The legislative, executive, and judicative functions have not been differentiated in Indian society as found among the Siouan groups. Two tendencies or processes of opposite character have been observed among the tribes, viz, consolidation and segregation. The effects of consolidation are conspicuous among the Omaha, Kansa, Osage, and Oto, while segregation has affected the social organization among the Kansa, Ponka, and Teton. There have been instances of emigration from one tribe to another of the same linguistic family; and among the Dakota new gentes have been formed by the adoption into the tribe of foreigners, i.e., those of a different stock. Two classes of organization are found in the constitution of the state, viz, (1) major organizations, which relate directly to government, and (2) minor organizations, which relate only indirectly to government. The former embraces the state functionaries, the latter comprises corporations. Although the state functionaries are not clearly differentiated, three classes of such men have been recognized: chiefs, policemen or soldiers, and young men or "the common people." The chiefs are the civil and religious leaders of the masses; the policemen are the servants of the chiefs; the young men are such as have not distinguished themselves in war or in any other way. These last have no voice in the assembly, which is composed of the chiefs alone. Among the Omaha there is no military class, yet there is a war element which is regulated by the Elk gens. The ¢ixida gens and part of the Nika*d*aɔna gens of the Ponka tribe are considered to be the warriors of the tribe, though members of other gentes have participated in war. In the Kansa tribe two gentes, the Large Hañga and the Small Hañga, form the phratry connected with war, though warriors did not necessarily belong to those gentes alone. In the Osage camping circle all the gentes on the right side are war gentes, but the first and second, reckoning from the van, are the soldiers or policemen; while all the gentes camping on the left are associated with peace, though their first and second gentes, reckoning from the van, are policemen or soldiers. Among the Omaha both officers and warriors must be taken from the class of "young men," as the chiefs are afraid to act as leaders in war; and among both the Omaha and the Ponka the chiefs, being the civil and religious leaders of the people, can not serve as captains, or even as members, of an ordinary war party, though they may fight when the whole tribe engages in war. Among the Dakota, however, chiefs have led in time of war.
