An assembly of depu- ties convened from different governments to treat of peace or of other international affairs; as the Congress of Berlin to settle the terms of peace between Russia and Turkey in 1878, composed of representations of the great Powers of Europe In theory a congress may conclude a treaty, while a conference is for consulta- tion, and its result, ordinarily a protocol, prepares the way for a treaty. See Cent. Dict.; Encyc. Dict. But this is not always true, as the Berlin conference of 1889 was composed of plenipotentiaries and its delib- erations resulted in a treaty. The legislative body of the United States, composed of the senate and house of repre- sentatives (q. v.). U. S. Const. art. 1, § 1. Each house is the judge of the election and qual ifications of its members. A majority of each house is a quorum; but a smaller number may adjourn from day to day, and compel the attendance of ab- sent members. Each house may make rules, punish its members, and by a two-thirds vote expel a mem- ber. Each house must keep a journal and publish the same, excepting such parts as may, in their judg- ment, require secrecy, and record the yeas and nays at the desire of one-fifth of the members pres- ent. Art. 1, s. 5. A court is bound to assume that the journal speaks the truth and cannot receive oral testimony to impeach its correctness; 144 U. S. 1. The members of both houses are in all cases, ex- cept treason, felony, and breach of the peace, priv- ileged from arrest while attending to and returning from the session of their respective houses; and no member can be questioned ed in any other place for any speech or debate in either house. U. S. Const. art. 1, s. 6. Each house of congress has claimed and exercised the power to punish contempts and breaches of its privileges, on the ground that all public fune- tionaries are essentially invested with the powers of self-preservation, and that whenever authorities are given, the means of carrying them into execution. are given by necessary implication.

S. 188, it was held that although the house can pun- ish its own members for disorderly conduct or for failure to attend its sessions, and can decide cases of contested elections and deterinine the qual- ifications of its members, and exercise the sole power of impeachment of officers of the govern- ment, and may, when the examination of witnesses is necessary to the performance of these duties, fine or imprison a contumacious witness, there is not found in the constitution any general power vested in either house to punish for contempt. The order of the house ordering the imprisonment of a witness for refusing to answer certain questions put to him by the house, concerning the business of a real estate partnership of which he was a member, and to produce certain books in relation thereto, was held void and no defence on the part of the sergeant-at-arms in an action by the witness for false imprisonment. The members of the com- mittee, who took no actual part in the imprison- ment, were held not liable to such action. cases in which the power had been exercised are numerous. See Barclay, Dig. Rules of Hou. Reps. U. S. tit. Privilege. This power, however, extends no further than imprisonment; and that will con- tinue no further than the duration of the power that imprisons. The imprisonment will therefore terminate with the adjournment or dissolution of congress. The The rules of proceeding in each house are sub- stantially the same the house of representatives choose their own speaker; the vice-president of the United States is, ex officio, president of the senate. For rules of proceeding and forms observed in passing laws, see Barclay's Dig. When a bill is engrossed, and has received the sanction of both houses, it is sent to the president for his approbation. If he approves of the bill, he signs it. If he does not, it is returned, with his ob- jections, to the house in which it originated, and, that house enters the objections at large on its journal and proceeds to reconsider it. If, after such reconsideration, two-thirds of the house agree to pass the bill, it is sent, together with the objec tions, to the other house, by which it is likewise re- considered, and, if approved by two-thirds of that house, it becomes a law. But in all such cases the votes of both houses are determined by yeas and nays, and the names of the persons voting for and against the bill are to be entered on the journal of each house respectively. If any bill shall not be returned by the president within ten days (Sundays excepted) after it shall have been presented to him, the same shall be a law, in like manner as if he h
