disproved   the supposition that    students    should  be  scantily    fed.    O'Shea  claims  that
many    brain   workers are far short   of  their   highest grade   of  efficiency  because of
starving    their   brains  from    poor    diet.   And not only    must    the food    be  of  the right
quality,    but the body    must    be  in  good    health. Little  good    to  eat the best    of  food
unless  it  is  being   properly    digested    and assimilated.    And little  good    if  all the rest
is  as  it  should  be, and the right   amount  of  oxidation   does    not go  on  in  the brain
so  as  to  remove  the worn-out    cells   and make    place   for new ones.   This    warns   us
that    pure    air and a   strong  circulation are indispensable   to  the best    working of  our
brains. No  doubt   many    students    who find    their   work    too hard    for them    might
locate  the trouble in  their   stomachs    or  their   lungs   or  the food    they    eat,    rather  than
in  their   minds.
5. PROBLEMS FOR INTROSPECTION AND OBSERVATION
- Estimate    the mental  progress    made    by  the child   during  the first   five    years   and
 compare with that made during the second five years of its life. To do this make
 a list, so far as you are able, of the acquisitions of each period. What do you
 conclude as to the importance of play and freedom in early education? Why not
 continue this method instead of sending the child to school?
- Which   has the better  opportunity for sensory training,   the city    child   or  the
 country child? For social training? For motor development through play? It is
 said by specialists that country children are not as good players as city children.
 Why should this be the case?
- Observe carefully   some    group   of  children    for evidences   of  lack    of  sensory
 training (Interest in sensory objects, skill in observation, etc.). For lack of motor
 training (Failure in motor control, awkwardness, lack of skill in play, etc.). Do
 you find that general mental ability seems to be correlated with sensory and
 motor ability, or not?
- What    sensory training    can be  had from    (1) geography,  (2) agriculture,    (3)
 arithmetic, (4) drawing? What lines of motor training ought the school to afford,
 (1) in general, (2) for the hand, (3) in the grace and poise of carriage or bearing,
 (4) in any other line? Make observation tests of these points in one or more
 school rooms and report the results.
- Describe    what    you think   must    be  the type    of  mental  life    of  Helen   Keller.
