Besides, the clouds take in from time to time
Much moisture risen from the broad marine,--
Whilst the winds bear them o'er the mighty sea,
Like hanging fleeces of white wool. Thuswise,
Even from all rivers is there lifted up
Moisture into the clouds. And when therein
The seeds of water so many in many ways
Have come together, augmented from all sides,
The close-jammed clouds then struggle to discharge
Their rain-storms for a two-fold reason: lo,
The wind's force crowds them, and the very excess
Of storm-clouds (massed in a vaster throng)
Giveth an urge and pressure from above
And makes the rains out-pour. Besides when, too,
The clouds are winnowed by the winds, or scattered
Smitten on top by heat of sun, they send
Their rainy moisture, and distil their drops,
Even as the wax, by fiery warmth on top,
Wasteth and liquefies abundantly.
But comes the violence of the bigger rains
When violently the clouds are weighted down
Both by their cumulated mass and by
The onset of the wind. And rains are wont
To endure awhile and to abide for long,
When many seeds of waters are aroused,
And clouds on clouds and racks on racks outstream
In piled layers and are borne along
From every quarter, and when all the earth
Smoking exhales her moisture. At such a time
When sun with beams amid the tempest-murk
Hath shone against the showers of black rains,
Then in the swart clouds there emerges bright
The radiance of the bow.

And as to things
Not mentioned here which of themselves do grow
Or of themselves are gendered, and all things
Which in the clouds condense to being--all,
Snow and the winds, hail and the hoar-frosts chill,
And freezing, mighty force--of lakes and pools
The mighty hardener, and mighty check
Which in the winter curbeth everywhere
The rivers as they go--'tis easy still,
Soon to discover and with mind to see
How they all happen, whereby gendered,
When once thou well hast understood just what
Functions have been vouchsafed from of old
Unto the procreant atoms of the world.
Now come, and what the law of earthquakes is
Hearken, and first of all take care to know
That the under-earth, like to the earth around us,
Is full of windy caverns all about;
And many a pool and many a grim abyss
She bears within her bosom, ay, and cliffs
And jagged scarps; and many a river, hid
Beneath her chine, rolls rapidly along
Its billows and plunging boulders. For clear fact
Requires that earth must be in every part
Alike in constitution. Therefore, earth,
With these things underneath affixed and set,
Trembleth above, jarred by big down-tumblings,
When time hath undermined the huge caves,
The subterranean. Yea, whole mountains fall,
And instantly from spot of that big jar
There quiver the tremors far and wide abroad.
And with good reason: since houses on the street
Begin to quake throughout, when jarred by a cart
Of no large weight; and, too, the furniture
Within the house up-bounds, when a paving-block
Gives either iron rim of the wheels a jolt.
It happens, too, when some prodigious bulk
Of age-worn soil is rolled from mountain slopes
Into tremendous pools of water dark,
That the reeling land itself is rocked about
By the water's undulations; as a basin
Sometimes won't come to rest until the fluid
Within it ceases to be rocked about
In random undulations.

And besides,
When subterranean winds, up-gathered there
In the hollow deeps, bulk forward from one spot,
And press with the big urge of mighty powers
Against the lofty grottos, then the earth
Bulks to that quarter whither push amain
The headlong winds.
Then all the builded houses
Above ground--and the more, the higher up-reared
Unto the sky--lean ominously, careening
Into the same direction; and the beams,
Wrenched forward, over-hang, ready to go.
Yet dread men to believe that there awaits
The nature of the mighty world a time
Of doom and cataclysm, albeit they see
So great a bulk of lands to bulge and break!
And lest the winds blew back again, no force
Could rein things in nor hold from sure career
On to disaster. But now because those winds
Blow back and forth in alternation strong,
And, so to say, rallying charge again,
And then repulsed retreat, on this account
Earth oftener threatens than she brings to pass
Collapses dire. For to one side she leans,
Then back she sways; and after tottering
Forward, recovers then her seats of poise.
Thus, this is why whole houses rock, the roofs
More than the middle stories, middle more
Than lowest, and the lowest least of all.

Arises, too, this same great earth-quaking,
When wind and some prodigious force of air,
Collected from without or down within
The old telluric deeps, have hurled themselves
Amain into those caverns sub-terrene,
And there at first tumultuously chafe
Among the vasty grottos, borne about
In mad rotations, till their lashed force
Aroused out-bursts abroad, and then and there,
Riving the deep earth, makes a mighty chasm--
What once in Syrian Sidon did befall,
And once in Peloponnesian Aegium,
Twain cities which such out-break of wild air
And earth's convulsion, following hard upon,
O'erthrew of old. And many a walled town,
Besides, hath fall'n by such omnipotent
Convulsions on the land, and in the sea
Engulfed hath sunken many a city down
With all its populace. But if, indeed,
They burst not forth, yet is the very rush
Of the wild air and fury-force of wind
Then dissipated, like an ague-fit,
Through the innumerable pores of earth,
To set her all a-shake--even as a chill,
When it hath gone into our marrow-bones,
Sets us convulsively, despite ourselves,
A-shivering and a-shaking. Therefore, men
With two-fold terror bustle in alarm
Through cities to and fro: they fear the roofs
Above the head; and underfoot they dread
The caverns, lest the nature of the earth
Suddenly rend them open, and she gape,
Herself asunder, with tremendous maw,
And, all confounded, seek to chock it full
With her own ruins. Let men, then, go on
Feigning at will that heaven and earth shall be
Inviolable, entrusted evermore
To an eternal weal: and yet at times
The very force of danger here at hand
Prods them on some side with this goad of fear--
This among others--that the earth, withdrawn
Abruptly from under their feet, be hurried down,
Down into the abyss, and the Sum-of-Things
Be following after, utterly fordone,
Till be but wrack and wreckage of a world.

EXTRAORDINARY AND PARADOXICAL TELLURIC
PHENOMENA


In chief, men marvel nature renders not
Bigger and bigger the bulk of ocean, since
So vast the down-rush of the waters be,
And every river out of every realm
Cometh thereto; and add the random rains
And flying tempests, which spatter every sea
And every land bedew; add their own springs:
Yet all of these unto the ocean's sum
Shall be but as the increase of a drop.
Wherefore 'tis less a marvel that the sea,
The mighty ocean, increaseth not. Besides,
Sun with his heat draws off a mighty part:
Yea, we behold that sun with burning beams
To dry our garments dripping all with wet;
And many a sea, and far out-spread beneath,
Do we behold. Therefore, however slight
The portion of wet that sun on any spot
Culls from the level main, he still will take
From off the waves in such a wide expanse
Abundantly. Then, further, also winds,
Sweeping the level waters, can bear off
A mighty part of wet, since we behold
Oft in a single night the highways dried
By winds, and soft mud crusted o'er at dawn.
