I keep six honest serving-men: (They taught me all I knew) Their names are What and Where and When And How… — Rudyard Kipling

I am the cat who walks by himself, and all places are alike to me.

When the cabin port-holes are dark and green

Because of the seas outside;

When the ship goes wop (with a wiggle between)

And the steward falls into the soup-tureen,

And the trunks begin to slide;

When Nursey lies on the floor in a heap,

And Mummy tells you to let her sleep,

And you aren't waked or washed or dressed,

Why, then you will know (if you haven't guessed)

You're ‘Fifty North and Forty West!'
