The poem
A POOL was once congeal'd with frost; The frogs, in its deep waters lost,
No longer dared to croak or spring; But promised, being half asleep, If suffer'd to the air to creep,
As very nightingales to sing.
A thaw dissolved the ice so strong,-- They proudly steer'd themselves along, When landed, squatted on the shore, And croak'd as loudly as before.
1821.*
