English literal translation:

Where a little stream flows slowly
and May sows herbs,
a field daisy grew
and a grove rustled above her.

"It's so bleak in this grove,
that I'm horrified,
the fledgelings are too high,
and loneliness is bad for me."

Then a scout goes slowly:
"O Daisy, hello,
your charm impresses me,
do you want to be mine or not?"

The daisy agreed
And they went into dark forest,
But the scout was such a scatterbrain,
that he got into nettles.

And she, she, she,
what has to do, poor thing?
Leaned over the scatterbrain
and laughs: "Ha ha!"
