One of the earliest methods of creating disorder in American munition plants and other industrial establishments engaged in war work was through labor disturbances. With that end in view a general German employment bureau was established in August, 1915, in New York City. It had branches in Philadelphia, Bridgeport, Pittsburgh, Cleveland, Chicago and Cincinnati. These cities at that time were the centers of industries engaged in furnishing munitions and war supplies to the Entente allies. Concerning this enterprise Ambassador Dumba writing to Baron Burian, Foreign Minister of Austria-Hungary, said: A private German employment office has been established which provides employment for persons who have voluntarily given up their places, and it is already working well. We shall also join in and the widest support is assured us. The duties of men sent from the German employment offices into munition plants may be gathered from the following frank circular issued on November 2, 1914, by the German General Headquarters and reprinted in the _Freie Zeitung_, of Berne. GENERAL HEADQUARTERS TO THE MILITARY REPRESENTATIVE ON THE RUSSIAN AND FRENCH FRONTS, AS WELL AS IN ITALY AND NORWAY In all branch establishments of German banking houses in Sweden, Norway, Switzerland, China and the United States, special military accounts have been opened for special war necessities. Main headquarters authorizes you to use these credits to an unlimited extent for the purpose of destroying factories, workshops, camps, and the most important centers of military and civil supply belonging to the enemy. In addition to the incitement of labor troubles, measures must be taken for the damaging of engines and machinery plants, the destruction of vessels carrying war material to enemy countries, the burning of stocks of raw materials and finished goods, and the depriving of large industrial centers of electric power, fuel and food. Special agents, who will be placed at your disposal, will supply you with the necessary means for effecting explosions and fires, as well as with a list of people in the country under your supervision who are willing to undertake the task of destruction. (Signed) DR. E. FISCHER. Shortly after the establishment of the German employment bureau, Ambassador Dumba sent the following communication to the Austrian Foreign Office: It is my impression that we can disorganize and hold up for months, if not entirely prevent, the manufacture of munitions in Bethlehem and the Middle West, which, in the opinion of the German military attaché, is of importance and amply outweighs the comparatively small expenditure of money involved.
