Professor Chick made that quite clear.

And when one remembers what Professor Chick's own new trade was, one doesn't know whether to laugh or cry.
The discovery of this strange society was a curiously refreshing thing; to realize that there were ten new trades in the world was like looking at the first ship or the first plough.

It made a man feel what he should feel, that he was still in the childhood of the world.

That I should have come at last upon so singular a body was, I may say without vanity, not altogether singular, for I have a mania for belonging to as many societies as possible: I may be said to collect clubs, and I have accumulated a vast and fantastic variety of specimens ever since, in my audacious youth, I collected the Athenaeum.

At some future day, perhaps, I may tell tales of some of the other bodies to which I have belonged.
I will recount the doings of the Dead Man's Shoes Society (that superficially immoral, but darkly justifiable communion); I will explain the curious origin of the Cat and Christian, the name of which has been so shamefully misinterpreted; and the world shall know at last why the Institute of Typewriters coalesced with the Red Tulip League.
