I remembered what Nordenholt had said to me some weeks earlier: “I shall deal with them—and I shall do it by the hand of their own fellows.”
So you can understand the roaring tide of industry which mounted day by day in the Area. This sudden stroke had done more than anything else to convince the people of the seriousness of the situation. Ten thousand men had been condemned and had vanished on an instant—Nordenholt made no secret of the number; and the remainder realised that things must indeed be grave when a step of this kind had been necessary. He had given no time for amendment: condemnation had been followed by the execution of the sentence: and it was they themselves who had pronounced the decree. They could not lay it upon his shoulders. And the veil of mystery which enwrapped the fate of the convicted ones had its value in more than one direction. Had Nordenholt caused them to be shot, public sympathy would have been aroused. But this impenetrable secrecy baffled speculation and prevented men from forming any concrete picture which might arouse compassion.
Choosing his moment, Nordenholt announced that, in future, the factories would be run continuously, shift after shift, throughout the twenty-four hours. For a time he called a halt to the newspaper campaign for increased output. He would need this form of publicity later; and he did not wish it to become staled by constant repetition.
For the present he was satisfied. Everything was now in train and he was into his stride all along the line. At last statistics were accumulating which would enable him to gauge exactly how the machinery was running; and he held his hand until a balance-sheet could be drawn with accuracy.
At this point in my narrative I am trying to produce a conspectus of the Nitrogen Area as it was during that period in its career. I leave to the imagination of my readers the task of picturing that gigantic concentration of human effort: the eternal smoke-cloud from a thousand chimney-stalks lying ever between us and the sun; the murky twilight of the streets at noon; the whir of dynamos and the roar of the great electric arcs; the unintermittent thunder of trains pouring coal into the city; and, above all, the half-naked figures in the factories, toiling, toiling, shift after shift in one incessant strain through the four-and-twenty hours. No one can ever depict the details of that panorama.
But alongside this vast outpouring of physical energy there lay another world, calm, orderly and almost silent, yet equally important to the end in view: the world of the scientific experts in their laboratories and research stations. To pass from one region to the other was like a transition from pandemonium to a cloister.
Nordenholt had grouped his experts into three main classes, though of course these groups by no means included all the investigators he controlled. It was here that the Nordenholt Gang were strongest, for the path of the scientific man is one which offered the greatest chances to Nordenholt’s scheme for the furthering of youth.
In the first place came the group of chemists and electricians who were engaged upon the improvement of nitrogen fixation methods; and between this section and the factories there was a constant liaison; so that each new plant which was erected might contain the very latest improvements devised by the experts.
The second group contained the bacteriologists, whose task it was to investigate the habits of B. diazotans, to determine whether it could be exterminated in any practical manner and to discover what methods could be employed to prevent its ravaging the new crops when they were obtainable.
Finally, the experts in agriculture overlapped with the chemical group, since many of the questions before them were concerned with the chemistry of the soil. I have already mentioned how the action of B. diazotans disintegrated the upper strata of the land and reduced the soil to a friable material. This formed one of the most troublesome features in the cultivation problem, since the porosity of the ground allowed water to sink through, and thus plants sown in the affected fields were left without any liquid upon which they could draw for sustenance. It was J. F. Hope, I believe, who finally suggested a solution of the matter. His process consisted in mixing colloid minerals such as clays with the soil and thus forming less permeable beds; and the agricultural experts were able to establish the minimum percentages of clay which were required in order to make crops grow.
I have mentioned these points in order to show how much we in the Area depended upon the pure scientists for help. But it must not be supposed that only those lines of scientific investigation capable of immediate application were kept in view by Nordenholt. I learned later, as I shall tell in its proper place, that he had cast further afield than that.
I cannot give details of the work on the scientific side, because I have no intimate acquaintance with them; but I met the results on every hand in the course of my own department’s affairs. From day to day a new machine would be passed for service and put into operation, some fresh catalyst would be sent down for trial on a large scale after having been tested in the laboratory, or there might be a slight variation in the relative quantities of the ingredients in some of our factory processes. There was a constant touch between research and large-scale operations.
In the course of this I used often to have to visit
