Synopsis
                  Excerpt from The Popular Educator, Vol. 3: A Complete Encyclopędia of Elementary, Advanced and Technical Education
The derivation of the word Geology (71; [ghee], the earth, and A670: a discourse, or a reasoning) indicates the main direction of the science. It confines its attention to a description of the solid crust of the earth, and to the elucidation of those forces and causes which have produced the changes the surface of our planet has undergone. To aid him in his investigation, the geologist needs the aid of the botanist, the zoologist, the chemist, the mineralogist, the physicist, and even of the mathematician.
Although the subject looks formidable to the general reader, it is not only fraught with the deepest interest, but by far its greatest part may be traversed by common sense. Moreover, its study commends itself to all, since it requires no expensive apparatus, nor yet a preparation which all other sciences demand ere the student can enter on their practice. Young and old, gifted with observation, may at once become practical geologists; and by never passing a stone-heap without an ex amination, or never leaving a quarry or gravel-pit unsearched, they will soon lay the foundation of a geological cabinet, and be efficient labourers in the extension of geological research.
