These incidents illustrate the soundness of the well-known proposition, that mixture of truth with falsehood, augments to the highest degree the noxious power of the venomous ingredient. That man was no mean proficient in the art of deceiving, who first discovered the importance of the liar being parsimonious in mendacity. The mind has a stomach as well as an eye, and if the bolus be neat falsehood, it will be rejected like an over-dose of arsenic which does not kill.
Let the juryman ponder these things, and beware how he lets his mind lapse into a conclusion either for or against the prisoner. To perform the duties of his office, so that the days which he spends in the jury-box will bear retrospection, his eye, his ears, and his intellect, must be ever on the watch. A witness in the box, and the same man in common life, are different creatures. Coming to give evidence, "he doth suffer a law change." Sometimes he becomes more truthful, as he ought to do, if any change is necessary; but unhappily this is not always so, and least of all in the case of those whose testimony is often required.
I remember a person, whom I frequently heard to give evidence quite out of harmony with the facts; but I shall state neither his name nor his profession. A gentleman who knew perfectly well the unpalatable designation which his evidence deserved, told me of his death. I ventured to think it was a loss which might be borne, and touched upon his infirmity, to which my friend replied in perfect sincerity of heart, "Well! after all, I do not think he ever told a falsehood in his life--_out of the witness' box_!"
Viotti's division of violin-playing into two great classes--good playing and bad playing--is applicable to Bank-note making. We shall now cover a few pages with a faint outline of the various arts, stratagems, and contrivances employed in concocting bad Bank-notes. The picture cannot be drawn with very distinct or strong markings. The tableaux from which it is copied, are so intertwisted and complicated with clever, slippery, ingenious scoundrelism, that a finished chart of it would be worse than morally displeasing--it would be tedious.
All arts require time and experience for their development. When anything great is to be done, first attempts are nearly always failures. The first Bank-note forgery was no exception to this rule, and its story has a spice of romance in it. The affair has never been circumstantially told; but some research enables us to detail it:--
