Still, all our pupils will require some relaxation, not merely because
 there is nothing in this world that can stand continued strain and even
 unthinking and inanimate objects are unable to maintain their strength,
 unless given intervals of rest, but because study depends on the good
 will of the student, a quality that cannot be secured by compulsion.
 Consequently if restored and refreshed by a holiday 
 they will bring greater energy to their learning and approach their work
 with greater spirit of a kind that will not submit to be driven. I approve of play in the young; it is a sign of a lively disposition;
 nor will you ever lead me to believe that a boy who is gloomy and in a
 continual state of depression is ever likely to show alertness of mind
 in his work, lacking as he does the impulse most natural to boys of his
 age.
