PREFACE.

It is due to the late General Sir Frederick Fitzwygram to
give credit;to:his book, ‘Horses and Stables,” for very much
that is contained in this work, and the author wishes to thank
his widow and her son, the present Sir Frederick Fitzwygram,
for their kind permission to quote ‘from it.

. “Horses and Stables’’ has been the hand-book and guide
of the American cavalry officer since the issuance of its first
edition, and it is deeply regreted by us all that the fifth edition
is to be the last to be revised by its talented author.

Saneen

and Barrier, and Captain Seton, and the admirable work of the
Department of Agriculture on the ‘Diseases of the Horse,”
which have been the author’s guide during his service as a cav-
alry officer, have also been freely consulted. Whatever ideas
he has developed in his experience flow from suggestions re-
ceived from these and similar works. Nothing new is claimed or
attempted. The effort has been made to write a comprehen-
sive book that will cover, in outline only, all general subjects
that a horseman should know.

All of the anatomical illustrations are taken from ‘ Dis-
eases of the Horse,” a public document issued by the Bureau
of Animal Industry, Department of Agriculture. The pho-
tographs for the rest of the illustrations, except as noted, were
taken by Mr. W. H. Stockbridge, under the author’s supervision,
from horses and polo ponies at the Military Academy, and rep-
resent ordinary conditions only. No effort is made to discuss
the so-called “horse of luxury,” which is, after all, only an ex-
ceptionally good specimen of the type that ought to be adhered
to in purchasing a horse for any special purpose.

Special thanks is due the editor of ‘‘The Rider and Driver,”
Mr. Samuel Walter Taylor, for his kindness in loaning photo-
graphs, and for the cover design.

CELA ei 4:

A GENERAL DISCUSSION. |

It is useless to attempt the description in a few words of the
origin and development of the modern horse;* we know that as
far back as authentic history reaches, horses have been used by
men for the manifold purposes of peace and war, toil and recrea-
tion. For many centuries past two general types of horses have
been preserved. One, which may be called the thoroughbred
type,is a light, active, speedy animal, possessing great endurance.
It finds its best uses for saddle and racing purposes. The other
type is more powerful, but not so active, nor as fast. This
type may be called, in general terms, the Flanders type. It is
used for draft purposes. By crossing these two types the many
special breeds and families of horses now in use arise.

A thoroughbred animal is, in the broadest meaning of the
term, one of pure blood, descended for many generations from
animals of the same sort. Thus, one may speak with perfect
propriety of a thoroughbred fox-terrier dog, or of a thorough-
bred Jersey cow, or of a thoroughbred Cotswold sheep. A thor-
oughbred horse, however, is a race-horse—not necessarily used
for racing purposes—descended through a line of racers, from
Arab stock. Any other sort of a horse that is of pure strain, de-
scended from known ancestors of the same strain, should not be
called thoroughbred, but pure-bred.

*Those who are interested in this subject will find “The Origin
and Influence of the Thoroughbred Horse,’ by William Ridgeway

(Cambridge, University Press), interesting and exhaustive.

2 ELEMENTS OF HIPPOLOGY.

A stud-book is a book that is kept for the purpose of re-

cording the pedigree and performances of thoroughbred animals. —

The stud-book for the American thoroughbred horse is kept by
the editor of the American Stud-Book, in New York City. . To
entitle a horse to be registered as a thoroughbred in this stud-
book, his ancestors, for at least six generations of sires and five
of dams, must have been so registered.

If, in examining the pedigree of a thoroughbred horse, an
ancestor not of pure Arabian blood is found, the horse is said to
have cold blood. |

A well-bred horse is one descended from a line of selected
sires and dams, chosen for the qualities they are known to im-.

part to their offspring, and whose rearing has been carefully
attended to.

The horse shown in Figure 1* is an example of what cen-
turies of intelligent breeding and the most scientific care can
accomplish.

An ill-bred or under-bred horse is one carelessly bred,
whose sires and dams have not been well chosen, and who, for
generations, have been neglected in their rearing.

Figure 2 shows an under-bred polo pony of poor quality.
This is a coarse animal, with abundant mane and tail. While
it is a perfectly sound, serviceable animal for slow, light work,
its sluggish nature, the result of careless breeding and rearing,
unfits it for anything that demands courage or stamina or spirit.

The varied uses to which horses are put has led breeders to
develop special strains of horses that will best accomplish the
special work demanded of them.

*This colt was bred by Mr. I. Simons Harrison at his stud-farm
in East Yorkshire, England, and it is due to his courtesy that the
photograph is introduced here.

Mr. Harrison says of him: “This colt is very handsome and

racing-like and on good lines. I hope he may, with luck, make a name
for himself on the turf.”’

For heavy draft purposes, the French Percheron and Eng-
lish Clydesdale are the most distinctive types. The former are
usually of gray color and the latter bay or brown. These are the
familiar heavy dray-horses; they weigh from 1,200 to 2,000
pounds, and are the most popular heavy work-horses in the
United States.

The English Shire horse is very similar to the Clydesdale,
and the French draft and Norman horses to the Percheron.
The Belgian and Flemish draft-horses are more ponderous
than either of the above breeds, and for that reason, probably,
have not caught the American horse-users’ fancy.

The coach-horses are bred for moderate speed, while
drawing fairly heavy loads. They are over sixteen hands high,
and weigh from 1,100 to 1,300 pounds. The best-known breeds
are the English coach, the French coach, and the Cleveland
bay. The last named is a breed developed in the United States.
These horses are not pure-bred, but are carefully bred from
selected individuals.

The hackney is a breed of driving-horses of English origin
very popular in the United States. They are stocky, strong,
active horses, full of courage and good temper, smaller than the
coach-horses, and much less rangy in build. Fashion demands of
them an exaggerated knee action when in motion and a peculiar
stretched-out pose when at rest.

The hunter is a saddle-horse of good size, with a strong
thoroughbred cross, good at jumping, and with excellent wind.
There is no particular breed of hunters. They are simply se-
lected individuals that have proven to be useful in cross-country
galloping. It is performance that makes a hunter.

The polo pony is another type of saddle-horse that depends
absolutely on his individual performances to make him of any
value in his class. Excellent polo ponies are bred from small
mares of the mustang type by Arabian or Spanish barb sires.

ELEMENTS OF HIPPOLOGY. 7

_ In the United States there have been developed three strains
of horses that are worthy of special notice on account of the in-
fluence each has had on the quality of the horses of the nation.
These strains are the American standard trotter, the Amer-
ican or Kentucky saddle-horse, and the Morgan horse.

The trotter is the result of an effort to produce the best an-
imal for racing under harness. The first horse to trot a mile in
harness in less than three minutes was Yankee, who performed
that feat at Harlem, N. Y., in 1806. It took a hundred years of
the most careful breeding to pass the two-minute mark, and
breeders are still trying to reduce the present record of 1:583,
made by Lou Dillon in 1903. |

The influence of remarkable individuals is singularly shown
in the breeding of American trotters of record. In 1884 there
were in the neighborhood of 6,000 horses in the United States
that had trotted in races that were of enough moment to be re-
corded. ‘‘Of these, a little over 1,700 are Hambletonians; there
are 657 other Messengers, making a total of 2,369 that trace in
male line to Messenger. There are 762 Black Hawks, and 453
other Morgans, or a total of 1,215 that trace in male line to Justin
Morgan. There are about 700 that trace in male line to Canadian
Sires, and the same number of Bashaws, with something over 300
which trace to thoroughbred sires other than those mentioned,
and about 1,000 whose tracing is not certain.’’*

In other words, in 1884, seven of every twelve trotting
horses of record traced back directly to Messenger or Justin
Morgan, and the same proportion is probably still true. The
greatest of Messenger’s descendants was Rysdyk’s Hamble-
tonian. He was not a thoroughbred.

The standard American trotter is a horse that has been
bred for racing under harness. It is of comparatively recent
date that any care has been taken in registering these horses.

FIGURE 7.—LorRD CLINTON, STANDARD MorGAN TROTTER.

Any horse that was speedy, or whose sire or dam was a fast
trotter, or pacer even, was admitted to registry in the stud-book
of the National Trotting Horse Breeders’ Association. This has
resulted in the greatest confusion in tracing pedigrees, and for
several years has not been permitted.

The term ‘‘standard-bred”’ is now applied to trotting horses
only that are bred to a certain standard of speed. The term does
not refer to the blood of the horse, but to the excellence of the
trotting performances of his sire and dam. The rules of the

ELEMENTS OF HAIPPOLOGY. 9

American Trotting Register Association, in whose records the
pedigrees of standard-bred horses are kept, set the following as
the trotting standard:

“When an animal meets these requirements and is duly regis-
tered, it shall be accepted as a standard-bred trotter:

“‘1. The progeny of a registered standard trotting horse and a
registered standard trotting mare.

“2. <A stallion sired by a registered standard trotting horse,
provided his dam and grandam were sired by registered standard trot-
ting horses, and he himself has a trotting record of 2:30 and is the sire
of three trotters with records of 2:30, from different mares.

“3. A mare whose sire is a registered standard trotting horse,
and whose dam and grandam were sired by registered standard trot-
ting horses, provided she herself has a trotting record of 2:30, or is the
dam of one trotter with a record of 2:30.

“4. A mare sired by a registered standard trotting horse, pro-
vided she is the dam of two trotters with records of 2:30.

“5. A mare sired by a registered standard trotting horse, pro-
vided her first, second, and third dams are each sired by a registered
standard trotting horse.”

The effect of this search for eed for racing purposes under
harness has been to give to the United States a fine breed of
light harness-horses. The standard trotter is not a saddle-horse;
he is too rangy to be a strong weight-carrier, and too long in his
stride to be a comfortable mount.

AMERICAN SADDLE-HORSE REGISTER.*

RULES FOR ENTRY.
In Effect August, 1904.

Rute 1. A stallion whose sire and dam are both registered in
Saddle Horse Register is eligible.

Rute 2. A mare whose sire or dam is registered and who
traces on other side to registered or foundation saddle stock is eligible.

RuLE 3. A gelding tracing on either side to registered or foun-
dation saddle stock is eligible.

Certificate of Owner or Manager of sire that mare was bred must
accompany all applications for foals of 1907 and after.

*This is the form used to register American saddle-horses and contains the
rules governing their entry. Fora thoroughbred registry, the sixth dam must be
registered to entitle the colt. to be called a ‘‘ thoroughbred.’’

