CHAPTER XXI.
The engagement of the Senorita Rosita Campaneo was for four weeks, during which Mr.King called frequently and attended the opera constantly.

Every personal interview, and every vision of her on the stage, deepened the impression she made upon him when they first met.
It gratified him to see that, among the shower of bouquets she was constantly receiving, his was the one she usually carried; nor was she unobservant that he always wore a fresh rose.

But she was unconscious of his continual guardianship, and he was careful that she should remain so.

Every night that she went to the opera and returned from it, he assumed a dress like the driver's, and sat with him on the outside of the carriage,--a fact known only to Madame and the Signor, who were glad enough to have a friend at hand in case Mr.Fitzgerald should attempt any rash enterprise.

Policemen were secretly employed to keep the _cantatrice_ in sight, whenever she went abroad for air or recreation.
