LESSONS IN HORSE JUDGING. 21 



Summarizing what has been said of the three 

 orders of lever as exemphfied by the hock- joint 

 in trotting, we have f omid first, that the weight 

 is all parts below the hock when the foot is ojf 

 the ground, and all parts above the hock when 

 the foot is on the ground. Second, when the foot 

 is off the ground and swinging backwards the 

 lever is of the first order, but when swinging for- 

 wards it is of the third order, whilst it is of the 

 second order when on the ground.
