Another  stream  flows  southwest  across  Sec.  15,  then  more  nearly
west  across  Sec.  22,  and  empties  into  Black  River  in  the  N.  E.  corner
of  Sec.  20.  This  is  the  largest  tributary  on  the  east  side  of  Black  River
in  the  part  of  the  country  where  the  party  worked,  and  only  Powder
Mill  Creek  on  the  west  side  exceeds  it  in  size.  The  stream  had  no
name  so  far  as  the  party  could  learn,  so  for  convenience  of  reference
it  will  be  spoken  of  here  as  ^^Sandstone  Creek,"  a  name  suggested  by
Dr.  Lane  from  the  fact  that  it  exposes  a  stratum  of  sandstone  in  Sec.
15.  When  it  enters  our  area  it  is  about  flfteen  feet  wide,  and  quite
rapid  since  just  there  it  is  flowing  over  bed  rock.  It  would  yield  some
power,  especially  in  the  west  part  of  Sec.  16,. T.  48  N.  Farther  down
it  is  not  so  rapid.    The  water  of  this  stream  also  is  dark.
Flowing  around  the  south  foot  of  Black  River  Highlands  is  another
stream  of  some  size.  Like  the  others  it  is  not  rapid  and  can  be  of  little
value  as  a  water  power.
A  stream  flows  around  the  north  side  of  the  Black  River  Highlands
but  it  is  smaller  than  that  which  flows  around  the  south  side.
Flowing  across  the  north  part  of  Sec.  27,  T.  49  N.  is  another  stream,
which  empties  into  Black  River  almost  at  the  line  between  Sees.  21  and
28,  and  about  800  paces  west.  The  stream  is  very  clear  since  it  carries
spring  water.  It  is  joined  near  the  mouth  by  a  stream  carrying  the
united  waters  of  several  small  spring  streams.  Sec.  28  is  very  much  cut
up  by  the  ravines  of  these  streams.
