These voluntary associations are not of necessity ancient or permanent. An instance is given in Fig. 738 which is instructive in the interpretation of pictographs. It is a copy of drawings on a pipe stem which had been made and used by Ottawa Indians. On each side are four spaces, upon each of which are various incised characters, three spaces on one side being reserved for the delineation of human figures, each having diverging lines from the head upward, denoting their social status as chiefs or warriors and medicine men.
Fig. 738.—Ottawa pipe stem.
Upon the space nearest the mouth is the drawing of a fire, the flames passing upward from the horizontal surface beneath them. The cross bands are raised portions of the wood (ash) of which the pipestem is made; these show peculiarly shaped openings which pass entirely through the stem, though not interfering with the tube necessary for the passage of the smoke. This indicates considerable mechanical skill.
Upon each side of the stem are spaces corresponding in length and position to those upon the opposite side. In the lower space of the stem is a drawing of a bear, indicating that the two persons in the corresponding space on the opposite side belong to the bear gens. The next upper figure is that of a beaver, showing the three human figures to belong to the beaver gens, while the next to this, the eagle, means that the opposite persons are members of the eagle gens. The upper figure is that of a lodge which contains a council fire, shown on the opposite side.
The signification of the whole is that two members of the bear gens, three members of the beaver gens, and three members of the eagle gens have united and constitute a society living in one lodge, around one fire, and smoke through the same pipe.
Reference may also be made to remarks by Prof. Dall (d) upon the use of masks by associations or special classes.
