Robert Crawford - Madrigal.

When morn is wandering on the seas,
And birds are singing in the trees,
And all the time is flushed with flowers,
And youth is in these hearts of ours —
How sweet then 'tis to love!
How sweet then 'tis to prove
How much a man can be to a maid
In the greenwood shade!

Robert Crawford
