HORSKSHOEING. • 593 



A hoof of tk€ hase-tfidc pmtition is always awry. The outer Avali 

 is- more slanting, longer, and thicker than the inner, tlie outer 

 (juartor more curved tiian the inner, and tlie outer half of the sole 

 vider than the inner. The weight falls largely into the inner half 

 of the hoof. In motion the hoof is moved in a circle. From its 

 position on the ground it breaks over the inner toe, is canied for- 

 wanl and inward close to the supporting leg, thence forward and 

 outward to the ground, which the hoof meets Hrst with the outer 

 toe. Horses that are toe-wide ("splay-footed" — toes turned out- 

 ward) show all these peculiarities of hoof-ft)rm and hoof-ilight to 

 a still moiv marked degree and are therefore nioi-e ])rone to "inter- 

 fere " when in motion. 



..-1 Iwof of tlie bnse-iuuv'ow position is awry, but not to so marked a 

 degree as the base-wide hoof. The inner wall is usually a little more 

 slanting than the outer, the inner half of the sole wider than the 

 outer, and the inner quarter more curved than the outer. The outer 

 quarter is often flattened and drawn in at the bottom. The weight 

 falls largely into the outer half of the hoof. In motion the hoof 

 breaks over the outer toe, is carried forward and outward at sonic 

 distance from the supporting leg, thence forward and inward to tho 

 ground, which it generally meets with the outer toe. The foot thus 

 moves in a circle, whose convexity is outward, a manner of flight 

 called " paddling.*' A base-narrow horse, whose toes point straight 

 ahead, frequently "interferes,"' while a toe-narrow (pigeon-tood ) 

 animal seldom does. 



^1 regxihtr hoof (fig. 56), viewed from one side, has a straight foot- 

 axis inclined to the horizon at an angle of 45^ to 50°. The weight 

 falls near the center of the foot and there is motlerate expansion of 

 the qu artel's. 



An (wute-anfjUd hoof (fig. 5«) has a straight foot-axis inclined at 

 an angle le.ss than 45° to the horizon. The weight falls more largely 

 in the back half of the hoof and there is greater length of hoof in 

 contact with tin- ground and gieater expansion of the heels than in 

 the regular hoof, 



T^jtright or stumpif hoof. — In the upright or stumj\v hoof (fig. tx-) 

 the foot-axis is straight and more than 55" steep. The hoof is rela- 

 tively short from toe to heel, the weight falls farther foiward, and 

 there is less expansion of the heels than in the regidai- hoof. 



M'idt' and n/in'oir hoofs. — Finally, there art' wide hoofs and nar- 

 row hoofs, dependent solely upon race and breeding. The wide hoof 

 is almost circular on the grotind surface, the sole but little concave, 

 the frog large, and the quality of the horn coarse. The narrow hoof 

 has a .strongly " cupped " sole, a small frog, nearly perpendicular 

 side walls, and fine-grained, tough horn.
