and  the  relation  of  line  hole  and  blade  by  the  letters  x  and  y,  the 
former  indicating  that  the  line  hole  and  blade  are  parallel,  the  latter 
that  they  are  at  right  angles.  The  types  in  each  group  that  are  de- 
scribed first  are  those  which  were  found  only  at  the  Hillside  site  or 
in  the  southeastern  section  of  the  next  site,  Miyowagh ;  these  are, 
therefore,  the  Old  Bering  Sea  types.  Following  these  are  the  few 
early  Punuk  types,  found  mainly  at  the  later,  northwestern  section 
of  Miyowagh.  Later,  as  we  describe  the  material  from  levoghiyoq, 
Seklowaghyaget,  and  the  recently  abandoned  ruins  adjoining  the 
present  village  of  Gambell,  the  sequence  will  be  continued  to  include 
the  various  Punuk,  protohistoric,  and  modern  types. 
The  distribution  of  the  various  types  of  harpoon  heads  according 
to  depth  and  site  is  given  in  table  2  (p.  216).  Text  figure  24  (p.  216) 
is  a  graphic  arrangement  of  the  principal  open  socket  harpoon  types  at 
Gambell,  showing  developmental  stages  from  Old  Bering  Sea  to 
modern  times. 
Open  Socket  Harpoon  Heads 
Open  socket  type  I  x. — Two  lashing  slots ;  at  proximal  end  a  sym- 
metrical median  spur,  tri  furcated,  with  center  prong  longer  than  the 
two  adjoining;  two  line  holes,  one  above  and  one  below  the  socket, 
connected  on  the  side  opposite  the  socket  by  a  deep  groove  into  which 
the  lashing  slots  open ;  two  deep,  narrow  pits  or  sockets,  parallel  with 
the  line  holes,  for  holding  the  stone  side  blades ;  no  end  blade ;  oval 
to  almost  round  in  cross-section;  decorated  (Old  Bering  Sea)  or 
plain.    (PI.  23,  figs.  I,  2  and  text  fig.  24.) 
Two  harpoon  heads  of  this  type  have  been  described  previously, 
one  by  Jenness  from  Little  Diomede  Island  and  one  by  the  writer 
from  northern  Alaska,  exact  locality  unknown  (Jenness,  1928  a,  pi. 
13,  a;  Collins,  1929,  pi.  2,  / — the  blade  slots  and  one  of  the  line  holes 
incomplete). 
Three  examples  were  found  at  the  Hillside  site,  two  of  which  are 
illustrated  in  plate  23,  figures  i,  2;  both  were  found  among  the  rocks 
at  the  south  end.  Plate  23,  figure  i,  is  complete  except  for  the  tip; 
the  thin  partition  between  the  blade  sockets  has  broken  through.  The 
two  line  holes  are  drilled  at  an  angle,  converging  slightly  as  they  enter 
the  deep  connecting  groove  on  the  back  side.  The  lower  end  just 
below  the  socket  has  been  hollowed  out  smoothly  to  a  depth  and  width 
that  exactly  fits  the  end  of  one's  thumb.  The  lower  end  of  plate  23, 
figure  2,  is  broken  and  the  upper  end  has  been  reworked  into  a  drill 
or  reamer;  the  side  blades  of  jasper,  parallel  with  the  line  holes,  are 
still  firmly  in  place.  The  decoration,  as  in  figure  i,  is  Old  Bering  Sea.
