We congratulated ourselves that we should at least have a night of delightful sleep on the steamboat in the quiet of this secluded harbor. But it was wisely ordered otherwise, to the end that we should improve our time by an interesting study of human nature. Towards midnight, when the occupants of all the state-rooms were supposed to be in profound slumber, there was an invasion of the small cabin by a large and loquacious family, who had been making an excursion on the island railway. This family might remind an antiquated novel-reader of the delightful Brangtons in "Evelina;" they had all the vivacity of the pleasant cousins of the heroine of that story, and the same generosity towards the public in regard to their family affairs. Before they had been in the cabin an hour, we felt as if we knew every one of them. There was a great squabble as to where and how they should sleep; and when this was over, the revelations of the nature of their beds and their peculiar habits of sleep continued to pierce the thin deal partitions of the adjoining state-rooms. When all the possible trivialities of vacant minds seemed to have been exhausted, there followed a half-hour of "Goodnight, pa; good-night, ma;" "Goodnight, pet;" and "Are you asleep, ma?" "No." "Are you asleep, pa?" "No; go to sleep, pet." "I'm going. Good-night, pa; good-night, ma." "Goodnight, pet." "This bed is too short." "Why don't you take the other?" "I'm all fixed now." "Well, go to sleep; good-night." "Good-night, ma; goodnight, pa,"--no answer. "Good-night,pa." "Goodnight, pet." "Ma, are you asleep?" "Most." "This bed is all lumps; I wish I'd gone downstairs." "Well, pa will get up." "Pa, are you asleep?" "Yes." "It's better now; good-night, pa." "Goodnight, pet." "Good-night, ma." "Good-night, pet." And so on in an exasperating repetition, until every passenger on the boat must have been thoroughly informed of the manner in which this interesting family habitually settled itself to repose.
