Of course I shall choose extreme cases to illustrate the contrast between them.

In the first, the figure is perhaps robust, but often otherwise,--inelegant, partly from careless attitudes, partly from ill-dressing,--the face is uncouth in feature, or at least common,--the mouth coarse and unformed,--the eye unsympathetic, even if bright,--the movements of the face are clumsy, like those of the limbs,--the voice is unmusical,--and the enunciation as if the words were coarse castings, instead of fine carvings.

The youth of the other aspect is commonly slender, his face is smooth, and apt to be pallid,--his features are regular and of a certain delicacy,--his eye is bright and quick,--his lips play over the thought he utters as a pianist's fingers dance over their music, and his whole air, though it may be timid, and even awkward, has nothing clownish.

If you are a teacher, you know what to expect from each of these young men.

With equal willingness, the first will be slow at learning; the second will take to his books as a pointer or a setter to his field-work.
The first youth is the common country-boy, whose race has been bred to bodily labor.
