Again, where will you find the man who does not know that, in marching through a defile, it is better to occupy the points of vantage first? Yet this measure of precaution too is duly taken by some and neglected by others.

So, too, everyone will say that in agriculture there is nothing so good as manure, and their eyes tell them that nature produces it. All know exactly how it is produced, and it is easy to get any amount of it; and yet, while some take care to have it collected, others care nothing about it.

Yet the rain is sent from heaven, and all the hollows become pools of water, and the earth yields herbage of every kind which must be cleared off the ground by the sower before sowing; and the rubbish he removes has but to be thrown into water, and time of itself will make what the soil likes. For every kind of vegetation, every kind of soil in stagnant water turns into manure.

And again, all the ways of treating the soil when it is too wet for sowing or too salt for planting are familiar to all men—how the land is drained by ditches, how the salt is corrected by being mixed with saltless substances, liquid or dry. Yet these matters, again, do not always receive attention.

Suppose a man to be wholly ignorant as to what the land can produce, and to be unable to see crop or tree on it, or to hear from anyone the truth about it, yet is it not far easier for any man to prove a parcel of land than to test a horse or to test a human being? For the land never plays tricks, but reveals frankly and truthfully what she can and what she cannot do.

I think that just because she conceals nothing from our knowledge and understanding, the land is the surest tester of good and bad men. For the slothful cannot plead ignorance, as in other arts: land, as all men know, responds to good treatment.

Husbandry is the clear accuser of the recreant soul. For no one persuades himself that man could live without bread; therefore if a man will not dig and knows no other profit-earning trade, he is clearly minded to live by stealing or robbery or begging—or he is an utter fool.

Farming, he added, may result in profit or in loss; it makes a great difference to the result, even when many labourers are employed, whether the farmer takes care that the men are working during the working hours or is careless about it. For one man in ten by working all the time may easily make a difference, and another by knocking off before the time;

and, of course, if the men are allowed to be slack all the day long, the decrease in the work done may easily amount to one half of the whole.

Just as two travellers on the road, both young and in good health, will differ so much in pace that one will cover two hundred furlongs to the other’s hundred, because the one does what he set out to do, by going ahead, while the other is all for ease, now resting by a fountain or in the shade, now gazing at the view, now wooing the soft breeze;

so in farm work there is a vast difference in effectiveness between the men who do the job they are put on to do and those who, instead of doing it, invent excuses for not working and are allowed to be slack.

In fact, between good work and dishonest slothfulness there is as wide a difference as between actual work and actual idleness. Suppose the vines are being hoed to clear the ground of weeds: if the hoeing is so badly done that the weeds grow ranker and more abundant, how can you call that anything but idleness?

These, then, are the evils that crush estates far more than sheer lack of knowledge. For the outgoing expenses of the estate are not a penny less; but the work done is insufficient to show a profit on the expenditure; after that there’s no need to wonder if the expected surplus is converted into a loss.

On the other hand, to a careful man, who works strenuously at agriculture, no business gives quicker returns than farming. My father taught me that and proved it by his own practice. For he never allowed me to buy a piece of land that was well farmed; but pressed me to buy any that was uncultivated and unplanted owing to the owner’s neglect or incapacity.