ELEMENTS OF HIPPOLOGY. ts

For a number of centuries in England, whence the larger
proportion of our imported saddle-horses have come, saddle-
horses have been trained to three gaits only—the walk, trot, and
gallop. In the early years of the history of Kentucky, although
the country was prosperous and its people rich, the roads were
poor. The business of the State was done on horseback, and the
demand arose for a comfortable saddle-horse. To meet this de-
mand a breed of horses, now known as the American saddle-
horse, was developed. The Canadian pacer, a horse descended
from.French and English stock, was crossed with the thorough-
bred, and, by careful breeding, the present splendid breed of
saddle-horses has resulted.

They are medium-sized, well-built animals, of good color;
kind, docile, and willing. They jump well and gallop easily and
make ideal mounts for cavalry, but their chief distinction is the
possession of a number of artificial gaits that add greatly to the
comfort of their riders.

These horses can be used as light driving-horses without
injury to their gaits.*

The term ‘“‘breed,” as used by the farmer, signifies a group
or class of animals having a number of distinctive qualities and
characteristics in common, and the power to transmit those
distinctive traits with a good degree of certainty.

‘“‘A breed is usually started by selecting two or more unusu-
_ ally good animals from a group that has been produced in a lo-
cality by reason of better food, environment, and intelligent se-
lection, and which is usually superior to the animals of the same
species in other localities. These few having been selected, in-
breeding is practiced to a greater or less extent for the purpose
of perpetuating and intensifying one or more desired character-
istics. At first the work is usually carried on by one, or at most
a few, of the most intelligent breeders, who, by improving condi-
tions, have first improved the quality of their own stock.

*The description of these gaits will be found in Chapter XIX.

14 ELEMENTS OF HIPPOLOGY. -

“Tt will be readily seen that when the attempt is made to
launch a breed and establish a record of genealogy, or pedigree,
for the various animals selected for such record, the first pedi-
grees must be based on unpublished records. Not infrequently
some of the foundation stock is recorded simply by name, and —
nothing is said of ancestors, because nothing is known of them.”’*

From the above definition, the term “‘ breed’’ can hardly be
applied to the trotter, because the search has been more for
speedy individuals than for a class of horses possessing special
qualities. Until recently, pedigrees have been very loosely kept.
The Kentucky saddle-horse, although his breeding has been con-
temporary with that of the trotter, forms now a distinct breed,
whose individuals possess the power of transmitting their dis-
tinctive traits with reasonable certainty.

The Morgan family of horses is, in this sense, not a breed.
It includes the descendants of Justin Morgan, a horse foaled in
1789, three-quarters thoroughbred, and of such remarkable vir-
ility that his descendants to this day still bear unmistakably
many of the qualities that made their great progenitor famous.

The rules of admission to the Morgan Horse and Register
are these:

“1. Any meritorious stallion, mare, or gelding that traces in
direct line to Justin Morgan and has at least one-sixty-fourth of his
blood; provided the sire and dam were bred in approved speed or
roadster lines.

“2. Any meritorious stallion, mare, or gelding having one-
thirty-second or more of the blood of Justin Morgan; provided the
sire and dam were bred in approved speed or roadster lines.

“3. ‘The produce of a sire and dam both registered in the
Mergan Registry.”’

As a business-horse—a horse of all work—the Morgan horse
stands preeminent. No other stallion in the history of Western
horses possessed the power cf perpetuating good qualities to the
the extent possessed by Justin Morgan. The distinguishing

characteristics of his family are: beauty and symmetry of
conformation, hardiness, longevity, docility, willingness, and —
endurance. |

The light harness-horse and the lighter sort of work-horses
in the United States are, in the main, mongrels. They are so
badly bred, so crossed with conflicting strains, that little can be
predicted of the quality of the average foal, based on the qualities
of its sire and dam.*

The Arab horse is the aristocrat of the horse world. These
wonderful animals have been kept of pure blood for ‘‘a known
period of 3,500 years’’f in the deserts of Arabia. They have
furnished the uplifting, ennobling quality which has been intro-
duced in the blood of commoner horses from a period dating
back from 1600 to 2000 B. C.

Their influence is met with in the mustang of the Western
plains and in the small Philippine pony, both degenerate Arabs,
descending through the Spanish barb. Both are wiry, plucky
little animals, showing little of the graceful conformation of
their great ancestors, but much of their courage and endurance.

GENERAL DEFINITIONS.

The perfect male of the horse is called a stallion or an entire.
When altered (castrated), he becomes a gelding. The female
is a mare.

The young is called, for either sex, a foal. Specifically, the
male foal is a colt; the female a filly.

A colt, or filly, becomes of age when the corner incisor teeth
grow up level with the other incisors of the lower jaw,—about

*This condition has been realized by the better farmers of the
country for some years, and, due to this fact and to the efforts of the

Bureau of Animal Industry of the Department of Agriculture, the
quality of the cheaper grades of horses is being rapidly improved.

& Company, New York).

ELEMENTS OF HIPPOLOGY. id

five. He is aged, under the racing rules, at seven, when he is
considered thoroughly mature.

The period of gestation is eleven months. The age of the
horse is usually reckoned from the first of January preceding
birth. For purposes of record, a thoroughbred foal becomes a
yearling on January first after his birth.

To aid in the recognition of horses, they are described by
giving their color, sex, age, height, color of mane and tail, points,
and by detailing their marked peculiarities. In this description
certain technical terms are used:

A snip is a patch of white (skin and hairs) on the nose.

A star is a patch of white hairs in the center of the forehead.

A blaze is a streak of white hairs running down the face,
starting from the star.

A horse is bald-faced when the star and: snip are connected
by a broad blaze.

When the blaze does not run down the axis of the nose, it is
termed a race. ,

White hairs on the legs are almost always limited below by
the hoof. They are described by mentioning their upper limits:
white heels, white coronets, white pasterns. When the white
color extends nearly or quite to the knee or hock, it is termed a
white stocking (Figure 3). A white foot is, properly, one
where the hoof, as well as the hairs near it, is white.

A horse has black points when the mane, tail, and lower
legs are black. If the mane, tail, and lower legs are the same
color as the rest of the animal, he is self-colored. A horse is
light of the sort when he is paler than the average for the color.
It is usually a sign of constitutional debility.

A mane is roached when it is trimmed close on each side,
leaving a short, thin line of hair in the center about an inch long,
running the length of the crest (Figure 4). It is hogged when the
mane is cut closely throughout (Figure 3).

Beit ae

18 ELEMENTS OF HIPPOLOGY.

A tail is banged when it is cut square below the end of the
dock (Figure 2). It is thinned when it is shortened by pulling
and breaking, but not squared off (Figure 4). It is docked when
the dock and hair both are cut off from eight to eleven inches
from the root of the tail.

A brand is a mark burned in the skin of a horse, leaving a
scar of some definite design to establish ownership.

Clipping is the process of shortening the hair of the coat
by means of clippers.

Singeing is the process of burning long hairs in the coat
until they are the same length as the rest.

Wire cuts are the scars of wounds made by barbed-wire
fences.. They are characteristic in appearance, and frequently,
by their location, cast suspicion upon the soundness of the an-
imal. Usually the wounds causing them were only skin deep,
when the resulting scars are merely blemishes.

A rope burn is a scar or wound made by chafing the skin
of the fetlock by a rope. Like a wire cut, it is usually only
a blemish. \

The height of a horse is determined by measuring, in
hands of four inches each, the altitude of the top of the withers.
A full-grown horse, fourteen hands two inches high (written:
14 : 2”), or less, isa pony.

Generally speaking, a blemish is any irregularity that mars
the beauty or symmetry of a horse, while a defect is one that
reduces his usefulness.

The forehand of a horse includes that part in front of the
rider. The part in rear is termed the haunches.

Of a pair of horses, the near one is the left, the off one is
the right. The near side of a horse is his left side; the off side,
his right.

A sound horse is one that is not affected with any disabling
disease or injury; an unsound horse is one that is suffering

HLEMENTS OF HIPPOLOGY. 19

from any malady, acute or chronic, however slight, or that has
been disabled in any degree by disease or injury.

An acute disease is one attended by more or less violent
symptoms and coming speedily to a crisis, while a chronic ,
disease is one that continues a long time, mild as to intensity
and slow as to progress. An acute disease results in a speedy
recovery, or death, or it may assume a chronic state. A chronic
disease is difficult to cure, and yields only to long-continued
treatment. ee
3 The Law of Warranty.—When a horse is purchased, the

seller should furnish a bill of sale, setting forth the description
of the horse and guaranteeing certain things, as, for example,
that he.is sound; that he is sound and kind; that he is serviceable
for certain specific work, ete. |

This bill of sale is the new owner’s guarantee of title to the
horse. It also insures him against defects existing prior to the
date of sale.

A warranty does not go forward of the date of sale,
unless it explicitly states so.

If a person buys a horse that goes lame immediately or soon
after purchase, he can recover on the guarantee only by showing
that the horse exhibited the same lameness before the sale.
Similarly with a horse warranted kind that runs away or balks
after sale. Unless the new owner can establish similar vicious-
ness before the sale, he cannot recover damages from the former
owner.

This arises from the fact that all that can justly be ex-
pected from the seller is that he state truly in his warrant what

CHAPTER. At.

AGE, AS DETERMINED BY THE TEETH.

The value of a horse, after he reaches maturity, is propor-
tioned to the remaining period of his usefulness. It is, there-
fore, of importance to a purchaser to know approximately, and
without being compelled to rely on the testimony of others, the
age of the horse he is buying.

It is very easy for anyone, however little he may be familiar
with horses, to distinguish the young from the very old animal.
Signs of wear are apparent in the stiffened action, in blemishes
on the members, and, more than all, in the elasticity of the skin.
Aristotle says: ‘‘If, in pinching up the skin from the lips, it is
promptly retracted, the animal is young; if it remains wrinkled
for a long time, he is old.”

Because the coat hides the skin, those signs of age that the
skin betrays in hairless animals cannot be detected in the in-
tervening years between youth and old age. For our guide
during this period we must go to the teeth, which appear and
grow and change their shape according to laws that are fairly
regular.

Up to five years the teeth give very reliable information;
from five to nine this information is good; after nine the limits
of error increase rapidly, and little reliance can be placed on the
teeth as a sole means of judging age.*

*There are horsemen who claim to judge accurately the age of all
horses, solely by their teeth. Such a claim, while honestly made by
many competent horsemen of experience, is often not made good in
practice. The teeth do furnish an excellent suggestion as to the age
of the horse—good enough to protect the careful observer from impo-

sition—that is all that should be claimed for them by the amateur
horseman.

22 ELEMENTS OF HIPPOLOGY.

The back teeth, molars, are
six in number on each side of
each jaw; those in the lower jaw
are’shown in Figure 10.

