The plan which has most largely and most deservedly attracted public attention, is that of Captain Maconochie, known by the name of the "Mark System." Captain Maconochie was superintendent of the penal establishment at Norfolk Island, where he had constantly about 2000 prisoners under his command. This office he held for eight years, and had, consequently, the most favourable opportunity of observing the practical working of the old system. Finding it to be defective, and injurious in every particular, he tried, with certain unavoidable modifications, a plan of his own, which, as he asserts, succeeded beyond his expectation. Having thus proved its practicability in Norfolk Island, and satisfied himself of its advantages, he wishes now to introduce it into England; and, with a view of obtaining a favourable hearing and efficient support, he has procured it to be referred to a committee of the "Society for Promoting the Amendment of the Law." The committee have reported in its favour; and their report, which is said to have been drawn up by the learned Recorder of Birmingham, contains so concise and clear a statement of the Captain's plan, that we take leave to extract a portion of it:-- "Captain Maconochie's plan," says Mr M. D. Hill, "had its origin in his experience of the evil tendency of sentences for a time certain, and of fixed gratuitous jail rations of food. These he practically found opposed to the reformation of the criminal. A man under a time-sentence looks exclusively to the means of beguiling that time. He is thereby led to evade labour, and to seek opportunities of personal gratification, obtained, in extreme cases, even in ways most horrible. His powers of deception are sharpened for the purpose; and even, when unable to offend in act, he seeks in fancy a gratification, by gloating over impure images. At the best, his life stagnates, no proper object of pursuit being presented to his thoughts. And the allotment of fixed gratuitous rations, irrespective of conduct or exertion, further aggravates the evil, by removing even the minor stimulus to action, furnished by the necessity of procuring food, and by thus directly fostering those habits of improvidence which, perhaps even more than determined vice, lead to crime.
