It is the recognised duty of all ambassadors, military and naval attaches, and consuls, to collect information in any possible way, and to pay for it, and it may be guessed that their staff of informers is a large one. Further, under the heading of diplomatic spies must be included the internal espionage of Germany, by means of which all the various members of the Royal Family at Berlin are kept under surveillance and reported on. Potsdam neglects nothing in this way, as the Memoirs of Louise of Saxony prove beyond dispute. Some time ago the head official of the system of internal espionage in Germany was exposed at the height of his success, and thus an idea of the actual working and extent of the system was rendered obtainable. The person in question, Colonel Baron von Tausch, established on his own account a _bureau d'espionage_, and carried his investigations to such a point that the Minister of Foreign Affairs, after having made representations to the Kaiser, took action against Von Tausch for libel and conspiracy. From evidence made public at the trial it appeared that Von Tausch, who wished to obtain information for his master with regard to the nationalist movement in Prussian Poland, had ordered Baron von Luetzow to win the affections of the daughter of a Polish noble who was in the front of the nationalist movement, and, by this means, to gain the confidence of the girl's father. Luetzow complied, won the heart of the girl and the confidence of her father, and then returned to Berlin, leaving the girl behind. This was one instance of the methods used to obtain information. Correspondence, produced in court, introduced into the case the name of Count Philip zu Eulenberg, sometime German Ambassador at Vienna. Eulenberg, one of the boy-friends of the Kaiser, developed into a moral degenerate, and the whole of the Berlin Court--at least, all that part of it which had the best interests of the Kaiser and the Empire at heart--deplored the retention of Eulenberg in the imperial favour. In 1907 Eulenberg's degeneracy was exposed by Maximilian Harden, editor of _Die Zukunft_, who was prosecuted for his audacity in attacking one of the Emperor's friends, and forced the prosecution to withdraw by stating that he had enough correspondence in his possession to ruin the reputations of members of the Imperial family and half the officers of the Imperial Guards. The correspondence produced at Von Tausch's trial was chiefly noteworthy for a letter addressed by the chief of the secret police to Eulenberg, in which the former claimed that he had successfully accomplished espionage work which, he hoped, would have the effect of mining the Foreign Minister for good. Shortly after, as evidence showed, Eulenberg sent to Von Tausch the ribbon of a high Austrian Order which had been presented by the Austrian Government, evidently as recognition of services performed in connection with the German Foreign Minister.
