 Dear Son,

   I kNOw that astroNOmy, ecoNOmics,and

oceaNOgraphy are eNOugh to keep even an

hoNOr student buzy. Do NOt forget that the

pursuit of kNOwledge is a NOble task, and you

can never study eNOugh.

Love,                                 

Dad

Do you find the secret between the letters,

my dear friends.
