the seven principal gentes of the tribe is represented by one of these 
mystic arrows, which are used to foretell what will happen, good or 
evil, to each gens during the year following the ceremony. These 
divining arrows also stand for the continuity of each gens through 
its natural increase. ‘The members of the gens to whom is entrusted 
the keeping of these sacred articles are privileged to name their sons, 
“ Mo”’-pi-zhi,” Bad Arrow; this name has been seldom used. The 
word “ pi-zhi” or bad, is not used here in its ordinary sense, but 
refers to the mysterious characters of the divining arrow.
