VI. If the witness determine to be witty or refractory with you, you had better settle that account with him at first, or its items will increase with the examination. Let him have an opportunity of satisfying himself either that he has mistaken your power, or his own. But in any result, be careful that you do not lose your temper; anger is always either the precursor or evidence of assured defeat in every intellectual conflict.
VII. Like a skilful chess-player, in every move, fix your mind upon the combinations and relations of the game—partial and temporary success may otherwise end in total and remediless defeat.
VIII. Never undervalue your adversary, but stand steadily upon your guard; a random blow may be just as fatal as though it were directed by the most consummate skill; the negligence of one often cures, and sometimes renders effective, the blunders of another.
IX. Be respectful to the court and to the jury; kind to your colleague; civil to your antagonist; but never sacrifice the slightest principle of duty to an overweening deference toward either.
In "The Advocate, his Training, Practice, Rights, and Duties," written by Cox, and published in England about a half century ago, there is an excellent chapter on cross-examination, to which the writer is indebted for many suggestions. Cox closes his chapter with this final admonition to the students, to whom his book is evidently addressed:—
"In concluding these remarks on cross-examination, the rarest, the most useful, and the most difficult to be acquired of the accomplishments of the advocate, we would again urge upon your attention the importance of calm discretion. In addressing a jury you may sometimes talk without having anything to say, and no harm will come of it. But in cross-examination every question that does not advance your cause injures it. If you have not a definite object to attain, dismiss the witness without a word. There are no harmless questions here; the most apparently unimportant may bring destruction or victory. If the summit of the orator's art has been rightly defined to consist in knowing when to sit down, that of an advocate may be described as knowing when to keep his seat. Very little experience in our courts will teach you this lesson, for every day will show to your observant eye instances of self-destruction brought about by imprudent cross-examination. Fear not that your discreet reserve may be mistaken for carelessness or want of self-reliance. The true motive will soon be seen and approved. Your critics are lawyers, who know well the value of discretion in an advocate; and how indiscretion in cross-examination cannot be compensated by any amount of ability in other duties. The attorneys are sure to discover the prudence that governs your tongue. Even if the wisdom of your abstinence be not apparent at the moment, it will be recognized in the result. Your fame may be of slower growth than that of the talker, but it will be larger and more enduring."
