Illustration of Twain from
THE SKETCH, Nov. 27, 1895

That impressive silence, that eloquent silence, that geometrically progressive silence which often achieves a desired effect where no combination of words howsoever felicitous could accomplish it.... For one audience, the pause will be short; for another a little longer; for another a shade longer still; the performer must vary the length of the pause to suit the shades of difference between audiences. ... I used to play with the pause as other children play with a toy.
