If the hum of the American seaboard is in part the echo of sentiments from abroad, here the unmixed voice of America may be heard, as it pronounces that it is too late to wrest territory from the United States by prevarication, by menace, or by force. From the English dockyards it is a long voyage to San Juan; the only good land route across the continent lies south of Lake Superior; in a few years there will be three Ohios on the shores of the Pacific. It is England's interest as well as duty to give effect to the treaty as it was interpreted by her own minister to ours. Your voices on this memorable day give the instruction to our own Government to abide by the treaty faithfully, on the condition that Britain will do the same; but the treaty must bind neither party or both--must be executed in good faith or canceled. The men who honor the memory of Perry will always know how to defend the domain of their country. Has any European statesman been miscounting the strength of this nation, by substituting a reminiscence of our feeble confederation for the present efficient and almost perfect organism of the body politic? Has any foreign ruler been so foolish as to listen with credulity to the tales of impending disunion? Every man of the people of Ohio, this great central highway of national travel, will, without one exception, tell the calumniator or the unbeliever that the voices of discontent among us are but the evanescent vapor of men's breath; that our little domestic strifes are no more than momentary disturbances on the surface, easily settled among ourselves; that the love of Union has wound its cords indissolubly round the whole American people. So, then, our last word shall be for the Union. The Union will guard the fame of its defenders, and ever more protect our entire territory; it will keep alive for mankind, the beacon lights of popular liberty and power; it will dissuade nations in a state of unripeness from attempting to found republican governments before they spring up naturally by an inward law; and its mighty heart will throb with delight at every true advance in any part of the world, toward republican happiness and freedom.
