The Germans unwisely backed their engine.

"We have a city of light.

But instead of lying ahead it lies direct behind us.

So reverse engines.

Reverse engines, and away, away to our city, where the sterilized milk is delivered by noiseless aeroplanes, _at the very precise minute when our great doctors of the Fatherland have diagnosed that it is good for you_: where the teeth are not only so painlessly planted that they grow like living rock, but where their composition is such that the friction of eating stimulates the cells of the jaw-bone and develops the _superman strength of will which makes us gods_: and where not only is twilight sleep serene, but into the sleeper are inculcated the most useful and instructive dreams, calculated to perfect the character of the young citizen at this crucial period, and to enlighten permanently the mind of the happy mother, with regard to her new duties towards her child and towards our great Fatherland--" Here you see we are, on the railway, with New Jerusalem ahead, and New Jerusalem away behind us.
