A Child's Garden of Verses

A 1001 CBYMRBYGU.
I'm obligated to read all of Stevenson's oeuvre. My school is named after this man.
This book contains a variety of short poems for children written by RLS himself. The poems range from the proscriptive:
“A child should always say what's true
And speak when he is spoken to,
And behave mannerly at table;
At least as far as he is able.”

To:
“The world is so full of a number of things,
I'm sure we should all be as happy as kings.”
