The  business  of  the  teacher  is  to  instruct,  drill,  and  test.  The  instruc-
tion ought  to  be  clean  cut  and  thorough.  Then  drill  to  acquire  power
and  skill.  It  is  not  enough  that  a  student  be  led  to  see  a  truth,  but  he
must  acquire  the  power  to  see  this  truth  quickly  and  easily.  We  should
drill  our  classes  on  the  instruction  given  to  make  it  a  i)ermanent  posses-
sion. Require  our  students  to  solve  many  original  exercises,  also  to  pre-
pare problems  to  be  solved  by  the  class.  In  giving  these  drills  we  should
ke<^p  in  mind  the  weak  students  as  well  as  the  strong  ones.  Continue
this  exercise  until  accurate  results  are  obtained  quickly.
The  Test, — The  third  exercise  in  teaching  is  tlie  testing  of  results  of
instruction  and  learning.  What  tests  sihall  we  apply?  The  oral  and
written.
The  Oral  Test, — The  first  work  to  be  done  in  a  recitation  is  to  determine
whether  the  instruction  given  the  previous  day  is  fully  comprehended.
We  should  do  this  as  a  check  on  our  teaching.  It  will  not  do  to  pass  on
without  this  test.  It  is  our  duty  to  know  the  progress  made  thus  far.
