In speaking of art we often contrast the useful or mechanical arts with the Fine Arts; by these terms we denote the difference between the arts which are used in making such things as are necessary and useful in civilized life, and the arts by which ornamental and beautiful things are made. The fine arts are Architecture, Sculpture, Painting, Poetry, and Music, and though we could live if none of these existed, yet life would be far from the pleasant experience that it is often made to be through the enjoyment of these arts. In speaking of Painting, just here I wish to include the more general idea of pictures of various sorts, and it seems to me that while picture-making belongs to the fine or beautiful arts, it is now made a very useful art in many ways. For example, when a school-book is illustrated, how much more easily we understand the subject we are studying through the help we get from pictures of objects or places that we have not seen, and yet wish to know about. Pictures of natural scenery bring all countries before our eyes in such a way that by looking at them, while reading books of travel, we may know a great deal more about lands we have never seen, and may never be able to visit. Who does not love pictures?
