The chief tool and weapon of Neolithic man was his axe; his next the bow and arrow. His arrow heads were of flint, beautifully made, and he lashed them tightly to their shafts. Probably he prepared the ground for his sowing with a pole, or a pole upon which he had stuck a stag’s horn. Fish he hooked or harpooned. These implements no doubt stood about in the interior of the house, from the walls of which hung his fowling-nets. On the floor, which was of clay or trodden cow-dung (after the fashion of hut floors in India to-day), stood pots and jars and woven baskets containing grain, milk, and such-like food. Some of the pots and pans hung by rope loops to the walls. At one end of the room, and helping to keep it warm in winter by their animal heat, stabled the beasts. The children took the cows and goats out to graze, and brought them in at night before the wolves and bears came prowling.

He also had earthenware drums across which skins were stretched; perhaps also he made drums by stretching skins over hollow tree stems.[58] We do not know when man began to sing, but evidently he was making music, and since he had words, songs were no doubt being made. To begin with, perhaps, he just let his voice loose as one may hear Italian peasants now behind their ploughs singing songs without words. After dark in the winter he sat in his house and talked and sang and made implements by touch rather than sight. His lighting must have been poor, and chiefly firelight, but there was probably always some fire in the village, summer or winter. Fire was too troublesome to make for men to be willing to let it out readily. Sometimes a great disaster happened to those pile villages, the fire got free, and they were burnt out. The Swiss deposits contain clear evidence of such catastrophes.
