Upwards of 20 arrow-points--pedunculated, triangular, or heart-shaped. Some fragments of polished hatchets of serpentine; spindle-whorls of terra-cotta (=Fig. 86=, No. 17):--one very large, 4¾ inches in diameter (No. 28), was similar to another found at Chiavichetto. Broken bones, portions of deer-horns, some of which · were made into daggers and pointers; two bone combs ornamented with triangular lines and _graffitti_, similar to those from Castione and Noceto. An oval cake or ring of wood like the supports for vases (No. 25). Of bronze there were various tools and implements. Spear-heads with a tang were most common; No. 19 represents one with two rivet-holes, a type which was also represented at Chiavichetto. A double-edged implement still held the rivet which had fixed it to a handle (No. 22). One arrow-point (No. 23) is similar to one found in the terramara station at Campeggine in the province of Parma. Several fragments of pins, wires, spirals, and small plates of bronze. Among iron objects, all of which were much corroded, was a spear-head (No. 24). Portions of greenish vitreous paste. [Illustration: =Fig. 86.=--VIADANA and stations on the north side of the Po. No. 3 = ¼, 28 = ⅓ and the rest = ½ real size.] The following animals were identified among the osseous remains:--stag, ox, goat, sheep, horse, and pig. Not only as regards the relics but also in internal structure the terramara stations on the north of the Po have been shown to be identical with those on the south side. This we have already seen in the description of Casale Zaffanella. But the point was first established by the indefatigable researches of Chierici, who, in 1881, along with a few other antiquaries, explored the stations at Bellanda and Villa Cappella in the commune of Gazzoldo, about 10 miles west of Mantua. Here all the characteristic features of the terremare--the surrounding dyke, palafitte, and orientation--were clearly established. (B. 372a.) The best investigated terramara in the Bologna district is that at Castellaccio, about three-quarters of a mile to the south of Imola. (B. 457.) The deposits repose on an isolated elevation on the right bank of the river Santerno, and rising nearly 120 feet above its bed; but on it there are no remains of ancient stone buildings, as the name would seem to imply. The hill is of yellowish sand, belonging to the Upper Pliocene. Scarabelli, who has recently published an illustrated monograph of its peculiarities and the antiquities found on it, states that piles were numerous, though many had disappeared by decomposition, only traces of their holes being then detected. Some of the piles were large, measuring over a foot in diameter, and they were placed irregularly. No less than 26 hearths were met with at different levels, and those on the same level were from 4 to 6½ mètres apart.
