"That is none of my affair," said the labour psychologist; "these chemical matters I do not comprehend. But I advise against these transfers, for our workers are already in a furor about the change of operations in the work." "But," I protested, "the new operations are easier than the old; besides we can cut down the speed of operations, which ought to help you take care of these surplus men." "Pardon, Herr Chief," returned the elderly labour psychologist, "you are a great chemist, a very great chemist, for your invention has upset the labour operation more than has anything that ever happened in my long experience, but I fear you do not realize how necessary it is to go slow in these matters. You ask men who have always opened a faucet from left to right to now open one that moves in a vertical plane. Here, I will show you; move your arm so; do you not see that it takes different muscles?" "Yes, of course, but what of it? The solution flows faster and the operation is easier." "It is easy for you to say that; for you or me it would make no difference since our muscles have all been developed indiscriminately." "But what are your labour gymnasiums for, if not to develop all muscles?" "Now do not misunderstand me. I serve as an interpreter between the minds of the workers and your mind as Director of the Works. As for the muscles developed in the gymnasium, those were developed for sport and not for labour. But that is not the worst of it; you have designed the new benches so low that the mixers must stoop at their work. It is very painful." "Good God," I cried, "what became of the stools? The mixers are to sit down--I ordered two thousand stools." "That I know, Herr Chief, but the equipment expert consulted me about the matter and I countermanded the order. It would never do. I did not consult you, it is true, but that was merely a kindness. I did not wish to expose your lack of knowledge, if I may call it such." "Call it what you please," I snapped, for at the time I thought my labour psychologist was a fool, "but get those stools, immediately." "But it would never do." "Why not?" "Because these men have always stood at their work." "But why can they not sit down now?" "Because they never have sat down." "Do they not sit down to eat?" "Yes, but not to work. It is very different. You do not understand the psychic immobility of labour. Habits grow stronger as the mentality is simplified. I have heard that there are animals in the zoological garden that still perform useless operations that their remote ancestors required in their jungle life." "Then do you infer that these men who must stand at their work inherited the idea from their ancestors?"
