His studies of a technical character may be said to be confined to Topography, Trigonometry, Naval Construction, Military Fortification and Drawing. His tutors are invariably taken from the ablest experts in their subjects. Supposing a Secret Service be sent to Antwerp to study the forts and report upon them, he must be in a position to give correct estimates of heights, angles, distances, ground-lay; he must, therefore, be a surveyor the accuracy of whose intuitions must to a large extent cover the work of the theodolite or the transit-compass. In the case of the spy, for instance, who reported to Berlin upon the Forth Bridge, the work had to be performed without arousing the attention or the suspicions of officials; the man in question effected his measurements by pacing, by observing angles and by subsequent triangulation, the result being highly creditable to his training, for he judged the required measurements to within yards and feet in distances and heights, respectively. It may be objected that this was wasted time, since these facts are available to anyone. The General Staff at Berlin was taking no chances, however. Its object in sending its man to examine the Forth Bridge was solely to find out how many men could be so disposed, in the vicinity of the structure, as to blow it up at a given signal, what was the geological nature of the foundation-shafts, how much dynamite would be required to destroy the bridge. And Berlin wanted to _know_. So too with regard to all matters military and naval, as we shall presently show. There is, indeed, no time for leisure and no laggards are allowed to remain very long upon the roster of the General Staff's Secret Service College. Anything more complete or thorough, it would be hard to imagine, and but for the sinister aims and objects of the whole curriculum, it would be difficult to picture anything more admirable or workmanlike in its organic perfection. The work entitled _Secrets of the German War Office_ written by Mr Graves has, as most people are by this time aware, been disavowed by the Berlin authorities as being the work of what Americans call "a good guesser." This, it must be seen, was the only course open to the German Staff, and their disclaimers in no way discount the value of their ex-agent's story when he touches upon purely departmental and organic details connected with the Steinhauer bureau. He tells us himself that he served for twelve years in the German Secret Service which has three distinct branches—that of the Army, that of the Navy and the Personal Corps. The General Staff of Berlin controls the Secret Service departments dealing with both military and naval affairs, while the Personal department is directed from the Foreign Office and is really under the direct eye and touch of the German Emperor himself. The military and naval sections deal with the procuring of hidden and secret information in regard to armaments, plans, new inventions and codes. The Personal