In addition to these twenty-
four molars, another molar some-
times appears in front of the
others, more often in the upper
jaw than the lower, and rarely in
both jaws. These molars are ru-
dimentary and usually tempo-
rary, appearing before the colt is
a year old and usually disappear-
ing before he is three. They
sometimes remain indefinitely.
These teeth are usually called
wolf’s teeth, but are sometimes
called blind teeth, from a fan-
cied influence on the horse’s sight.

The molars are difficult to
examine on account of their loca-
tion, and their usefulness as evi-
dence as to age ceases at five,
dee when all the temporary ones_

The changes in the other teeth are quite regular up to that
age. Jor this reason, inspection of the molars to determine age
is rarely resorted to.

The inspection of the incisors, the twelve teeth in the an-
terior portion of the horse’s Jaw, is the usual means employed to
approximate the age of horses. In inspecting them, the fol-
lowing details are examined:

First: Whether they are temporary or permanent.

The common names for the incisors, naming them each way

from the middle of the jaw, are center, intermediate, and
corner.

ELEMENTS OF HIPPOLOGY. 23

When the foal is born none of the incisors have appeared.
About a week later the two center teeth are through the gums.
In a month the intermediates appear, and after eight or nine
months more, the corner teeth. These teeth are small, thin, and
white, and of little interest as a means of determining age to the
ordinary observer. Up to this time the colt’s very appearance
marks his infancy—he is leggy, small in the body and neck, his
~ mane and tail are woolly and characteristic in appearance. |

For the next year and a half, to the casual observer, these
teeth change but little; their grinding surfaces wear away, but
they retain much the same appearance they had at one year.
- Because these teeth appear while the colt is still drawing his
sustenance from his mother, they are called milk-teeth.

Between two and a half and three years, the center milk-
teeth have fallen out and permanent ones have taken their place.

When the horse approaches a given age—three, for instance
—he is said to be rising three; after he has passed it, he is three
off until he is three and a half; after that period, he is ris-
ie TOUT.)

The age of the colt at three is easily determined when we find
the center incisors permanent and the rest temporary.

At four the intermediate temporary teeth are shed and re-
placed by permanent ones, and at five the temporary teeth are
all gone.

Figure 11 shows very plainly the difference in appearance be-
tween the temporary (corner) and the permanent (intermediate)
teeth.

Simply by opening the colt’s lips the observer can tell his
age near enough for all ordinary purposes. As a rule, a horse
less than five is not mature enough to be put to hard work; his
development is not complete, and what would be quite suitable
employment for a mature horse would probably prevent the
full development of a colt and by so much destroy his future
usefulness.

26 ELEMENTS OF HIPPOLOGY. ~ Pe

Sometimes the temporary teeth are pulled to make the colt
appear older, and occasionally the corner teeth and intermediate,
especially in the upper Jaw, are shed at nearly the same > time—

about four. . However, this is not the rule. F
Second: The angle at which the teeth of the. two
jaws meet.

The younger the horse, the more nearly the ee, made by
the prolongation of the front faces approaches 180 degrees. This
angle becomes more and more acute as the horse grows older.
Compare the angle made by the outer faces of the upper and
lower teeth in Figures 11 and 12.

Third: Whether or not they meet accurately.

If the teeth do not meet accurately, the tables of the teeth
do not wear as uniformly as in the normal case and their ap-
pearance is not a good index of the horse’s age.

If the upper jaw is longer than the lower one, the upper
teeth will, when the mouth closes, project beyond the lower ones.
This malformation is termed parrot mouth. The contrary
case, much more rare, is termed undershot. ‘The cuts on the
opposite page illustrate each case. It is very difficult to ap-
proximate the proper age of horses possessing either of these
malformations, since the teeth, not meeting, do not wear away
according to the general rule.

The horse whose mouth is shown‘in' Figure 14 has the habit
of biting at the woodwork of his stall, “the picket-rope—anything
within his reach. This habit is known as cribbing, and is the
cause of the wearing away of the upper teeth. This animal was
known to be between ee and twenty when this picture
was taken.

Fourth: The appearance of their outer faces.

The teeth of a young animal show smoother surfaces (are
less stained and chipped on the edges) than the same teeth in
older horses. Young teeth are whiter than old ones, and have not
such pronounced deposits of tartar on the margins of the gums.
Compare Figures 15 and 16. |

Fifth: The shape of the corner teeth.

The tables of the teeth are the surfaces that meet when the
jaws close. When the permanent corner teeth come up, at
five, the profiles of their tables are right lines. The upper tooth
does not, usually, meet the lower tooth exactly, but projects
slightly to the rear. As the teeth wear off by grinding against
each other, the forward part of the upper corner tooth wears away
faster than the rear part, and a hook appears. This hook-like
appearance is characteristic of horses seven and older, IF THE
TWO CORNER TEETH DO NOT MEET THROUGHOUT. If they do, the
teeth will wear evenly, and the profile will remain a right line.
The hook is almost never present at five, is slight at six, and quite
pronounced at seven. Compare Figures 17, 18, and 19.

Sixth: The directionand
length of the teeth.

As seen in the cut, Figure 20,
the tooth in its original shape
curves more rapidly towards
its outer end. The shape of
the remaining portion of the
tooth is not altered as the tooth
wears off and is pushed for-
ward. The height of the mo-
lars remains fairly constant,
and thus the distance between
the jawbones at the outer
end also remains constant.

As the exposed ends of the
teeth lose their curvature and
the straighter portion of the
original tooth comes into view
with advancing years, they
meet farther and farther to
the front, and the visible por-
tion of the tooth becomes
longer. Contrast Figures 11
and 12. At the same time the |
teeth become narrower in di-

N ameter, and so appear more

closely bunched in the older
animals. Contrast Figures 18
and 23. The plumpness of the
gums is less in old horses than
in young ones. Contrast Fig-
ures 11 and 12. r

Seventh: The mark, the dental star, and the shape .
of the tables.

All the details above enumerated are preliminary to the ex-
amination of the tables of the teeth and confirmatory of what is
to be learned from them.

The structure of the incisors is the same for all: A central
cavity, the pulp cavity, containing the nerves, blood-vessels,
and secreting tissues, is contained in the axis of the tooth. Sur-
rounding this pulp cavity is dentine, a dense and ivory-like sub-
stance, forming the body of the tooth. This dentine in the per-

fect tooth

hollow in

hard, and

of varying thickness. The depression in the tooth soon becomes
discolored from, the débris of decomposing food lodging there. The
enamel that crowned the tooth at its appearance soon wears off, but
the enamel on the outside of the tooth and that lining its central
depression still shows in cross-section on the table of the tooth.
The blackened spot in the center of the tooth, with its surround-
jng ring of white enamel, is called the mark, and is present in
every permanent incisor for about three years after its appear-
ance. By this time, in the ordinary case, the grinding of the
teeth against each other has worn off that part of the tooth con-

32 ELEMENTS OF HIPPOLOGY.

taining the depression, but for another year the discoloration of
the body of the tooth, due to the chemical action of the contents
of the depression, is still more or less visible.

As the tooth wears down and exposes the pulp cavity, ie
secreting tissues deposit dentine to fill up the cavity, to protect
the nerves and blood-vessels from injury. The dentine so formed
is yellower in color than the original dentine of the tooth, and as
the tooth gets more and more worn down, assumes somewhat
the form of a star, hence its name, dental star. At first this
new dentine appears as a yellowish line in front of the enamel of
the mark. This is because the pulp cavity is spread out quite.
thin near the end of the perfect tooth. It narrows and broadens
deeper in the tooth until its final shape is circular. The circular
shape is not found until the horse is about twelve, although this
rule is extremely elastic.

At three or four the observer can be sure enough of the
horse’s age without looking at the tables, but after that |
should be consulted.

At five the horse’s mouth presents quite positive ever
of his age. Looking at the outer faces of the teeth, they appear
smooth and clean. The edges are sharp; there is no hook in the
upper corner teeth; the gums are plump; the horizontal and
vertical axes of the teeth are not far from equal. Looking at the
tables, the mark is found to be clear in all the teeth; the center
and intermediate teeth show tables nearly rectangular in shape,
and the axis of the tables at right angles to the jawbone is nearly
twice as long as the other one. But it is in the corner tooth that .
the surest evidence is found. As the other incisors appear, at
three and four, the mark is entirely surrounded with enamel, but
the corner tooth comes up as a shell, with the inner wall missing,
and not until the tooth has been in use for from six to nine
months is the outer portion of the wall worn down to the level of
the inner portion. This peculiarity of the corner tooth at five,
once seen, should never be“mistaken.

ELEMENTS OF HIPPOLOGY. 33

_ At six the hollow of the mark has been worn off the tables
of the center teeth, but the enamel is still there; it is discolored;
and sometimes appears not very different from the marks in the
other teeth—a little less dark and its margin less pronounced. |
The mark is plainly present in the intermediates and corners,
and the wall of the corner tooth is up all around. The tables of
the teeth at six usually lose something of the rectangular shape,
becoming more rounded on the longer sides.

Looking at the exterior faces of the teeth, the hook is be-
ginning to appear and the teeth are losing their fresh, clean ap-
pearance. ‘There is nothing positive to go by in the six-year-old
mouth, except the presence of the mark in the intermediates
and corner teeth, and even this is sometimes misleading.

} At seven the yellowish line of the dentine that has filled up,
the pulp cavity shows quite plainly in the center teeth and may
show in the intermediates. The mark is gone from the center
teeth and faint in the intermediates; it shows quite plainly in
the corners. The tables are much more rounded in outline. The
exterior aspect of the teeth is quite changed; they are much
longer and their angle of meeting is more acute. The hook is
now plainly visible, except in those mouths where the posterior
corners of the corner teeth meet exactly, and it is the presence of
this hook, together with the presence of the mark in the cor-
ner teeth, that makes the seven-year-old mouth fairly easy to
interpret.
Dishonest dealers frequently rasp off the hook to make the
horse appear younger than he is.

36 ELEMENTS OF HIPPOLOGY.

FicuRE 26.—TuHEr Tapies at NINE.

The central enamel is still present in all the teeth, although
the discolored portion is usually worn off in the center teeth.

At eight the mark is gone from all the teeth, although the
corners are still discolored and the central enamel is found in all
of them. The line of the dental star is better defined in the
center teeth. The tables are more rounded than before and the
line joining their centers is a flatter curve than in the younger
mouths. A comparison of Figures 22, 23, 24, and 25 will show
the gradual flattening of this curve.

Viewed from the side, the angle of meeting of the teeth has
erown much more acute than at seven.

