Excerpt from Geography of Science
The Growth of the Continent - There are about one hundred million persons in North America at the present time, although a century ago there were scarcely one tenth of that number. This wonderful growth has been largely due to the useful and valuable mineral products of the earth; to the soil and climate which have allowed many different kinds of plants and animals to thrive; and. To the rivers, waterfalls, lakes, and harbors which have made manufacturing and shipping easy.
As it takes time to build a house, and to prepare the boards from trees, the nails from iron ore, and the bricks from clay, so it takes time for the formation of minerals and rocks and for the building of a continent. In fact, millions of years have been required for that work.
The story telling how North America was made is a very interesting one. It has been discovered by a careful study of the rocks; and although there are many ques tions that no man is yet able to answer, we are prepared to tell a part of the story.
