2. Of the District Courts. 104. In treating of district courts, the same division which was made, in considering circuit courts, will here be adopted, by taking a view, 1. Of their organization and, 2. Of their jurisdiction. Sec. 1. Of the Organization of the District Courts. 105. The United States are divided into districts, in each of which is a court called a district court, which is to consist of one judge, who is to reside in the district for which he is appointed, and to hold annually four sessions. Act of September 24, 1789. By subsequent acts of congress, the number of annual sessions in particular districts, is sometimes more and sometimes less; and they are to be held at various places in the district. There is also a district court in the District of Columbia, held by the chief justice of the circuit court of that district. Sec. 2. Jurisdiction of the District Courts. 106. Their jurisdiction is either civil or criminal.
