 horse should feel less pain from the action of the 

 curb-bit which is in condradiction to what is sta-

 tlie arc is in the same plane with that of the cheeks 

 of the curb-bit, (as curb-bits are usually made) 

 tlie lower cheeks should be made to come very 

 much back to form a right angle with the bars. 

 To allow this it would be necessary to have- the

 the cannon sliould make half a right angle with 

 the plane of the cheeks. Then if the lower cheeks
