practice for tenants, and said that it would be a capital thing for Nan; she could go on with it alone by and by. It was astonishing how little some of the city doctors knew: they relied upon each other too much; they should all be forced to drive over hill and dale, and be knocked about in a hard country practice for eight or ten years before they went to town. "Plenty of time to read their books in June and January," the doctor would grumble to himself, and turn to look fondly at the long rows of his dear library acquaintances, his Braithwaites and Lancets, and their younger brothers, beside the first new Sydenham Society's books, with their clumsy blot of gilding. And he would stand sometimes with his hands behind him and look at the many familiar rows of brown leather-covered volumes, most of them delightfully worn with his own use and that of the other physicians whose generous friend and constant instructor he had been through years of sometimes stormy but usually friendly intercourse and association.
