THE HORSE. 35 



called into such violent exertion, or so frequently as the 

 three kinds above-mentioned, yet from being set a great 

 deal upon his haunches, and having to halt suddenly, 

 and being heavily weighted, requires much strength 

 here. This is one of the principal reasons why cast 

 troop horses are usually found such good workers. 



Ladies' horses, perhaps, have their hocks most tried 

 in proportion to the weight they carry, from their con- 

 tinually cantering. This pace is most calculated to try 

 these joints, from the long exertion required in the one 

 pace. If proper horses for ladies to ride, they are "well 

 upon their haunches/' and stop as well as the charger, 

 with their hind legs well under them. 



In fact, no horse can be either easy, safe, or satis- 

 factory to ride, that does not take a large proportion 

 of his burden on his hind legs. 



The hackney has some relief by change from one pace 

 to the other. But to be a superior hackney, he must 

 take the weight on his hind legs ; this enables him to 

 go in a corky, light, and springy manner, no shaking. 

 You will hear this perfection thus described : " He goes 

 as light as a cork/' " would not break an egg/' Horses 

 thus trained cannot shake you ; there is no " bone- 

 setting " (a term used to describe the reverse), neither 

 can he fall or stumble. 



The harness horse has neither to canter nor leap, 

 neither has he weight upon his back. Here you have 

 to consider the speed required, and the weight he has
