Mr.Emerson well observes, that "the effect of a house is immense on human tranquillity, power, and refinement.

A man in a cave or a camp--a nomad--dies with no more estate than the wolf or the horse leaves.

But so simple a labour as a house being achieved, his chief enemies are kept at bay.

He is safe from the teeth of wild animals, from frost, sunstroke, and weather; and fine faculties begin to yield their fine harvest.

Inventions and arts are born, manners, and social beauty and delight." But to build a house which should serve for shelter, for safety, and for comfort--in a word, as a home for the family, which is the nucleus of society--better tools than those of stone were absolutely indispensable.
Hence most of the early European tribes were nomadic: first hunters, wandering about from place to place like the American Indians, after the game; then shepherds, following the herds of animals which they had learnt to tame, from one grazing-ground to another, living upon their milk and flesh, and clothing themselves in their skins held together by leathern thongs.
