The literary treasures of England,—accumulating from Alfred, Bede, and Chaucer, through a succession of enlightened ages, swelling up in their onward progress the vast catalogue of science, connecting with their recorded mental wealth the names of men who consecrated with their genius the age in which they flourished,—did less for her commercial interest, throughout all those periods, than has the United States in less than fifty years. Enterprise came forth under the light of liberty, and extended its operations to every department of trade, commerce, art, and science. England became alive to the fact that a new people had created and given a living principle to the mechanical workings in the world of trade and commerce. Its operations gave vigor to action, and infused a spirit into merchants and traders which, heretofore, followed in the wake of _monarchial follies_, “As peddlers from town to town.” We purpose to speak now of the post being a branch of the government, and, in some respects, one of the most important. The post-office department should be, but it is not, a social agent. The peculiar character of a republican government is such that the post becomes essentially a great political one. Its connection with an administration is one of the links connecting party with its political interests, and which becomes broken immediately on the success attending that of a rival. It is rotary in its motion; hence the various changes which necessarily occur at elections have a tendency to retard, rather than advance, the postal system on its road to perfection. Indeed, it is not assuming too much if we say that civil liberty, practically speaking, partly consists in these changes; for opposition is an essential and vital element of such liberty, and opposition, with these possible changes, would have little or no meaning. If, however, they were limited to the heads of the department, and not extending down to the humblest workers in the office, the evil effects ever attending on such changes would not so materially operate against its interests, and, of course, that of the community. A general sweep of the employees of any one State or government department makes the whole system a gigantic political, rather than what it should be, a social, institution. In whatever light, however, we view the post-office, it presents to us a subject of the highest interest. Connect it with commerce, and it assumes the power of a “Merlin,” whose magic wand, raised in the ages of superstition, astonished the world! Connect it with the arts, and nations are brought together by the mere stroke of the pen! Associate it with science, religion,—in fact, with any of the prominent features which make up civilized life,—it becomes at once the great medium through which their mysteries and developments are made manifest to all.
