and they turn mankind topsy-turvy for one nook of that neglected ground in dispute. The earth, if well cultivated, would feed a hundred times more men than now she does. Even the unevenness of ground which at first seems to be a defect turns either into ornament or profit. The mountains arose and the valleys descended to the place the Lord had appointed for them. Those different grounds have their particular advantages, according to the divers aspects of the sun. In those deep valleys grow fresh and tender grass to feed cattle. Next to them opens a vast champaign covered with a rich harvest. Here, hills rise like an amphitheatre, and are crowned with vineyards and fruit trees. There high mountains carry aloft their frozen brows to the very clouds, and the torrents that run down from them become the springs of rivers. The rocks that show their craggy tops bear up the earth of mountains just as the bones bear up the flesh in human bodies. That variety yields at once a ravishing prospect to the eye, and, at the same time, supplies the divers wants of man. There is no ground so barren but has some profitable property. Not only black and fertile soil but even clay and gravel recompense a man's toil. Drained morasses become fruitful; sand for the most part only covers the surface of the earth; and when, the husbandman has the patience to dig deeper he finds a new ground that grows fertile as fast as it is turned and exposed to the rays of the sun. There is scarce any spot of ground absolutely barren if a man do not grow weary of digging, and turning it to the enlivening sun, and if he require no more from it than it is proper to bear, amidst stones and rocks there is sometimes excellent pasture; and their cavities have veins, which, being penetrated by the piercing rays of the sun, furnish plants with most savoury juices for the feeding of herds and flocks. Even sea-coasts that seem to be the most sterile and wild yield sometimes either delicious fruits or most wholesome medicines that are wanting in the most fertile countries. Besides, it is the effect of a wise over-ruling providence that no land yields all that is useful to human life. For want invites men to commerce, in order to supply one another's necessities. It is therefore that want that is the natural tie of society between nations: otherwise all the people of the earth would be reduced to one sort of food and clothing; and nothing would invite them to know and visit one another.
