Among Atsugewi all mourners had to deny themselves meat and fresh fish for one day; then they sweated and swam after the funeral. Mountain Maidu mourners, including all persons who had had any part in the funeral, had to undergo four or five days taboo on eating all flesh. They also had to eat alone and from separate dishes, do head scratching with special sticks only, were allowed no hunting, gambling, intercourse, or smoking. Purification of those persons contaminated by participation in burial included swimming and washing every day that the taboos were in effect.

Only Atsugewi, of all local tribes, are said to have practiced suicide, though unquestionably it did occur on occasion among all California Indians.

Mentioning the name of the deceased in the presence of his relatives was considered very poor taste, and was actually forbidden in some cases.

It was forbidden that the widow touch the corpse, so that relatives had to prepare the body for burial. After the funeral, the widow always cut her hair off closely. If an Atsugewi, she made a belt out of it, and the hair belt was then often decorated with shells. In all local tribes the widow traditionally covered her whole head and face with pitch and covered this with white diatomaceous earth or black charcoal. Touching her head or face (the whole body for mountain Maidu) with fingers was taboo; she could do this only with the scratching stick which mountain Maidu widows wore around the neck. Raggedy, ill-looking clothes were worn by the survivor, and Atsugewi widows put pitch on old basketry caps to be worn. A mourning necklace was worn at all times, made of lumps of hard pitch strung onto a fiber string. This was worn until remarriage, which was usually two or three years for Atsugewi and one to three years for mountain Maidu. Pitch on the face and head was normally left on until it wore off of its own accord.

The mourning conduct of grieving men who had lost their wives in death was not nearly so lengthy or as rigorous as was that of widows. Widowers cut their hair too, but among Atsugewi the only other observance required was abstinence of flesh eating for a day. Mountain Maidu widowers spent one sleepless night out in the mountains. Widowers did not generally sing at dances and at “big times” for about a year, but this was not compulsory. The Yana are said to have stayed away from dances for two or three years.
