FIGURES OF CIRCLES AND RAYS PROBABLY REPRESENTING SUN SYMBOLS. Tenth Annual Report of the Bureau of Ethnology, figs. 1118-1121, 1123.] Rev. John McLain, in his work on the "Blackfoot Sun-dance," says: On the sacred pole of the sun lodge of the Blood Indian is a bundle of small brushwood taken from the birch tree, which is placed in the form of a cross. This was an ancient symbol evidently referring to the four winds. [Illustration: Fig. 317. FIGURES OF CROSSES AND CIRCLES REPRESENTING STAR SYMBOLS. Oakley Springs, Ariz.

Tenth Annual Report of the Bureau of Ethnology, fig. 1203.] _Sun and star symbols._--Great speculation has been made, both in Europe and America, over the relation between the Swastika and the sun, because the two signs have been associated by primitive peoples. Colonel Mallery gives the Indian signs for the sun, stars, and light.[287] These have been segregated, and it will be seen that the cross and circle are used indiscriminately for one and the other, and the fact of the two being found associated is no evidence of relationship in religious ideas (figs. 315-319). _Dwellings._--Among the Hidatsa, the cross and the circle represent neither the sun nor any religious ideas, but merely lodges, houses, or dwellings. The crosses in fig. 319 represent Dakota lodges; the small circles signify earth lodges, the points representing the supporting poles. Buildings erected by civilized people were represented by small rectangular figures, while the circles with dots in a square represent earth lodges, the home of the Hidatsa. [Illustration: Fig. 320.
