The  result  fully  justified  the  expense,  for  in  the  remaining
seven  years  he  made,  over  and  above  all  expenses,  money
enough  to  pay  $12,000  for  the  farm  he  had  drained.  No
land  can  produce  well  without  the  aid  of  heat  and  proper
aeration.  If  the  soil  is  full  of  water  it  will  be  impervious
to  the  air,  and  the  water  will  also  counteract  the  effects  of
the  sun's  rays,  and  the  ground  will  be  cold  and  lifeless.
