day-room, which looked that way, the room itself being immediately over
the range of dungeons. I perceived that it was bounded by a wall of
considerable height, which I was told by my fellow-prisoners was the
extremity of the jail on that side, and beyond which was a back-lane of
some length, that terminated in the skirts of the town. Upon an accurate
observation, and much reflection upon the subject, I found I should be
able, if once I got into the garden, with my gimlets and piercers
inserted at proper distances to make a sort of ladder, by means of which
I could clear the wall, and once more take possession of the sweets of
liberty. I preferred this wall to that which immediately skirted my
dungeon, on the other side of which was a populous street.

I suffered about two days to elapse from the period at which I had
thoroughly digested my project, and then in the very middle of the night
began to set about its execution. The first door was attended with
considerable difficulty; but at length this obstacle was happily
removed. The second door was fastened on the inside. I was therefore
able with perfect ease to push back the bolts. But the lock, which of
course was depended upon for the principal security, and was therefore
strong, was double-shot, and the key taken away. I endeavoured with my
chisel to force back the bolt of the lock, but to no purpose. I then

no longer opposed to my wishes.

Thus far I had proceeded with the happiest success; but close on the
other side of the door there was a kennel with a large mastiff dog, of
which I had not the smallest previous knowledge. Though I stepped along
in the most careful manner, this animal was disturbed, and began to
bark. I was extremely disconcerted, but immediately applied myself to
soothe the animal, in which I presently succeeded. I then returned along
