After exhausting the rather barren sport of walking about the monotonous streets of the four professional levels I took a more exciting trip down into the lower levels of the city where the vast mechanical industries held sway. I did not know how much freedom might be allowed me, but I reasoned that I would be out of my supposed normal environment and hence my ignorance would be more excusable and in less danger of betraying me.

Alighting from the elevator, I hurried along past endless rows of heavy columns. I peered into the workrooms, which had no enclosing walls, and discovered with some misgiving that I seemed to have come upon a race of giants. The men at the machines were great hulking fellows with thick, heavy muscles such as one would expect to see in a professional wrestler or weight-lifter. I paused and tried to gauge the size of these men: I decided that they were not giants for I had seen taller men in the outer world. Two officials of some sort, distinguishable by finer garb, walking among them, appeared to be men of average size, and the tops of their heads came about to the workers' chins. That there should be such men among the Germans was not unbelievable, but the strange thing was that there should be so many of them, and that they should be so uniformly large, for there was not a workman in the whole vast factory floor that did not over-top the officials by at least half a head.

"Of course," I reasoned, "this is part of German efficiency";--for the men were feeding large plates through stamping mills--"they have selected all the large men for this heavy work." Then as I continued to gaze it occurred to me that this bright metal these Samsons were handling was aluminum!

I went on and came to a different work hall where men were tending wire winding machinery, making the coils for some light electrical instruments. It was work that girls could easily have done, yet these men were nearly, if not quite, as hulking as their mates in the stamping mill. To select such men for light-fingered work was not efficiency but stupidity,--and then it came to me that I had also thought the soldiers I had seen in the hospital to be men picked for size, and that in a normal population there could not be such an abundance of men of abnormal size. The meaning of it all began to clear in my mind--the pedigree in my own identification folder with the numerous fraternity, the system of social castes which my atlas had revealed, the inexplicable and unnatural proportion of the sexes. These gigantic men were not the mere pick from individual variation in the species, but a distinct breed within a race wherein the laws of nature, that had kept men of equal stature for countless centuries, even as wild animals were equal, had been replaced by the laws of scientific breeding. These heavy and ponderous labourers were the Percherons and Clydesdales of a domesticated and scientifically bred human species. The soldiers, somewhat less bulky and more active, were, no doubt, another distinct breed. The professional classes which had seemed quite normal in physical appearance--were they bred for mental rather than physical qualities? Otherwise why the pedigree, why the rigid castes, the isolation of women? I shuddered as the whole logical, inevitable explanation unfolded. It was uncanny, unearthly, yet perfectly scientific; a thing the world had speculated about for centuries, a thing that every school boy knew could be done, and yet which I, facing the fact that it had been done, could only believe by a strained effort at scientific coolness.

I walked on and on, absorbed, overwhelmed by these assaulting, unbelievable conclusions, yet on either side as I walked was the ever present evidence of the reality of these seemingly wild fancies. There were miles upon miles of these endless workrooms and everywhere the same gross breed of great blond beasts.

The endless shops of Berlin's industrial level were very like those elsewhere in the world, except that they were more vast, more concentrated, and the work more speeded up by super-machines and excessive specialization. Millions upon millions of huge, drab-clad, stolid-faced workmen stood at their posts of duty, performing over and over again their routine movements as the material of their labors shuttled by in endless streams.

Occasionally among the workmen I saw the uniforms of the petty officers who acted as foremen, and still more rarely the administrative offices, where, enclosed in glass panelled rooms, higher officials in more bespangled uniforms poured over charts and plans.

In all this colossal business there was everywhere the atmosphere of perfect order, perfect system, perfect discipline. Go as I might among the electrical works, among the vast factories of chemicals and goods, the lighter labor of the textile mills, or the heavier, noisier business of the mineral works and machine shops the same system of colossal coordinate mechanism of production throbbed ceaselessly. Materials flowed in endless streams, feeding electric furnaces, mills, machines; passing out to packing tables and thence to vast store rooms. Industry here seemed endless and perfect. The bovine humanity fitted to the machinery as the ox to the treadmill. Everywhere was the ceaseless throbbing of the machine. Of the human variation and the free action of man in labour, there was no evidence, and no opportunity for its existence.

Turning from the mere monotonous endlessness of the workshops I made my way to the levels above where the workers lived in those hours when they ceased to be a part of the industrial mechanism of production; and everywhere were drab-coloured men for these shifts of labour were arranged so that no space at any time was wholly idle. I now passed by miles of sleeping dormitories, and other miles of gymnasiums, picture theatres and gaming tables, and, strikingly incongruous with the atmosphere of the place, huge assembly rooms which were labelled "Free Speech Halls." I started to enter one of these, where some kind of a meeting was in progress, but I was thrust back by a great fellow who grinned foolishly and said: "Pardon, Herr Captain, it is forbidden you."

Through half-darkened streets, I again passed by the bunk-shelved sleeping chambers with their cavernous aisles walled with orderly rows of lockers. Again I came to other barracks where the men were not yet asleep but were straggling in and sitting about on the lowest bunks of these sterile makeshift homes.
