From the river valleys where civilivation originated, it soon spread to parts of Europe, especially to the region on and near the shores of the Mediterranean Sea. On the eastern shores of the Mediterranean lived the Phoenicians, who early became interested in navigation. By sailing the seas they came in contact with other people of the Mediterranean region.
Man has lived on the earth for many thousands of years. He has reached an advanced stage of civilization after having passed through many stages. From primitive origins he made slow progress over a long and difficult road. About six thousand years ago, in the valleys of the Tigris and Euphrates rivers in southwestern Asia, and in the valley of the Nile in northeastern Africa, out civilization had its beginnings. By means of tools, and by the development of various institutions, mankind has made progress.
If we look at our country today, we see a great nation of about .130,000,000 people engaged in many industries in a land where only five hundred years ago the only people were Indians who roamed at will in their primitive state. The Indians here numbering less than 1,000,000 were content to make their living mainly by hunting, fishing, and a little agriculture; they had no desire to cut down the forests and prepare the land for large-scale agriculture; they did not attempt to build industrial centers and carry on extensive trade.
