The Abbé Wetterlé showed in his lecture how every German, through his civil and military education, has become a potential spy; how, on going forth to spend his holidays in France or elsewhere abroad, he could not help being the active agent of those directors of his conscience, the Pan-Germanists. "Recollect, everywhere and always, that you belong to the supreme race," they said to him, through their newspapers, pamphlets, and tracts. "Even if you know the language of the country where you are travelling, speak nothing but German. Never put up at any hotels but those kept by Germans, and amongst these choose only the ones kept by compatriots who you know have preserved all their attachment for the Fatherland. Insist in these establishments that they serve you with German products, and that the bill of fare is drawn up in your native tongue. Drink only beer imported from Germany. In the shops buy only those goods which bear the mark 'Made in Germany.' Praise wherever you go German industry, German methods, German science. To keep your feet on the right path, we will supply you with guides, in which you will find every needful address. Our good counsel will accompany you everywhere. And thus, whilst amusing and instructing yourself, you will render signal service to your country and will become a pioneer of Germanism in those countries which we wish, progressively, to dominate. Moreover, _never forget in the course of your travels that you can make a thousand useful observations. Note down what you see and send us the information you collect._ Details apparently the most insignificant may be of use to our industrial, commercial, and patriotic societies. Finally, strengthen the patriotic feeling with our compatriots established abroad. Tell them that Germany does not forget them, and that it is to their interest to remain in close relations with it. If you act in this way--and you cannot do otherwise, for we shall keep a sharp eye on you--you will contribute largely to the glory of Germany, which to-morrow will dominate the world." This picture is in no way exaggerated. Identical language was addressed to German tourists by the Pan-Germanist Association and the Deutschtum im Ausland Society, and the guides they published inculcated the principles of the most barefaced espionage.
