…the members of the assembly should unitedly elect a chairman and lay down guide-lines and by-laws for their meetings and discussions. The chairman should have charge of such rules and regulations and protect and enforce them; the other members should be submissive, and refrain from conversing on superfluous and extraneous matters.
