slightly inclined from the ver-
tical and set on edge, the
work at this point resembled
the laying of an ordinary
vertical circular wall. As
the work advanced exterior
scaffolds were built up almost
vertically but following the
angle, until the overhang
reached a stage where the
surface had become flat
enough for men to work on
it directly. From this point

on the incomplete arching
shell of tile, reaching over
the edge of the last course
to lay.