The principal test to be used in distinguishing between an
eight and a nine-year-old mouth is to see whether the central
enamel is gone from the center teeth. [If it is still present, the

ELEMENTS OF HIPPOLOGY. 37

horse is probably eight; if it is worn off, he is probably at least
nine. Just as the presence of the temporary teeth shows the
colt-age, so the absence of the central enamel shows that the
horse is more than eight—that he is “‘ past telling’’ with any degree
of certainty. It is much more difficult, even with this central
enamel as a test, to distinguish between the eight- and the nine-
year-old horse than it is to tell a four-year-old from a five-
year-old.

In fact, it must be impressed upon all that there is no in-
violate rule for the growth and wear of the teeth. Differences
in the density of the dentine, differences in food and method of
feeding, or bad stable habits, will cause teeth to vary widely in
appearance in horses of the same age.

At nine the tables of the center teeth are quite rounded, the
dental star is much more rounded in them than before.

From nine on the indications of the horse’s age become in-
creasingly Jess reliable. Mayhew says: ‘The greater the num-
ber of years, the more difficult it is to arrive at the exact determi-
nation of the age. After the twelfth year there is but little prob-
ability of judging it correctly; after the sixteenth, all is con-
fusion, for there are no positive signs that will enable us to give
a definite opinion upon this point, and it is better now to be
cautious, or remain silent.’’*

The amateur had better go farther than that and refrain
from any positive judgment after nine.

When the dental star becomes round and the tables tri-
angular, the horse is probably twelve or more; and when the
necks of the teeth become small and widely separated, he is ap-
proaching very near to the end of his period of usefulness.

In judging horses for age it is best to proceed leisurely.
Open the horse’s lips, and view first the faces from the side.
Look for temporary teeth; see if the teeth meet evenly; see if

the upper corner tooth has a hook; observe the plumpness of the

gums; the edges of the teeth, to see if they are chipped; their —
margins near the gums; for tartar. Look next at the front faces
of the teeth, and compare the relative lengths of the axes of the
center teeth, remembering that the greater the disparity in these
lengths, the older the horse. Next, open the horse’s mouth, and
look at the tables. The first thing to notice is the table of the
corner teeth to see if the wall has grown up on the inside; look
for the mark, the shape of the tables, the dental star, the curva-
ture of the line joining the centers of the tables, and the slope of
the inner faces of the teeth. If the mark is gone from all the
lower teeth, look for it in the upper. The horse that has the
mark in all his upper teeth is probably not very old—perhaps
between nine and thirteen, probably not more than the latter.
Beware of triangular tables; they are never found in the young
horse—always in the old.

FIGURE 28.—AN ABNORMAL MoutH—MARK CLEARLY VISIBLE IN ALL
THE TEETH AT TWELVE.

Having applied all these tests, reconcile all discrepancies as
nearly as may be and make the estimate modestly, remembering
that to be cock-sure in an estimate of a horse’s age from the ey-
idence of his teeth alone, is a sign of ignorance.

Figures 16 and 28 show the front view and the view of the
tables of a horse known to be twelve at the time the photograph
was taken. He was a restless horse, who objected to a scrutiny
of his mouth, and the first hasty glance at the tables showed all
the marks present and the wall of the corner teeth fully grown
up. An observer, satisfied with that evidence alone, might say
once, “Six years old’’; but a more careful look at the shape .
of the tables would render that estimate very doubtful, while a
single glance at the stained and chipped exterior, covered with

40 ELEMENTS. OF HIPPOLOGY.

tartar, the long vertical axis of the center teeth.and their slope,
would confirm the error.

A horse’s teeth are said to be bishoped when a_hole in the im-
itation of the mark is burned in his teeth. As the false mark
cannot be surrounded by the enamel of the genuine one, and as
the other tests for confirming the evidence of the mark will nec-
essarily fail, the deception is easy of detection. It is a trick
rarely resorted to.

The tushes, or canine teeth, usually appear at about four,
are usually perfect at five, and show greater or less signs of
wear after that.

They usually are absent in mares. This fact, and the un-
certainty of the time of their appearance and their rate of growth,
makes them almost useless as an aid to the determination of age.
A bright, clean tush, showing little signs of wear, is a good index
to a young horse; while a flat-topped, chipped, and yellow tush
is a usual accompaniment to age. It is not wise to place much
more reliance upon them.

CEPA ETE RS LEP:

INFLAM MATION.*

In all the higher animals the tissues (bones, muscles, cap-
sules, ligaments, tendons, glands, etc.—in brief, all parts of
the body) are nourished and kept alive by the circulation of the
blood. Blood consists of a pale-yellow fluid, carrying in it
myriads of white and red semi-solid bodies called corpuscles.

The red corpuscles, under conditions of health, very largely
outnumber the white ones. They are without volition and float
along, charged with oxygen to support life in the cells composing
the tissues.

The white corpuscles have a volition of their own; they act
as the scavengers of the tissues. They have the power of ab-
sorbing and of digesting other micro-organisms, and thus protect
the body from disease germs.

Blood, leaving the heart through the aorta, is carried by
the arteries, branching and rebranching, to arterioles, which
terminate in capillaries. The arteries and arterioles have im-
pervious walls, but the capillaries, subdividing into a veritable
lace-work, so as to reach the neighborhood of every element,
have cellular walls, which permit the passage through them of
the fluid and solid parts of the blood. In the capillaries the flow
of blood is uniform, when in a state of health, towards the vein-

while the white ones, due to a certain volition of their own,
float along near the walls of the capillaries. The nutrition, re-
ceived into the blood from the digestive apparatus, as will be
shown later on, replaces worn-out tissues. The oxygen of the
red corpuscles is consumed in maintaining the heat of the
body, and the blood flows on, taking with it the dead cells of
worn-out tissues, the red corpuscles, largely deprived of their
oxygen, and the white corpuscles, with their burden of absorbed
germs, through the veins in a steady stream to the heart. From
there it is pumped into the lungs, blue in color and exhausted of
vitality, to be vitalized with oxygen and relieved of its waste
matter. From the lungs it goes back to the heart again, purified
and enriched, to repeat its function. As the result of repeated

ELEMENTS OF HIPPOLOGY. 43

experiments, it has been estimated that it takes, in the horse,
thirty-one seconds for the blood to complete this round of
circulation.

If the flow of the blood in the capillaries, for any reason,
is impeded, the white corpuscles pass through the walls of those
vessels and

*Let it be understood that this discussion is the merest outline of
the wonderful processes of nourishment and destruction of living tis-

44 ELEMENTS OF HIPPOLOGY. —

Inflammation itself may be described as the perverted
nourishment of any part. An injury, the presence of a foreign
body, or some abnormal quality of the blood itself chokes the
flow of blood through the capillaries and the veins. The heart
keeps pumping blood into the affected region, and there is no
corresponding drain. This excess of blood is forced through the
walls of the capillaries, the tissues become overcharged with it,
and the cells and white corpuscles, over-stimulated, begin to
multiply. Crowding together, by their own numbers they soon
deprive each other of the necessary nourishment, and they die.
Other germs, less beneficent than the cells and white corpuscles,
if present in the tissues, or if introduced by the cause of the in-
flammation, take this occasion to multiply, to destroy other cells,
and to die themselves in turn. These dead cells, corpuscles, and
germs, suspended in. the fluid of the blood, form the whitish,
malodorous substance known as pus.

Figure 31 shows a section of the uninflamed wing of a bat,
much less highly magnified than in the preceding cuts. The en-
largement is not enough to show the capillaries connecting the
arteries and veins. The same spot in the membrane was then
wounded with a needle, inflammation set in, and Figure 32 shows,
under the same microscope, the enlargement of the capillaries,
due to the increased flow of blood, and the accumulation of the
corpuscles.

Often there is an unnatural accumulation of blood in any
part, caused either by an increased flow of blood to the part or
by an obstruction that prevents the free exit of the blood through
the veins from the tissue affected. This is called congestion of
the part. In either case there is an increased supply of blood,
sues; that it is very, very inadequate. The term “corpuscle”’ is
wrongly used to describe all the bodies carried in the fluid of the
blood and “‘cell’’ to indicate the atoms of which the tissues are built.
“Germ” is used to vaguely designate those living micro-organisms

that laymen should be willing to dismiss with the knowledge that one
must be very wise to understand them.

and, as a result, increased combustion (oxidation), manifested by
heat, and augmented nutrition, manifested by swelling.

Pus may be confin-
ed by limiting mem-
branes provided by
Nature to prevent the
migration of the pus
to sound tissues.
Such a sore is termed
an abscess. If the
pus escapes externally
from an abscess and
the channel of escape
is similarly lined by
a limiting membrane,
the channel is termed
a sinus.

Pus forming with-
out such a limiting
membrane invades the
surrounding tissues
and destroys them.
Such a sore, when open
is called an ulcer.

Any injury, or
wound in which pus
forms is said to sup-
purate or to be in-
fected. If the pus is
absorbed into the cir-
culation while the in-
jurious germs are still

active, abscesses are sometimes set up in organs distant from
the original injury; at other times the infection attacks the

corpuscles of the blood itself, destroying them. In either case
blood-poisoning is said to have set in.

Sometimes the affected part dies. This is said to be mor- -
tification or gangrene in soft. tissues, and necrosis in bone.

The local signs of inflammation are redness of varying
degree, pain, swelling (except in bone), and heat. The gen-
eral symptoms are fever and loss of condition. In aggravated
cases the vital organs gradually suspend their meee and.
death from exhaustion results. |

The treatment of inflammation is the same in principle
whatever be the part inflamed. Inflammation is hypernutri-
tion, attended by excessive blood-supply. Any agent which will
reduce the blood-supply and prevent the excessive nutrition of
the elements of the part will serve as a remedy. The means
employed may be used locally to the parts, or they may be con-
stitutional remedies, which act indirectly.

In the treatment of sick horses, as in the treatment of ailing
human beings, the administration of drugs should be sparingly
resorted to by amateurs. Proper feeding and watering, cleanli-
ness and sanitation in stables, and careful nursing, will keep
veterinary bills down.

Indiscriminate use of drugs is seldom beneficial or
economical.

In all cases of inflammation, seek first to remove the
exciting cause. This may be some foreign substance, which
irritates the animal directly, or it may be some decomposing
substance, full of disease germs, in the stable.

Rest is the next requisite. Motion induces an increased
flow of blood, and blood supplies the food for inflammation.
The patient should be in a darkened stall, free from noise or
~ anything that will excite him.

