Bits 81 



The mouthpiece Is frequently bent in 

 the middle, forming what is called the 

 ' Port,' so as to give room for the tongue 

 to play. This form of bit will be seen 

 on reference to figures 7, 8, 9 (Wey- 

 mouth bits). Some other patterns of 

 driving bits are shown in figures 10, 11 

 and 12. 



When fitting a bit the groom should 

 take particular care to see that the mouth- 

 piece is ot the proper width, and if a curb 

 be used, the latter should lie quite flat on 

 the chin groove, otherwise no matter how- 

 ever perfect the rest of the bit be, it will 

 not act properly if the curb is not carefully 

 adjusted. If the last named be too tight 

 it causes the animal pain, probably in 

 course of time galling the part when the 

 reins are pulled. About half an inch 

 should be left between the curb chain 

 and the 'chin Qfroove.'
