Some from the rocks cast themselves down headlong.

"And many more: but it is enough to instance in a few. The thing is,
that the disposition of words and numbers should be such, as that,
out of the order and sound of them, the things themselves may be
represented. This the Greeks were not so accurate as to bind themselves
to; neither have our English poets observed it, for aught I can find.
The Latins (qui musas colunt severiores) sometimes did it; and their
prince, Virgil, always, in whom the examples are innumerable, and taken
notice of by all judicious men, so that it is superfluous to collect
them."

I know not whether he has, in many of these instances, attained the
representation or resemblance that he purposes. Verse can imitate only
sound and motion. A _boundless_ verse, a _headlong_ verse, and a verse
of _brass_, or of _strong brass_, seem to comprise very incongruous
and unsociable ideas. What there is peculiar in the sound of the line
expressing _loose care_, I cannot discover; nor why the _pine_ is
_taller_ in an alexandrine than in ten syllables.

But, not to defraud him of his due praise, he has given one example of
representative versification, which, perhaps, no other English line can
equal:

Begin, be bold, and venture to be wise:
He, who defers this work from day to day,
Does on a river's bank expecting stay
Till the whole stream that stopp'd him shall be gone,
_Which runs, and, as it runs, for ever shall run on_.
