Here they were also unsuccessful; the servant who came to the door telling them that the ladies were particularly engaged and could see no company. So they left their second letter and card and drove off, continuing their ride till they reached the Croton water works, which they quitted the carriage to see and admire. On returning to the hotel, with the intention after an hour or two of rest to go out again, and walk till near dinner-time, they found waiting them a note from Mrs. Watkinson, expressing her regret that she had not been able to see them when they called; and explaining that her family duties always obliged her to deny herself the pleasure of receiving morning visitors, and that her servants had general orders to that effect. But she requested their company for that evening (naming nine o'clock as the hour), and particularly desired an immediate answer.
