in the constitutional, administrative and judicial organization of the various powers, in international law, commercial law and maritime law, in the history of treaties and in commercial and political geography, in political economy, and in the German and English languages. They have to serve three years abroad or attached to some ministerial department before they can enter for the examination which entitles them to an appointment as attache or as _consul suppleant_. This assimilation of the consular to the diplomatic service remains peculiar to France.[3] In Germany it was enacted by the law of February 28, 1873, that German consuls must be either trained jurists, or must have passed special examinations. The result of this system has been the establishment throughout the world of an elaborate network of trained commercial experts, directly responsible to the central government, and charged as one of their principal duties with the task of keeping the government informed of all that may be of interest to German traders. These annual consular reports were from the first regularly and promptly published in the _Deutsche Handelsarchiv_, and have contributed much to the wonderful expansion of German trade. The right to establish consuls is now universally recognized by Christian civilized states. Jurists at one time contended that according to international law a right of "ex-territoriality" attached to consuls, their persons and dwellings being sacred, and themselves amenable to local authority only in cases of strong suspicion on political grounds. It is now admitted that, apart from treaty, custom has established very few consular privileges; that perhaps consuls may be arrested and incarcerated, not merely on criminal charges, but for civil debt; and that, if they engage in trade or become the owners of immovable property, their persons certainly lose protection. This question of arrest has been frequently raised in Europe:--in the case of Barbuit, a tallow-chandler, who from 1717 to 1735 acted as Prussian consul in London, and to whom the exemption conferred by statute on ambassadors was held not to apply; in the case of Cretico, the Turkish consul in London in 1808; in the case of Begley, the United States consul at Genoa, arrested in Paris in 1840; and in the case of De la Fuente Hermosa, Uruguayan consul, whom the _Cour Royale_ of Paris in 1842 held liable to arrest for debt. In the same way consuls are often exempt from all kinds of rates and taxes, and always from personal taxes. They are exempt from billeting and military service, but are not entitled (except in the Levant, where also freedom from arrest and trial is the rule) to have private chapels in their houses. The right of consuls to exhibit their national arms and flag over the door of the bureau is not disputed.
