XVI. By neatness and cleanliness, by diversity of employment, by variety of contrivance, and above all, by that peculiarity of construction, which, without any unpleasant or hazardous vicinity, enables the whole Establishment to be inspected at a view, from a commodious and insulated room in the centre, the Prisoners remaining unconscious of their being thus observed, it should be his study to render it a spectacle such as persons of all classes would, in the way of amusement, be curious to partake of: and that, not only on Sundays, at the time of Divine Service, but on ordinary days, at meal-times, or times of work: providing thereby a _system of superintendance, universal, unchargeable and uninterrupted_, the most effectual and _indestructible_ of all securities against abuse. Such are the methods that have occurred to him for accomplishing that identification of "_interest with duty_," the effectuating of which, in the person of the Governour, is declared to be one of the leading objects of the Penitentiary Act.--[19 GEO. III. ch. 74.] The station of Gaoler is not in common account a very elevated one: the addition of Contractor has not much tendency to raise it. He little dreamt, when he first launched into the subject, that he was to become a suitor, and perhaps in vain, for such an office. But inventions unpractised might be in want of the inventor: and a situation, thus clipped of emoluments, while it was loaded with obligations, might be in want of candidates. Penetrated, therefore, with the importance of the end, he would not suffer himself to see any thing unpleasant or discreditable in the means. * * * * * _Outline of the Plan of Construction alluded to in the above Proposal._ The Building _circular_--about the size of _Ranelagh_--The Prisoners in their Cells, occupying the Circumference--The Officers, (Governor, Chaplain, Surgeon, &c.) the Centre. By _Blinds_, and other contrivances, the Inspectors concealed (except in as far as they think fit to show themselves) from the observation of the Prisoners: hence the sentiment of a sort of invisible omnipresence.--The whole circuit reviewable with little, or, if necessary, without any change of place. _One_ Station in the Inspection-Part affording the most perfect view of every Cell, and every part of every Cell, unless where a screen is thought fit occasionally and purposely to be interposed. Against _Fire_ (if, under a system of constant and universal inspection, any such accident could be to be apprehended,) a pipe, terminating in a flexible hose, for bringing the water down into the central Inspection-Room, from a cistern, of a height sufficient to force it up again by its own pressure, on the mere turning of a cock, and spread it thus over any part within the Building.
