TRAVEtiSlN.i IN TtiE PASSAGE. 83 



sary, the horse to the line, is also used 

 to prevent the croup passing over too 

 far, but, of course, does not serve to 

 heighten the action of the two legs it 

 would act upon in the passage in direct 

 lines ; it rather checks them, though it 

 is not intended that the inside spur 

 should take any part in producing the 

 action of the passage in the traverse. 



At each step the weight of the hors.^ 

 is supported by a fore-leg and the hind- 

 leg diagonally opposed, while the other 

 two legs are carried beyond them in 

 the direction of the movement. The 

 manner in which the weight is thus 

 borne permits the horse to keep his 

 balance as he goes to the right or to 

 the left, and avoids the danger of 



tripping.
