intend to have absolute obedience, and shall not hesitate at the most extreme measures to obtain it. They must be drilled until every man is faultlessly perfect in the part he is to play. We may all be pronounced outlaws at any time with a price upon our heads, and therefore, before leaving here, I wish that none be allowed to join the enterprise except those who willingly volunteer for the sake of the cause. The men who are unwilling to volunteer, and yet know too much, must be taken and held _incommunicado_ in some perfectly safe place until such time as I notify you. "I think that is all," he reflected. Then, while the other man watched him curiously, he stepped to the safe, and opening it brought back a small, hardwood box about six inches square. "I have never explained to you, Page," he said, "the exact construction of the instrument that is contained in this box. As you know, there is but one other instrument like this in the world, and that you know is in a safe place. My reason for not taking anybody into my confidence was not from any lack of faith in you or my other trusted associates, but simply in order to be absolutely sure at all times and under all circumstances that I was the only one in possession of this secret." And turning to the fireplace he threw the box with its contents directly on to the burning logs.

The actual mechanical construction of this instrument is so simple," he said, "that I can at any time construct one which will answer all purposes that I may require of it until I see you. I intend to amuse myself on the _Ivernia_ during the crossing constructing a new smaller and more compact instrument, combining with it one of the receivers which you have attuned to your wireless. See that these as well as the following," handing "Specs" a list of electrical supplies, "are put in Black's steamer trunk. And now, let's have a look at those films." He followed this with a tour of inspection of the entire establishment, although the latter was largely perfunctory in character, since he knew that for days everything had been in readiness for his orders, waiting only for his return from Washington; then returning to his quarters, he tumbled into bed to catch a few hours of sleep before again whirling off at a sixty-mile-an-hour gait to board his steamer at the dock. His plans were completed. His men, down to the lowest helper, were fellows of tested experience and education, many of them college graduates, while his "commissioned officers," as he called them,
