P. Vergilius Maro, Georgics
J. B. Greenough, Ed.

Many the precepts of the men of old
I can recount thee, so thou start not back,
And such slight cares to learn not weary thee.
And this among the first: thy threshing-floor
With ponderous roller must be levelled smooth,
And wrought by hand, and fixed with binding chalk,
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.
