Traces of regular gardening and vegetable culture are altogether wanting. Some finds, however, seem to indicate primitive arboriculture, apples and pears having been found dried in slices in the lake-dwellings of the Stone Age; there even appears to be an improved kind of apple besides the wild-growing crab. But although they are chiefly wild unimproved fruit-trees of whose fruit remains have been found, we can imagine that these fruit-trees were planted near the settlements, and the great nutritious and health-giving properties of the fruit, as a supplement to a meat fare, must have been all the more appreciated owing to the lack of green vegetables. The various wild cherries, plums, and sloes were eaten, as also raspberries, blackberries, and strawberries. Beechnut and hazelnut appear as wild food-plants. The original home of the most important cereals--wheat, spelt, and barley--is not known with absolute certainty; probably they came from Central Asia, where they are said to be found wild in the region of the Euphrates. The real millet came from India; peas and the other primeval leguminous plants of Europe, such as lentils and beans, came likewise from the East, partly from India. So that, apart from flax, which probably has a more northern home, the regular cultivated plants of the Stone Age of Central Europe--cereal grasses, millet, and lentils--indicate Asia as their original home. We have therefore a state of things similar to that observed in the case of the domestic animals. [Sidenote: Beginning of the Potter’s Art]
