on the other, be thou well assur'd,
It lower still and lower sinks its bed,
Till in that part it reuniting join,
Where 't is the lot of tyranny to mourn.
There Heav'n's stern justice lays chastising hand
On Attila, who was the scourge of earth,
On Sextus, and on Pyrrhus, and extracts
Tears ever by the seething flood unlock'd
From the Rinieri, of Corneto this,
Pazzo the other nam'd, who fill'd the ways
With violence and war." This said, he turn'd,
And quitting us, alone repass'd the ford.

CANTO XIII

ERE Nessus yet had reach'd the other bank,
We enter'd on a forest, where no track
Of steps had worn a way. Not verdant there
The foliage, but of dusky hue; not light
The boughs and tapering, but with knares deform'd
And matted thick: fruits there were none, but thorns
Instead, with venom fill'd. Less sharp than these,
Less intricate the brakes, wherein abide
Those animals, that hate the cultur'd fields,
Betwixt Corneto and Cecina's stream.

Here the brute Harpies make their nest, the same
Who from the Strophades the Trojan band
Drove with dire boding of their future woe.
Broad are their pennons, of the human form
Their neck and count'nance, arm'd with talons keen
The feet, and the huge belly fledge with wings
These sit and wail on the drear mystic wood.

The kind instructor in these words began:
"Ere farther thou proceed, know thou art now
I' th' second round, and shalt be, till thou come
Upon the horrid sand: look therefore well
Around thee, and such things thou shalt behold,
As would my speech discredit." On all sides
I heard sad plainings breathe, and none could see
From whom they might have issu'd. In amaze
Fast bound I stood. He, as it seem'd, believ'd,
That I had thought so many voices came
From some amid those thickets close conceal'd,
And thus his speech resum'd: "If thou lop off
A single twig from one of those ill plants,
The thought thou hast conceiv'd shall vanish quite."

Thereat a little stretching forth my hand,
From a great wilding gather'd I a branch,
And straight the trunk exclaim'd: "Why pluck'st thou me?"

Then as the dark blood trickled down its side,
These words it added: "Wherefore tear'st me thus?
Is there no touch of mercy in thy breast?
Men once were we, that now are rooted here.
Thy hand might well have spar'd us, had we been
The souls of serpents." As a brand yet green,
That burning at one end from the' other sends
A groaning sound, and hisses with the wind
Tha
