All this we gather from the remains of the Swiss pile dwellings, and such was the character of the human life that spread over Europe, coming from the south and from the east with the forests as, 10,000 or 12,000 years ago, the reindeer and the Reindeer Men passed away. It is evident that we have here a way of life already separated by a great gap of thousands of years of invention from its original Palæolithic stage. The steps by which it rose from that condition we can only guess at. From being a hunter hovering upon the outskirts of flocks and herds of wild cattle and sheep, and from being a co-hunter with the dog, man by insensible degrees may have developed a sense of proprietorship in the beasts and struck up a friendship with his canine competitor. He learnt to turn the cattle when they wandered too far; he brought his better brain to bear to guide them to fresh pasture. He hemmed the beasts into valleys and enclosures where he could be sure to find them again. He fed them when they starved, and so slowly he tamed them. Perhaps his agriculture began with the storage of fodder. He reaped, no doubt, before he sowed. The Palæolithic ancestor away in that unknown land of origin to the south-east first supplemented the precarious meat supply of the hunter by eating roots and fruits and wild grains. Man storing graminiferous grasses for his cattle might easily come to beat out the grain for himself. § 4 How did man learn to sow in order that he might reap? We may hesitate here to guess at the answer to that question. But a very great deal has been made of the fact that wherever sowing occurs among primitive people in any part of the world, it is accompanied by a human sacrifice or by some ceremony which may be interpreted as the mitigation and vestige of an ancient sacrificial custom. This is the theme of Sir J. G. Frazer’s _Golden Bough_. From this it has been supposed that the first sowings were in connection with the burial of a human being, either through wild grain being put with the dead body as food or through the scattering of grain over the body. It may be argued that there is only one reason why man should have disturbed the surface of the earth before he took to agriculture, and that was to bury his dead; and in order to bury a dead body and make a mound over it, it was probably necessary for him to disturb the surface over a considerable area. Neolithic man’s chief apparatus for mound-making consisted of picks of deer’s horn and shovels of their shoulder-blades, and with this he would have found great difficulty in making a deep excavation. Nor do we find such excavations beside the barrows. Instead of going down into tough sub-soil, the mound-makers probably scraped up some of the surface soil and carried it to the mound. All this seems probable, and it gives just that wide area of bared and turned-over earth upon which an eared grass, such as barley, millet, or primitive wheat, might have seeded and grown.
