The jurisdiction of the Supreme Court is of two kinds -original and appellate. The appellate jurisdiction is, in turn, of two kinds; that coming by way of writ of error to the courts of the States, and that by appeal from the inferior federal tribunals. The original jurisdiction is determined by the Consti-tution,6a providing that "In all cases affecting ambassadors, other public ministers and consuls, and those in which a State shall be a party, the Supreme Court shall have original jurisdiction."

It has been held that it is not competent for Congress to give to the Supreme Court original jurisdiction in other than these specifically enumerated cases. This doctrine is deduced from the constitutional provision that "in all other cases . . . the Supreme Court shall have appellate jurisdiction, both as to law and fact, with such exceptions and under such regulations as the Congress shall make." 7
