Lines Written in Early Spring

I heard a thousand blended notes
While in a grove I sate reclined,
In that sweet mood when pleasant thoughts
Bring sad thoughts to the mind.
To her fair works did Nature link
The human soul that through me ran,
And much it grieved my heart to think
What man has made of man.
Through primrose tufts,in that green bower,
The periwinkle trailed its wreaths;
And 'tis my faith that every flower
Enjoy the air it breathes.
The birds around me hoped and played;
Their thought:I cannot measure:—
But the least motion which they made
It seemed a thrill of pleasure.
The budding twigs spread out their fan
To catch the breezy air;
And I must think,do all I can,
That there was pleasure there.
If this belief from heaven be sent,
If such be Nature's holy plan,
Have I not reason to lament
What man has made of man?
