CONSTRUCTION AND FITTING OF STALLS. 239 



required to enable it to perform its special work, the horse 

 will be in no way incommoded by the log being off the 

 ground, when his head is on the floor. 



Some horses have the annoying and hurtful vice of 

 endeavouring to get a fore-leg over a line by which they are 

 tied up. Such old offenders can generally be recognised by 

 the presence of a wound, recent or healed up, at the back of a 

 fore-leg just below the knee. I know no cure for this vice, and 

 the only safe preventive measure I can suggest, is the 

 substitution of a loose box for a stall. Cases of horses getting 

 a fore-leg over a tying line by accident are almost always 

 caused by the line being too long in comparison to the height 

 of the pulley, or by the line failing to run freely through the 

 pulley (or ring). 



The plan of tying up a horse with two lines, the respective 

 pulleys of which should not be less than 4 ft. apart, is far 

 preferable to that of tying him up by a single attachment ; for 

 by the former, the animal is much less liable to the serious 

 danger of getting a leg over a line than with the latter. Be- 

 sides, I am strongly of opinion that if a horse gets cast, he 

 will be much more likely to regain his feet unaided, if tied by 

 two lines, than if tied by only one ; for with two lines, the line 

 of the side opposite to that on which he is cast, will be more 

 tense than a single line would be, and will on that account be 

 of more assistance to him when he tries to turn over on his 

 side. 



When a horse is tied up with two lines, each of them will 

 obviously have to be longer than when a single line is used. 

 Here the proportion between the length of each line, and the 

 height of Jts pulley off the ground, cannot be fixed, as it will 

 vary according to the distance between the two pulleys. 



A rack-chain (Fig. 26) is used in stall or box to confine a 

 horse within narrow limits, in order, for instance, to keep him 

 quiet when being groomed, and to prevent him from feeding or
