them with your mind’s eye, until you can visualize the features of very old friends; then do the same with acquaintances, and so on, until you are able to visualize the features of every one you “know.” Then start on to add to your list by recalling in the imagination, the features of strangers whom you meet. By a little practice of this kind you will develop a great interest in faces and your memory of them, and the power to recall them will increase rapidly. The secret is to study faces—to be interested in them. In this way you add zest to the task, and make a pleasure of a drudgery. The study of photographs is also a great aid in this work—but study them in detail, not as a whole. If you can arouse sufficient interest in features and faces, you will have no trouble in remembering and recalling them. The two things go together.
