e _ends the Song,
That like a wounded Snake, drags its slow Length along_.

And afterwards,

Tis not enough no Harshness gives Offence,
The Sound must seem an Eccho to the Sense.
Soft is the Strain when Zephyr gently blows,
And the smooth Stream in smoother Numbers flows;
But when loud Surges lash the sounding Shore,
The hoarse rough Verse shou'd like the Torrent roar.
When Ajax strives some Rocks vast Weight to throw,
The Line too labours, and the Words move slow;
Not so, when swift Camilla scours the Plain,
Flies o'er th' unbending Corn, and skims along the Main.

The beautiful Distich upon _Ajax_ in the foregoing Lines, puts me in
mind of a Description in _Homer's_ Odyssey, which none of the Criticks
have taken notice of. [3] It is where _Sisyphus_ is represented lifting
his Stone up the Hill, which is no sooner carried to the top of it, but
it immediately tumbles to the Bottom. This double Motion of the Stone is
admirably described in the Numbers of these Verses; As in the four first
it is heaved up by several _Spondees_ intermixed with proper Breathing
places, and at last trundles down in a continual Line of _Dactyls_.

[Greek: Kai maen Sisyphon eiseidon, krater alge echonta,
Laan Bastazonta pelorion amphoteraesin.
Aetoi ho men skaeriptomenos chersin te posin te,
Laan ano otheske poti lophon, all hote melloi
Akron hyperbaleein, tot apostrepsaske krataiis,
Autis epeita pedonde kylindeto laas anaidaes.]

It would be endless to quote Verses out of _Virgil_ which have this
particular Kind of Beauty in the Numbers; but I may take an Occasion in
a future Paper to shew several of them which have escaped the
Observation of others.

I cannot conclude this Paper without taking notice that we have three
Poems in our Tongue, which are of the same Nature, and each of them a
Master-Piece in its Kind; the Essay on Translated Verse [4], the Essay
on the Art of Poetry [5], and the Essay upon Criticism.

[Footnote 2: At the time when this paper was written Pope was in his
twenty-fourth year. He wrote to express his gratitude to Addison and
also to Steele. In his letter to Addison he said,

Though it be the highest satisfaction to find myself commended by a
Writer whom all the world commends, yet I am not more obliged to you
for that than for your candour and frankness in acquainting me with
the error I have been guilty of in speaking too fr
