"The fact that they did not circumcise also suggests that they would have interacted more closely with their northern and southern neighbours in ritual practice than they did with the Wajarri to the east, despite the indications that their relations with the Wajarri were better than for most coastal groups."

"Among the Angaardies, circumcision is performed by of a sharp flint, and after the consummation of the rite, the youth is forbidden to look on a woman for the space of two years, consequently he cannot associate with the rest of the tribe, except with the men when hunting, the women then being about their own business. When this time of probation past, he comes near the general camping-place, makes a good fire, and all his friends go to see him, felicitating him on the termination of his solitary mode of life, and if there be any female whom he has legal claims, she is at once surrendered."
