In February last we reviewed with great care all the evidence which we could collect regarding the West Indian interest. The conclusion to which we arrived was contained in the following paragraph:—“And what is it that our colonists ask? What is the extravagant proposal which we are prepared to reject at the cost of the loss of our most fertile possessions, and of nearly two hundred millions of British capital? Simply this, that in the meantime such a distinctive duty should be enforced as will allow them to compete on terms of equality with the slave-growing states. Let this alone be granted, and they have no wish to interfere with any other fiscal regulation. And what would be the amount of differential duty required? _Not more, as we apprehend, than ten shillings the hundredweight._” Having hazarded this statement so early, it was certainly gratifying to find that an impartial committee of the House of Commons, reporting four months later, had, after a full investigation of the whole case,—and of course with official documents before them, the correctness of which could not admit of a doubt,—arrived at precisely the same result. The proposition for a differential duty of ten shillings, which was finally agreed to by the committee, was actually made by a member whose general opinions are understood to lean towards the side of free trade,—we mean Sir Thomas B. Birch, one of the representatives for Liverpool. This resolution of course implied a direct condemnation of the Whig Act of 1846, which the West Indians bitterly complained of as a flagrant breach of faith, and as having put the coping-stone on their misfortunes. It was the resolution of an independent and intelligent parliamentary committee, founded upon a mass of evidence derived from every quarter; and in a matter of this sort, wherein so vast an interest as that of our most valuable colonies was concerned, it might have been expected that the report would be treated with deference, even though it might in some degree impugn the sagacity of a prime minister, by exposing the results of his former reckless legislation. Such was not the case. Had the seven wise men of Greece sate upon that committee, their report would have been utterly indifferent to Lord John, who immediately came forward with a counter-scheme, which had not even the merit of consistency to give it colour. He proposed a new sliding-scale of duties, the result of which will be, that next year the colonists will have a protection against the slave-owners of seven shillings in the article of clayed, and five-and-sixpence in that of muscovado sugar,—the boon to taper away annually, until, in 1854, the protective duty will be reduced to three shillings on the one article, and two shillings upon the other. This is the doom of the West Indies,—and we expect nothing less than an immediate stoppage of the supplies for the maintenance of the colonial governments. Robbed as they have been,
