The Greek metropolis sometimes sent priests to its colonies, and bishops are long appointed by the mother church. During the three centuries of Peruvian dependence fully one in seven bishops--one hundred and five against seven hundred and six--were native Americans. Canada seems to have at length arrived at complete independence and appoints Canadians. In Australasia and South Africa the metropolitans and most of the suffragans are still nominated in England; a dean may be transferred from one colony to another as a bishop; or a small and poor diocese may elect one of its incumbents. Local jealousies and possibly the absence of a commanding spirit combine with the desire to have the best the home church can afford to give or the colonial church procure to dictate the extraneous selection. The stream of ecclesiastical culture flows likewise through the immigration or importation of ministers of all denominations. It means, among Catholics as among Protestants, the periodical addition to the spiritual wealth of the colonies of an amount of talent and high character which they would have been slow to acquire by natural growth. University or collegiate professors are for quite as long appointed by a committee of selection in the mother country. Such men--some of them brilliant, laborious, enthusiastic--are a real acquisition to communities immersed in material pursuits and cut off from the movement of science in Europe, and their position is deservedly high and well remunerated. Doctors, lawyers, artists, teachers, experts in many departments, place the colonies in the same position relatively to less-favored communities, as the sons of a squire relatively to the sons of an artisan. In this respect, as in most others, a colony follows the example of the mother country. The introduction of literature, the sciences and the arts into the mother-land was to a large extent at all stages in its history the work of aliens. It is so still; the names of Bunsen, Rosen, Max Müller, Goldstücker, Aufrecht, and a score of others, are proofs that men as well as things that are ‘made in Germany’ are still imported into England. To descend to the mechanical arts, “the ranks of skilled workmen in America were and are renewed from the more fertile soil of Europe”; even the workmen in the Portland stone-quarries are imported from England. The second mode in which foreign culture was introduced into the mother-land in common with all others--visits made abroad for discipleship or instruction--has all along been, and is now increasingly, maintained. Colonial students go to Europe to be trained in medicine and law. Experts go to become acquainted with advances in science and medicine, or with recent improvements in mechanical processes. The wealthier colonists who spend occasional seasons in Europe bring back new (or antiquated) social or political notions, and Americans who thus try to import into the United States an aristocratic style of living have
