15. I come now to the pleasures of the farmer, in which I take amazing delight. These are not hindered by any extent of old age, and seem to me to approach nearest to the ideal wise man's life. For he has to deal with the earth, which never refuses its obedience, nor ever returns what it has received without usury; sometimes, indeed, with less, but generally with greater interest. For my part, however, it is not merely the thing produced, but the earth's own force and natural productiveness that delight me. For received in its bosom the seed scattered broadcast upon it, softened and broken up, she first keeps it concealed therein (hence the harrowing which accomplishes this gets its name from a word meaning "to hide"); next, when it has been warmed by her heat and close pressure, she splits it open and draws from it the greenery of the blade. This, supported by the fibres of the root, little by little grows up, and held upright by its jointed stalk is enclosed in sheaths, as being still immature. When it has emerged from them it produces an ear of corn arranged in order, and is defended against the pecking of the smaller birds by a regular palisade of spikes. Need I mention the starting, planting, and growth of vines? I can never have too much of this pleasure--to let you into the secret of what gives my old age repose and amusement. For I say nothing here of the natural force which all things propagated from the earth possess--the earth which from that tiny grain in a fig, or the grape-stone in a grape, or the most minute seeds of the other cereals and plants, produces such huge trunks and boughs. Mallet-shoots, slips, cuttings, quicksets, layers--are they not enough to fill anyone with delight and astonishment? The vine by nature is apt to fall, and unless supported drops down to the earth; yet in order to keep itself upright it embraces whatever it reaches with its tendrils as though they were hands. Then as it creeps on, spreading itself in intricate and wild profusion, the dresser's art prunes it with the knife and prevents it growing a forest of shoots and expanding to excess in every direction. Accordingly at the beginning of spring in the shoots which have been left there protrudes at each of the joints what is termed an eye. From this the grape emerges and shows itself; which, swollen by the juice of the earth and the heat of the sun, is at first very bitter to the taste, but afterwards grows sweet as it matures; and being covered with tendrils is never without a moderate warmth, and yet is able to ward off the fiery heat of the sun. Can anything be richer in product or more beautiful to contemplate? It is not its utility only, as I said before, that charms me, but the method of its cultivation and the natural process of its growth: the rows of uprights, the cross-pieces for the tops of the plants, the tying up of the vines and their propagation by layers, the pruning, to which
