The President having taken the chair, and a quorum being present, the journal of the preceding day shall be read to the end, that any mistake may be corrected that shall have been made in the entries.—Rules of the Senate, 1.

SECTION VII.
CALL OF THE HOUSE.

On a call of the House, each person rises up as he is called, and answereth; the absentees are then only noted, but no excuse to be made till the House be fully called over. Then the absentees are called a second time, and if still absent, excuses are to be heard.—Ord H. of C. 92.

They rise that their persons may be recognized; the voice, in such a crowd, being an inefficient verification of their presence. But in so small a body as the Senate of the United States, the trouble of rising cannot be necessary.

Orders for calls on different days may subsist at the same time.—2 Hats. 72.

SECTION VIII.
ABSENCE.

No member shall absent himself from the service of the Senate without leave of the Senate first obtained. And in case a less number than a quorum of the Senate shall convene, they are hereby authorized to send the sergeant-at-arms, or any other person or persons by them authorized, for any or all absent members, as the majority of such members present shall agree, at the expense of such absent members respectively, unless such excuse for non-attendance shall be made, as the Senate, when a quorum is convened, shall judge sufficient, and in that case the expense shall be paid out of the contingent fund. And this rule shall apply as well to the first convention of the Senate, at the legal time of meeting, as to each day of the session, after the hour is arrived to which the Senate stood adjourned.—Rule 19.

SECTION IX.
SPEAKER.

The Vice-President of the United States shall be President of the Senate, but shall have no vote unless they be equally divided.—Const. U. S. Art I. Sec. 3.

The Senate shall choose their other officers, and also a President pro tempore in the absence of the Vice-President, or when he shall exercise the office of President of the United States.—Const. U. S. Art. I. Sec. 3.
