nails OF the shoe are usually driven
about abrest Of the bbruise. This
serves to prevent the slight expan-
sion at that point by causing q rig
idity of the wall and encouraging
contracting pressure on the corn's
seat. The nails should be forward
OF this point and therefore entirely
In front Of the expanding portion Of
the hoOf.
The heels OF the shoe should be
shortened, the Aforesaid book not
| withstanding. to the extent that no
/ portion OF them extend beyond the
bearing Of the ground surface.
The shoe heels should also con-
form In obliquity to that Of the hoofs
heel. Neither should the ground
surface Of the foot be shortened or
trimmed perpendicularly SO greatly
that the frog will rest on the ground
when the horse Is at rest. My own
experiments show that the frog. ono
quarter OF an inch above the ground
surface will descend and touch the
ground when the weight OF the horse
in motion Is thrown upon the foot.
The greater tho speed Of the animal
the greater the frogs descent.
This is caused by the concaved sole
being forced down by the coffin bono
and the downward action expands
the hoof. Should the frog be al
ready upon the ground when the
horse Ia resting there js no room for
its descent when In motion. there
fore no play up or down Of the sole
and no lateral expansion. Such mo-
tion or exercise is essential to the
health Of the foot.
II is true the heels OF the fore feet
are first to strike the ground when
the horse Is jogging or at speed. The
faster the motion the more pro-
nounced is the heel blow and the
greater the conclusion. As these
feet bear the corns and are sore the
concussion produces pain. The high
er the heels in proportion to the an
terror foot the greater the concus-
sion. Also the further the heels OF
tn shoe project the greater the con-
cussion. Such being the case any |
alienation of the blows force ia OBJ |
vious. L. e., lower the heel Of the foot |
and shorten that Of the shoee, for |
its reduction.
Heel corks are injurious because
they add to the concussion. The |
heel OF the shoe should be even thin |
ner than other portions OF the shoe.
Now bear in mind there is a happy
medicine governing the obliguity !
or angle of the foot II the heels |
are too high the weight OF the ami |
NAL is thrown forward and princi |
pally upon the bones OF the foot. pro- |
ducing undue conclusion. II too low |
this weight is thrown back upon the
navicular bone and the tendons sup
porting it. With the right obliguity |
this weight is approximately one
third ON the coffin bone and two |
thirds on the navicular. This angle |
varies in individuals. but the average
for the front feet ID so to So degrees

that excessive thinning of the ground |
surface leads to contraction. II shod.
for the reason that the shorter the |
hoof Is smaller. The ground cir |

Much Is written regarding the bars |
being preventative of contraction |
and would-be authorities discounten-
ance the trimming OF them more |
than to level with the hoof wall. |
These do not prevent contraction and |
are not so purposed. They stiffen |
the arch of the ole however. and " |
left as directed invite contraction by |
not allowing the needful downward |
movement when under weight
With the foot properly prepared
and shod upon the lines laid down
here the bruise to form the corn |
cannot occur, and when 1t has pre-
viously occurred the cause will be
removed and the injury cured
