Columella[1870] informs us, that fruit is kept by being carefully put in earthen vessels, which then receive a coating of pitch, and are placed in wells or cisterns to sink to the bottom. The people of maritime Liguria, in the vicinity of the Alps, first dry their grapes in the sun,[1871] and wrap them up in bundles of rushes, which are then covered with plaster. The Greeks follow a similar plan, but substitute for rushes the leaves of the plane-tree, or of the vine itself, or else of the fig, which they dry for a single day in the shade, and then place in a cask in alternate layers with husks[1872] of grapes. It is by this method that they preserve the grapes of Cos and Berytus, which are inferior to none in sweetness. Some persons, when thus preparing them, plunge the grapes into lie-ashes the moment they take them from the vine, and then dry them in the sun; they then steep them in warm water, after which they put them to dry again in the sun: and last of all, as already mentioned, wrap them up in bundles formed of layers of leaves and grape husks. There are some who prefer keeping their grapes in sawdust,[1873] or else in shavings of the fir-tree, poplar, and ash: while others think it the best plan to hang them up in the granary, at a careful distance from the apples, directly after the gathering, being under the impression that the very best covering for them as they hang is the dust[1874] that naturally arises from the floor. Grapes are effectually protected against the attacks of wasps by being sprinkled with oil[1875] spirted from the mouth. Of palm-dates we have already spoken.[1876] CHAP. 19.
