                                SENATORS OF THE UNITED STATES

                   FROM THE FIRST CONGRESS TO THE BEGINNING OF THE SECOND
                        SESSION OF THE ONE HUNDRED SIXTEENTH CONGRESS
                ------------------------------------------------------------

                                 CLASSIFICATION OF SENATORS

                    Under Article I, section 3, clause 2, of the
                Constitution of the United States, relating to the
                classification of Senators in the First and succeeding
                Congresses, it was provided that, ``Immediately after they
                shall be assembled in consequence of the first election they
                shall be divided as equally as may be into three classes.
                The seats of the Senators of the first class shall be
                vacated at the expiration of the second year, of the second
                class at the expiration of the fourth year, and of the third
                class at the expiration of the sixth year, so that one-third
                may be chosen every second year.'' The classification of the
                Senators of the First Congress was made in accordance with
                this provision by lot. The following table shows the classes
                to which the Senators of the First Congress, and from States
                subsequently admitted into the Union, were severally
                assigned, and the succession in each State to the second
                session of the One Hundred Thirteenth Congress.

                                      TERMS OF SENATORS

                    Technically, pursuant to the Twentieth Amendment to the
                Constitution of the United States, ratified January 23,
                1933, the terms of Members of the Senate commence at noon on
                the third day of January and end six years later at noon on
                the third day of January. In view of the impracticality of
                dealing with split days, however, it has been the long
                established practice for payment of salaries, computation of
                allowances, and recording of service to credit a Member for
                the full day of the third of January and to consider the
                term as ended at the close of business on the second of
                January six years later. Accordingly, the service of Members
                of the Senate is shown on that basis in the following
                tables.
