The man who is capable of laughing heartily is not apt to be the one who carries some _conscience-stricken thought around with him_.

It is the easiest thing in the world to detect an untrue laugh.

The real laugh springs out of the depths of being and comes with a ringing sense of security and _faith in one's self_.

It goes with the workman in the early morning when he swings along the road to the factory.

It accompanies the soldier into battle.
