rather than by opening it, or he would have been
likely to find the intruder in his room when he lighted his lamp.

It seemed to him to be a matter of course that the midnight visitor had
come into the mansion for the purpose of plundering its occupants, or of
securing the valuables it contained. Putting his lamp on the table, he
went out upon the veranda, and looked all about him. The grounds were
very extensive, and a broad avenue led to the street. It was very dark;
but as he cast his eyes in the direction of the grand entrance to the
estate, he discovered some dark object in motion; but he lost sight of
it in a moment.

It was a living being, or it would not move, and he was certain that he
had made a discovery. Then two regrets flashed through his mind as he
stepped down from the veranda; the first, that he had not put on his
shoes before he left his chamber, and the second, that he had not taken

did not venture to explore it without any protection for his feet.

He peered into the gloom of the night with all his eyes, and listened
with all his ears for over an hour; and then, watchful and careful
officer as he was, there were five hundred chances against him to one
in his favor, of finding the intruder, and he reluctantly returned to
the mansion.

Like the other male occupants of the house, the lieutenant was provided
with a night-key. For one who had only just developed a tolerably
thriving mustache, Christy was a prudent and methodical young gentleman.
As a part of his method, he had a great many small drawers in his rooms,
and a dozen or more keys; but he had never lost them, for the reason
that he carried them chained to his nether garment. But he had two sets
of keys, one for the house, and one for the ship. He had ta
