They came to my small laboratory with much eager curiosity. From their manner of making themselves known to me I realized with joy that they were dealing with a stranger. Indeed it was improbable that it should have been otherwise for there were upwards of fifty thousand chemists of my rank in Berlin.
The demonstration went off with a flourish and the committee were greatly impressed. Means were at once taken to alter the gas with which the Stassfurt mines were flooded, but I realized that meant nothing since I believed that my companions had abandoned the enterprise and the secret that had enabled me to invade mines had not been shared with any one in the outer world.
As I anticipated, my revelation was accepted by the Chemical Staff as evidence of profound scientific genius. It followed as a logical matter that I should be promoted to the highest rank of research chemists with the title of Colonel. Because of my youth the more was made of the honour. This promotion entitled me to double my previous salary, to a larger laboratory and larger and better living quarters in a distant part of the city.
My assistant would now be of the rank I had previously been and as Holknecht was not eligible to such promotion I was removed entirely from all previous acquaintances and surroundings and so greatly decreased the chance of discovery of my true identity.

After I had removed to my new quarters I was requested to call at the office of the Chemical Staff to discuss the line of research I should next take up. My adviser in this matter was the venerable Herr von Uhl, a white haired old patriarch whose jacket was a mass of decorations. The insignia on the left breast indicating the achievements in chemical science were already familiar to me, but those on the right breast were strange.
Perhaps I stared at them a little, for the old man, noting my interest, remarked proudly, "Yes, I have contributed much glory to the race and our group,--one hundred and forty-seven children,--one hundred and four of them sons, fifty-eight already of a captain's rank, and twenty-nine of them colonels--my children of the second and third generation number above two thousand. Only three men living in Berlin have more total descendants--and I am but seventy-eight years of age. If I live to be ninety I shall break all records of the Eugenic Office. It all comes of good breeding and good work. I won my paternity right, when I was but twenty-eight, just about your age. If you pass the physical test, perhaps you can duplicate my record. For this early promotion you have won qualifies you mentally."
Astonished and alarmed beyond measure I could find no reply and sat staring dumbly, while Herr von Uhl, beginning to speak of chemical matters, inquired if I had any preference as to the problem I should now take up. Incapable of any clear thinking I could only ask if he had any to suggest.
Immediately the old man's face brightened. "A man of your genius," he said, "should be permitted to try his brain with the greatest problems on which the life of Germany depends. The Staff discussed this and has assigned you to original research for the finding of a better method of the extraction of protium from the ore. To work on this assignment you must of necessity share grave secrets, which, should they be disclosed, might create profound fears, but your professional honour is a sufficient guarantee of secrecy. In this research you will compete with some of the most distinguished chemists in Berlin. If you should be successful you will be decorated by His Majesty and you will receive a liberal pension commensurate with the value of your discovery."
I was profoundly impressed. Evidently I had stumbled upon something of vital importance, the real nature of which I did not in the least comprehend, and happily was not supposed to. The interview was ended by my being entrusted with voluminous unpublished documents which I was told to take home and study. Two armed men were ordered to accompany me and to stand alternate guard outside my apartment while I had the documents in my possession.
