_expression_ of a person's eye, you will be very apt to recognize it thereafter. Therefore concentrate on eyes in studying faces. A good plan in developing this faculty is to visualize the faces of persons you have met during the day, in the evening. Try to develop the faculty of visualizing the features of those whom you know--this will start you off right. Draw them in your mind--see 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. CHAPTER XIII. HOW TO REMEMBER PLACES. There is a great difference in the various degrees of development of "the sense of locality" in different persons. But these differences may be traced directly to the degree of memory of that particular phase or faculty of the mind, which in turn depends upon the degree of attention, interest, and use which has been bestowed upon the faculty in question. The authorities on phrenology define the faculty of "locality" as follows: "Cognizance of place; recollection of the looks of places, roads, scenery, and the location of objects; where on a page ideas are to be found, and position generally; the geographical faculty; the desire to see places, and have the ability to find them." Persons in whom this faculty is developed to the highest degree seem to have an almost intuitive idea of direction, place and position. They never get lost or "mixed up" regarding direction or place. They remember the places they visit and their relation in space to each other. Their minds are like maps upon which are engraved the various roads, streets and objects of sight in every direction. When these people think of China, Labrador, Terra del Fuego, Norway, Cape of Good Hope, Thibet, or any other place, they seem to think of it in "_this_ direction or _that_ direction" rather than as a vague place situated in a vague direction. Their minds think "north, south, east or west" as the case may be when they consider a given place. Shading down by degrees we find people at the other pole of the faculty who seem to find it impossible to remember any direction, or locality or relation in space. Such people are constantly losing themselves in their own towns, and fear to trust themselves in a strange place.
