After business hours these men met their subordinates at various rendezvous in the city; the hotels were convenient, the Manhattan was frequently appointed, and the Deutscher Verein at 112 Central Park South was the liveliest ganglion of all the nerve centers of a system of communication which tapped every section of the great community.

Flynn, chief of the United States Secret Service until 1918, who led the hunt of the German spy] In the lesser cities the German consulate served as the nucleus for the organization. That in San Francisco is conspicuous for its activity, for it prosecuted its own warfare on the entire Pacific coast. Wherever it was necessary German sympathizers furnished accommodations for offices and storage room. Headquarters of every character dotted the country from salons to saloons, from skyscrapers to cellars, each an active control in the manipulation of Germany's almost innumerable enterprises. Those enterprises may be best outlined perhaps, by recalling the three phases of warfare which Germany had to pursue. America had shipped foodstuffs and raw materials in enormous quantities for many years to Germany. Dr. Albert must see to it that she continue to do so. The Imperial funds were at his disposal. He had already the requisite contact with American business. But let him also exert his utmost influence upon America to stop supplying the Allies. If he could do it alone, so much the better; if not, he was at liberty to call upon the military and naval attachés. But in any case "food and arms for Germany and none for the Allies" was the economic war-cry. American supplies must be purchased for Germany and shipped through the European neutral nations, running the blockade. If capital proved obstinate and the Allies covered the market, it would be well to remember that labor produced supplies; labor must therefore be prevented from producing or shipping to the Allies. If labor refused to be interfered with, the cargoes should be destroyed. His enormous task would depend, of course, very much upon the turn of affairs diplomatic. The State Department must be kept amicable. The Glad Hand was to be extended to official America, while the Mailed Fist thrashed about in official America's constituencies. Thus also with Congress, through influential lobbying or the pressure of constituents. Count von Bernstorff knew that the shout raised in a far-off state by a few well-rehearsed pacifists, reinforced by a few newspaper comments, would carry loud and clear to Washington. Upon his shoulders rested the entire existence of the German plan, and he spent a highly active and trying thirty months in Washington in an attempt to avoid the inevitable diplomatic rupture.
