I have dwelt on the external condition of the American audiences in order to explain the condition antecedent to the actor’s appearance. The differences between various audiences are so minute that some such insight seems necessary to enable one to recognise and understand them. An actor in the ordinary course of his work can only partially at best realise such differences as there may be, much less attempt to state them explicitly. His first experience before a strange audience is the discovery whether or not he is _en rapport_ with them. This, however, he can most surely feel, though he cannot always give a reason for the feeling. As there is, in the occurrences of daily life, a conveyance other than by words of meaning, of sentiment, or of understanding between different individuals, so there is a carriage of mutual understanding or reciprocity of sentiment between the stage and the auditorium. The emotion which an actor may feel, or which his art may empower him successfully to simulate, can be conveyed over the floats in some way which neither actor nor audience may be able to explain; and the reciprocation of such emotion can be as surely manifested by the audience by more subtle and unconscious ways than overt applause or otherwise. It must be remembered that the opportunities which I have had of observing audiences have been almost entirely from my own stage. Little facility of wider observation is afforded to a man who plays seven performances each week and fills up most of the blank mornings with rehearsal or travel. I only put forward what I feel or believe. Such belief is based on the opportunities I have had of observation or of following out the experience of others.
