At last the train, steaming down the valley of the Arno, revealed fair Florence sitting among olive-clad hills, with Giotto's beautiful Bell-tower, and the great, many-colored, soft-hued Cathedral, and the square tower of the old Palace, and the quaint bridges over the river, looking exactly as they do in the photographs; and Katy would have felt delighted, in spite of dust and fatigue, had not Amy looked so worn out and exhausted. They were seriously troubled about her, and for the moment could think of nothing else. Happily the fatigue did no permanent harm, and a day or two of rest made her all right again. By good fortune, a nice little apartment in the modern quarter of the city had been vacated by its winter occupants the very day of their arrival, and Mrs. Ashe secured it for a month, with all its conveniences and advantages, including a maid named Maria, who had been servant to the just departed tenants. Maria was a very tall woman, at least six feet two, and had a splendid contralto voice, which she occasionally exercised while busy over her pots and pans. It was so remarkable to hear these grand arias and recitatives proceeding from a kitchen some eight feet square, that Katy was at great pains to satisfy her curiosity about it. By aid of the dictionary and much persistent questioning, she made out that Maria in her youth had received a partial training for the opera; but in the end it was decided that she was too big and heavy for the stage, and the poor "giantess," as Amy named her, had been forced to abandon her career, and gradually had sunk to the position of a maid-of-all-work. Katy suspected that heaviness of mind as well as of body must have stood in her way; for Maria, though a good-natured giantess, was by no means quick of intelligence. "I do think that the manner in which people over here can make homes for themselves at five minutes' notice is perfectly delightful," cried Katy, at the end of their first day's housekeeping. "I wish we could do the same in America. How cosy it looks here already!"
