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.
SECT. XII. Of Plants.
All that the earth produces being corrupted, returns into her bosom, and becomes the source of a new production. Thus she resumes all she has given in order to give it again. Thus the corruption of plants, and the excrements of the animals she feeds, feed her, and improve her fertility. Thus, the more she gives the more she resumes; and she is never exhausted, provided they who cultivate her restore to her what she has given. Everything comes from her bosom, everything returns to it, and nothing is lost in it. Nay, all seeds multiply there. If, for instance, you trust the earth with some grains of corn, as they corrupt they germinate and spring; and that teeming parent restores with usury more ears than she had received grains. Dig into her entrails, you will find in them stone and marble for the most magnificent buildings. But who is it that has laid up so many treasures in her bosom, upon condition that they should continually produce themselves anew? Behold how many precious and useful metals; how many minerals designed for the conveniency of man!
Admire the plants that spring from the earth: they yield food for the healthy, and remedies for the sick. Their species and virtues are innumerable. They deck the earth, yield verdure, fragrant flowers, and delicious fruits. Do you see those vast forests that seem as old as the world? Those trees sink into the earth by their roots, as deep as their branches shoot up to the sky. Their roots defend them against the winds, and fetch up, as it were by subterranean pipes, all the juices destined to feed the trunk. The trunk itself is covered with a tough bark that shelters the tender wood from the injuries of the air. The branches distribute by several pipes the sap which the roots had gathered up in the trunk. In summer the boughs protect us with their shadow against the scorching rays of the sun. In winter, they feed the fire that preserves in us natural heat. Nor is burning the only use wood is fit for; it is a soft though solid and durable matter, to which the hand of man gives, with ease, all the forms he pleases for the greatest works of architecture and navigation. Moreover, fruit trees by bending their boughs towards the earth seem to offer their crop to man. The trees and plants, by letting their fruit or seed drop down, provide for a numerous posterity about them. The tenderest plant, the least of herbs and pulse are, in little, in a small seed, all that is displayed in the highest plants and largest tree. Earth that never changes produces all those alterations in her bosom.
SECT. XIII. Of Water.
Let us now behold what we call water. It is a liquid, clear, and transparent body. On the one hand it flows, slips, and runs away; and on the other it assumes all the forms of the bodies that surround it, having properly none of its own. If water were more rarefied, or thinner, it would be a kind of air; and so the whole surface of the earth would be dry and sterile. There would be none but volatiles; no living creature could swim; no fish could live; nor would there be any traffic by navigation. What industrious and sagacious hand has found means to thicken the water, by subtilising the air, and so well to distinguish those two sorts of fluid bodies? If water were somewhat more rarefied, it could no longer sustain those prodigious floating buildings, called ships. Bodies that have the least ponderosity would presently sink under water. Who is it that took care to frame so just a configuration of parts, and so exact a degree of motion, as to make water so fluid, so penetrating, so slippery, so incapable of any consistency: and yet so strong to bear, and so impetuous to carry off and waft away, the most unwieldy bodies? It is docile; man leads it about as a rider does a well-managed horse. He distributes it as he pleases; he raises it to the top of steep mountains, and makes use of its weight to let it fall, in order to rise again, as high as it was at first. But man who leads waters with such absolute command is in his turn led by them. Water is one of the greatest moving powers that man can employ to supply his defects in the most necessary arts, either through the smallness or weakness of his body. But the waters which, notwithstanding their fluidity, are such ponderous bodies, do nevertheless rise above our heads, and remain a long while hanging there. Do you see those clouds that fly, as it were, on the wings of the winds? If they should fall, on a sudden, in watery pillars, rapid like a torrent, they would drown and destroy everything where they should happen to fall, and the other grounds would remain dry. What hand keeps them in those pendulous reservatories, and permits them to fall only by drops as if they distilled through a gardener’s watering-pot? Whence comes it that in some hot countries, where scarce any rain ever falls, the nightly dews are so plentiful that they supply the want of rain; and that in other countries, such as the banks of the Nile and Ganges, the regular inundation of rivers, at certain seasons of the year, never fails to make up what the inhabitants are deficient in for the watering of the ground? Can one imagine measures better concerted to render all countries fertile and fruitful?
Thus water quenches, not only the thirst of men, but likewise of arid lands: and He who gave us that fluid body has carefully distributed it throughout the earth, like pipes in a garden. The waters fall from the tops of mountains where their reservatories are placed. They gather into rivulets in the bottom of valleys. Rivers run in winding streams through vast tracts of land, the better to water them; and, at last, they precipitate themselves into the sea, in order to make it the centre of commerce for all nations. That ocean, which seems to be placed in the midst of lands, to make an eternal separation between them, is, on the contrary, the common rendezvous of all the people of the earth, who could not go by land from one end of the world to the other without infinite fatigue, tedious journeys, and numberless dangers. It is by that trackless road, across the bottomless deep, that the whole world shakes hands with the new; and that the new supplies the old with so many conveniences and riches. The waters, distributed with so much art, circulate in the earth, just as the blood does in a man’s body. But besides this perpetual circulation of the water, there is besides the flux and reflux of the sea. Let us not inquire into the causes of so mysterious an effect. What is certain is that the tide carries, or brings us back to certain places, at precise hours. Who is it that makes it withdraw, and then come back with so much regularity? A little more or less motion in that fluid mass would disorder all nature; for a little more motion in a tide or flood would drown whole kingdoms. Who is it that knew how to take such exact measures in immense bodies? Who is it that knew so well how to keep a just medium between too much and too little? What hand has set to the sea the unmovable boundary it must respect through the series of all ages by telling it: There, thy proud waves shall come and break? But these waters so fluid become, on a sudden, during the winter, as hard as rocks. The summits of high mountains have, even at all times, ice and snow, which are the springs of rivers, and soaking pasture-grounds render them more fertile. Here waters are sweet to quench the thirst of man; there they are briny, and yield a salt that seasons our meat, and makes it incorruptible. In fine, if I lift up my eyes, I perceive in the clouds that fly above us a sort of hanging seas that serve to temper the air, break the fiery rays of the sun, and water the earth when it is too dry. What hand was able to hang over our heads those great reservatories of waters?