Cold and hot applications reach the same end by opposite
means. Cold applications—ice-bags, cold bandages, fomenta-
tions, etc.—contract the blood-vessels and soothe the nerves,

ELEMENTS OF HIPPOLOGY. 47

while warm applications, either wet or dry, increase the circula-
tion by expanding the blood-vessels, and so put an end to the
congestion existing in the inflamed part.

In cases of chronic inflammation, the surrounding tissues
may have been left so weakened by it that they do not perform
their functions properly. Then they need stimulating to allow
them to recover strength by the application of liniments con-
taining mild stimulants, or by massage. If this does not bring
about satisfactory results, a veterinarian should be consulted.
Blood-letting, the use of severe counter-irritants—blistering or
firing—or the use of strong tonics or stimulants, should not be
attempted by amateurs.

In all cases of inflammation it is of the greatest importance
to limit the diet to small quantities of easily digested foods,
freshly prepared and frequently offered. [ood should not
be permitted to remain before the patient long. If refused or
only partly eaten, remove it, clean the manger thoroughly, and
offer a fresh supply in a couple of hours. No invalid is more
capricious about his food than a sick horse.

When the tissues have been destroyed by inflammation,
they are replaced by the formation of new tissues, different from
the old in appearance and structure. This new tissue is called
a scar.

The relation of the bones to the soft tissues of the head and
neck is shown in Figure 33.

The face is that part of the head seen from direction in front,
between the nostrils and the forelock.

The forehead includes that part of the face between the

The brain of a horse is very small, about the size of a polo
ball. To destroy a horse by shooting, aim at the intersection of
two imaginary lines drawn from each eye to the diagonally op-
posite ear. If the revolver is held at right angles to the plane of
the face, a shot thus placed will instantly and painlessly destroy
the animal.

In the well-bred horse the head should be of medium size,
lean, wide between the eyes, finelygchiselled and terminating

wide at the nostrils. It should be wide from the eye to the
angle of the jaw; wide under the jaw, wide at the base of the
skull (where the head and neck join). The nose should be
straight; the nostrils large, wide, and without many hairs.
The fleshy borders of the nostrils should be thin, firm, and
sensitive.

The ears should be small, fine, and nervously alert. In
changing position from front to rear, they should describe small
circles. They should not droop to right and left.

Horses possess very acute sense of hearing, and the ears,
large and funnel-shaped, locate the direction of the origin of
noises by rotating until the maximum sound is received. “As
flight (running away) is the horse’s chief natural means of self-
protection, he has great ability in turning his ears to the rear
without altering the forward position of his head. In a pitched
battle with carnivorous enemies, wild horses employ their eyes
and ears, as a rule, in a backward direction, while using their hind
feet as weapons of assault; and even when making a forward
rush at an enemy, they almost always ‘put back’ their ears.
The fact of a horse looking backwards is at once made manifest
by his showing ‘the whites of his eyes.’ These actions of eyes
and ears are so closely connected in the horse with fear and
anger that he often performs them without any direct incentive
when influenced by these feelings. Hence, all experienced horse-
men regard an unprovoked putting back of the horse’s ears and
showing of the whites of his eyes as a reliable warning to ‘look
Out as

It is to be remarked that the signs of warning above men-
tioned are usually accompanied by a contracting and flattening
of the nostrils.

pearance, when in repose, is sleepy and lymphatic; when in ac-
tion, ouey and unwilling.

The eyes should be full, clear and bright, and symmetrically
placed. They should not be watery; the pupils should be black

FIGURE 39.—THE EYE, IN CROSS-

The eye is a sphere, con-
taining two chambers (Fig-

is filled with aqueous hu-
mor; the other, many times
larger, with vitreous hu-
mor. The lining of the pos-
terior chamber of the

the crystalline lens. {n front of the anterior chamber is the
cornea. The cornea, crystalline lens, and the two humors, are
perfectly transparent in the healthy eye. The crystalline lens
is screened by the iris, a sensitive membrane that is pierced
at its center by the pupil. The iris is capable of expanding and
contracting, and so can regulate the supply of light admitted to
the retina through the pupil.

Looking closely into the sound eye, a fringe of sooty, spongy
aspect will be seen, attached to the edge of the iris, heavier above
than below. It is called the corpora nigra, and is a provision
of Nature to partially absorb the light entering the eye and to
supply the protection given to the human eye by the overhanging
eyebrow.

The pupils should dilate and contract equally and freely,
The iris should be of uniform color. Frequently there is lack of
color in the iris. The visible effects-of this condition is the
whitish ring surrounding the pupil, known as wall-eye.

An opacity of the cornea is a positive defect that limits the
field of vision of the horse. Such a horse is usually a shyer,
nervous and undesirable for any sort of fast work.

The wall-eyed horse must not be confused with the horse
that ‘‘shows the white of his eye,”’ already discussed. In the
ordinary case the white does not show, but an excitable, nervous
horse, suffering from timidity or fear, will open his eyes unduly
wide and so show the whites of them. It is a sign of nervousness
or vice, or both, and, while often merely the result of brutal
treatment, is always an undesirable quality.

As a protection to the eye, to remove foreign particles that.
adhere to its outer surface, Nature provides the haw, a thin mem-
brane that, in a restful state, appears as a thin fold at the inner
angle of the eye. When the eye is irritated by dust, hail, chaff,
or the like, the ball is slightly withdrawn into the socket and the
haw is stretched across the eye, removing weshanically the ir-
ritant, assisted by a profuse flow of tears,

Blindness is common among horses. If it results from an
injury to the external eye or from cataract, it is easy of discovery;
if from disease in, or destruction of, the optic nerve, it is not
sO apparent.

A cataract shows itself as a milky opacity in the interior
of the eye. Its seat is in the crystalline lens or its coverings.
What is known as the candle test is the surest method of de-
termining whether an opacity in the eye is or is not a cataract.
In a partially lighted place a lighted candle is held in front of the
eye. If the eye is perfect, three images will be seen—one, the
front one, erect, is the reflection from the outer surface of the
cornea; the second, also erect, is the reflection from the front
surface of the crystalline lens; the third, inverted, is the reflection
from the back of the lens. As the candle is raised or lowered, the
first and second images go up or down, the third moves in a con-
trary direction. Ii a cataract is present, the inverted image is
blurred, or wanting altogether; if the trouble is in front of the
lens, there will be but one distinct image.

A good preliminary test for blindness is to raise the hand
from below to the level of the eye and near it, then to withdraw
it, but not so rapidly as to cause appreciable air-currents. If
the horse does not wink or dodge, there is grave suspicion cast
at once on his vision in that eye.

In order to give lightness to the head, and at the same time
to afford room for the attachment of the various muscles of mas-
tication, some of the bones of the horse’s face are hollowed out,
leaving blind cavities, opening only downward. These cavities
are called the facial sinuses, and seem to have no function,
except that mentioned.

The neck includes seven of the vertebre of the spinal
column. The muscle that moves the foreleg forward is attached
to the head and the first four of the neck vertebree; the longer this
muscle is, the greater will be its contractibility and consequent
leverage on the bones of the foreleg and the stronger will be the

54 ELEMENTS OF HIPPOLOGY.

action of the limb. In saddle-horses, nothing is to be gained by
increasing the weight of the neck muscles beyond that necessary
to give a sure and graceful carriage to the head and a quick and
free forward swing to the front leg. The neck should, therefore,
be long and slender, without too marked a crest. (Figure 1.)
The neck, at its upper end, should be spare and flexible. This
condition, together with width between the Jaw-bones, is neces-
sary in saddle-horses; without it, they are stiff and unhandy.

The horse shown in Figure 40 is an example of an otherwise
good horse, spoiled by too much flesh in the neck. He has the
neck of a stallion, and the inference is that he was gelded com-
paratively late in life. Castration is usually performed when the
colt is about one year old. If the operation is done, as is some-
times the case, when the colt is very young, he is apt to be under-
developed in the forehand when he is matured. If the time of
castration is postponed until two, three, or later, the development
of the forehand will more and more resemble that of a stallion.
The operation is more easily and more safely performed on a
young than on a mature animal.

The excess of flesh on the crest of the horse in Figure 40—
thirty pounds or so—makes it impossible for him to handle his
head and neck easily, and he is hard to turn or stop quickly in
consequence. He is not a good drill-horse, although he has very
comfortable gaits and is kind and willing.

The horse shown in Figure 41 is a saddle-horse ‘‘de luxe.”
His neck is thick at the base, but it is light at the crest and tapers
nicely. He should be able to control it easily.

A ewe-necked horse is one whose crest is concave.

The nasal membranes should be smooth, moist, of uniform’
color, and of a bright appearance. Any dullness of these mem-
branes, any discharge from the nostril, and any ulceration, or
scars of old ulcers, should be viewed with gravest suspicion in
examining a strange horse.

Glanders is a
highly contagious
disease of germ ori-
gin, incurable, and,
in this latitude,
usually fatal. . It
is, of all diseases
incidental to the
horse, the most ma-
lignant and the
most to be dreaded.
It is highly conta-
gious to human be-

‘ ings also, and nec-

essarily fatal to
them. In dealing
with a case of glan-
ders, the greatest
care should betaken
to protect one’s self
from the germs.

If the glanders
germ attacks the in-
ternal organs of the
horse, the disease is
known as glanders;
but if it attacks the
skin or the vessels
of the skin, the
disease is called
farcy.

Glanders usually
manifests itself by a

56 ELEMENTS OF HiPPOLOGY.

clear, watery discharge from one nostril, lighter in color
than in the case of a common cold. ‘A singular char-
acteristic of glanders is that it generally attacks one nostril
only, and that is the left one; only a few cases having occurred
where it commenced in the right nostril. Mr. Dupay, a cele-
brated veterinary surgeon, and director of this school of sur-
gery at Toulouse, mentions that out of eight hundred cases of
glanders, which occurred during his practice, only one was
affected in the right nostril.”’ - |

Farcy manifests itself in small tumors, soft at first, then
breaking into an ulcer. ‘‘The farey buttons occur most fre-
quently.on the side of the lips, on the sides of the neck, the
lower part of the shoulders, the inside of the thighs, or the out-
side of the legs, but may occur on any part of the horse.”

Farcy is always accompanied by the internal form of the
disease, although the latter may not be manifested by the nasal
discharge.

