The whole district is well watered by many mountain streams, affluents of the Serchio, furnishing excellent water-power for various mills scattered along their banks. The soil is generally productive, the uplands covered with chestnut-trees and affording fair pasturage for sheep, which are a source of considerable revenue. On the lower levels we find the olive, maize (or _granturco_), a principal article of food, and flax, also the mulberry-tree and silk-worm culture. The region is fairly rich in minerals, stone and marble quarries, manganese, mercury, etc. Here, also, is found the fine red jasper, veined or flecked with white, which has been so effectively used in the Medici Chapel in Florence. We are now quite close upon the walls of Barga, but the long drive in the eager, exhilarating mountain air makes us quite willing to take Pepino's advice and stop for lunch at the Posta, an unpretending wayside inn, beautifully situated, with plain, comfortable rooms commanding fine views, and where, as a recommendation, we were told a Chicago gentleman had once spent seven weeks for his health. In the words of another visitor, we read that "the soup is excellent, and so is the wine;" also, there is trout when the streams are full. We found everything as had been promised, and did ample justice to the excellent food served by a pretty, smiling _contadina_, daughter of the house, who was full of chat and little airs, her young head evidently quite turned by her knowledge of the wandering _forestieri_.
