I wandered lonely as a cloud
That floats on high o’er vales and hills,
When all at once I saw a crowd,

A host, of golden daffodils;
Beside the lake, beneath the trees,
Fluttering and dancing in the breeze.
Continuous as the stars that shineAnd twinkle on the milky way,
They stretched in never-ending lineAlong the margin of a bay:
Ten thousand saw I at a glance,
Tossing their heads in sprightly dance.
