I cannot claim that this book will be more than an interim report. Certainly, the matter of it may be new to many readers; but this has been accumulated over five years more by head and hand than by eye and ear. Certainly, the subject is important to all who have human culture and human individuality at heart. But communications and opportunities of visiting the Soviet Union in recent years have been infrequent. Certainly, also, the very speed of development and rapid changes in the Soviet Theatre may make it seem arbitrary to fix any point at which a survey of its growth can usefully be made.
