It has been abundantly shown that the anticipation of some speculative persons, that the course of the Gulf Stream, and consequently the climate of Western Europe, might be altered by cutting through the isthmus, and thus connecting the Atlantic and Pacific oceans, was altogether erroneous. No change whatever in the direction, rate of motion, or temperature of the great current has been observed. It is too majestic a movement to be so affected. It is remarkable how entirely mistaken, also, those croaking prophets were, who formerly supposed that much addition to the old United States would make a cumbrous and impracticable political aggregate. Since the principle that only honest men shall be placed in public offices has been adopted throughout the nation, local administration of local affairs harmonizes so well with a central national government controlling general interests, that all works smoothly yet; even with the addition of the three great States which once formed the Dominion of Canada, and the outlying territories of Greenland, Labrador, Hawaii, Cuba, and St. Domingo. A motion made in the House last year, but then postponed rather than defeated, will probably come up again in Congress at this session: namely, to hold the meeting of Congress every third year in San Francisco. Alternation between Washington and St. Louis has now worked well for eleven years; and Western men are getting clamorous about their right to the same privilege in turn. Capitalists of San Francisco offer to contribute five millions of dollars towards the erection of the western Capitol, besides building and fitting out a Presidential mansion in their city. This is handsome; and, since the central Capitol at St. Louis, now nearly finished, has involved the expenditure of about twelve millions, such liberality may be needful for the success of the project. One of the California Senators has written an article on this topic in the last number of the _North American Review_. He proposes, among other things, that a statue of Abraham Lincoln shall be erected in front of the Capitol at St. Louis, and one of William Penn at that of San Francisco. At the three seats of government we shall then have perpetuated the memory of the three noblest and most era-making of American statesmen: Penn, representing the grandeur and security of Christian justice and peace; Washington, loyalty to national independence and republican institutions; Lincoln, the triumph, by sacrifice, of liberty throughout our continent. * * * * *
