Let us, for illustration, consider for a moment the making of America. The earth, composed of countless aggregations of matter drawn together from the skies, whirled into a globe, settled into a solid mass surrounded by an atmosphere carrying water like a sponge, has reached the stage of development when land and sea have divided the surface between them, and successions of heat and frost, snow, ice, rain, and flood, are busy with their ceaseless carving of the land. Already mountains are wearing down and sea bottoms are building up with their refuse. Sediments carried by the rivers are depositing in strata, which some day will harden into rock. We are looking now at the close of the era which geologists call Archean, because it is ancient beyond knowledge. A few of its rocks are known, but not well enough for many definite conclusions. All the earth's vast mysterious past is lumped under this title. The definite history of the earth begins with the close of the dim Archean era. It is the lapse from then till now, a few hundred million years at most out of all infinity, which ever can greatly concern man, for during this time were laid the only rocks whose reading was assisted by the presence of fossils. During this time the continents attained their final shape, the mountains rose, and valleys, plains, and rivers formed and re-formed many times before assuming the passing forms which they now show. During this time also life evolved from its inferred beginnings in the late Archean to the complicated, finely developed, and in man's case highly mentalized and spiritualized organization of To-day. Surely the geologist's field of labor is replete with interest, inspiration, even romance. But because it has become so saturated with technicality as to become almost a popular bugaboo, let us attempt no special study, but rather cull from its voluminous records those simple facts and perspectives which will reveal to us this greatest of all story books, our old earth, as the volume of enchantment that it really is. With the passing of the Archean, the earth had not yet settled into the perfectly balanced sphere which Nature destined it to be. In some places the rock was more compactly squeezed than in others, and these denser masses eventually were forced violently into neighbor masses which were not so tightly squeezed. These movements far below the surface shifted the surface balance and became one of many complicated and little known causes impelling the crust here to slowly rise and there to slowly fall. Thus in places sea bottoms lifted above the surface and became land, while lands elsewhere settled and became seas. There are areas which have alternated many times between land and sea; this is why we find limestones which were formed in the sea overlying shales which were formed in fresh water, which in turn overlie sandstones which once were beaches--all these now in plateaus thousands of feet above the ocean's level.
