76 LESSONS IN HORSE JUDGING. 



where. By referring to Fig. 9, B, we see a 

 fore limb in extension, and see also that all the 

 powers (p) are applied in front of the limb. In 

 flexion we see Fig. 9, B, that all the powers are 

 applied at the hack of the hmb. Looking at 

 either of these figures we see that in every case 

 the power is placed very much nearer to the ful- 

 crum than the weight, the weight in each case 

 may be regarded as all the parts beneath its 

 respective fulcrum, so that it is evident that 

 speed is gained at very extensive sacrifice of 

 power. In all horses' Hmbs, no matter what 

 their length and strength, there is always this 

 relation of power to fulcrum, so that in all 

 horses' Umbs extent of movement or speed is 

 provided for more than power. 



68. — The shoulder blade has two distinct move- 

 ments. We have seen that it is dragged forward 

 by the levator humeri muscle. Its most exten- 

 sive movement is that of its lower end, which 

 gives to the whole blade a pendulum movement. 

 Both these movements are effected by this mus- 

 cle for the most part. 



59. — The arm bone has also two movements. 

 It is dragged backwards and forwards by the 

 levator humeri muscle. Its greatest movement, 

 however, is a pump-handle movement, having 

 its fulci*um or fixed point at the shoulder point. 



60. — It will be seen on reference to Fig. 9, (7, 1, 

 2, that we have two fore hmbs in flexion. The 

 figures are alike, but placed at different obliqui- 

 ties. On comparing the two it will be seen that 

 with the same amount of flexion the 'action'
