NO,    I  ARCHEOLOGY    OF    ST.    LAWRENCE    ISLAND — COLLINS  211 
The  line  hole  is  large  and  squarish.  Except  for  the  direction  of  the 
blade  slit,  this  specimen  conforms  in  every  way  with  type  III  (b)  x. 
Open  socket  type  III  (c)  x. — Differs  from  type  III  (b)  x  in  having 
a  pair  of  small  barbs  in  addition  to  an  end  blade.    (PI.  71,  figure  11.) 
The  specimen  illustrated,  from  cut  2,  depth  22  inches,  is  the  only 
example  of  this  type.  Part  of  the  upper  end  is  broken  ofif,  and  also  a 
small  piece  at  the  socket. 
Open  socket  type  IV  (a). — -One  lashing  slot  and  an  opposite  groove  ; 
wedge-shaped  socket,  as  in  type  III  (b)  x;  single  (?)  lateral  spur; 
triangular  line  hole ;  two  pairs  of  prominent  barbs,  at  right  angles  to 
line  hole  ;  no  blade  ;  undecorated.    (PI.  71,  fig.  i.) 
The  specimen  illustrated,  from  cut  2,  depth  22  inches,  was  the  only 
one  found.  It  is  another  western  variant  of  the  Thule  type  2  head. 
The  triangular  line  hole,  the  bladeless  tip,  and  probably  the  spur  are 
features  which  correspond  with  our  type  IV;  the  two  pairs  of  barbs 
are  like  type  IV  (a)  x.  The  peculiar  form  of  the  socket,  however, 
l)rings  it  into  relationship  with  type  III  (b)  x.  The  spur  is  damaged, 
so  its  exact  form  must  remain  in  doubt ;  however,  it  was  placed  later- 
ally, and  very  likely  was  single.  The  deep,  narrow  groove  above  the 
line  hole  is  like  that  in  plate  70,  figure  6. 
Open  socket  type  V. — Two  lashing  slots,  one  lashing  slot  with  an 
opposite  groove,  or  a  groove  alone;  socket  and  spur  as  in  Type  III 
(b)  x;  line  hole  triangular,  rarely  round;  no  blade;  undecorated. 
(PI.  71,  figs.  12,  13.) 
Three  examples  of  this  type  were  found  at  Seklowaghyaget,  the  two 
illustrated,  from  cuts  2  and  7,  depths  18  atid  12  inches  respectively, 
and  another  picked  up  on  the  surface. 
In  its  general  shape  and  lack  of  an  inserted  blade,  this  tyi^e  conforms 
to  Mathiassen's  Thule  type  i,  but  the  peculiar  wedge-shaped  socket 
and  beveled  spur  relate  it  to  our  types  III  (b)  x  and  y. 
Closed  Socket  Harpoon  Heads 
Only  seven  harpoon  heads  with  closed  sockets  (exclusive  of  those 
used  in  whaling)  were  found  at  Seklowaghyaget. 
Closed  socket  type  V  y. — Defined  on  page  iii.  Only  two  of  this 
type  w'ere  found,  an  unfinished  specimen  from  cut  3,  depth  62  inches, 
and  a  smoothed,  waterworn  specimen  from  cut  6,  depth  28  inches. 
This  was  a  type  which  apparently  passed  out  of  use  soon  after  Sek- 
lowaghyaget was  established. 
Closed  socket  type  V  (a)  y. — Defined  on  page  207  (pi.  71,  fig.  14). 
There  are  three  specimens  of  this  type,  as  follows:  Cut  3,  depth  30 
inches ;  cut  4,  depth  12  inches  (pi.  71,  fig.  14)  ;  cut  8,  depth  60  inches.
