 remember two instances where valuable horses died in conse- 

 quence of being so caught. 



Tlie Boiler. — The Eoller is the part over and heJiind 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 fix an iron ring to this 

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

 The form of the Eoller should be as represented in the accom- 

 panying engraving.* Some horses 



have a practice of becoming en-

 top edge of the manger down to 

 the ground, leaving, of course, a small 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 collar shank against the side of the stall, as close to 

 ithe 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 shank will 

 of course require to be of an additional length, and the clog 

 heavier in proportion. The adoption of this simple plan will 

 •efiectually prevent the practice, as the shank (if the clog be 

 sufficiently weighty, and the roller moves with freedom,) will be 



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

 jshank will always work in the middle.
