We find a somewhat small dog (Canis familiaris palustris) closely resembling that of the Danish shell-heaps. It was apparently of the jackal type, and much like the modern Spitz. This would have been an excellent watch-dog to give warning of the approach of enemies. But at the close of the Neolithic, with the increase of flocks of sheep, a larger dog more closely related to the wolf seems to have spread widely through the country (Canis familiaris matris optimæ Juit). This form was much like, and probably the ancestor of, our present sheep-dogs. A third form (Canis intermedius) also occurs. The origin and relationships of the various forms of this oldest domesticated animal are still anything but clear. That they all go back to the jackal and the wolf rather than to a form like the Australian dingo, still seems to be most generally accepted. (But see Schenk.[57])

Man gained the dog by domesticating the jackal and different species of wolves in different parts of the world and then by crossing, or, by a more or less unconscious selection, bred different varieties, until we have at present a chaos of intermingled forms. Something similar but on a smaller scale was true of the domestic cattle. One kind of domestic cattle appears fully domesticated in the oldest lake-dwellings. It is unlike any wild European form. This is the Bos brachyceros. It was almost certainly imported. Mingled with its forms we find those of the Bos primigenius, a native of Europe and North Asia, but apparently not domesticated. This is the urus, which was common in Europe in Cæsar’s day, and lasted in central Europe until 1000 A. D. and still lingers in Poland.[58] This was a very large and powerful form with long spreading horns, whose domestication appears to have commenced toward the close of the Neolithic period. It is not improbable that it was domesticated, or at least tamed, independently in different countries at quite different times. Raising of cattle was at its height during the Bronze Age; afterward the results seem to decline and the cattle to degenerate.

One of the Vaphio vases of about 1500 B. C. represents the capture of large, long-horned cattle in a net, while the second shows similar animals tamed. Apparently the smaller and lighter brachyceros was first tamed, and this success led to a series of experiments with the larger and more difficult form.[59]

If we draw a line from northwestern Russia diagonally across Europe southwestward to the mouth of the Rhone, it will divide fairly well the distribution of the descendants of those two forms. To the eastward in Russia and Austria, also generally through Germany, and extending also along the shores of the Baltic, we find the large, heavy, usually long-horned descendants of the primigenius stock. The cattle of Spain, and southward into Africa, of France and England, are more of the short-horned, light-built, smaller brachyceros type. Holstein and Jersey are good representatives of the two types, though the Holsteins are, perhaps, a somewhat marked variety. Some regard the cattle of the Scotch highlands as the best representatives of the primigenius type, though reduced in size. This same type, on account of its size and endurance of harsh climate, has furnished the range cattle of our Western plains.

Two fairly distinct forms of swine occur in the lake-dwellings. The first is the so-called turbary pig (Sus scrofa palustris). This is a small form with comparatively long legs. It differs markedly from the wild boar, and was probably imported already domesticated. Being more or less left to feed and shift for itself, it may well have declined in size from its primitive oriental ancestors. Remains of the larger European wild boar (Sus scrofa ferus L.) also occur from the beginning as products of the hunt. But during the Bronze period domesticated descendants of this variety grow numerous, and are crossed with the smaller turbary pig.

“The domestic sheep,” says Brehm, “is a quiet, gentle, patient, simple, will-less, cowardly, wearisome animal. It has no character. It understands and learns nothing; is incapable of helping itself.”[60] It is certainly absolutely dependent upon man for guidance and protection. This lies partly in its inherited nature and original surroundings, but suggests long domestication. Like the goat, it is originally a mountain form, but adapts itself readily to the dry herbage of the steppe. It is not a native of central Europe but introduced. It is much rarer than the goat in the oldest lake-dwellings, but gradually becomes more abundant, especially in the Bronze period.

The turbary sheep (Ovis aries palustris) is very small, with slender legs, long narrow skull, and bones somewhat like those of the goat. It was certainly not developed in Switzerland, and before it arrived there it had apparently been much modified by conditions of life or by crossing. ing. Its anatomical characteristics are made up of at least three wild forms. The first of these is the goat-like maned sheep (Ovis tragelaphus) ranging over the mountains of northern Africa, extending across into Abyssinia. This form seems to have been domesticated in Egypt before the middle of the fourth millennium. At a much later date, in Homeric times, herds of sheep of a similar form were kept in Greece. It was much larger than the turbary form.

The arkal (Ovis arkal) is the steppe sheep of central and western Asia. It is the ancestor of the oriental and African fat-tailed sheep. The western Asiatic forms seem to have developed the fine wool at the expense of the coarse hair, like that of the goat and of many other forms.

A third form is the Moufflon, of the mountains around the Mediterranean and of its larger islands—here probably introduced. Similar forms appear in Europe during the Bronze period.
