Heav'n first taught letters for some wretch's aid,
Some banish'd lover, or some captive maid;
They live, they speak, they breathe what love inspires,
Warm from the soul, and faithful to its fires,
The virgin's wish without her fears impart,
Excuse the blush, and pour out all the heart,
Speed the soft intercourse from soul to soul,
And waft a sigh from Indus to the Pole.