In order to discriminate between glanders and other diseases of
the nasal membranes, the mallein test is frequently resorted to.
Mallein is made by exposing a pure culture of the glanders germ
to dry heat sufficient to kill the germs. This dead culture is then
treated chemically to preserve it and is injected hypodermically
under the skin of the neck, usually, of the suspect. His tem-
perature is taken twenty-four hours before the injection and
again at the time of the injection. It is then taken every three
to six hours for forty-eight hours afterwards. If the place of in-
jection becomes materially inflamed and remains so for from two
to five days, with an inflamed spot at least five inches in diame-
ter, and a persistent rise of temperature of two degrees or more
is noticed, the suspicion is fairly well confirmed. The animal
should then be allowed to remain under observation in isolation
fora month. If now the test is applied with similar results, the

ELEMENTS OF HIPPOLOGY. 57

animal should be killed and burned and all his equipment and
surroundings burned or thoroughly disinfected. If, however, on
the second test he does not respond, a third test should be made
at the end of another month, which may safely be regarded
as final.

Any horse presenting a discharge at the nostril should be at
once isolated, and his stall and all his equipment thoroughly
disinfected. |

Nasal gleet is a chronic diseased condition of the nasal
membranes and of the linings of the facial sinuses. It is the
result of neglected colds (bad stable management), or ulcerated
teeth, and is a stubborn disease to cure. It is marked by a dis-
charge from the nostrils, one or both, offensive odor, and fre-
quently by no other outward symptom. Nasal gleet and glan-
ders are frequently mistaken, one for the other.

Influenza is a highly infectious disease, usually of brief
duration. True influenza usually spreads in waves of contagion
over large areas. It is easily spread and difficult of treatment.
The patient is stupefied, hangs its head, is not easily roused; the
eyes become inflamed and tears flow profusely. It is frequently
followed by disabling complications.

Catarrh is inflammation of a mucous membrane. It is
called by various names, depending on its location.

Cold in the head is an inflammation of the mucous mem-
brane of the nasal passages and neighboring regions. It is man-
ifested by ‘dullness, fever, a watery discharge from the nose, and
sometimes by an inflamed condition of the eyes. The patient
should be exercised very little, placed in a loose stall, well ven-
tilated, but free from drafts. Like the human disease of the same
name, the watery discharge, as the disease progresses, becomes
thicker and of a whitish color. Colds in the head ought not to be
neglected, nor should animals so affected be put to severe work
until cured.

5S HLEMENTS OF HIPPOLOGY.

Strangles, or distemper, also an infectious disease, mani-
fests itself by catarrhal symptoms and by enlargements of the
salivary glands lying near the angle of the lower jaw (the parotid
glands). In the general case these glands suppurate and make
an abscess easily recognized. An animal usually has this disease
but once, and rarely after becoming of age. The danger from
strangles is in the permanent thickening of the air-passages and
permanent injury to the breathing apparatus in consequence.

Poll-evil is an obstinate abscess on top of the head. It
results from an injury received there, which sets up an inflama-
mation that develops into an abscess. The muscles of the neck,
in the region of the poll, extend downward and backward. Pus
can easily burrow in between them and follow the course of these
muscles. Since, from its position, such an abscess cannot readily
drain its pus unless artificial drainage is provided, the pus will
work down into the sound tissues, infecting them deeper and
deeper. Any abscess where natural drainage is not possible is
termed a fistula. Like other fistulas, poll-evil is the result of
neglect.

Blind staggers, or congestion of the brain, is a brain
disease, similar to apoplexy. A horse affected with it will fall
down and struggle about in a spasmodic fashion, injuring him-
self in his spasm and threatening injury to any other animal near
him. It is a not uncommon disease, and is liable to recur at any
time. Relief is obtained by blood-letting. The jugular vein is
opened, and, after a sufficient amount of blood is drawn, is closed
again, leaving a scar of operation, usually not hard to find and
always worth looking for.

The jugular channel is well shown in Figure 8. It isa
groove on the lower margin of the neck. By rubbing the thumb
briskly several times down the channel with considerable pressure
and then pressing hard at the lower end of the channel, the
jugular vein will be closed by the pressure. It will fill rapidly
from above with blood and will become distended.

ELEMENTS OF HIPPOLOGY. 59

The operation of blood-letting is sufficiently simple and safe
to warrant any horse-owner to attempt it in cases of blind stag-
gers or congestion of the lungs in emergencies when professional
skill is not available. The flow of blood from a vein is easily
controlled. By tying a stout cord around the base of the neck
tightly, the jugular veins will be compressed enough to dilate
them, when they are easily seen. The fleam-blade of a farrier’s
knife is used. The point of the fleam is laid near the vein and is
driven into it by a sharp blow of a stick on the back of the fleam.
If the vein-wall is cut, the blood will flow freely in a constant
stream. It should be caught and measured as it flows. From
two to four quarts should be drawn—never more than four—
depending on the size and condition of the horse. A large, fat
_ horse will stand the loss of more blood than a smaller horse in
thin flesh will.

The vein can be closed by sticking a pin through the walls of
the vein at right angles to the cut and then winding horse-hair
or strong linen thread around the ends, figure of 8 fashion.

This method of closing wounds is a very useful one to re-
member. A horse whose skin has been cut by barbed wire or by
other means can be saved an ugly blemish, if the edges of the
wound are at once pinned together, placing the pins an inch or
so apart, and then lacing horse-hair or thread around the ends
of the pins. |

In the jugular wound the pins should be left in only three
or four days. The wound in the skin can be kept open by put-
ting a plug of oakum or absorbent cotton in it until the pins
are withdrawn.

Blood-letting should be resorted to, without professional as-
sistance, only in extreme cases—when it is evident that the
animal will die unless relieved.

CHAPTER WwW

‘BITS—THEIR ACTION, INFLUENCE, AND
PROPER USE.®*

A bit is an instrument devised to convey instructions
to the horse from his rider in accordance with a set of sig-
nals concerning his guidance and control, whose separate
meanings he has been taught to know.

The perfectly trained horse that has a perfect temper needs
a bit that conveys these instructions without pain. Such horses
are, unfortunately, rare, so bits must be devised that not only
convey instructions as to gait and direction, but that are capable
of inflicting pain when the temper of the horse inclines him to
disregard these instructions.

The point of application—the seat—of the bit is on the bars
of the horse’s jaw, about one-third of the distance from the tushes
to the molars (Figure 42).

Figure 43 shows a simple bar bit in its normal position on
the horse’s jaw.t The horse’s tongue lies in the opening be-
tween the two rows of teeth, under the bit, and, at rest, fills the
space under the bit and partially supports it.

*An effort is made here to describe only the action of ordinary
bits in common use, on normal mouths. The subject is a very broad
one, and must necessarily be briefly touched on here. -Captain M.
Horace Hayes’ admirable work, “ Riding and Hunting,” contains an
exhaustive discussion of this subject.

The author is indebted to Major Edwin St. J. Greble, 3d Field
Artillery, for much that is contained in this chapter.

+The same bone furnished the subject for this picture that was
used in Figures 42 and 44. To make Figure 43 and in Figure 44 the
bone was set at an angle, so that the bearing of the bit would show
as if seen from the front.

ELEMENTS OF HIPPOLOGY. 61

The two ridge-like"portions of the bone of the lower jaw be-
tween the molars and the tushes are called the bars, and form the
points of application for the bit.

As regards their action
on the horse’s jaw, bits are
classified as bar, snaffle,
and curb bits.

A bar bit is an unbroken
bit that acts, without lever-
age, directly on the horse’s
jaw, as in Figure 48. The bar
bit is supported partly on the
bars of the horse’s jaw and
partly on his tongue. This is
tough, leathery, and _ insensi-
tive. When the pressure of
the bar bit on the horse’s jaw
becomes painful to the bars,
he relieves the pain by thrust-
ing his tongue further under
the bit, thereby lifting it from
the bars and transferring the
pressure to his tongue.

To nullify this action of the
: tongue and still have a bit that

bit, and the resulting bit ig called a snaffle bit.

By pulling on the reins of a snaffle bit, a pincer action is de-
veloped by the closing of the angle between the halves of the
mouthpiece. This raises the hinge, lifting the mouthpiece off
the tongue, and applies pressure to the bars in a way impossible
of relief by the tongue.

The curb bit (Figures 47 and 48) is a bit operating on an
entirely different principle from the two other kinds just dis-
cussed. In the curb bit the force exerted by the pull on the rein
is increased in intensity by the leverage of the bit, and the pos-
sibility of inflicting pain is greatly augmented. |

The curb bit consists of two cheek-pieces with a mouth-
piece connecting them at such a point that the upper branch of
the cheek-piece will be about half the length of the lower one.
This ratio is by no means fixed, however. The upper branch is
usually between one and a half and two inches in length. The
mouthpiece should be large in diameter. It has a curved central
yortion,* called the port. The object of the port is to take

ELEMENTS OF HIPPOLOGY. 67

pressure off the tongue, when the bit is in use, and to localize it
on the bars. The port, when the bit is at rest, lies on the tongue.
When the bit is used, the port revolves upward and forward,
away from the tongue, with the result that the insensitive tongue
is freed from its influence. At the upper ends of the cheek-
pieces are rings for the attachment of the curb-chain. This chain
should be so adjusted that, when it is brought into use, it will le
in a smooth depression of the jaw-bone, called the chin-groove.

Figure 49.—THe UnbER SIDE or THE LOWER JAW-BONE.

The chin-groove is the rounded portion of the jaw-bone
just forward of the angle of the V. In health, it is smooth and
rounded, and admirably fitted to receive the pressure of the
curb-chain without injury to itself. The two branches of the
jaw-bone are very thin and sharp on the under side, where they
unite to form the chin-groove, and it is, as will be seen, highly
important that the curb-chain should fit into the chin-groove,
and not lie on these sharp bones.

There should be loops on the posterior edges of the cheek-
pieces, half way from the rein-rings to the mouthpiece, to attach
the lip-strap to. This strap is often necessary to prevent the
horse from getting the lower branch of one of the cheek-pieces

68 ELEMENTS OF HIPPOLOGY.

between his teeth or lips, and so defeat the object of applying
pressure to the sensitive bars.

The principle of the curb bit is a very simple one. The
power is applied by a pull on the reins to the lower ends of the

Figure 50.

cheek-pieces. The point of the horse’s head to which this power
is transmitted depends upon the adjustment of the bit and curb- —
chain. If the curb-chain is too loose, the bit will revolve around
the mouthpiece as a fulcrum, and the cheek-pieces of the bridle

ELEMENTS OF HIPPOLOGY. 69

will receive the load and apply it to the poll. This tends to bring
the horse’s head down. The curb-chain will lie in a plane nearly
parallel to the plane of the cheek-pieces of the bit, and but little
force will be applied to the bars or to the chin-groove. The bit
will slip up in the horse’s mouth, and will be held either by the
lips or by the molars. Such a bit is said to fall through, as in
Figure 50. :

The objection to having the curb-chain too loose is that the
power of the bit to restrain the horse, because of the pain it
inflicts, is lost to the rider.

