occasionally,  because  it  is  traveling  at  an  angle
with  the  direction  of  the  movement  of  the  plow.
The  rear  furrow-wheel  is  usually  turned  out  a  lit-
tle from  the  unplowed  land  or,  as  it  is  generally
stated,  is  given  a  small  amount  of  "  lead"  from  the
land.  The  wheel  should  also  set  an  inch  or  so  out-
side of  the  line  of  the  landside  so  as  to  remove  the
friction  on  this  part  as  much  as  possible.  The  front
furrow- wheel  is  given  "lead"  from  the  land  with
the  single  plow  and  toward  the  land  when  the  team
b  hitched  abreast  on  gangs.  The  change  is  made
in  the  latter  case  because  the  line  of  draft  is  out-
aide  of  the  line  of  work,  and  hence  the  front  fur-
row-wheel is  turned  in  to  hold  the  plow  out  to  its
work  and  make  it  travel  directly  to  the  front.
