Miss Terrell, in her utter inability to adjust the American coinage to English standards, and also in the kindness of her heart, had given too generous tips to all of the hotel waiters, and some of this money had passed into the gallery window of the Broadway Theatre, where the hotel waiters had heard her sing and seen her dance, and had failed to recognize her young husband in the Lord Chancellor's wig and black silk court dress.
