What Bertie Saw in the Flowers by L.G.R. Fairy poem

Buttercup! Buttercup!
Hold your shining clusters up!
In each little house of gold,
What is this that I behold?
Twenty soldiers, straight and slim,
Golden-helmeted and prim.
All day long so still they stand,
Never turning head or hand;
No one guesses where they stray
In the moonlight nights of May.
When the fairies are abroad,
These small men keep watch and ward;
Round the fairy ring they pace
All night long, to guard the place;
But when morning comes again,
Back are all the little men.
