First, as to your own witnesses.

I. If they are bold, and may injure your cause by pertness or forwardness, observe a gravity and ceremony of manner toward them which may be calculated to repress their assurance.

II. If they are alarmed or diffident, and their thoughts are evidently scattered, commence your examination with matters of a familiar character, remotely connected with the subject of their alarm, or the matter in issue; as, for instance,—Where do you live? Do you know the parties? How long have you known them? etc. And when you have restored them to their composure, and the mind has regained its equilibrium, proceed to the more essential features of the case, being careful to be mild and distinct in your approaches, lest you may again trouble the fountain from which you are to drink.

III. If the evidence of your own witnesses be unfavorable to you (which should always be carefully guarded against), exhibit no want of composure; for there are many minds that form opinions of the nature or character of testimony chiefly from the effect which it may appear to produce upon the counsel.

IV. If you perceive that the mind of the witness is imbued with prejudices against your client, hope but little from such a quarter—unless there be some facts which are essential to your client's protection, and which that witness alone can prove, either do not call him, or get rid of him as soon as possible. If the opposite counsel perceive the bias to which I have referred, he may employ it to your ruin. In judicial inquiries, of all possible evils, the worst and the least to be resisted is an enemy in the disguise of a friend. You cannot impeach him; you cannot cross-examine him; you cannot disarm him; you cannot indirectly, even, assail him; and if you exercise the only privilege that is left to you, and call other witnesses for the purposes of explanation, you must bear in mind that, instead of carrying the war into the enemy's country, the struggle is still between sections of your own forces, and in the very heart, perhaps, of your own camp. Avoid this, by all means.

V. Never call a witness whom your adversary will be compelled to call. This will afford you the privilege of cross-examination,—take from your opponent the same privilege it thus gives to you,—and, in addition thereto, not only render everything unfavorable said by the witness doubly operative against the party calling him, but also deprive that party of the power of counteracting the effect of the testimony.

VI. Never ask a question without an object, nor without being able to connect that object with the case, if objected to as irrelevant.

VII. Be careful not to put your question in such a shape that, if opposed for informality, you cannot sustain it, or, at all events, produce strong reason in its support. Frequent failures in the discussions of points of evidence enfeeble your strength in the estimation of the jury, and greatly impair your hopes in the final result.

VIII. Never object to a question from your adversary without being able and disposed to enforce the objection. Nothing is so monstrous as to be constantly making and withdrawing objections; it either indicates a want of correct perception in making them, or a deficiency of real or of moral courage in not making them good.

IX. Speak to your witness clearly and distinctly, as if you were awake and engaged in a matter of interest, and make him also speak distinctly and to your question. How can it be supposed that the court and jury will be inclined to listen, when the only struggle seems to be whether the counsel or the witness shall first go to sleep?
