Berlin, not being a fortified city, was spared at least the misery of a siege. After the downfall of Napoleon, Prussia and its capital resumed their mission of absorption and expansion. The "Customs Union" accelerated the pace. In 1862 the population was 480,000; in 1867, 702,437; in 1871, 826,341. At present it is in excess of Vienna. The Austrian and French wars have given to its growth an almost feverish impulse. [Footnote 2: The Friederichsstadt and Dorotheenstadt are those parts of the town with which the tourist is most familiar as places of residence and shopping; Cöln is the island on which stand the castle and the two museums; Old Berlin is the part beyond the Spree.] A comparison of Berlin and Vienna in their present state will suggest many reflections. We have seen that they resemble each other in origin, rate of growth and actual size. In their composition, however, they differ widely. The population of Berlin is homogeneous, devotedly attached to the Hohenzollern dynasty, enterprising in trade and manufactures, thrifty and economical. It spends far less than it earns. For upward of half a century it has been subjected to the most careful military and scientific training. Moreover, Berlin is the geographical and political centre of a thoroughly homogeneous realm. We cannot afford to encourage any delusions on this point. It has become of late the fashion among certain French writers and their imitators to sneer at the Prussians as semi-Slaves, to call them Borussians, and contrast them with the so-called Germans proper of Bavaria, Swabia and the Rhine; whereas the fact of ethnography is that the Prussians are an amalgamation of the best--that is, the hardiest and most enterprising--elements of all the German districts. The purest blood and the most active brains of the old empire left their homes on the Main and the Weser to colonize and conquer under the leadership of the Teutonic order. The few drops of Slavic blood are nothing in comparison. Slavic names of towns and villages do not prove Slavic descent; else, by like reasoning, we should have to pronounce "France" and "French" words implying German blood, and "Normandy" an expression for Norse lineage. So far from being composite, Berlin is ultra German. It is more national, in this sense, than Dresden, where the Saxon court was for generations Polish in tastes and sympathies, and where English and American residents constitute at this day a perceptible element; more so than Bremen and Hamburg, which are entrepôts for foreign commerce; more so than Frankfort, with its French affiliations. The few Polish noblemen and workmen from Posen only serve to relieve the otherwise monotonous German type of the city. The French culture assumed by Frederick the Great and his contemporaries was a mere surface varnish, a passing fashion that left the underlying structure intact. Furthermore, Berlin is profoundly Protestant. The Reformation was accepted here with enthusiasm, and its
