This book is an attempt to put into definite form the principles observed by the masters of the short story in the practice of their art. It is the result of a careful study of their work, of some indifferent attempts to imitate them, and of the critical examination of several thousands of short stories written by amateurs. It is designed to be of practical assistance to the novice in short story writing, from the moment the tale is dimly conceived until it is completed and ready for the editor's judgment.
