Mrs. Thorne had coughed as Garda ended her speech. Mrs. Thorne often coughed, and her coughs had a character of their own; they did not appear to be pulmonary. They were delicate little sounds which came forth apologetically, shielded by her hand, never quite completed; they were not coughs so much as suggestions of coughs, and with these suggestions she was in the habit of filling little pauses in the conversation, covering up the awkwardnesses or mistakes of others (there were never any of her own to cover), or acting as hyphen for disjointed remarks when people had forgotten what they were going to say. It was, indeed, a most accomplished cough, all Gracias had been indebted to it. Lately, too, she had begun to use it to veil her own little periods of consultation with herself regarding her daughter; for she seemed by no means certain of the direction which this daughter's thoughts or words might take, and the uncertainty troubled her careful maternal mind. Garda, however, though often out of sight round some unexpected corner, was never far distant; the hurrying elderly comprehension always caught up with her before long; but these periods of uncertainty, combined with cares more material, had ended by impressing upon Mrs. Thorne's face the look of anxiety which was now its most constant expression--an anxiety covered, however, as much as possible, by the mask of minutely careful politeness which fitted closely over it, doing its best to conceal, or, failing in that, to at least mark as private, the personal troubles which lay underneath. "Mamma's cough means that I am not sufficiently polite," said Garda; "I always know what mamma's cough means." She rose, passed behind her mother's chair, and bending forward over her small head, lightly kissed her forehead. "I will go, mamma," she said, caressingly. "I will be beautifully good, because to-morrow is your birthday; it ought to be a dear little day, about six hours long, to fit you." "I am fortunate to have asked my favor upon the eve of an anniversary," said Winthrop. "You are," answered Garda, taking her broad-brimmed hat from the nail behind her. "It's only upon such great occasions that I am really and angelically good--as mamma would like me to be all the time." "I will send Raquel after you, my daughter, with the umbrellas," said Mrs. Thorne, with a little movement of her lips and throat, as though she had just swallowed something of a pleasant taste, which was, with her, the expression of content. "Surely it is not going to rain?" said Winthrop, examining the sky. "They are sun-umbrellas; you may need them," answered his hostess, with a certain increased primness of accentuation, which immediately brought to his mind the idea that the carrier of these articles would represent the duenna whom she considered necessary. "A Spanish graft, that, on the original New England tree," was his mental comment. "I wonder how many more there are?"
