Theprocess of jicelingosiers by a cleft stickis shown at Komna,Thebes. The usesof the osier amongthe ancient Egyp-tians were constantand various. Bas-kets were even morecommon then thannow, as the jiroductsof the lield, the net,and tile hook were generally carried by men. The wheeled vehicles inEgypt were few and not capacious. Machines for ))eeling osiers proceed in variousways. In Colbys, the osier wands are carried be-tween vulcanized rubber rcjUers which press, rub,and wring the bark from the wood. A serratedmetallic roller acts in connection with an elas-tic or yielding roller, both having an end chaseor lateral reciprocation to rub otl the bark of thewand. A rack or comb
