Constitutions for the Colonies are now on the anvil; the discontented Colonies are all to be cured of their miseries by Constitutions. Whether that will cure their miseries, or only operate as a Godfrey's-cordial to stop their whimpering, and in the end worsen all their miseries, may be a sad doubt to us. One thing strikes a remote spectator in these Colonial questions: the singular placidity with which the British Statesman at this time, backed by M'Croudy and the British moneyed classes, is prepared to surrender whatsoever interest Britain, as foundress of those establishments, might pretend to have in the decision. "If you want to go from us, go; we by no means want you to stay: you cost us money yearly, which is scarce; desperate quantities of trouble too: why not go, if you wish it?" Such is the humor of the British Statesman, at this time.--Men clear for rebellion, "annexation" as they call it, walk openly abroad in our American Colonies; found newspapers, hold platform palaverings. From Canada there comes duly by each mail a regular statistic of Annexationism: increasing fast in this quarter, diminishing in that;--Majesty's Chief Governor seeming to take it as a perfectly open question; Majesty's Chief Governor in fact seldom appearing on the scene at all, except to receive the impact of a few rotten eggs on occasion, and then duck in again to his private contemplations. And yet one would think the Majesty's Chief Governor ought to have a kind of interest in the thing? Public liberty is carried to a great length in some portions of her Majesty's dominions. But the question, "Are we to continue subjects of her Majesty, or start rebelling against her? So many as are for rebelling, hold up your hands!" Here is a public discussion of a very extraordinary nature to be going on under the nose of a Governor of Canada. How the Governor of Canada, being a British piece of flesh and blood, and not a Canadian lumber-log of mere pine and rosin, can stand it, is not very conceivable at first view. He does it, seemingly, with the stoicism of a Zeno. It is a constitutional sight like few.
