As a result of this measure, the Progressive Stage System, through which convicts passed on their road to remission, was further defined and elaborated, and the Mark System as now in operation was instituted. Every convict was required to earn by actual labour a certain number of marks, proportioned to the length of his sentence, to enable him to purchase, as it were, any remission of sentence, or to advance from the lower to the higher class. Although misconduct would involve a forfeiture of marks, the marks are allotted simply for actual industry, as shown by the amount of work done, and are checked by the actual measurement of the work, where such is possible. The Directors, in their Report for 1865, comment on the introduction of the system as follows:-- "The value of the Mark System when honestly administered is, that it gives a tangible idea to the convicts of the value of their daily labour, and our endeavour has been to impress upon them that they must earn these marks to gain the advantages held out to them of remission of sentence and advancement in classes. Like any other system of recording the conduct and industry of convicts, the Mark System requires careful watching, to prevent it from degenerating into mere routine, and to avoid favouritism or intimidation. We have under existing circumstances the advantage that the convicts are employed in important Public Works, which admit of accurate measurement and valuation; and we think the checks we have adopted are sufficient to guarantee that whatever the convicts do earn will be earned by fair labour accompanied by good behaviour. It is very satisfactory to us to state, that although none of the officers of the English Convict Prisons had any previous experience of the working of the Mark System, which might naturally be expected to be regarded with some kind of suspicion, its success has far exceeded our expectations. The Governors and the subordinate officers have devoted themselves very zealously to master the principles and details of the Mark System, and have entered into the spirit of the measure with great zeal, and the testimony of the Governors to the beneficial results on the labour and industry of the convicts is very gratifying. The convicts themselves take a lively interest in the account of their marks, which they watch with earnestness, and fully avail themselves of the privilege of bringing before the Directors any grievance they think they have respecting them."
