On the morning after their arrival at the great commercial metropolis of America, the Morland family took a carriage to ride round through the principal parts of the city, and to deliver their two letters at the houses to which they were addressed, and which were both situated in the region that lies between the upper part of Broadway and the North River. In one of the most fashionable streets they found the elegant mansion of Mrs. St. Leonard; but on stopping at the door, were informed that its mistress was not at home. They then left the introductory letter (which they had prepared for this mischance, by enclosing it in an envelope with a card), and proceeding to another street considerably farther up, they arrived at the dwelling of the Watkinson family, to the mistress of which the other Philadelphia letter was directed. It was one of a large block of houses all exactly alike, and all shut up from top to bottom, according to a custom more prevalent in New York than in any other city.
