The population, 1,868,328, is nearly three hundred thousand less than at the beginning of the Great War. Vienna is the capital and chief city of Austria. It is beautifully located on the Danube river and is laid out with broad avenues that are planted with trees. Just below the city the Alps and the Little Carpathians come to the banks of the river and form a narrow pass known as the Austrian Gate. The museums in Vienna have wonderfully valuable art and natural-history collections, and this city has long been one of the leading musical centers of the world.