The power is always applied to the curb bit at the lower end
of the lower branch. Whether the bit is a lever of the first
or second order will depend on where the horse feels the
most pain when power is applied.

If the chain is twisted so that it does not lie smoothly in the
chin-groove, if it slips up on the sharp edges of the jaw-bone, or
if it pinches the lips, the curb-chain will hurt the horse more than
the mouthpiece does, and the lever will be of the second class.
This is, of course, undesirable. The horse will try to get away
from the curb-chain by throwing his head forward, and a “‘hard-
mouthed”’ horse is the result.

If the curb-chain fits smoothly in the chin-groove, if it is
not so tight as to pinch the lips at all times, orso looseas to let
the bit fall through, a pull on the reins will cause the mouthpiece
to hurt the bars more than the chain hurts the chin-groove.
The fulcrum will then be at the upper end of the cheek-piece,the
weight will be applied at the bars by the mouthpiece, and a lever
of the second class results. This is the proper adjustment of the
curb-chain, and is what should be sought for.

When the bit falls through, the mouthpiece is slid up along
the bars to find a fulcrum at the corners of the horse’s lips or
against the molars. It often happens that the lips, that have
wrinkled up by the sliding upward of the bit, are caught between
the curb-chain and the mouthpiece. The result is that, in the

70 ELEMENTS OF HIPPOLOGY.

_FIGuRE 51.

effort to get away from the pain caused by this pinching, the
horse does not notice the painless pull on the poll,tending to drag
his head down, but does notice the pain to his lips, and throws
his head forward to avoid it. Thus the pinching of the lips
makes the bit a lever of the first class.

When the curb-chain is too tight, so that it slips up out of
the chin-groove to the sharp edges of the branches of the jaw-
bone, the bit is said to stand stiff, as in Figure 51.

ELEMENTS OF HIPPOLOGY. 71

FIGURE 52.

The horse usually opens his mouth when the bit stands stiff
and sticks his nose forward. These actions should at once tell
the rider that the bit is out of adjustment, and he should adjust
it. The correct adjustment is shown in Figure 52. The chain
fits easily into the groove, as the reins are tightened; the lips are
not wrinkled or pinched, but the mouthpiece remains in its place,

so far as to waste the greater part of the exertions of the rider in
a painless pull on the head.
In fitting a horse with a curb bit, there is no better rule to
follow than is used in fitting a man with a shoe—try it on. If
it pinches the lips, it is 400 narrow; if there is play enough to

allow the corners of the port to bear on the bars as the bit slips
from side to side, it is too wide. There should be just room be-
tween the cheekpieces of the bit for the cheek-straps of the
bridle, the curb-chain fastenings, and the horse’s muzzle, with
say a quarter or three-eighths of an inch added to prevent chafing.

74 ELEMENTS OF HIPPOLOGY. -

Before mounting a horse, the rider should always examine
the adjustment of the bit with as much care as he puts in his
inspection of the saddle. Whether or not the horse will be com-
fortable—and if he is not comfortable, the rider will not be—
depends largely on the fit of his equipments, and, more than
any other single thing, on the fit of the bit and curb-chain.

The snaffle bit and the bar bit as well, as we have seen, tend
to make the horse raise his head. The hands of the rider, in
consequence, when using the snaffle, should be held as low as
practicable to counteract this tendency. Figures 53 and 54
illustrate this point. 3

The low position of the hands does not influence the action
of the curb bit, for the depressing action of that bit lies in the
bit itself, and the position of the hands, within limits, has no
effect upon it. The low position is much the more graceful,
however, and, because the hands are nearer to a point of sup-
port, adds to the security of the rider.

The ordinary curb bit exerts a downward pressure on the
poll, which increases as the curb-chain is loosened, allowing the
upper branch to revolve further forward and downward. This
is objectionable, but as no bit has ever been devised that removes
it without introducing more objectionable features, it is a condi-
dition that must be accepted for the present.

The best arrangement for guiding and controlling horses is
the bit and bridoon in common use among good horsemen the
world over. The combination is shown in Figures 50, 51, and 82.
This enables the rider to use the comfortable snaffle or bar bit
for the ordinary business of riding. The curb remains always at
hand, out of the way, simple, powerful, ready to control the
horse in those rare moments, for the well-trained and well-
handled horse, when the snaffle is insufficient.

A Pelham bit is one that combines, in a way, the functions
of bit and bridoon. There are many varieties of Pelham bits,
but the main object of them all is to do away with the second

mouthpiece of the bit and bridoon by attaching the bridoon reins
to rings at the end of the mouthpiece of the bit.

There are thousands of variations of the three classes of bits
described in this chapter.* In all these variations the one ob-
ject sought is to manufacture a bit that will control the horse
and, at the same time, guide him. A horse is an animal of low
intelligence; unless startled or hurt, he is usually willing to do
as he is bid. When suddenly alarmed, his small intelligence is
entirely absorbed in how to escape from the cause of his alarm.
In such a moment his rider must have an instrument that, by
the pain it can inflict, will draw his attention away from the
thing that threatens to the thing that hurts. As a creature of
habit, he has learned to obey certain signals in a set way;.if the
bit, while inflicting pain, also gives the signal he has learned to
obey, he will instinctively obey it. Then the infliction of pain
- should cease.

In selecting a combination of bit and bridoon, the bit should
be powerful, but perfect fitting, and the bridoon as comfortable
as possible, in order to let the horse know definitely the differ-
ence between guidance and control. The guidance should be
mild, the control absolute.

*One firm in New York, dealing in nothing but bits, sends out a

eatalogue of over four hundred pages describing their goods, and
several bits are described on each page,

76 ELEMENTS OF HIPPOLOGY.

BITTING.*

“T have nothing to say about the snaffle, except that it
ought to be rather thick, so as to reduce its severity, and that
it should be placed at about an equal distance from the bit and
the corners of the mouth.

“The form of a curb bit and the position it is placed in the
mouth are points of great importance. It is impossible to de-
cide at first glance what kind of a curb will suit a young horse
best and what position it should occupy in his mouth. Baucher
says that he would use the same kind of a bit for all kinds of
horses, which statement is the consequence of his pet theory that
all horses have the same kind of mouth. Iwill here content
myself with saying that even the most inexperienced horseman
will state that horses go better in one bit than in-another, and
that certain animals will go kindly in a snaffle, but will resent
the use of a rather severe curb. This is a generally accepted
fact, which has been amply proved. We can find the best curb
for a horse only by trial. But there are always certain princi-
ples to help us in making our Peper which we may sum
up as follows:

‘“The curb which is used at the beginning of the breaking
should have a thick mouthpiece, low port, and short cheek-
pieces, so that it may be easy to the mouth. Its width should
be proportionate to that of the mouth of the horse. If it is too
narrow, the lips will be compressed by the cheekpieces; if it is
too wide, the horse, either in play or to relieve the bars of the
mouth from pressure, will bring it too much over on one side
of his mouth, so that a part-of the port will rest on one of
the bars, and consequently the mouthpiece will exert an uneven
pressure, which will almost always cause the horse to carry his
head sideways.

*From ‘Breaking and Riding,’ by James Fillis, pp. 10-13.

ELEMENTS OF HIPPOLOGY. 77

“Tn order that the curb may fit properly, it should be wide
enough for the cheeks to keep clear of the lips on each side. The
mouthpiece should have an even feeling on each side of the
mouth and should be midway between the tushes and the corners
of the lips, and consequently it will be lower in the mouth than
the snaffle, in the case of a double bridle. Later on I shall point
out some exceptions to this rule. The lower ends of the cheek-
pieces, yielding to the pull of the reins, cause the upper ends to
revolve forward, and thus to produce pressure on the bars of
the mouth. The curb-chain, which prevents the upper ends of
the cheeks from revolving forward, increases the pressure on the
bars proportionately to its shortness. Hence, the length of the
curb-chain should be proportionate to the lightness of the horse’s
mouth, which we are unable to estimate in the cese of a per-
fectly green horse. With such an animal, we shculd at first
leave the curb-chain very loose, as there will always bet re to
take it up. It would not, on the contrary, be right to say that
there is always time to slacken a tight curb-chain, which causes
pain that will continue to be felt by the horse after the curb-
chain has been let out. If, however, we begin with a loose curb-
chain and gradually shorten it to the desired extent, we shall
avoid hurting the bars of the mouth and irritating the horse to
resistance, and we gain time. But if, at the beginning of the
work, we hurt or even irritate the bars by undue pressure, we
shall fail to obtain any of the required indications. By arti-
ficially increasing the sensitiveness of the bars, we fail to es-
timate it correctly, and work on a wrong method from the be-
ginning. The bruising or even the mere irritation of the bars
does not disappear as soon as the work is finished and the bridle
taken off, but continues for a more or less long period. Conse-
quently, when the next lesson is given, the bars are congested and
painful. The rider will then be apt to form an opinion of the
effects he produces on the mouth of the horse without taking
into consideration that it is in an abnormal condition, and he will

78 ELEMENTS OF HIPPOLOGY.

increase the evil which has been done, and he will become more
and more unable to correctly estimate what is the natural con-
dition of the mouth. In a word, he will do the very things he
ought not to do. From the foregoing observations we can see
that, at the beginning of the breaking, the curb-chain should be
loose—in fact, it is better to take it off.

‘The knowledge of the mouth of a green horse is an im-
portant and delicate matter. In order to gently feel the mouth
without spoiling it, we must begin with great lightness of hand,
and gradually increase the pressure up to the point of making
the horse feel it, which sensitiveness varies in degree according
to the animal. If a horse yields to the light pressure of a curb
that has no curb-chain, of what use is the curb-chain, and what
is the good of seeking for a more powerful means of restraint?

‘“‘T have thoroughly broken horses, not only forthe mancge,
but also for outdoor work, without using a curb-chain, which
may remain hooked up on one of the curb-hooks, so that it may
be instantly used in case of need. As a rule, it should not be
employed unless the rider finds that- he needs its help. When
he uses it, he should never put more tension on it than is actually
required; the proper maximum being when the curb-chain is
tightened up so that it makes an angle of forty-five degrees
with the lower jaw.

