oom with an oven for the
purpose of purifying foul linen. The upper story contains over the
entrance gate the drop room: on each side are receiving cells, two for
males and two for females, a searching room for the surgeon, and the
prison wardrobe; directly over the drop room on the lead flat is the
place where the more heinous malefactors expiate their crimes. The
bastion on the right hand contains a building, on the ground floor and
in the centre of which is the wash-house and laundry, and in front the
drying ground; at each end of this building are the airing grounds for
the sick prisoners, and on the second floor are the male and female
infirmaries, separated by a strong partition wall. The left hand bastion
contains the millhouse, stable, and a room for the van which takes the
prisoners to the town hall in the assize time; over these three rooms
are the mill chamber and hay-loft. The horizontal wind vane on the roof
of this building is to assist the prisoners when there is not a
sufficiency of them sentenced to the tread-wheels; by shutting the
louvre boards of the arms it then produces employment for the prisoners
when there is no corn in the mill to grind. In the remote bastion are
seen the tread-wheels on which the prisoners are employed in keeping up
a constant retrograde motion, which works the machinery in the millhouse
by means of an iron shaft with universal joints concealed below the
surface of the ground.

Here are four prison wings in the building, the right hand one contains
in one ward common debtors, and in the other unconvicted men felons, not
capital. The second wing on the right contains on one side unconvicted
men felons, and unconvicted women felons for capital offences on the
other. In the first left hand wing there is on the first side the master
debtors, and on the other the court of conscience debtors; the second
wing on the left contains on one side men misdemeanors, and on the other
convicted men felons. There are two day-rooms in each of the four wings,
and four condemned cells and four solitary ones in the back towers;
there is also fourteen airing yards between the four wings, six of which
are sunk three feet below the others, to enable the governor from the
inspection gallery of his house to overlook the tread-wheels, millhouse,
and infirmary; those yards are descended by stone steps, in each there
is a day room, and they are appropriated to the following prisoners,
namely, women debtor
