NO.    I  ARCHEOLOGY    OF    ST.    LAWRENCE    ISLAND— COLLINS  101 
The  third,  fragmentary,  head  of  this  type,  from  the  upper  level  of 
the  midden,  is  decorated  in  the  same  style. 
From  Miyowagh  there  is  a  single  fragmentary  example,  undecor- 
ated,  from  cut  i8,  depth  53  inches;  and  an  unfinished  specimen  from 
cut  27,  depth  44  inches,  (From  cut  7,  48  in.  deep,  there  is  the  lower 
end  of  a  harpoon  head  with  Old  Bering  Sea  decoration  that  is  unique 
in  having  the  line  hole  (originally  two  ?)  in  the  plane  of  the  spur.  The 
latter  is  tri furcated  and  symmetrical,  the  socket  wide  and  deep  with 
two  lashing  slots.  This  is  the  only  instance  I  have  seen  of  a  sym- 
metrical trifurcated  spur  which  was  not  at  right  angles  to  the  line 
hole  or  holes.) 
Open  socket  type  I  y. — Same  as  above  except  that  it  is  a  flattened 
oval  in  cross-section,  and  has  the  side  blades  at  right  angles  to  the 
line  holes;  decorated  (Old  Bering  Sea)  or  plain.  (PI.  23,  fig.  3; 
pis.  24  and  25,  figs,  i,  2;  pi.  25  shows  the  socket  side  of  the  same 
harpoon  heads  figured  on  pi.  24.) 
Three  harpoon  heads  of  this  type  have  been  described  previously, 
one  by  Wissler  from  Cape  Smythe  near  Point  Barrow,  one  by  Jenness 
from  Little  Diomede  Island,  one  by  Mathiassen  from  northern  Alaska 
(Wissler,  1916,  p.  410;  Jenness,  1928  b,  fig.  3,  c;  Mathiassen,  1929, 
fig.  13,  b.). 
No  finished  examples  were  found  at  the  Hillside  site — only  the  un- 
finished one  shown  in  plate  23,  figure  3,  from  the  second  level  of  the 
midden,  and  one  other  from  among  the  rocks  at  the  south  end.  The 
beginning  of  the  groove  into  which  the  two  line  holes  would  have 
opened  is  visible  on  the  side  opposite  the  socket ;  on  the  opposite  side 
the  lower  end  has  been  slightly  hollowed  and  beveled  in  preparation 
for  a  trifurcated  spur. 
From  Miyowagh  there  are  three  specimens  (pi.  24,  figs.  1,2)  and 
an  undecorated  fragment,  from  cut  18,  depth  72  inches.  Plate  24, 
figure  I  (cut  7,  depth  75  in.),  is  almost  straight-sided  with  a  rather 
wide,  blunt  end  ;  the  side  opposite  the  socket  is  almost  flat,  whereas 
in  the  other  known  examples  it  is  gracefully  rounded.  The  side  blades, 
of  chipped  slate,  are  also  placed  nearer  the  tip  than  is  customary.  Plate 
24,  figure  2  (cut  2^,  depth  65  in.),  is  undecorated  and  small — only  6.6 
cm  long;  the  blades  are  of  chipped  jasper;  the  groove  at  the  lower 
end  was  for  a  lashing  which  was  applied  after  a  split  occurred  between 
the  central  spur  and  lower  line  hole. 
Open  socket  type  I  (a)  y. — Same  as  type  I  y  except  that  there  are 
two  pairs  of  small  barbs,  at  right  angles  to  the  line  holes,  in  addition 
to  the  side  blades.    (PI.  24,  fig.  3.)
