Thine is the gentle day of love,
When youths and virgins try their fate;
When, deep retiring to the grove,
Each feathered songster weds his mate.
With tempered beams the skies are bright,
Earth decks in smiles her pleasing face;
Such is the day that gave thee light,
And speaks as such thy every grace.
James Thomson
