Assuming that the material with which you propose to assail the credibility of a witness fully justifies the attack, the question then arises, How to use this material to the best advantage? The sympathies of juries are keen toward those obliged to confess their crimes on the witness-stand. The same matters may be handled to the advantage or positive disadvantage of the cross-examiner. If you hold in your possession the evidence of the witness's conviction, for example, but allow him to understand that you know his history, he will surely get the better of you. Conceal it from him, and he will likely try to conceal it from you, or lie about it if necessary. "I don't suppose you have ever been in trouble, have you?" will bring a quick reply, "What trouble?"—"Oh, I can't refer to any particular trouble. I mean generally, have you ever been in jail?" The witness will believe you know nothing about him and deny it, or if he has been many times convicted, will admit some small offence and attempt to conceal everything but what he suspects you know already about him. This very attempt to deceive, if exposed, will destroy him with the jury far more effectually than the knowledge of the offences he has committed. On the other hand, suppose you taunt him with his crime in the first instance; ten to one he will admit his wrong-doing in such a way as to arouse toward himself the sympathy of the jury and their resentment toward the lawyer who was unchristian enough to uncover to public view offences long since forgotten.
Chief Baron Pollock once presided at a case where a witness was asked about a conviction years gone by, though his (the witness's) honesty was not doubted. The baron burst into tears at the answer of the witness.
In the Bellevue Hospital case (the details of which are fully described in a subsequent chapter), and during the cross-examination of the witness Chambers, who was confined in the Pavilion for the Insane at the time, the writer was imprudent enough to ask the witness to explain to the jury how he came to be confined on Ward's Island, only to receive the pathetic reply: "I was sent there because I was insane. You see my wife was very ill with locomotor ataxia. She had been ill a year; I was her only nurse. I tended her day and night. We loved each other dearly. I was greatly worried over her long illness and frightful suffering. The result was, I worried too deeply; she had been very good to me. I overstrained myself, my mind gave way; but I am better now, thank you."

GOLDEN RULES FOR THE EXAMINATION OF WITNESSES
David Paul Brown, a member of the Philadelphia Bar, has condensed his experiences into eighteen paragraphs which he has entitled, "Golden Rules for the Examination of Witnesses."
Although I am of the opinion that it is impossible to embody in any set of rules the art of examination of witnesses, yet the Golden Rules of Brown contain so many useful and valuable suggestions concerning the art, that it is well to reprint them here for the benefit of the student.
