Water-lilies という詩です。そのまま「水仙」と訳しています。水仙が水の上で静かに揺られている様子を「水の精」に例えて歌っています。
Water-lilies（水連）
詩：A.A.Milne 曲：ダコーダ
Where the water-lilies go to and fro
Rocking in the ripples of the water
Lazy on a leaf lies
the Lake King’s daughter
And the faint winds shake her
Who will come and take her?
I will! I will! Keep still! Keep still!
Sleeping on a leaf lies
the Lake King’s daughter
Then the wind comes skipping
To the lilies on the water
And the kind winds wake her
Now who will take her?
With a laugh she’s slipping
Through the lilies on the water
Wait! Wait! Too late! Too late!
Only the water-lilies go to and fro
Dipping, dipping
To the ripples of the water
