of handling a specimen so as to describe the technique. 
360. To strain the pounded cassava the sifter is either rested be- 
tween the forks of the big toes, over the extended and open legs, 
between which it falls onto a mat placed below (pl. 74 A), or else

baking ovens. The present-day Taruma, Waiwai, and Parikuta 
also use them (JO). They may sometimes be seen chipped more or 
less roughly into circles of from 12 to 18 inches diameter. There 
are several references in the literature to the old-time use of flat 
stones for the cassava grids (St, 1, 388; BA, 278; Cr, 119).
