The clan had the right to adopt into it any outsider it pleased, and this right of adoption was frequently exercised. In this manner white, or other prisoners, or friends, were incorporated into the clan and therefore into the tribe, taking the place perhaps of some deceased son or brother, daughter or sister. The adopted men not infrequently rose to positions of importance, even to that of head chief. These officers were usually chosen because of personal qualifications and achievements, but it was not uncommon for the title of ordinary chief to be bestowed on a visitor as a sort of honorary degree. There were many chiefs of varying power and importance, mostly military; the office of sachem, a purely civil position, was more difficult to attain, as it was generally hereditary within the clan. Because of the law of maternal descent, a man's son in most tribes could not inherit his father's office. He might be adopted, however, by the clan.
