Speak seldom, but to important subjects, except such as particularly relate to your constituents, and, in the former case, make yourself perfectly master of the subject.
Speak not injurious words, neither in jest nor earnest. Scoff at none though they give occasion.
Sleep not when others speak, sit not when others stand, speak not when you should hold your peace, walk not when others stop.
Facts may speak for themselves.
Always speak the truth.
Speak not evil of the absent for it is unjust.
