NEWGATE: THE CHAPEL.
On either side of the pulpit in the chapel of grim Newgate Gaol sit the male prisoners, on the low forms behind the railings while the female prisoners occupy the gallery, shown in our picture. This gallery is so contrived that the women have an uninterrupted view of the preacher from between the tall, slanting boards, but cannot see their fellow-prisoners of the other sex. In the corner to the right of the preacher is a box reserved for the Governor of the Gaol, and the Chief Warder has a seat beneath. Between the stove and the reading-desk below the pulpit is the harmonium that leads the musical part of the service. The pulpit, it will be seen, faces the communion table.
