Analysis of A Thought For Spring.

I am happier for the Spring;
For my heart is like a bird
That has many songs to sing,
But whose voice is never heard
Till the happy year is caroling
To the daisies on the sward.

I'd be happier for the Spring,
Though my heart had grown so old
Like a crone 'twould sit and sing
Its shrill runes of wintry cold;
For I'd know the year was caroling
To the daisies on the wold.
