"And how," I asked eagerly, "do the ore-bringing vessels get from Berlin to the sea?"

My visitors glanced at each other significantly. "Do you not know that?" exclaimed Zimmern. "We had supposed you would have been told when you were assigned to the protium research."

By way of answer I explained that I knew the source of the ore but not the route of its coming.

"All such knowledge is suppressed in books," commented Hellar; "we older men know of this by word of mouth from the days when the submarine tunnel was completed to the sea, but you are younger. Unless this was told you at the time you were assigned the work it is not to be expected that you would know."

I questioned Hellar and Zimmern closely but found that all they knew was that a submarine tunnel did exist leading from Berlin somewhere into the open sea; but its exact location they did not know. Again I pressed my question as to what I could do with the power of my secret and they could only repeat that they staked their hopes on getting word to the outer world by way of submarines.

Much as I might admire the strength of character that would lead men to rebel against the only life they knew because they sensed that it was hopeless, I now found myself a little exasperated at the vagueness of their plans. Yet I had none better. To defy the Emperor would merely be to risk my life and the possible loss of my knowledge to the world. Perhaps after all the older heads were wiser than my own rebellious spirit; and so, without making any more definite plans, I ended the interview with a promise to let them know of the outcome of the demonstration.

Returning once more to my work I finished my preparations and sent word to the Chemical Staff that all was ready. They came with solemn faces. The laboratory was locked and guards were posted. The place was examined thoroughly, the apparatus was studied in detail. All my ingredients were tested for the presence of extracted protium, lest I be trying to "salt the mine." But happily for me they accepted my statement as to their chemical nature in other respects. Then when all had been approved the test lot of ore was run. It took us thirty hours to run the extraction and sample and weigh and test the product. But everything went through exactly as I had planned.

With solemn faces the Chemical Staff unanimously declared that the problem had been solved and marvelled that the solution should come from the brain of so young a man. And so I received their adulation and worship, for I could not give credit to the chemists of the world outside to whom I was really indebted for my seeming miraculous genius. Telling me to take my rest and prepare myself for an audience with His Majesty three days later, the Chemical Staff departed, carrying, with guarded secrecy, my false formulas.

Exultant and happy I left the laboratory. I had not slept for forty hours and scarcely half my regular allotment for many weeks. And yet I was not sleepy now but awake and excited. I had won a great victory, and I wanted to rejoice and share my conquest with sympathetic ears. I could go to Zimmern, but instead I turned my steps toward the elevator and, alighting on the Level of the Free Women, I went straightway to Marguerite's apartment.
