We know nothing of the causes that have led to this memorable and momentous event, except that apparently differences of opinion prevailed among the members of the Ministry in reference to the corn-laws. We shall not believe, until we hear it from their own lips, that any portion of the Cabinet have advocated any scheme fraught with danger and injustice to the best interests of the country: nor shall we indulge in any conjecture as to the real nature of the policy that may have been under discussion, where conjecture must be so vague, and where it must so soon give place to authentic information. We shall merely say, that any measure calculated to place agriculture and industry generally, in a disadvantageous and defenceless position, must have met with our unfactious, but firm, opposition. If ever the day should come, when protection, by common consent, were to be withdrawn, truth compels us to declare, that there is no one by whose hand we should desire to see that painful and dangerous operation performed so much as Sir Robert Peel;--not because we should be insensible to all the awkward and painful embarrassments of such a change of course; but simply, because we are bound to say, that there is no other man of whose knowledge, skill, and sagacity we have the same opinion. By none we think could the fall be so much broken, or the transition made so smooth, or so little injurious. Certain it is, that a measure of total and immediate abolition _from the Whigs, incompetent and incapable as they have been proved_, would be a calamity of which the magnitude can scarcely be estimated by the most gloomy imagination. We are far, however, from contemplating the necessity or possibility of such a policy from any Ministry whatever.
