So it is with portrait-painting, which is, after all, nothing but a right reading of the externals of character recognizably presented to the view of others.
Experience, after repeated trials, has proved to me that the only way of getting sitters who persist in assuming a set look to resume their habitual expression, is to lead them into talking about some subject in which they are greatly interested.

If I can only beguile them into speaking earnestly, no matter on what topic, I am sure of recovering their natural expression; sure of seeing all the little precious everyday peculiarities of the man or woman peep out, one after another, quite unawares.

The long, maundering stories about nothing, the wearisome recitals of petty grievances, the local anecdotes unrelieved by the faintest suspicion of anything like general interest, which I have been condemned to hear, as a consequence of thawing the ice off the features of formal sitters by the method just described, would fill hundreds of volumes, and promote the repose of thousands of readers.

On the other hand, if I have suffered under the tediousness of the many, I have not been without my compensating gains from the wisdom and experience of the few.

To some of my sitters I have been indebted for information which has enlarged my mind--to some for advice which has lightened my heart--to some for narratives of strange adventure which riveted my attention at the time, which have served to interest and amuse my fireside circle for many years past, and which are now, I would fain hope, destined to make kind friends for me among a wider audience than any that I have yet addressed.
Singularly enough, almost all the best stories that I have heard from my sitters have been told by accident.
