Excerpt from First Lessons in Geology: To Accompany the Chautauqua Scientific Diagrams
Now if there has been a recent shower, and the stream is rather high and the water thick and turbid, should we take up a tumbler-full of the water and allow it to settle, we shall see that the coarser particles fall to the bottom first and form a layer or stratum of gravel; above it is next deposited a layer of sand, and finally when the water has become clear, all the sedi ment having fallen to the bottom, we shall find uppermost a stratum of very fine sand, so fine that we cannot easily distin guish the particles, and this is mud. The entire deposit is said to be, in geological language, a sedimentary deposit.

Excerpt from First Lessons in Geology
If we walk out of the town or village in which we live, and observe carefully the cuttings by the roadside, or the bank of some stream or railroad cut, we shall see overlying the sand or gravel a layer of soil or loam. Upon closely examining this soil we shall find that it is not of the same nature throughout, but that next to the surface it is composed of dead and decaying leaves and stems of plants mixed with the roots of the trees and shrubs growing in the soil. Deeper down, the soil will be found to lie less dark and more sandy. Finally we come to the sand or gravel. Let us now examine the gravel; and the coarser it is, the better for our purpose. Taking - up a handful let us turn over the miniature pebbles. There are little masses of milk-white quartz, which are more or less angular, because quartz is the hardest mineral among those to be found; we also find little pieces of rounded feldspar, a flesh-colored or whitish mineral which is softer than the quartz because we can break it easier, and it is easily scratched by the quartz; we also find minute scales of mica which glisten in the sun. These three minerals form granite. We also find pebbles of a fine-grained granite, and mingled with them pebbles of granite with the minerals composing it arranged in layers; this is called gneiss; besides these we may find little pieces of a greenish-black, very hard rock called greenstone or trap. If the cut has been freshly made we shall see that the gravel or sand is arranged in regular layers called strata, and that the sand bank is layered, or stratified. This division into layers or strata is called stratification.
