England, then, should never have reproached us with slavery. The work was hers, and hers may yet be the dread retribution of avenging justice. Had the contest she provoked in the Trent affair then happened, the result might have been very different from her expectations. Instead of a ruined country, and divided Union, and God save the King played under the cross of St. George in Boston, New-York, and Philadelphia, she might have heard the music of Yankee Doodle, Hail Columbia, and the Star-Spangled Banner on the heights of Quebec, reechoed in fraternal chorus over the Union intended by God, under one government, of the valley of the lakes and the St. Lawrence. Looking nearer home, she might have beheld that banner, whose stars she would have extinguished in blood, floating triumphantly, in union with the Shamrock, over that glorious Emerald Isle, whose generous heart beats with love of the American Union, and whose blood, now as ever heretofore, is poured out in copious libations in its defense. Indeed, but for the forbearance of our Government, and the judgment and good sense of Lord Lyons, the conflict was inevitable. The hope was expressed by me in England that 'those glorious isles would become the breakwater of liberty, against which the surges of European despotism would dash in vain.' This was her true policy, justice to Ireland, successive reforms in her system, a further wise extension of the suffrage, with the vote by ballot, a cordial moral alliance with her kindred race in America, and a full participation, mutually beneficial, in our ever enlarging commerce. But her oligarchy has chosen coalition with the South and slavery, and war upon our Union and the republican principle. _Divide and conquer_ is their motto, SUICIDE will be their epitaph. England is now playing her part in the fourth act of the drama of slavery. During the first act, for more than a century, she was actively engaged in the African slave-trade, and in forcing the victims, as slaves, upon the colonies, against their protest. With the close of the first act came the American Revolution, when, in the truthful language of Mr. Jefferson, before quoted, England 'excited the slaves to rise in arms among us, and to purchase the liberty of which she had deprived them, by murdering the people on whom she had obtruded them.'
