Description
'The new lock up house, forming part of the police station and house for the chief constable, contains three cells ... The cells are in a separate building at the end of the police yard, but the chief constable said he could hear from his house the slightest noise in the cells .. One of the cells is not used, as it contains the warming apparatus, the steam from which renders the floor damp. The other two cells are dry, properly warmed and ventilated and apparently secure; they are lighted by small unglazed windows ... There is a kind of guard bed in each cell, with rugs for bedding, but the supply of rugs was scarcely sufficient.'
