There is a kind of writer pleased with sound,

Whose fustian head with clouds is compassed round,

No reason can disperse them with its light:

Learn then to think ere you pretend to write.

As your idea's clear, or else obscure,

The expression follows perfect or impure:

What we conceive with ease we can express;

Words to the notions flow with readiness.

Observe the language well in all you write,

And swerve not from it in your loftiest flight.
