Now for the native gifts of various soils,
What powers hath each, what hue, what natural bent
For yielding increase. First your stubborn lands
And churlish hill-sides, where are thorny fields
Of meagre marl and gravel, these delight
In long-lived olive-groves to Pallas dear.
Take for a sign the plenteous growth hard by
Of oleaster, and the fields strewn wide
With woodland berries. But a soil that's rich,
In moisture sweet exulting, and the plain
That teems with grasses on its fruitful breast,
Such as full oft in hollow mountain-dell
We view beneath us—from the craggy heights
Streams thither flow with fertilizing mud—
A plain which southward rising feeds the fern
By curved ploughs detested, this one day
Shall yield thee store of vines full strong to gush
In torrents of the wine-god; this shall be
Fruitful of grapes and flowing juice like that
We pour to heaven from bowls of gold, what time
The sleek Etruscan at the altar blows
His ivory pipe, and on the curved dish
We lay the reeking entrails.
If to rear
Cattle delight thee rather, steers, or lambs,
Or goats that kill the tender plants, then seek
Full-fed Tarentum's glades and distant fields,
Or such a plain as luckless Mantua lost
Whose weedy water feeds the snow-white swan:
There nor clear springs nor grass the flocks will fail,
And all the day-long browsing of thy herds
Shall the cool dews of one brief night repair.
Land which the burrowing share shows dark and rich,
With crumbling soil—for this we counterfeit
In ploughing—for corn is goodliest; from no field
More wains thou'lt see wend home with plodding steers;
Or that from which the husbandman in spleen
Has cleared the timber, and o'erthrown the copse
That year on year lay idle, and from the roots
Uptorn the immemorial haunt of birds;
They banished from their nests have sought the skies;
But the rude plain beneath the ploughshare's stroke
Starts into sudden brightness.
For indeed
The starved hill-country gravel scarce serves the bees
With lowly cassias and with rosemary;
Rough tufa and chalk too, by black water-worms
Gnawed through and through, proclaim no soils beside
So rife with serpent-dainties, or that yield
Such winding lairs to lurk in. That again,
Which vapoury mist and flitting smoke exhales,
Drinks moisture up and casts it forth at will,
Which, ever in its own green grass arrayed,
Mars not the metal with salt scurf of rust—
That shall thine elms with merry vines enwreathe;
That teems with olive; that shall thy tilth prove kind
To cattle, and patient of the curved share.
Such ploughs rich Capua, such the coast that skirts
Thy ridge, Vesuvius, and the Clanian flood,
Acerrae's desolation and her bane.
How each to recognize now hear me tell.
Dost ask if loose or passing firm it be—
Since one for corn hath liking, one for wine,
The firmer sort for Ceres, none too loose
For thee, Lyaeus?—with scrutinizing eye
First choose thy ground, and bid a pit be sunk
Deep in the solid earth, then cast the mould
All back again, and stamp the surface smooth.
If it suffice not, loose will be the land,
More meet for cattle and for kindly vines;
But if, rebellious, to its proper bounds
The soil returns not, but fills all the trench
And overtops it, then the glebe is gross;
Look for stiff ridges and reluctant clods,
And with strong bullocks cleave the fallow crust.
Salt ground again, and bitter, as 'tis called—
Barren for fruits, by tilth untamable,
Nor grape her kind, nor apples their good name
Maintaining—will in this wise yield thee proof:
Stout osier-baskets from the rafter-smoke,
And strainers of the winepress pluck thee down;
Hereinto let that evil land, with fresh
Spring-water mixed, be trampled to the full;
The moisture, mark you, will ooze all away,
In big drops issuing through the osier-withes,
But plainly will its taste the secret tell,
And with a harsh twang ruefully distort
The mouths of them that try it. Rich soil again
We learn on this wise: tossed from hand to hand
Yet cracks it never, but pitch-like, as we hold,
Clings to the fingers. A land with moisture rife
Breeds lustier herbage, and is more than meet
Prolific. Ah I may never such for me
O'er-fertile prove, or make too stout a show
At the first earing! Heavy land or light
The mute self-witness of its weight betrays.
A glance will serve to warn thee which is black,
Or what the hue of any. But hard it is
To track the signs of that pernicious cold:
Pines only, noxious yews, and ivies dark
At times reveal its traces.
