I wind about, and in and out,
With here a blossom sailing,
And here and there a lusty trout,
And here and there a grayling.

Paraphrase: The brook goes on flowing in a zig-zag way sometimes shrinking and sometimes expanding. We can find a blossom sailing over its surface. Here and there we can find a big and fat trout and at other places, we can find a grayling swimming in and out of it.
