The other fruits belong to the fleshy kind, and differ both in the shape and the flesh. The flesh of the various berries,1987 of the mulberry, and of the arbute, are quite different from one another—and then what a difference, too, between the grape, which is only skin and juice,1988 the myxa plum, and the flesh of some berries,1989 such as the olive, for instance! In the flesh of the mulberry there is a juice of a vinous flavour, and the fruit assumes three different colours, being at first white, then red, and ripe when black. The mulberry blossoms one of the very last,1990 and yet is among the first to ripen: the juice of the fruit, when ripe, will stain the hands, but that of the unripe fruit will remove the marks. It is in this tree that human ingenuity has effected the least improvement1991 of all; there are no varieties here, no modifications effected by grafting, nor, in fact, any other improvement except that the size of the fruit, by careful management, has been increased. At Rome, there is a distinction made between the mulberries of Ostia and those of Tusculum. A variety grows also on brambles, but the flesh of the fruit is of a very different nature.1992
