patience in correcting the faults, and substituting the correct mental orders for the one general order which starts the old train of vicious habitual movements. The mental habit must be first attacked and this mental habit usually lies below the level of consciousness; but it may be reached by introspection and analysis, and by the performance of the habitual acts by other than the habitual methods, that is, by physical acts performed consciously as an effect of the conscious conception and the conscious direction of the mind. Speaking generally, it will be found that the pupil is quite unable to analyse his own actions. Tell a young golfer that he has taken his eye off the ball or swayed his body, and he feels sure, in his heart, that you are mistaken. The imperfectly poised person has not a correct apprehension of what he is really doing. In this apparently simple matter of the carriage or poise of the body I find in quite nine-tenths of my cases a harmful rigidity[15] which is quite unconsciously assumed. When it is pointed out to them, and physically demonstrated, they almost invariably deny it indignantly. I ask a new pupil to put his shoulders back and his head forward, and he will consistently put both back or forward. I tell a new pupil he is shortening his spine, and in attempting to lengthen it he invariably shortens it still more. The action is one over which he has neither learnt nor practised any control whatever. He is simply deluded regarding his sensations and unable to direct his actions. I do not therefore in teaching him actually order him to lengthen his spine by performing any explicit action, but I cause him to rehearse the correct guiding orders, and after placing him in a position of mechanical advantage I am able by my manipulation to bring about, directly or indirectly as the case may be, the desired flexibility and extension. The process is of course repeated until the pupil gains a new kinæsthetic sense of the new and correct use of the parts, which become properly co-ordinated, and the correct habit is established. He will then no longer find it easy to cause his physical machinery to work as it did before the fault was thus effectively eradicated.
