The time came at length when the old City Gaol must fall in with the steady and persistent march towards prison reform. The movement had been initiated by the legislative and certain improvements were made imperative, notably that which recognized the unalterable principle that every individual should be confined separately and singly in one cell or apartment. Already steps had been taken and public moneys voted to construct a prison on the most approved plan to serve as a model for all. The result was Pentonville, erected in 1842 at a great outlay and on such intelligent lines that in due course it fulfilled its first aim and became a model for imitation. Pentonville has been universally adopted as the best form of building and its system the best contrived to effect the chief desiderata of a penal establishment, such as coercion, repression and reformation. It is to be seen to-day with small variation in almost every country of the world and is generally considered the best type of prison construction. In England, jurisdictions were ready to recognize their duties and responsibilities and fine prisons arose in the large provincial cities and wide areas of population, although others still lagged behind deterred by parsimony and the lack of public spirit. Newgate, the gaol of the richest corporation in the world, was one of the latter and an official report published in 1850 animadverted strongly on its still unsatisfactory condition. Not much had been done to remedy the old defects; radical improvement was generally considered impossible. The great evil, however, had been sensibly diminished. There was no longer, or at worst but rarely, and for short periods, the same overcrowding. This was obviated by the frequent sessions of the Central Criminal Court, and the utilization of the two subsidiary prisons in Giltspur Street and Southwark. The prison population of Newgate was still subject to great fluctuations, but it seldom rose above two hundred and fifty or three hundred at the most crowded periods, or just before the sessional gaol delivery; and at its lowest it fell sometimes to fifty or sixty. These numbers would have still further decreased, and the gaol would have been almost empty, but for the misdemeanants who were still sent to Newgate at times on long terms of imprisonment, and for the transports, whom the Home Office was often, as of old, slow to remove. The old wards, day rooms and sleeping rooms combined, now seldom contained more than ten or a dozen occupants. Some sort of decorum was maintained in the day-time. Drinking and gaming, the indiscriminate visitation of friends, and the almost unlimited admission of extra food, had disappeared.
