(_A digression on the maintenance of vineyards_) VIII. There be those who assert that the cost of maintaining a vineyard eats up the profit. What kind of vineyard? I ask. For there are several: in one the vines grow on the ground without props, as in Spain; in another, which is the kind common in Italy, the vines climb and are trained either separately on props or one with another on a trellis, which last is what is called marrying the vine. There are four kinds of trellis in use--made out of poles, of reeds, of ropes and of vines themselves, which are in use respectively in Falerum, in Arpinum, in Brundisium and in Mediolanum. There are two methods of training the vine on trellises, one upright, as is done in the country of Canusium; the other crossed and interwoven, as is the practice generally throughout Italy. If one obtains the material for his trellises from his own land, the expense of maintaining that kind of vineyard is negligible, nor is it burdensome if the material is procured from the neighbourhood. Such trellis material, as has been described, can be grown at home by planting willows, reeds and rushes, or some thing of that kind; but if you propose to rely on the vines to form their own trellis, then you must plant an _arbustum_ where the vines can be trained on trees, such as maples, which the inhabitants of Mediolanum use for that purpose; or fig trees, on which the people of Canusium train their vines. Likewise there are four kinds of props used for the cultivation of unwedded vines; first, the planted post, which is called _ridicum_ and is best when fashioned out of oak or juniper; second, poles cut in the swamp, and the more seasoned they are the longer they will last, but it is the practice to reset them upside down when they rot out in the ground; third, for lack of some thing better, a bundle of reeds tied together and thrust into a pointed tube of baked clay, which is then planted in the ground and serves to preserve the reeds from water rot; the fourth is what may be called the natural prop, when vines are swung from tree to tree. Vines should be trained to the height of a man and the interval between the props should be sufficient to give room for a yoke of oxen to plough. The least expensive kind of a vineyard is that which brings wine to the jug without the aid of any sort of prop. There are two of this kind, one in which the earth serves as a bed for the grapes, as in many places in Asia, and where usually the foxes share the crop with man;[64] or, if mice appear, it is they who make the vintage, unless you put a mouse trap in every vine, as they do on the island of Pandataria. The other kind of vineyard, is that where each shoot which promises to bear grapes is lifted from the earth and supported about two feet off the ground by a forked stick: by this means the grapes, as they form, learn to hang as it were from a branch and do not have to be taught after the vintage; they are held in place with a bit of
