Their very last excursion of all, and one of the pleasantest, was to the old amphitheatre at Fiesole; and it was while they sat there in the soft glow of the late afternoon, tying into bunches the violets which they had gathered from under walls whose foundations antedate Rome itself, that a cheery call sounded from above, and an unexpected surprise descended upon them in the shape of Lieutenant Worthington, who having secured another fifteen days' furlough, had come to take his sister on to Venice.
"I did n't write you that I had applied for leave," he explained, "because there seemed so little chance of my getting off again so soon; but as luck had it, Carruthers, whose turn it was, sprained his ankle and was laid up, and the Commodore let us exchange. I made all the capital I could out of Amy's fever; but upon my word, I felt like a humbug when I came upon her and Mrs. Swift in the Cascine just now, as I was hunting for you. How she has picked up! I should never have known her for the same child."
