is sufficient ; more than one is not only unnecessary, but at 

 times even dangerous. A horse, when biting a hind leg, may 

 get the foot over one of the head collar shanks, (when two are 

 used^ and by this means the animal may be cast in the stall, 

 and death speedUy ensue unless assistance be at hand. I 

 remember two instances where valuable horses died in conse- 

 quence of being so caught. 



The Roller. — The EoUer is the part over and behind which 

 the shank passes, to make the horse secure in the stall. The 

 proper place to fix the roller is the central part of the manger, 

 near to its lower edge. It is usual to jBx an iron ring to this 

 part, but it neither looks nor acts so well as a roller. The form 

 of the EoUer should be as represented in the accompanying 



engraving.* Its length should 

 „— be about twelve or fourteen in- 



^ 



ches, and the diameter at its 



thickest parts four inches. Some 



horses have a practice of becom- 



,|il ing entangled with a fore Umb in 



i the head collar shank ; they seem 



to take a delight in the practice ; 



and many are the contrivances to prevent them. The most 



simple plan is to box the shank from the top edge of the manger 



down to the ground, leaving, of course, a smaO opening or door 



at the bottom, so that the clog or weight can be got at when 



desired. If the plan described should not succeed, it will be 



necessary to box the coUar shank against the side of the stall, 



as close to the front of the manger as the boxing can be fixed. 



Such boxing will require to rise from the floor to about fourteen 



or eighteen inches higher than the manger. The collar sh^nk 



* The Boiler is made thicker at each end, by which means the collar 

 shank will always work in the middle.
