But place the crushed fruit or the wounded animal under conditions which preclude the presence or destroy the life of the germ, and again no change takes place; the grape juice remains sweet and the wound clean.
The latter for a time retains its plumpness, but on the appearance of little black pustules, which first occur on the part primarily affected, the grape begins to shrivel.
This continues until the grape is reduced to a black hard mass, with the folds of skin pressed closely against the seed.
The old-world species is also extensively cultivated in California, but the grape industry of the eastern United States has been developed from native species, chiefly V.
Among the many varieties of trees and plants found are the date palm, mimosa, wild olive, giant sycamores, junipers and laurels, the myrrh and other gum trees (gnarled and stunted, these flourish most on the eastern foothills), a magnificent pine (the Natal yellow pine, which resists the attacks of the white ant), the fig, orange, lime, pomegranate, peach, apricot, banana and other fruit trees; the grape vine (rare), blackberry and raspberry; the cotton and indigo plants, and occasionally the sugar cane.
In three of them at least - the whey cure, the grape cure and the meat cure-a diminution in one or other of the solid constituents of food is associated with the ingestion of an unusually large quantity of water.
At first these are marked only by small brown spots; but the spots spread and fuse together, the skin of the grape is destroyed, and the flesh decays, the seed only remaining apparently untouched.
When the grape is ripe, the sugar has attained to a maximum and the acidity is very much reduced; the tannin has entirely disappeared.
Since 1890 the cultivation of the grape and the manufacture of wine have considerably extended, especially in the department of Salto, Montevideo, Canelones and Colonia.
The sun is sufficiently powerful to cause the evaporation of the water in the grape through the skin without any preliminary loosening of the latter by the action of the botrytis cinerea or any other micro-organism.
