A court of record has inherent power to preserve order in proceedings before it[Footnote: See Chap. XX.] and, unless other provision be made by law, to appoint a crier or other officer to attend upon its sessions. By statute it is commonly made the duty of the sheriff of the county to attend all courts of record, either personally or by deputy. He also executes such processes as under the practice of the court may be directed to him. Witnesses and jurors are thus summoned by him to appear before the court; arrests and attachments of property are made; and executions are levied to enforce final judgments. * * * * * CHAPTER IX THE ORGANIZATION OF THE COURTS OF THE UNITED STATES The Constitution of the United States (Art. III) provides that there must always be one Supreme Court of the United States. The establishment of such inferior courts as may be deemed proper from time to time is left to Congress. The judicial power of the United States is limited to cases of certain kinds or between certain kinds of parties. Either (1) the subject-matter of the action must be of a kind that concerns the whole nation, or (2) some party to it must be or claim under a political sovereign, or (3) it must be between a citizen of a State of the Union and one of another of the States or of a foreign country. In a few of the second class the Supreme Court is given original jurisdiction: in all others of both classes it has appellate jurisdiction, with such exceptions as Congress may think fit to make, save only that no fact tried by a jury can be thus re-examined, except so far as the rules of the common law would have permitted. Its original jurisdiction is confined to cases affecting ambassadors, ministers, and consuls and those to which a State shall be a party. It is not necessarily exclusive as respects any of them,[Footnote: Ames _v._ Kansas, 111 U. S. Reports, 449, 469.] and by the eleventh amendment to the Constitution is so limited as not to include suits against a State by citizens of any other State or foreign government. In point of fact, few original suits have ever been brought before the court, and almost all of these have been instituted by or against States.
