The great depth of this upper bed of mould, which exists in all the terremare, is very remarkable and most puzzling to archæologists. Boni thinks it was spread over the mound at some posterior time, either for agricultural purposes, or as hygienic precautions, or perhaps from motives of respect to the supposed sacred character of its contents. All the rest of the section was terramara proper, whose contorted and wave-like beds could readily be distinguished. Sticking in the face of the section were innumerable fragments of black pottery, broken bones, and bits of charcoal. All the stuff, before being disposed of, was passed through riddles, and what remained was thrown aside as useless rubbish, the heaps of which could only be estimated by cart-loads. The riddlings consisted almost entirely of broken pottery, among which were occasional clay weights and more frequently spindle-whorls, together with the bones and horns of animals, many of which were converted into implements. Bronze objects were comparatively rare. Part of a large earthen dyke which is supposed to have surrounded the entire mound is still left exposed on the north side. It measured from 20 to 30 feet in breadth at the base and 11½ feet in height. Boni, in his description of this dyke, states that a section which ought to be conical is not so, but more slanting on the outside; also, at the inner side, its contents are occasionally seen to overlap the terramara beds. From this and some other structural details he adduces evidence to show that the dyke had been subsequently added to by the terramaricoli during their occupation of the settlement. Bearing in mind what Pigorini says about Castione, the significance of these observations will be readily perceived. [Illustration: =Fig. 84.=--MONTALE.
