Dr. Veron, who has left upon record a sort of secret history of his management of the Paris Opera House, has revealed many curious particulars concerning _les claqueurs_, adding a serious defence of the system of artificial applause. The artistic nature, the doctor maintains, submitting its merits to the judgment of the general public, has great need of the exhilaration afforded by evidence of hearty approval and sympathy; the singer and the dancer are thus inspired with the courage absolutely necessary to the accomplishment of their professional feats; and it is the doctor's experience that whenever a song or a dance has been redemanded by the audience, the dance has been better danced, and the song better sung, the second time of performance than the first. Hence there is nothing harmful, but rather something beneficial, in the proceedings of _les claqueurs_. Every work produced at the theatre cannot be of the first class, and legitimately rouse the enthusiasm of the public; every dramatic or lyrical artist cannot invariably, by sheer force of talent, overcome the coldness, the languor, or the indifference of an audience; yet the general effect of the representation would suffer much if all applause, including that of a premeditated and, indeed, purchased kind, were entirely withheld; the timid would remain timid, talent would remain unrecognised, and, therefore, almost unrevealed, if no cheering were heard to reassure, to encourage, to kindle, and excite. The suggestion that the public would supply genuine applause if only the _claqueurs_ were less liberal with the spurious article, Dr. Veron rather evades than discusses.
