the  Old  Bering  Sea  type,  if  we  may  judge  from  the  incomplete  speci- 
mens shown  in  plate  2i] ^  figures  i,  2.  It  seems  designed  for  the 
same  kind  of  grip,  however.  It  is,  on  the  whole,  very  similar  to  the 
old  Birnirk  (Point  Barrow)  throwing  board  (Mason,  1928,  pi.  i), 
even  though  it  might  not  have  been  cut  out  at  the  center  as  was  the 
latter. 
Spurs  for  the  end  of  tJie  throzving  board  (pi.  73,  fig.  17,  lev.,  cut  5, 
12  in.). — These  dififer  from  those  of  the  Old  Bering  Sea  period  in 
having  the  upper,  free  end  at  a  right  angle  to  the  tang.  In  addition 
to  the  specimen  illustrated  are  two  more  from  levoghiyoq,  12  and  22 
inches  deep,  and  one  from  Miyowagh,  cut  19,  5  inches  deep. 
Plate  yT,,  figure  18  (lev.,  cut  i,  50  in.),  is  an  ivory  peg  like  the 
one  shown  in  plate  ^^t,,  figure  25  ;  it  has  a  shallow  pit  in  the  upper  end  ; 
possibly  for  the  butt  end  of  the  dart  shaft. 
Wooden  mouthpieces  for  seal  skin  floats. — These  forms,  which  were 
common  at  Miyowagh,  were  represented  by  only  a  single  example,  a 
specimen  with  stopper  in  place,  found  at  levoghiyoq,  cut  5,  depth  33 
inches.  Plate  73,  figure  16  (lev.,  cut  9,  19  in.)  is  a  mouthpiece  of  this 
type,  but  made  of  ivory. 
Plate  y2if  figure  19  (lev.,  cut  5,  31  in.),  shows  the  Punuk  type  of 
wooden  plug  for  closing  holes  in  the  seal  skin  float.  It  is  very  different 
from  the  Old  Bering  Sea  type,  being  longer  but  of  smaller  diameter. 
Three  others  were  found  at  levoghiyoq,  at  depths  of  33  and  39  inches. 
Mouthpieces  for  bladder  floats. — The  present  evidence  suggests  that 
the  bladder  float  for  the  light  harpoon  may  not  have  been  known  to 
the  Old  Bering  Sea  Eskimos.  In  contrast  to  the  large  number  of 
wooden  mouthpieces  for  seal  skin  floats  which  were  found  at  Mi- 
yowagh, there  is  but  a  single  example  from  the  older  section  of  Mi- 
yowagh of  the  tubular  ivory  mouthpiece  or  nozzle  such  as  is  used  for 
inflating  the  bladder  float.  This  is  a  specimen  from  cut  27,  depth 
42  inches.  It  is  a  straight  tube,  with  the  center  sunken  and  roughened, 
leaving  a  rounded  projecting  rim  at  either  end.  Since  this  was  the 
only  ivory  mouthpiece  found  in  the  older  section  of  Miyowagh,  and 
since  it  comes  from  a  cut  which  adjoins  cut  19  where  much  early 
Punuk  material  was  found,  it  would  seem  permissible  to  regard  it 
as  of  early  Punuk  age.  The  four  other  tubular  mouthpieces  for  blad- 
der floats  found  at  Miyowagh  are  definitely  of  Punuk  age,  all  of 
them  coming  from  the  later,  northwestern  section  of  the  midden.  One 
of  these  is  the  specimen  shown  on  plate  'J2)y  figure  11,  from  cut  4, 
depth  20  inches.  It  has  the  "  cannon  "  shape  of  the  modern  Alaskan 
examples  (Nelson,  pi.  56).  The  forward  end,  which  was  inserted 
in  the  bladder,  is  cut  down ;  it  is  also  roughened  and  has  a  slight  lip
