You have heard, let us say, of the German parade step, sometimes laughed at as the "goose step" in England and at home. I was lunching the other day with an American military observer, and he spoke of the parade step and the effect it had on him. "Did you ever see it?" he demanded. "Have you any idea of the moral effect of that step? You see those men marching by, every muscle in their bodies taut and tingling as steel wire, every eye on the Emperor, and when they bring those feet down--bing! bang!-- the physical fitness it stands for, the unity, determination--why, it's the whole German idea--nothing can stop them!"
The parade step in Japan is practically the German goose-step, and the arms are brought to horizontal position in front at each swing. This may, to the superficial observer, seem absurd, but it conveys a strong sense of momentum and force, and I fully believe it has a sort of hypnotic effect on the soldiers, making them feel stronger and more consequential. It is by no manner of means to be laughed at, that I am certain of.
While they were in difficulties, there was a pit pat paddle pat! and the three Puddle-Ducks came along the hard high road, marching one behind the other and doing the goose step—pit pat paddle pat! pit pat waddle pat!
However, the English term wasn't at first applied to the stiff-legged parade march but to a form of drill in which recruits were taught to stand alternately on one leg and swing the other back and forwards, keeping the knee straight.
