Louisa May Alcott - Hello! Hello!

'Hello! hello!
Come down below,--
It's lovely and cool
Out here in the pool;
On a lily-pad float
For a nice green boat.
Here we sit and sing
In a pleasant ring;
Or leap frog play,
In the jolliest way.
Our games have begun,
Come join in the fun.'

Louisa May Alcott
