Lest weeds arise, or dust a passage win
Splitting the surface, then a thousand plagues
Make sport of it: oft builds the tiny mouse
Her home, and plants her granary, underground,
Or burrow for their bed the purblind moles,
Or toad is found in hollows, and all the swarm
Of earth's unsightly creatures; or a huge
Corn-heap the weevil plunders, and the ant,
Fearful of coming age and penury.
Mark too, what time the walnut in the woods
With ample bloom shall clothe her, and bow down
Her odorous branches, if the fruit prevail,
Like store of grain will follow, and there shall come
A mighty winnowing-time with mighty heat;
But if the shade with wealth of leaves abound,
Vainly your threshing-floor will bruise the stalks
Rich but in chaff. Many myself have seen
Steep, as they sow, their pulse-seeds, drenching them
With nitre and black oil-lees, that the fruit
Might swell within the treacherous pods, and they
Make speed to boil at howso small a fire.
Yet, culled with caution, proved with patient toil,
These have I seen degenerate, did not man
Put forth his hand with power, and year by year
Choose out the largest. So, by fate impelled,
Speed all things to the worse, and backward borne
Glide from us; even as who with struggling oars
Up stream scarce pulls a shallop, if he chance
His arms to slacken, lo! with headlong force
The current sweeps him down the hurrying tide.
Us too behoves Arcturus' sign observe,
And the Kids' seasons and the shining Snake,
No less than those who o'er the windy main
Borne homeward tempt the Pontic, and the jaws
Of oyster-rife Abydos. When the Scales
Now poising fair the hours of sleep and day
Give half the world to sunshine, half to shade,
Then urge your bulls, my masters; sow the plain
Even to the verge of tameless winter's showers
With barley: then, too, time it is to hide
Your flax in earth, and poppy, Ceres' joy,
Aye, more than time to bend above the plough,
While earth, yet dry, forbids not, and the clouds
Are buoyant. With the spring comes bean-sowing;
Thee, too, Lucerne, the crumbling furrows then
Receive, and millet's annual care returns,
What time the white bull with his gilded horns
Opens the year, before whose threatening front,
Routed the dog-star sinks. But if it be
For wheaten harvest and the hardy spelt,
Thou tax the soil, to corn-ears wholly given,
Let Atlas' daughters hide them in the dawn,
The Cretan star, a crown of fire, depart,
Or e'er the furrow's claim of seed thou quit,
Or haste thee to entrust the whole year's hope
To earth that would not. Many have begun
Ere Maia's star be setting; these, I trow,
Their looked-for harvest fools with empty ears.
But if the vetch and common kidney-bean
Thou'rt fain to sow, nor scorn to make thy care
Pelusiac lentil, no uncertain sign
Bootes' fall will send thee; then begin,
Pursue thy sowing till half the frosts be done.
Therefore it is the golden sun, his course
Into fixed parts dividing, rules his way
Through the twelve constellations of the world.
Five zones the heavens contain; whereof is one
Aye red with flashing sunlight, fervent aye
From fire; on either side to left and right
Are traced the utmost twain, stiff with blue ice,
And black with scowling storm-clouds, and betwixt
These and the midmost, other twain there lie,
By the Gods' grace to heart-sick mortals given,
And a path cleft between them, where might wheel
On sloping plane the system of the Signs.
And as toward Scythia and Rhipaean heights
The world mounts upward, likewise sinks it down
Toward Libya and the south, this pole of ours
Still towering high, that other, 'neath their feet,
By dark Styx frowned on, and the abysmal shades.
Here glides the huge Snake forth with sinuous coils
'Twixt the two Bears and round them river-wise-
The Bears that fear 'neath Ocean's brim to dip.
There either, say they, reigns the eternal hush
Of night that knows no seasons, her black pall
Thick-mantling fold on fold; or thitherward
From us returning Dawn brings back the day;
And when the first breath of his panting steeds
On us the Orient flings, that hour with them
Red Vesper 'gins to trim his his 'lated fires.
Hence under doubtful skies forebode we can
The coming tempests, hence both harvest-day
And seed-time, when to smite the treacherous main
With driving oars, when launch the fair-rigged fleet,
Or in ripe hour to fell the forest-pine.
Hence, too, not idly do we watch the stars-
Their rising and their setting-and the year,
Four varying seasons to one law conformed.
If chilly showers e'er shut the farmer's door,
Much that had soon with sunshine cried for haste,
He may forestall; the ploughman batters keen
His blunted share's hard tooth, scoops from a tree
His troughs, or on the cattle stamps a brand,
Or numbers on the corn-heaps; some make sharp
The stakes and two-pronged forks, and willow-bands
Amerian for the bending vine prepare.
Now let the pliant basket plaited be
Of bramble-twigs; now set your corn to parch
Before the fire; now bruise it with the stone.
Nay even on holy days some tasks to ply
Is right and lawful: this no ban forbids,
To turn the runnel's course, fence corn-fields in,
Make springes for the birds, burn up the briars,
And plunge in wholesome
