Mr. Dewey—a remarkable instance of the combination of disinterested enthusiasm with thorough business capacity—is devoted to several other causes beside the causes of libraries, and among these is the cause of the decimal system. His experience in the latter field has given him the idea of dividing the departments of human knowledge decimally. His scheme provides for a thousand divisions. Every tenth number embraces some important section of knowledge, and the following nine as many subjections or allied subjects admitting of classification under the principal head. Thus number 500 might represent mathematics in general, and 501 conic sections, analytical geometry, or any other branch of the general subject.

Each book would be numbered in the order of its accession to the library, and receive its place upon the shelves accordingly, so that there never would be any doubt as to the press-mark or position of a book that had once been properly classed.
