The agate beads had first been severed from the parent nodule by sawing and then by splitting. The shaping of barrel-cylinder type was carried out entirely by careful flaking. When all depressions and irregularities had been smoothed away by grinding, the object was then polished. Before this final finish took place, the bead had to be bored, a process that was carried out from both ends by means of drill. (MCK, 210-11)
