It Is Not Always May  by Henry Wadsworth Longfellow
The sun is bright, - the air is clear,
The darting swallows 
soar and sing.
And from the stately elms I hear
The bluebird prophesying Spring.
So blue you winding river flows,
It seems an 
outlet from the sky,
Where waiting till the west-wind blows,
The freighted clouds at 
anchor lie.
All things are new; - the buds, the leaves,
That 
gild the elm-tree's nodding crest,
And even the nest beneath the eaves;
There are no birds in last year's nest!
All things 
rejoice in youth and love,
The fullness of their first 
delight!
And learn from the soft heavens above
The melting 
tenderness of night.
Maiden, that read'st this simple 
rhyme,
Enjoy thy youth, it will not stay;
Enjoy the 
fragrance of thy 
prime,
For oh, it is not always May!
Enjoy the Spring of Love and Youth,
To some good angel leave the rest;
For Time will teach thee soon the truth,
There are no birds in last year's nest!
