I have no objection to a little exuberance in the young learner. Nay, I would urge teachers too like nurses to be careful to provide softer food for still undeveloped minds and to suffer them to take their fill of the milk of the more attractive studies. For the time being the body may be somewhat plump, but maturer years will reduce it to a sparer habit.
Such plumpness gives hope of strength; a child fully formed in every limb is likely to grow up a puny weakling. The young should be more daring and inventive and should rejoice in their inventions, even though correctness and severity are still to be acquired. Exuberance is easily remedied, but barrenness is incurable, be your efforts what they may.
