TORBIERA DI VALCUVIA.
In 1870 Professor Leopoldi Maggi described the remains of a palafitte found in "un bacino torboso" between Santa Maria di Cuveglio and Cavona. (B. 187.) This basin lies among glacial débris, and was formerly a small lake, but in modern times it became entirely filled up with peat. On the surface there was a layer of vegetable soil 10 inches thick, then spongy peat to the depth of 3 feet, and then a layer of more solid peat about 1 foot 8 inches thick. Underneath these layers was a blackish muddy deposit, extending to an unknown depth, into which the piles were inserted. These piles were from 5 to 10 feet long, and 8 to 10 inches in diameter. They were closely set, and along with them were several beams lying horizontally. The relics consisted of pottery, knives of bronze and iron, charcoal, etc., all of which were dispersed.
