On this subject many an enthusiast has speculated, and many a fine and beautiful theory has charmed the benevolent mind. The sacred orator from the desk, inspired by the genius of his faith, and warm amidst the holy fires of the altar, has often brought the miserable tenants of the dungeon within the sympathies of his weeping hearers. Clothed with the robes of state, the philanthropist has often urged the claims of prisoners upon the consideration of councils and legislatures. For eighteen hundred years have the altar and the throne sent abroad, in tones of commiseration, the suffering and neglected condition of prisoners; but what has been the result? Prisons are as numerous as ever, and almost every season sees a new one erected. The annual volume of crimes is as huge and black as ever. The gloom of these earthly hells is undissipated by the charm of operative benevolence. And though it is two thousand years since the foundations of christianity were laid in the earth--that heavenly principle which was to say to the prisoners, "go forth,"--the notes of its rejoicing ascend in faint association with the deep-toned sigh of despair and misery, which is hourly bursting from the grated cell. Alas! for the times. But why have the benevolent and christian spirits of every age laboured in vain, and spent their strength for naught? The answer is obvious. They have acted on a mistaken theory. They have confided in the integrity and benevolence of those to whose immediate care prisoners are committed, where nothing is more true than that prison keepers are, and ever have been, the cruelest of men. They have gone the whole round of experiment--imprisonment and hard labour, solitary confinement, transportation, stripes, cropping and branding--the whole machinery of torture and death has been put into various motion, in the ignorant hope of reforming a sinner by the sure and only means of making a devil. The science of architecture has been exhausted in experiments to construct a reformatory prison, as if the form of a cell could regenerate a vicious heart into virtue. Societies have been formed, books have been published, funds have been collected, and a "PRISON DISCIPLINE" has been put into practice, on the infatuated supposition, that a bad man can be made good by writing him a "VILLIAN" on every page that presents him to the public eye, and crushing him under a painful and torturing humiliation which would fire an angel with resentment, and make a John a Judas. Every sermon that is preached, every prayer that is made, every hymn that is sung in prisons, tells the convicts that they are sinners above all men, because they suffer such things; and it is by means like these, by audibly and impliedly thanking God that they are not like these publicans, that the ministers of mercy to prisons are labouring to reform the wicked.
