Robert Louis Stevenson

My bed is like a little boat;
     Nurse helps me in when I embark;
She girds me in my sailor's coat
     And starts me in the dark.

At night I go on board and say
     Good-night to all my friends on shore;
I shut my eyes and sail away
     And see and hear no more.

And sometimes things to bed I take,
     As prudent sailors have to do;
Perhaps a slice of wedding-cake,
     Perhaps a toy or two.

All night across the dark we steer;
     But when the day returns at last,
Safe in my room beside the pier,
     I find my vessel fast.
