“III. Fifty Sachemships were created and named in perpetuity in certain gentes of the several Tribes; with power in these gentes to fill vacancies as often as they occurred, by election from among their respective members, and with the further power to depose from office for cause; but the right to invest these Sachems with office was reserved to the General Council. “IV. The Sachems of the Confederacy were also Sachems in their respective Tribes, and with the Chiefs of these Tribes formed the Council of each, which was supreme over all matters pertaining to the Tribe exclusively. “V. Unanimity in the Council of the Confederacy was made essential to every public act. “VI. In the General Council the Sachems voted by Tribes, which gave to each Tribe a negative upon the others. “VII. The Council of each Tribe had power to convene the General Council; but the latter had no power to convene itself. “VIII. The General Council was open to the orators of the people for the discussion of public questions; but the Council alone decided. “IX. The Confederacy had no Chief Executive Magistrate or official head. “X. Experiencing the necessity for a General Military Commander, they created the office in a dual form, that one might neutralise the other. The two principal War-chiefs created were made equal in powers.”[385] [Illustration: CHIMMESYAN HEAD-DRESS REPRESENTING THE WHITE OWL It is made of maple; eyes, tongue, eye-ornament on wings, and ornament at base of the wing-feathers inlaid in Haliotis shell.
