Harpoon  Heads  from  Ievoghiyoq 
From  Ievoghiyoq  there  are  133  harpoon  heads  sufficiently  complete 
for  type  identification,  in  addition  to  a  number  of  fragments  and  un- 
finished specimens. 
Open  Socket  Harpoon  Heads 
Open  socket  type  II  (b)  x. — Two  lashing  slots;  bifurcated,  sym- 
metrical (median)  spur;  round  line  hole  ;  two^  side  blades  parallel  with 
the  line  hole  (pi.  70,  fig.  i.) 
A  comparatively  unimportant  type,  represented  by  the  single  speci- 
men shown  in  plate  70,  figure  i,  from  cut  i,  depth  12  inches.  The  spur, 
although  broken,  was  symmetrical  like  that  of  plate  28,  figure  5.  The 
side  blades  had  been  inserted  in  a  slot  which  passes  through  from  one 
side  to  the  other ;  no  end  blade. 
Open  socket  type  II  (b)  y. — Same  as  above  except  that  the  side 
blades  are  at  right  angles  to  the  line  hole  and  that  the  latter  may  be 
triangular  in  shape  (pi.  70,  fig.  2). 
This  type  is  also  represented  by  the  single  specimen  illustrated, 
from  cut  5,  depth  18  inches.  The  material  is  bone,  and  the  remaining 
side  blade  is  made  of  shell;  the  line  hole  is  triangular.  From  cut  5, 
depth  50  inches,  there  is  the  upper  end  of  a  head  corresponding  to  this, 
but  made  of  ivory  and  with  a  round  line  hole. 
Open  socket  type  II  (c)  x. — Two  lashing  slots;  a  single,  lateral 
spur;  triangular  line  hole;  two  side  blades,  parallel  with  the  line  hole 
(pi.  70,  fig.  3)- 
The  specimen  illustrated,  from  cut  i,  depth  22  inches,  is  the  only 
example  of  the  type.  It  is  of  bone  and  the  side  blades  were  of  shell ; 
the  latter  were  set  in  a  slot  which  passes  completely  through  from  one 
side  to  the  other. 
Open  socket  type  II  {c)  y. — Same  as  above  but  with  the  side  blades 
at  right  angles  to  the  line  hole ;  the  latter  is  round. 
Two  examples,  both  fragmentary  and  of  bone,  from  cut  i,  depth 
28  inches,  and  cut  9,  34  inches. 
Open  socket  type  III  (a)  x. — Defined  on  page  118.  (PI.  70,  figs. 
8-15).  This,  the  dominant  form  of  harpoon  head  at  Ievoghiyoq,  is 
represented  by  98  specimens,  distributed  as  follows:  Cut  i,  depth  12 
inches  (4)  ;  22  inches;  28  inches;  31  inches;  34  inches;  40  inches; 
44  inches  (2).  Cut  2,  16  inches ;  30  inches ;  37  inches.  Cut  3,  12  inches. 
Cut  4,  42  inches  (2)  ;  59  inches  (2)  (pi.  70,  fig.  8).  Cut  5,  12  inches 
(12)  ;  18  inches  (3)  ;  24  inches  (2)  ;  28  inches  (2)  ;  31  inches  (4)  ; 
33  inches  (2)   (pi.  63,  fig.  10)  ;  39  inches  (4).    Cut  6,  5  inches  (6)
