The elfin people fill the Tubes just full to overflow.
The grown-ups do not know it; they put the trains to bed
And never guess that magic will drive them in their stead;
All day the goblin drivers were hiding in the dark
(If mortals catch a fairy's eye they take it for a spark).
Elves patter down the subways; they crowd the moving stairs;
From purses full of tiddly-winks they pay the clerk their fares;
A Brownie checks the tickets and says the proper things:
"Come pass along the car there!" "Now, ladies, mind your wings!"
They're never dull like mortals who read and dream and doze;
