In Australia, where dancing is carried to a high pitch of elaboration, its association with the sexual impulse is close and unmistakable. Thus, Mr. Samuel Gason (of whom it has been said that "no man living has been more among blacks or knows more of their ways") remarks concerning a dance of the Dieyerie tribe: "This dance men and women only take part in, in regular form and position, keeping splendid time to the rattle of the beat of two boomerangs; some of the women keep time by clapping their hands between their thighs; promiscuous sexual intercourse follows after the dance; jealousy is forbidden." Again, at the Mobierrie, or rat-harvest, "many weeks' preparation before the dance comes off; no quarreling is allowed; promiscuous sexual intercourse during the ceremony." The fact that jealousy is forbidden at these festivals clearly indicates that sexual intercourse is a recognized and probably essential element in the ceremonies. This is further emphasized by the fact that at other festivals open sexual intercourse is not allowed. Thus, at the Mindarie, or dance at a peace festival (when a number of tribes comes together), "there is great rejoicing at the coming festival, which is generally held at the full of the moon, and kept up all night. The men are artistically decorated with down and feathers, with all kinds of designs. The down and feathers are stuck on their bodies with blood freshly taken from their penis; they are also nicely painted with various colors; tufts of boughs are tied on their ankles to make a noise while dancing. Promiscuous sexual intercourse is carried on _secretly_; many quarrels occur at this time." (_Journal of the Anthropological Institute_, vol. xxiv, November, 1894, p. 174.)
