Now, at last, in the fulness of time, in our own day, by the labors of men of Peace, by the irresistible cooperating affinities of mankind, nations seem to be visibly approaching--even amidst tumult and discord--that Unity so long hoped for, prayed for. By steamboat, railroad, and telegraph, outstripping the traditional movements of government, men of all countries daily commingle, ancient prejudices fast dissolve, while ancient sympathies strengthen, and new sympathies come into being. The chief commercial cities of England send addresses of friendship to the chief commercial cities of France; and the latter delight to return the salutation. Similar cords of amity are twined between cities in England and cities in our own country. The visit to London of a band of French National Guards is reciprocated by the visit to Paris of a large company of Englishmen. Thus are achieved pacific conquests, where formerly all the force of arms could not prevail. Mr. Vattemare perambulates Europe and the United States to establish a system of literary international exchanges. By the daily agency of the press we are sharers in the trials and triumphs of brethren in all lands, and, renouncing the solitude of insulated nationalities, learn to live in the communion of associated states. By multitudinous reciprocities of commerce are developed relations of mutual dependence, stronger than treaties or alliances engrossed on parchment,--while, from a truer appreciation of the ethics of government, we arrive at the conviction, that the divine injunction, "Do unto others as you would have them do unto you," was spoken to nations as well as to individuals.
