their constructions according to circumstances. But, in fact, there is much less uniformity in these terremare than is often found in the dwellings of animals; therefore I maintain logically, that even prehistoric men changed their mode of living according to place, time, and circumstances; and that the terramaricoli did not live solely in pools of water, as some assert, but had settlements both in the water and on dry land, and that the terramara beds are the results of the latter. In some of the terrestrial settlements they probably had pile-dwellings, while in others they lived in huts or tents. Some at least of the land settlements were defended by dykes and ditches." (B. 119, 2nd ed., p. 402.) Pigorini, on the other hand, looked favourably on the major portion of Chierici's generalisations, and in the course of explorations conducted by him at Casaroldo in 1874 (B. 266 and 297) he found everything not only in harmony with his views but some additional facts that seemed to strengthen that portion of his theory in which he maintained that the palafitte was the normal method adopted in the structure of the terremare, whatever the nature of the locality might be in which they were constructed. Thus at Casaroldo, although there was both a ditch and a dyke surrounding the basin containing the palafitte, it had no peaty understratum (_terra uliginosa_), as at Castione, but a substance precisely identical with the superimposed deposits. Here also there were traces of piles on a higher level. Almost coincident with the publication of Chierici's theory of the terremare, in 1871, was the International Congress of Anthropology and Prehistoric Archæology at Bologna, which gave an immense impetus to such studies. Indeed, the decade which followed may be characterised as the Augustan age in the department of prehistoric archæology in Italy. The remarkable discoveries in the old cemeteries of Bologna, and in Etruscan tombs elsewhere in the Circumpadana district, together with the increasing number of prehistoric stations in lakes, turbaries, caverns, etc., greatly widened the field of research and added to the difficulty of deciphering, from amidst the endless overlappings of their remains, the history of the various civilisations which formerly characterised the country. In order to facilitate these studies the _Bullettino Paletnologia Italiana_ was established at the commencement of 1875, under the joint editorship of Chierici, Pigorini, and Strobel. This periodical has done much good and is still in a flourishing condition. SPECIAL INVESTIGATIONS AT CASTIONE.
