ken the
night-key from the former, and put it in his vest pocket; and when he
reached the front door of the mansion, the key he wanted was in his
chamber, and he had been careful to shut the door when he left the
house.

He could not get in, and he walked around the building to find a window
which had not been closed. His mother had a reasonable dread of robbers,
and she always looked out for the windows before she retired. He did
not wish to arouse the family by ringing the great gong bell, but it was
too cold to spend the rest of the night out-doors in his half-clothed

the matter, ma'am," and still he gazed at the young gentleman, as though
he deemed it possible that he had suddenly gone crazy.

"Nothing is the matter, mother," called Christy. "I am all right."

"But why are you out at this time of night, my son? It is nearly two
o'clock in the morning," said Mrs. Passford, as she descended the
stairs. "You are not half dressed, Christy."

"But I am all right, mother, and there is not the least reason to worry
about anything, for the ship is not going to the bottom just yet,"
replied Christy, indulging in a forced laugh to assist in quieting his
mother's fears.
