"Tibetan women are robust and the men weak, and one may frequently see women performing in the place of their husbands the socage services which the people owe. As a consequence (of the superior physique of the women), three or four brothers sometimes marry one wife, and if children are born to them, they take their choice of them and divide them among themselves. The woman who is able to live with three or four brothers is called by every one 'a belle', because she knows how to manage a whole family." (p. 230)
