The Drift CHAPTER I. THE CHARACTERISTICS OF THE DRIFT. READER,--Let us reason together:-- What do we dwell on? The earth. What part of the earth? The latest formations, of course. We live upon the top of a mighty series of stratified rocks, laid down in the water of ancient seas and lakes, during incalculable ages, said, by geologists, to be from ten to twenty miles in thickness. Think of that! Rock piled over rock, from the primeval granite upward, to a height four times greater than our highest mountains, and every rock stratified like the leaves of a book; and every leaf containing the records of an intensely interesting history, illustrated with engravings, in the shape of fossils, of all forms of life, from the primordial cell up to the bones of man and his implements. But it is not with the pages of this sublime volume {p. 2} we have to deal in this book. It is with a vastly different but equally wonderful formation. Upon the top of the last of this series of stratified rocks we find THE DRIFT. What is it? Go out with me where yonder men are digging a well. Let us observe the material they are casting out. First they penetrate through a few inches or a foot or two of surface soil; then they enter a vast deposit of sand, gravel, and clay. It may be fifty, one hundred, five hundred, eight hundred feet, before they reach the stratified rocks on which this drift rests. It covers whole continents. It is our earth. It makes the basis of our soils; our railroads cut their way through it; our carriages drive over it; our cities are built upon it; our crops are derived from it; the water we drink percolates through it; on it we live, love, marry, raise children, think, dream, and die; and in the bosom of it we will be buried.
