tribe into twohalveswhen playing ceremonial lacrosse is character- 
istic not only of the Winnebago, but of the Omaha, Menominee, 
Sauk, Fox, and other tribes. Among the former two, these sides 
are identical with the two aforementioned political divisions 
of the tribe, but among the latter two, where no such division 
exists, the tribe seems to divide itself into two halves merely 
on this occasion, although we know that this is not the only 
occasion upon which it behaves in this manner. 
Up to the present, we have treated the two divisions as 
social units per se , but now, before entering on the discussion 
of the clans, it may be well to point out the fact that the warjgeregi 
people are sometimes spoken of as the Bird clan (■ wamyk * hoki~ 
k'aradjdra ) , and that the four clans composing this side are so 
intimately related, and their clan origin myths so similar, one 
of them even declaring the other three bird clans to be merely 
the descendants of the three younger thunderbird ancestors, 
that the assumption of the four clans representing one clan 
that became split up into a number of divisions, is not 
outside the realm of historical possibility. This is, however, 
quite immaterial, for whether we have one bird clan opposed to 
eight other animal clans is of little consequence, since historically 
it is not the bird clan that is opposing the other clans, but one 
social unit, the division, set off against another. The numerical 
equality that exists between these two sides, in spite of the 
disparity in the number of clans, is perhaps another confirmation 
of the fundamental character of the twofold structure. 
THE CLAN ORGANIZATION. 
There are twelve clans (hokik'aradjora) among the Winne- 
bago: the Thunderbird (wak-andja ) , the Warrior ( wonayere wayk- 
cf£'),the Eagle (tcaxcep *), and Pigeon (ru-tcge), now extinct, belong- 
ing to the warjgeregi half; and the Bear ( hurjk'), Wolf ( cuyktcuyk *), 
Buffalo ( tee ), Water-spirit ( wakteexi ), Deer (tear), Elk ( huwq ), 
Snake ( wak'q ), and Fish (ho'), all belonging to the mqnegi half. 
In addition to the above names, we have the name Chief 
(huyk) applied to the Thunderbird; Hawk ( keretcy ), to the 
Warrior; ( manype ) Soldier, to the Bear clans.
