(3) Underlying the relic-bed was a thick bed of stiff loam and sand, into which the piles deeply penetrated. These piles were generally of pine and oak, the former predominating in the proportion of two to one. The dimensions of the lake-dwelling were not accurately ascertained, but the area covered by the dredging operations exceeded 10,000 square yards, and in most of this space piles were found. No stone implements were found, with the exception of the polished discoidal stone sent to Dr. Keller; but the number of bronze objects amounted to 250, most of which were sent to Vienna. Professor Franz Unger made a careful study of the organic remains, and amongst the various fruits, plants, and wood identified by him the most interesting are rye (_Secale cereale_) and the vine (_Vitis vinifera_). The former has not yet been found in any of the terremare or lake-dwellings of North Italy. The osseous remains represented the ordinary domestic animals--dog, sheep, goat, ox, horse, and pig--as well as the stag, roe, wild boar, etc. Besides the bronze objects there were fragments of pottery and one or two Roman coins--one of Trajan and one of Domitian. Meantime archæologists were on the look out for palafittes in other parts of the lake. It appears that as early as 1861 Cav. Martinati detected piles at a place called Rocca di Garda, near Bardolino, on the eastern shore of the lake, which he considered to be the remains of a pile-dwelling. Dr. Alberti also discovered similar evidence in two localities farther south, Il Bor and Porto di Pacengo, which he described in a letter to Martinati in 1864. (B. 77 and 355.) This stimulated the Accad. d'Agricoltura, Arti, e Commercio di Verona to appoint a Commission to investigate the matter; but their labours were soon afterwards discontinued owing to the political disturbances of 1866, and it was not till ten years later that these proposed archæological researches were resumed and the Commission re-constituted. Although on this occasion no bronze objects were found, it cannot be said that the explorations were altogether devoid of interest, as the existence of the reported palafittes was not only confirmed, but a considerable quantity of the osseous remains of the ordinary domestic animals, fragments of pottery (including handles known as _anse lunate_), and a wooden spoon were collected. But the Commission soon abandoned the work as profitless. Then it was that Mr. Alberto Cavazzocca, of Verona, commenced to search Il Bor on his own account, and succeeded in a couple of seasons in securing from it a small collection of antiquities, including objects of stone and bronze.
