We now come to enquire into the condition of mind produced by the seclusion (limited in duration as Lord Grey limits it) which is purchased at this great cost in money, and this greater cost in stupendous injustice. That it is a consummation much to be desired, that a respectable man, lapsing into crime, should expiate his offence without incurring the liability of being afterwards recognised by hardened offenders who were his fellow-prisoners, we most readily admit. But, that this object, howsoever desirable and benevolent, is in itself sufficient to outweigh such objections as we have set forth, we cannot for a moment concede. Nor have we any sufficient guarantee that even this solitary point is gained. Under how many apparently inseparable difficulties, men immured in solitary cells, will by some means obtain a knowledge of other men immured in other solitary cells, most of us know from all the accounts and anecdotes we have read of secret prisons and secret prisoners from our school-time upwards. That there is a fascination in the desire to know something of the hidden presence beyond the blank wall of the cell; that the listening ear is often laid against that wall; that there is an overpowering temptation to respond to the muffled knock, or any other signal which sharpened ingenuity pondering day after day on one idea can devise: is in that constitution of human nature which impels mankind to communication with one another, and makes solitude a false condition against which nature strives. That such communication within the Model Prison, is not only probable, but indisputably proved to be possible by its actual discovery, we have no hesitation in stating as a fact. Some pains have been taken to hush the matter, but the truth is, that when the Prisoners at Pentonville ceased to be selected Prisoners, especially picked out and chosen for the purposes of that experiment, an extensive conspiracy was found out among them, involving, it is needless to say, extensive communication. Small pieces of paper with writing upon them, had been crushed into balls, and shot into the apertures of cell doors, by prisoners passing along the passages; false responses had been made during Divine Service in the chapel, in which responses they addressed one another; and armed men were secretly dispersed by the Governor in various parts of the building, to prevent the general rising, which was anticipated as the consequence of this plot. Undiscovered communication, under this system, we assume to be frequent.
