Holford  islands,  lying  2  miles  NE.  by  N.  from  Foster  island,
consist  of  two  small  islands,  covered  with  trees,  the  tops  of  which  are
from  160  to  200  feet  above  the  water.  From  the  western  island  a
reef,  w^hich  uncovers  3  feet  at  low  water,  extends  i  mile  northwest-
ward, and  the  islands  in  this  direction  should  be  given  a  berth  of  1
mile.  Salmon  channel  is  between  Foster  island  and  Holford  islands,
in  which  a  mid-channel  course  should  be  kept.
Cullen  harbor,  on  the  south  side  of  Broughton  island,  at  the
entrance  to  Fife  sound,  extends  about  1,400  yards  in  a  northerly
direction.  Its  entrance,  between  Nelly  island  and  the  shore  west-
ward of  Gordon  point,  is  less  than  200  yards  wide,  and  when  enter-
ing care  should  be  taken  to  keep  exactly  in  mid-channel.  Inside
the  harbor  opens  out  to  600  yards  wide,  with  depths  of  from  4  to  8
fathoms.
At  the  head  of  the  harbor,  on  the  western  side,  a  narrow  boat  pas-
sage, through  which  the  tide  runs  with  great  strength,  leads  into
Booker  lagoon,  an  extensive  sheet  of  water  about  IJ  miles  in  extent,
with  depths  varying  from  12  to  more  than  45  fathoms.  This  lagoon
has  an  outlet  into  Queen  Charlotte  sound  to  the  westward  of  Long
island,  which  forms  the  western  side  of  Cullen  harbor.
