If the war were over in 1865 there would probably be 600,000 men under arms, and there would be at least 200,000 more men in the States who had served, and would take up arms against England with alacrity. A considerable proportion of that army would indeed seek their discharge, and go quietly back to their avocations; but the Irish, Germans, &c., to whom the license of war was agreeable, would not be unwilling to invade Canada, and a percentage of Americans would doubtless eagerly seek for an opportunity of gaining against a foreign enemy the laurels they had not found whilst contending with their fellow countrymen. Commerce indeed would suffer--the Americans would find for the first time what it was to enter upon a quarrel single-handed with the British nation. They have hitherto met only the side blows and stray shots of the old mother country--and they believe they have encountered the full weight of her arm, and the utmost extent of her energies. The wicked men who are striving to engage the two States in a quarrel which would cover the seas of the world with blood and wreck, cannot be deterred from their horrible work by any appeals to fear or conscience; but the influence of the past, and of the Christian and civilised people of the ex-United States will, it is to be hoped, defeat their efforts, seconded though they may be by the prejudice, religious animosity, and national dislike of a portion of the people. If the war party prevail they will have no want of pretexts--the San Juan question alone would suffice them if they had not a whole series of imaginary wrongs to resent arising from the incidents of the present war, and a multitude of claims to prefer to which England can never listen.
