I then came into a district of mess halls where a meal was being served. Here again was absolute economy and perfect system. The men dined at endless tables and their food like the material for their labours, was served to the workers by the highly efficient device of an endless moving belt that rolled up out of a slot in the floor at the end of the table after the manner of the chained steps of an escalator.
From the moving belts the men took their portions, and, as they finished eating, they cleared away by setting the empty dishes back upon the moving belt. The sight fascinated me, because of the adaptation of this mechanical principle to so strange a use, for the principle is old and, as every engineer knows, was instrumental in founding the house of Detroit Vehicle Kings that once dominated the industrial world. The founder of that illustrious line gave the poorest citizen a motor car and disrupted the wage system of his day by paying his men double the standard wage, yet he failed to realize the full possibilities of efficiency for he permitted his men to eat at round tables and be served by women! Truly we of the free world very narrowly escaped the fetish of efficiency which finally completely enslaved the Germans.
Each of the long tables of this Berlin dining hall, the ends of which faced me, was fenced off from its neighbours. At the entrance gates were signs which read "2600 Calories," "2800 Calories," "3000 Calories"--I followed down the line to the sign which read "Maximum Diet, 4000 Calories." The next one read, "Minimum Diet 2000 Calories," and thence the series was repeated. Farther on I saw that men were assembling before such gates in lines, for the meal there had not begun. Moving to the other side of the street I walked by the lines which curved out and swung down the street. Those before the sign of "Minimum Diet" were not quite so tall as the average, although obviously of the same breed. But they were all gaunt, many of them drooped and old, relatively the inferior specimens and their faces bore a cowering look of fear and shame, of men sullen and dull, beaten in life's battle. Following down the line and noting the improvement in physique as I passed on, I came to the farthest group just as they had begun to pass into the hall. These men, entering the gate labelled "Maximum Diet, 4000 Calories," were obviously the pick of the breed, middle-aged, powerful, Herculean,--and yet not exactly Herculean either, for many of them were overfull of waistline, men better fed than is absolutely essential to physical fitness. Evidently a different principle was at work here than the strict economy of food that required the periodic weighing of the professional classes.
Turning back I now encountered men coming out of the dining hall in which I had first witnessed the meal in progress. I wanted to ask questions and yet was a little afraid. But these big fellows were seemingly quite respectful; except when I started to enter the Free Speech Hall, they had humbly made way for me. Emboldened by their deference I now approached a man whom I had seen come out of a "3800 Calories" gate, and who had crossed the street and stood there picking his teeth with his finger nail.
He ceased this operation as I approached and was about to step aside. But I paused and smiled at him, much, I fear, as one smiles at a dog of unknown disposition, for I could hardly feel that this ungainly creature was exactly human. He smiled back and stood waiting.
"Perhaps, I stammered," you will tell me about your system of eating; it seems very interesting."
"I eat thirty-eight," he grinned, "pretty good, yes? I am twenty-five years old and not so tall either."
I eyed him up--my eyes came just to the top button of his jacket.
"I began thirty," continued the workman, "I came up one almost every year, one year I came up two at once. Pretty good, yes? One more to come."
"What then?" I asked.
