Much skill is required in building the border. A good formula is: Six parts loamy turf from an old pasture; one part of well-rotted cow manure; one part of old plaster and one part of ground bone. These ingredients are composted and if the work is well done will meet very well the soil and food requirements of the grape. This formula can be varied according to soil conditions and somewhat in accordance with the variety planted. Unless natural drainage is well-nigh perfect, the border must be under-drained with tile and in any case a layer of old brick or stone is needful to make certain that the drainage is perfect. At least two feet, better three feet, of the border compost should be placed above the drainage material. In a border made as described, the grape finds ample root-run, but not too much, as in a surprisingly short time roots are found throughout all parts of this extensive border. The care of the border is a matter of considerable moment and varies, of course, with those in charge. The usual procedure is to spade the outside border, if the border extends outside, before winter, after which it is covered with a coating of well-rotted manure, without any particular attempt having been made to keep out the frost, as a certain amount of freezing outside of the house is held to be beneficial. The inside border must be spaded just before the vines are started in the spring, having been covered previously with well-rotted manure. The time at which the vines are to be started in growth is determined by whether an early or a late crop of grapes is wanted. For an early crop, the vines must be started early in February; for a late crop, a month or even two months later suffices. So started, the first crop of grapes comes on in June or July, the later ones following in August or September. It is related that Napoleon I, to secure saltpetre for making gunpowder, composted "filth, dead animals, urine and offal with alternate layers of turf and lime mortar," and asserted that "a nitre-bed is the very pattern of a vine-border" and that "when the materials have been turned over and over again for a year or two they are in exactly the proper state to yield either gunpowder or grapes." Napoleon's niter-bed is not now considered a good model for a grape-border, as the fruit produced in so rich a soil, though abundant, is coarse and poorly flavored, and the vines complete their own destruction by over-bearing. Gardeners hold that a grape-border may be too rich in plant-food, especially too rich in nitrogen. VARIETIES
