Classification of Savings Banks
We may roughly classify savings institutions into: First, mutual (trustee), or philanthropic; second, stock (including "savings and trust companies"); third, co-operative, or democratic, as exemplified in the co-operative banks of Europe. The first are usually managed by a self-perpetuating body of trustees, who do not share the earnings; the second are managed by the directors elected by the stockholders; the third are managed by officials elected by the members.
A second classification may be made into public and private institutions; the first includes the postal and municipal banks; the private embraces the mutual, stock, and co-operative. A third classification may still be made into the "unit" and the chain system. In the unit system the bank is an independent entity and has no connection (aside from a managerial standpoint) with any other bank. The banks of the United States are all, excepting the Postal Savings Banks and a few branch savings banks, of this character. In the second, the bank is but a part of a chain, as in the postal system, the municipal banks of Germany, and the co-operative credit banks of Europe. We shall briefly review each system.
