But in truth all such general regulations of the kind here supposed, entering into all the detail of domestic economy, and prescribing the precise quantum of food, clothing, labour, punishment, and medical care, must be, in their own nature, inherently defective. The quantity of food which they should direct, might in some cases be greater, in others less, than would be necessary; accordingly as the land which the Negroes had for growing their own provisions was more or less in quantity, more or less productive. Again, the medical care, the labour, the instruction, the discipline, the correction which might be called for on some estates, would not be required on others. And then all these provisions, so vexatious and invidious in their nature, were to be observed, not merely gratuitously, but it was to be expected that people would submit to them, would lend themselves to the enforcing of them, for the purpose of accelerating the period of abolition; an event which they had frankly declared they conceived would be in the highest degree injurious to their interests. Surely no credulity could be sufficient to make any one believe that laws of such a kind, and for such a purpose, and with such a premium on obeying them, could ever be carried into execution. [Sidenote: Proofs subsequently furnished, that no hope from Colonial Legislatures.] But if these and other arguments rendered it abundantly clear, when the question was first discussed, that the colonial legislatures neither could nor would apply any adequate reform to the existing abides, so as effectually to cooperate in measures for the abolition of the Slave Trade, there is now at least no ground for doubt on that head. The question has been since brought to the test of experiment. For, an endeavour to obtain the concurrence of the colonial legislatures has since been made under the most favourable circumstances of which the nature of the case could possibly admit; and yet it is not saying too much to declare, that the endeavour has utterly failed.
