A better plan is to propose to make such races, school affairs. Offer to
plan with groups in any grade for small “stunts” as well as for the
larger affairs. Have it understood that the school will help even ten
boys to have a good time, on a suitable occasion. Put a bomb of
disapproval under gambling by men in connection with sports. Show
deepest disgust for the depraved natures of men who indulge in and
practice it.
Entirely out of connection with any school event, explain simply and
clearly why gambling is wrong. Be careful to make a clear distinction
between the play which is entirely right in itself and the betting or
gambling accompanying the play which is wholly wrong in principle.
