In discussing the fitting- of the bridle, the instructor will also teach 

 the following : 



The snaffle bit acts on the corners of the horse's month and when 

 the rein becomes active, tends to elevate the horse's head. The curb bit 

 acts on the bars and when active lowers the horse's head. Because of 

 the fact that the curb acts on the "bars" and that leverage is obtained, 

 this bit is much more severe than the snaffle. 



In teaching the theor}^ of the application of aids, impress on the 

 recruit the eiTect which the application lias on the horse. In every case 

 show the effect of contradictory aids. 



In general the voice has the following effects : 



(1) To soothe or quiet. 



(2) To encourage. 



(3) To admonish. 



The weight has the following effects • 



(1) To act as a brake, (the halt, for example). 



(2) To change the center of gravity of the horse. 

 The rein aids have the following effects : 



(1) To assist in changing direction. 



(2) To diminish the gait. 



(3) To change the center of gravity of the horse. 

 The leg aids may be classified as follows : 



(1) Active: ('Eor example, both legs are active when applying the 

 forward leg aids.) 



(2) Passive: (For example, both legs are passixe when they are not 

 applying an aid. as when the rider is moving at the gait he desires 

 while on a straight line.) 



(3) Guarding: (For example, in circling left, the right leg is carried 

 back slightly in order to be in a position to prevent the haunches swing- 

 ing to the outside of the circle. If the haunches remain on the circle 

 the right leg remains passive, but if haunches tend to swing outside, 

 the leg becomes active.) 



The instructor will obtain excellent results in this subject, if he will 

 first read a paragraph from the book and then in his own words, explain 

 and discuss it. His discussion where possible should include a hypo- 

 thetical case to illustrate and bring out the point he desires to impress.
