justify it in a case where much feeling is shown, and there is a
liability to difficulty in preserving order. If the chairman has even
the appearance of being a partisan, he loses much of his ability to
control those who are on the opposite side of the question.* [The
unfortunate habit many chairmen have of constantly speaking upon
questions before the assembly, even interrupting the member who has the
floor, is unjustified by either the common parliamentary law, or the
practice of Congress. One who expects to take an active part in debate
should never accept the chair. "It is a general rule, in all
deliberative assemblies, that the presiding officer shall not
participate in the debate, or other proceedings, in any other capacity
than as such officer. He is only allowed, therefore, to state matters
of fact within his knowledge; to inform the assembly on points of order
or the course of proceeding, when called upon for that purpose, or when
he finds it necessary to do so; and on appeals from his decision on
questions of order, to address the assembly in debate." [Cushing's
Manual, page 106.] "Though the Speaker [chairman] may of right speak to
matters of order and be first heard, he is restrained from speaking on
any other subject except where the assembly have occasion for facts
within his knowledge; then he may, with their leave, state the matter of
fact." [Jefferson's Manual, sec. xvii, and Barclay's "Digest of the
Rules and Practice of the House of Representatives, U. S.," page 195.]]

never be forgotten, that, to control others, it is necessary to control
