PRACTICAL HORSESHOEING.

Fig. 23. showing under surface of 

 a perfect front hoof troperly pre- 

 pared for the shoe, with guide lines 

 for leveling and balancing the foot. 



A, Center of frog cleft in line 

 with the insertions of front and 

 back tendons, and parallel to their 

 straight line of movement. B, B, 

 Line through longitudinal center 

 of foot, dividing it into exact 

 halves and indicating middle of 

 heels and front toe. C, C, Line 

 transversely across center of foot, 

 midway through inside and out- 

 side quarters. The point of inter- 

 section of these lines indicates the 

 normal center of gravity. D, D, 

 D, D, Intersecting lines marking 

 the width of inside and outside 

 toes and heels. E, E, Branches 

 or forks of the frog on either side 

 of the median cleft. F, F, Bars 

 on either side of the frog. G, G, 

 Commissures or grooves between 

 the bars and frog. H, H, H, H, 

 Line marking height of heels from 

 coronet to base. I, I, Concave 

 surface of sole. J, J, J, J, Wall- 

 bearing surface leveled and pre- 

 pared for the shoe. 



These lines indicate the main points where the wall of the 

 hoof is to be measared from the coronet to the lower rim or 

 base, in order to obtain equal and exact levels around the entire 

 circuit. The height of any two opposite points on either side 

 of line B, B, must correspond, that is, the sides of toe and heels 

 and quarters must be alike to insure proper levels, and the 

 width from the converging center, near point of frog, to any 

 radiating point on opposite sides must be equal to secure a per- 

 fectly-balanced foot.
