The censorship of the press is nnother BÃTecteuM barrier to ingress of knowlsdge. It surrounds the empire with a sjloomy wall, which can neither be undermined nor overleaped. Twclve public ;ensors are established at Vienna, to some af whom every book published within the empire, whether original or reprinted, must be refered. And if there be any allusion even, to reform, either in the reigion or the politics of .the country, the 3ook is summarily condemned. The same rigid censorship ex'ends to all foreignjournals, which are permitted to enter the empire. No man can take any foreign publication without permission of the censors. And no publication which does not advocate despotic principies can be taken at all. The Austrian Observer, which is published at the capital, is the organ of the jovernment. It contains only tose items of foreign intclligence which the Emperor is willing that hissubjects should know. And its voice is obsequiously echoed by the journals which, also under vigilant cenorship, are established in the provinces. In the whole Austrian empire, containing a population of about thirty millions of inhabitants, there are but eighty one journals published; anumber probably exceeded by the single city of New York.
