Knife  blades. 
a.  End  blades  for  men's  knives. — Among  the  rubbed  slate  blades 
I  have  definitely  classed  as  end  blades  for  men's  knives  only  those 
which  are  ( i )  slender  with  one  edge  straight  or  almost  so  and  the 
other  curved  inward  or  outward  (pi.  39,  figs.  14-17),  and  (2)  slender 
with  symmetrical  edges  but  too  long  to  have  been  suitable  for  harpoon 
blades  (pi.  39,  fig.  18).  All  seem  to  have  been  tanged  and  most  of 
them  have  a  median  ridge,  which,  however,  is  not  very  prominent. 
b.  Blades  for  ulus  or  n'onien's  knives. — The  ulu  blades,  30  in 
number,  are  all  of  rubbed  slate  (pi.  39,  figs.  23-25).  The  prevailing 
shape  is  oval  to  rectangular,  and  the  cutting  edge  is  either  curved  or 
straight.  Figure  2t,  is  unusual  in  shape,  being  very  high  and  with 
the  upper  edges  thickened  and  smoothed  where  ordinarily  they  would 
have  been  left  unfinished ;  the  smooth,  wide,  rounded  upper  end  sug- 
gests that  it  was  used  without  a  handle.  A  few  other  blades,  of  which 
figure  24  is  an  example,  have  two  cutting  edges,  and  these  also  may 
have  been  used  without  handles. 
Implements  with  rubbed  edges. — Under  this  heading  are  four  slate 
artifacts  of  unknown  use  (pi.  39,  figs.  19-22)  representing  a  type  of 
implement  which  does  not  appear  to  have  been  described  previously, 
although  the  smaller  end  is  suggestive  of  certain  "  drill  points  "  from 
Greenland  (Solberg,  1907,  pis.  5  and  6).  They  are  flat  pieces  of 
ground  slate,  with  one  straight  smoothed  edge  (the  left  as  shown  on 
the  plate)  about  3  mm  thick  and  3  to  3.5  cm  long.  The  tip  is  rubbed 
down,  leaving  a  short  upper  edge  7  mm  to  i  cm  long  which  joins  the 
longer  edge  either  at  a  right  angle  or  a  45°  angle.  Below  this  the  right 
edge  is  smoothed  in  a  similar  manner,  leaving  one  or  two  straight 
sections  (pi.  39.  figs.  19,  20)  or  a  somewhat  rounded  edge  (fig.  21, 
22).  The  function  of  such  implements  is  uncertain.  The  smoothed 
edges  could  well  have  resulted  from  their  use  as  rubbing  stones  but 
the  peculiar  shape  is  surely  intentional  and  suggests  that  they  had  a 
specific  use,  possibly  in  connection  with  the  dressing  of  skins,  or  as 
boot  sole  creasers. 
Drill  points. — Seven  stone  drill  points,  two  of  them  problematical, 
were  found  at  the  Hillside  site  ;  all  are  shown  in  plate  41.  figures  1-7. 
Two  are  of  ground  slate,  three  of  chipped  slate,  one  of  chert,  and  one 
of  quartz.  Plate  41,  figure  i,  is  a  four-sided  point  of  rubbed  slate,  the 
sides  of  which  taper  very  gradually  down  to  the  tip ;  the  tip  is  rubbed, 
producing  three  facets  and  one  short  sharp  cutting  edge.  Plate  41, 
figure  2,  is  a  natural  quartz  crystal,  columnar,  and  hexagonal  in  cross- 
section.  Its  use  as  a  drill  is  uncertain  ;  its  shape  is  perfectly  adapted  for 
the  purpose,  although  it  shows  no  certain  signs  of  wear.  Plate  41,
