In  plate  42,  figures  17-19,  are  shown  three  smaller  implements  of 
greenish  prase,  with  four,  six,  and  four  faceted  edges,  respectively. 
Although  at  first  glance  these  might  appear  to  he  the  broken  ends 
of  scrapers  of  the  type  described  above,  the  arrangement  of  the  faceted 
surfaces  shows  that  they  were  used  just  as  they  are.  In  figure  18 
there  is  a  smooth,  perfectly  flat  lower  edge  12  mm  wide  and  36  mm 
long  at  right  angles  to  the  smoothed  part  of  the  outer  face.  The  smaller 
end  has  also  been  rubbed  down,  leaving  a  small  smoothed  surface

which  meets  the  other  two  at  right  angles  as  in  the  case  of  the  thin 
slate  forms  shown  in  plate  39,  figures  19-22.  Just  above  the  squared- 
ofif  end  is  a  fourth  smoothed  surface,  rubbed  down  to  a  45°  angle. 
Figure  17  is  generally  similar  in  shape,  but  the  faceted  surfaces, 
except  those  at  either  end,  are  not  perfectly  fiat  and  level ;  the  upper 
surface  is  slightly  concave  while  the  two  along  the  lower  end  are 
somewhat  rounded  or  convex.  Both  corners  are  squared  off,  and 
at  the  smaller  end  a  small  area  on  the  back  side  has  been  rubbed  down, 
making  in  all  six   faceted  surfaces.    Figure   19  has   four  smoothed
