the joker, the “smartie,” the echo or shadow, the quiet or reticent, the girl-struck, the self-conscious, the unconscious, and the forgetful.  Lastly, we should also consider the different types of the unfortunate boys, including the deficient, the delinquent, the criminal, the dependent, the neglected, the foreign born, the wage-earner, the poverty-stricken, boys of very wealthy parents, overambitious boys who have overambitious parents, and street boys who are either loafers or engaged in street trades, or are compelled to use the street as a playground.

THE CHOLERIC BOY

The choleric fellow who is always off at “half-cock,” running his head into danger whenever he can, and who is extremely hectic in his make-up, is always a problem.  He needs a strong hand.  Sometimes he will need even physical repression, but he always demands great care and patience.  The Teacher should deal with each class of boys largely by suggestion, but in the case of the choleric fellow he will often need to use orders and demonstrate that he himself is in the saddle.

THE SANGUINE BOY

The sanguine fellow is the normal boy who, having a good digestion, a good home and no cause for worry, sees things as they are and is apt to take them as they come.  He will be the easiest kind of a boy to get along with, and the only thing that the Teacher will have to do may be to provide for stimulation of his interest and ambition.

THE PHLEGMATIC TYPE

The phlegmatic chap requires patience more than anything else; generally slow of body, he is usually slow of speech and thought.  If the Teacher is not careful he will be apt to call him “dense,” and speak to him sharply and at times rather crossly.  He cannot do this if he expects to win the fellow.  Temperamentally, nature has made him what he is, and the Teacher will have to work harder, make things more concrete that he wants to teach, and hold his impatience in check.  Phlegmatic though he is, he will prove solid in everything he does, and he will be either a rock of strength or of weakness to the Teacher.  If he likes the Teacher nothing will shake his love, but if he has a dislike for him, then the Teacher is at the end of his endeavor as far as he is concerned.

THE HYBRID BOY IS A PROBLEM

The hybrid boy always furnishes a guessing contest—­impulsive today, he has to be repressed; phlegmatic tomorrow, he has to be stimulated; and he may be sanguine the next day.  There never was a pleasanter boy to work with, but like the chameleon you are never sure of his color.

    “Breath of balm and snow,
    June and March together,
    In an hour or so.”

Just because he is so changeable the Teacher should show him his best thought and work.  It is just such fellows who are inclined to be shiftless and who are generally crowded out in the fight for life.  Somewhere in the boy’s nature, if the Teacher is patient, he will find the rock bottom upon which to build manhood and citizenship.  Such achievement, however, comes only by great patience and hard work.
