20 LESSONS IN HORSE JUDGING. 



in man called the ankle. We find, still referring 

 to Fig. 3, that we have in the living lever a power 

 in front and another behind the leg bone. 



Now to illustrate our three orders of levers, we 

 find we have only to study the hock- joint in the 

 trot. The first order is seen in the hock in the 

 trot after the foot has been hf ted from the ground. 

 To bring it quickly to the ground we find the ful- 

 crum at the true hock- joint, the power attached 

 behind to the point of the hock, and the iveight 

 to be moved, and all the parts below the hock, 

 including, of course, the foot. 



To illustrate our lever of the second order, take 

 the hock in the trot when the foot is placed o?ithe 

 ground. We now find the fulcrum and weight 

 have changed places, but the power is still as in 

 the first order, behind the hock. The foot being 

 planted on the ground is now the seat of i\iQ ful- 

 crum, or fixed point, and the iveight is the whole 

 of the body which is thrown on to the true hock- 

 joint, and is the obstacle to be overcome, and is 

 being hfted and pushed forward. 



Lastly, our lever of the third order is seen in 

 the hock during the trot, when the hind leg is 

 left behind after pushing the body forward, and 

 has to be lifted and pulled forward before it can 

 again be brought forward under the body (this is 

 the same action, and better seen, when the him 

 foot is being lifted to knock of a fly that is irri- 

 tating the belly), the front power is now acting, 

 and the weight and fulcrum are the same as in 

 the example of the third order, or, in other words, 

 the power is in the middle.
