Spring Song by Robert Louis Stevenson

THE air was full of sun and birds,
The fresh air sparkled clearly.
Remembrance wakened in my heart
And I knew I loved her dearly.

The fallows and the leafless trees
And all my spirit tingled.
My earliest thought of love, and Spring's
First puff of perfume mingled.

In my still heart the thoughts awoke,
Came lone by lone together -
Say, birds and Sun and Spring, is Love
A mere affair of weather?
