d the same service to three of the iron bars that secured my
window, to which I climbed, partly by the assistance of my chair, and
partly by means of certain irregularities in the wall. All this was the
work of more than two hours. When the bars were filed through, I easily
forced them a little from the perpendicular, and then drew them, one by
one, out of the wall, into which they were sunk about three inches
perfectly straight, and without any precaution to prevent their being
removed. But the space thus obtained was by no means wide enough to
admit the passing of my body. I therefore applied myself, partly with my
chisel, and partly with one of the iron bars, to the loosening the
brick-work; and when I had thus disengaged four or five bricks, I got
down and piled them upon the floor. This operation I repeated three or
four times The space was now sufficient for my purpose: and, having
crept through the opening, I stepped upon a shed on the outside.

I was now in a kind of rude area between two dead walls, that south of
the felons' day-room (the windows of which were at the east end) and the
wall of the prison. But I had not, as formerly, any instruments to
assist me in scaling the wall, which was of considerable height. There
was, of consequence, no resource for me but that of effecting a
practicable breach in the lower part of the wall, which was of no
contemptible strength, being of stone on the outside, with a facing of
brick within. The rooms for the debtors were at right angles with the
building from which I had just escaped; and, as the night was extremely
bright, I was in momentary danger, particularly in case of the least
noise, of being discovered by them, several of their windows commanding
this area. Thus circumstanced, I determined to make the shed answer the
purpose of concealment. It was locked; but, with the broken link of my
fetters, which I had had the precaution to bring with me, I found no
great difficulty in opening the lock. I had now got a sufficient means
of hiding my person while I proceeded in my work, attended with no
other disadvantage than that of being obliged to leave the door, through
which I had thus broken, a little open for the sake of light. After some
time, I had removed a considerable part of the brick-work of the outer
wall; but, when I came to the stone, I found the undertaking infinitely
more difficult. The mortar which bound together the building was, by
length of time, nearly
