The following descriptions of shield-designs are given with the interpretations of their owners. A shield-cover decorated with feathers, bearing a design used by a chief on ceremonial occasions, and said by him to be the copy of a shield carried in his youth, is shown in Plate V. The black border on top of the shield takes the form of the new moon, which it represents. In the centre of the shield is a well executed drawing of an Indian on horseback. The horse is in blue, with zigzag black lines extending down the legs. The blue color of the horse indicates his connection with the thunder, or the powers of the sky. The background of the shield is in yellow, but the lower part has been worked over with green. Symmetrically arranged around the mounted figure are four circles of purplish color, representing a phenomenon observed in the sky, which seems to have been either the halo of the sun, or the phenomenon that passes under the name of “sun-dogs.” From the description of the owner of the shield, it appears that these four circles were associated in his mind with the medicine-hoop. He stated that this design as a whole was the representation of what he saw in a dream; that the moon with its dark color was drawn to represent the night, because that was the time when he had this experience; and that in the dream he saw a horse and rider appear in the sky surrounded by the four circular objects, as indicated upon the shield. It appears from his explanation, that the association of the rings with the medicine-hoop was his own individual interpretation of the significance of his dream. In the dream he could see a shield associated with these objects as they would appear in reality; but in the design he attempted to convey an idea of what he saw in conformity with the conventional modes of representative art practised by his tribe.
