"I want to speak to you first of all as regards your duties as boys; and in the next place as regards your duties as men; and the two things hang together. The same qualities that make a decent boy make a decent man. They have different manifestations, but fundamentally they are the same. If a boy has not got pluck and honesty and common-sense he is a pretty poor creature; and he is a worse creature if he is a man and lacks any one of those three traits."
