Neolithic cave remains occur in somewhat limited areas scattered all over Europe.[37] They have been studied in England, France, Spain, Austria, and Germany in at least fairly large numbers. In Austria the cave province extends through Galicia, Moravia, and Bohemia. Here we find primitive pottery; rude stone and numerous bone implements; domesticated cattle, goats, and pigs. Game was evidently very abundant. The cave-dwellers, apparently, were pioneers in the less habitable regions, living mostly by hunting and fishing, from the increase and products of their herds, and from agriculture to a far less degree. The pottery and implements remind us somewhat of those of the earliest lake-dwellings. But we often find bits of copper and bronze, suggesting a later date or a series of inhabitants whose relics have become much mixed. It would not be at all surprising if primitive manufactures had remained here longer in use than in less isolated regions. A deposit of quite similar general character has been found at Duino, near Monfalcone, at the head of the Gulf of Trieste. A second province lies in Bavaria, between Bamberg and Baireuth. Hoernes considers its remains as also of the same age as the oldest lake-dwellings, but with peculiarities due to the different geographical conditions. The cave provinces of other countries are equally interesting. Every one has its own features and problems. We would naturally expect that these cave-dwellers would represent the least progressive and prosperous members of the population of any country. In our general survey we can afford to give them only a hasty glance. We can easily understand that where chalk or other soft rock occurred artificial grottos were often excavated.[38]
