"Your Excellency:" the letter ran in German, "Dr. Albert and myself today took up your suggestion of an invasion of Canada with Count Von Bernstorff. While he believes that the enterprise would be an exceedingly dangerous one and that we should use every precaution to prevent the Secret Service from charging us with any part in it, should it fail, there is reason to believe that such an enterprise would meet with a great measure of success. "I reported to him that our plan included the raiding of all important points of Canada possessing military stores, such as Windsor, Montreal, Winnipeg, Regina, Port Hope and other centers, the demoralization of which would mean great delay in the sending overseas of large expeditionary forces on the part of Great Britain. "B. asked what had been done and I told him that arms already had been stored in six sections, assembling at Silver Creek, Mich., there to seize the Welland Canal, Wind Mill Point, Mich., Wilson, N.Y., adjacent to Port Hope, Can., Watertown, N.Y., near Kingston, Can., Detroit, near Windsor, Can., Cornwall, N.Y., from which easy possession can be made of Ottawa, Can., and at Exeter. "It is at Exeter, as I explained to B., that everything must be done now, inasmuch as arms and reservists are available for all the other stations. However, as you told me to explain, I showed B. that all efforts must now be centered on Exeter, and that Von Lertz and Madam Stephen should leave at once to represent us in the final work which will immediately precede the invasion. "In this connection, might I suggest to you that this be done at once, as more than 100,000 reservists throughout the United States will shortly receive their orders to move toward the border in as inconspicuous a manner as possible, and that everything should be awaiting them when they arrive. Otherwise, we fail. Dr. Albert and myself will attend to the shipment of arms by the usual method. "B.E." Efficiency again--efficiency in the shape of another written report from one office to another, in the stolid, plodding desire of Imperial Germany to see that every step of its murderous progress was arranged for and made clear to those in whose hands the trend of events lay. This time it had made clear one of its plots to Dixie Mason of the Secret Service! Across the top of the letter, in Von Papen's scrawling hand, had been written: "Von Lertz and Stephan ... 10:20, N.Y.C." "N.Y.C." New York Central, of course, and they were leaving at 10:20! Dixie glanced at her watch. It was a quarter after nine. She had wondered at the extreme earliness of Von Lertz's visit. Now she knew. He must catch that train. There were things she must do, too. Suddenly she caught at the window frame and gave a little moan. Von Lertz looked up in time to see her slide limply to the floor in a faint. He rushed to her and picking up her unconscious form laid her on the long leather lounge that stood at one side of the room.