“As the tension of the curb-chain should be proportionate
to the sensitiveness of the bars, so should the pressure caused
by the pull of the reins be proportionate to the resistance. If
this resistance is slight, the effort to overcome it should be light,
and the point of its application should be high up on the jaw; if
the resistance is great, the effort should be energetic and it
should be applied low down. Therefore, without greatly alter-
ing the middle position which the mouthpiece should occupy be-
tween the tushes and the corners of the lips, we may raise or
lower the mouthpiece so that the horse may yield his jaw by,
respectively, a light feeling of the reins or by a strong pull on

ELEMENTS OF HIPPOLOGY. 79

them. In other words, the softer the mouth is, the higher should
be the mouthpiece; and the harder, the lower should it be placed.
In no case, however, should it press on or even touch the corners
of the lips or the tushes.

‘We learn from the foregoing remarks that the proper ten-
sion of the curb-chain and the right position of the mouthpiece
in the mouth of the young horse can be found only from ex-
perience, which should be gained from very slight effects tha4
can be gradually increased in severity as the case may demand.”

CHAPTER: VI.

THE FRONT LEG.

Beginning at the top, the bones of the front leg are named
as follows: shoulder- blade ieee pula), arm-bone (humerus),

forearm-bone* (radius), the
bones of the knee, cannon-

two, one each side of the
cannon-bone (A, Figure 59),
the sesamoids, upper and
lower pastern-bones, navic-
ular-bone, and _ coffin-bone
(Figure 56).

The joints are the shoul-
der-joint, the elbow-joint,
the knee, the fetlock-joint,
the lower pastern-joint, and
the navicular-joint.

The external nomencla-
ture of this region is shown
in Figure 57.

The shoulder-blade, which
has no bony connection—no

articulation—with the trunk, is bound to it by muscles alone.

The horse has no collar-bone.

Below, it articulates with the

arm-bone at the shoulder-joint. Unlike the other joints in the
horse’s anatomy, these two bones are not bound together by
numerous ligaments, but by one very strong enveloping ligament,

which permits great freedom of extension and flexion, and some
side-play. It is a very strong joint, and is not lable to sprain,
except from external causes. In almost every case of obscure

ALEMENTS OF HIPPuUnwGY. 83

lameness in front, the trouble lies below the shoulder-joint. The
point of the shoulder marks the position of the shoulder-joint.
The shoulder-blade should slope well forward, towards the point
of the shoulder, in order to insure a comfortable seat: for the rider.
The arm-bone articulates with the forearm-bone at the elbow-
joint. This joint is a little below the upper end of the leg-bone,
and the projection of the bone, above the joint, is called the
elbow. In order that the horse shall be ‘‘handy’’ in front, or
have a free action, the elbow should have considerable lateral
motion. The absence of this condition is termed tied down
to the chest.

Sprains in the elbow-joint are very rare. All bones are
covered with membranes that secrete either bony tissue or fluids
needful to keep the bones properly moist. At the elbow and
hock, these membranes are not covered by muscles, but directly
by the skin. Inflammation, resulting from a blow to these un-
protected parts, is not manifested in the usual way, but by an
increased seqretion of fluid, accompanied by a thickening of the
skin and membranes over the injured part. This fluid is the
same that is found in the familiar water-blister. When the elbow
‘is injured, the resulting ‘‘blister’’ is termed a capped elbow
(Figure 58). This trouble is found most frequently in horses
carelessly or ignorantly shod, and stabled on brick, concrete, or
granite block floors, and is due to the shoe, or the floor, striking
the elbow when the horse lies down. It is sometimes called a
shoe-boil, and, while easily removed, if taken in time;s till its
presence argues some weakness in the foreleg that prevents the
horse from easing down properly in the act of lying down; he
brings his elbow to the ground with more force than a sie
sound horse of good conformation should do.

Between the leg-bone and the cannon-bone is a group of
small bones, six in front, called carpals, and one, larger, in rear,
called the trapezium (Figure 59). The joint formed by these
bones is called the knee. It is a hinge in the continuity of leg-

bone and cannon-bone, whose function is to enable ‘the foot to
be brought forward without striking the toe on the ground, and,
by the elasticity of its cartilages, to reduce the shock of impact
of the foot with the ground. :

The trapezium
is a bone placed
at the back of
the knee to af-
ford a lever-like
attachment for
the tendons that
bend the knee.

wards the foot.

FIGURE 58.—CaprEep ELBow.

The other two, on either side of the cannon-

bone, are rudimentary, and are called splint bones (Figure 59 A).

ELEMENTS OF HIPPOLOGY. 85

When viewed from the front or side, the knee should be
broad; wedge-shaped, when viewed from the rear.

The leg below the knee
should not become rapid
ly smaller, but should ta-
per gradually towards
the upper pastern-joint.
When it is decidedly
smaller just below the
knee, the horse is said
to be tied in below the
knee.

Horses that are knee-
tied usually owe that de-
fect to a small trapezium.
This makes them defici-
ent in power where it is
very necessary.

86 ELEMENTS OF HIPPOLOGY.

a horse is sure on his front feet. Broken knees are a sign of a
failure at some time in his history; hence a most careful scrutiny
of the front faces of his knees should be made.

It often happens that a horse falls and bruises his knee in a
perfectly innocent way, but such happenings are rare. As a
rule, the fall is due
to some defect in
the horse himself.
The would-be pur-
chaser is wise who
rejects finally any
horse with broken
knees.

The back tend-
ons, leading from
the trapezium to
the pastern, when
strained, are causes
of lameness. ‘This
strain occurs more
often in saddle
horses that are gal-
loped when tired.
It is noticeable by
an enlargement of
the tendon, or its
sheath, below the
knee, usually nearer
the knee than the |
pastern, and a tendency to keep the knees bent forward when
at rest, to ease the strain on those tendons.

A tendon is a dense, fibrous tissue that connects a muscle
with a bone. Its function is to transmit the energy developed
by the contraction of the muscle to the bone.

- FIGURE 60.—BROKEN KNEES.

ELEMENTS OF HIPPOLOGY. 87

A ligament is also a dense, fibrous tissue, and serves to bind
two bones, usually, together. Tendons are usually of the shape
of ropes, and do their work, while ligaments are of a variety of
shapes. The ligament that binds the shoulder-blade to the arm-
bone, at the shoulder-joint is like a broad, enveloping bandage.
The ligaments joining the head and withers of a horse and sup-
porting the vertebre of the neck resemble closely the cable and
supporting rods of a suspension-bridge. The bones of the knee.
and the hock are held in place by numerous ligaments of a variety
of shapes, while the ligament that supports the contents of the
abdomen, hung between the ribs, the hips, and the under side of
the pelvis, is shaped like a hammock.

A cartilage is a dense, highly elastic substance that envelops
the ends of bones at joints.

There is no room for muscles between the knee, or the hock,
and the ground. The space between the skin and the bones is
filled with tendons, reaching from the muscles of the shoulder
and arm to their attachments on the cannon-bone, pastern, and
foot, with ligaments binding the bones together, the sheaths of
these tendons and ligaments and the nerves, blood and other
vessels supplying the lower leg and foot. All these tissues are
compact, lying closely together. They should be cool to the
touch, smooth and firm. Any puffiness, any undue heat, any
sensitiveness or roughness are sure signs of disease.

Often when a horse is idle and is over-fed, his legs will swell
and will become feverish and painful. The animal will move in
a stilty, stiff way. This lameness will disappear with proper
feeding and exercise, and it should not be confused with the
‘lameness resulting from ligaments or tendons strained from
overwork.

In the young horse the three metacarpals are separateb ones.
Due to injury, or conformation, or improper shoeing, or over-
work, these bones throw out bony deposits that graduallyu nite
them. _ In the aged horse this union is a normal condition, and,

88 ELEMENTS OF HIPPOLOGY.

if the bony tumor marking the union is not so high as to inter-
fere with the action of the carpals, or far enough back to inter-
fere with the action of the tendons and the suspensory ligaments,
no harm results. This is the simple splint (Figure 61).

A beaded splint isa series of two or more such enlargements,
running down the splint-bone.

If the bony deposit spreads to the back of the cannon-bone
and across it to the splint-bone on the other side, it is called a
pegged splint. This is its worst form, is incurable, and results
in chronic lameness.

If the bony growth encroaches upon the carpals, or inter-
feres with the tendons or ligaments, serious lameness, usually
incurable, results.

In Figure 59 the position of the splint-bone, A, with respect
to the knee-bones, the tendons in rear, and the cannon-bone,
B, is clearly shown. The tendons, when the horse is in motion,
are in constant motion up and down. They are immensely
strong, inelastic tissues, covered with delicate membranes that
supply the lubricants necessary to permit them to slip easily
and freely. 3

Any bony growth on the rear of the splint-bonew ill inter-
fere with this ease of movement, and the roughness of the bony
tumors will lacerate and inflame the sheaths of the tendons. _

If the bony tumor encroaches on the knee-bones, it is seen
easily that much damage will result.

If, however, the union between the bones A and Bis effected
by a growth between the bones and to the front, there is no
moving tissue that is interfered with,and lameness will not result.

The extremely large splint shown in Figure 61 has appar-
ently not inconvenienced the horse in the least.

A wound on the upper end of the inside splint at A, Figure
59, caused by the shoe of the other front foot striking it at high
gaits, is called speedy cut. ‘This is a veryserious defect. The
interference that causes it happens only at high speed; the pain

ELEMENTS OF HIPPOLOGY. 89

resulting is very great, sufficient often to bring the animal to his
knees, and to cause deplorable accidents.

The line of the foreleg should be nearly straight, the cannon-
bone prolonging the radius. If this line bends forward, the
horse stands over
at the knees; if it
bends back, he is
calf-kneed. The
former is a sign of

ELEMENTS OF HAIPPOLOGY. 93

The principal function of the foreleg is to support weight,
to carry the forehand and its load ahead and out of the way of
the propelling haunches. It must be so shaped that it can per-
form this work without injury to itself and carry its load as
nearly level as possible.

Elasticity in carrying its load is secured through the car-
tilages and muscles. The shock of impact is transmitted at each
joint, partly to the bone above the joint and partly to the
muscles controlling the bone below it, through the tendons con-
necting them. The smaller the angle between two adjoining
bones, the greater will be the portion of the shock transmitted
to the muscles. In the foreleg, three joints are between bones
inclining more or less to each other—the fetlock-joint, the elbow,
and the shoulder-joint. If the upper pastern-bone is long, it
will slope well from the cannon to the hoof; if it is short, it will
stand straight. Similarly, a short arm-bone will bring the point
of the shoulder nearer the elbow and straighten the shoulder-
blade.

The foreleg of the camel is straight from the foot to the
upper end of the shoulder-blade. Consequently, the shock of
impact is carried to the shoulder muscles, lessened only by the
elasticity of the cartilages between the bones. As a result, the
camel is the most uncomfortable saddle-animal known.

The slope of the shoulder should be about forty-five degrees
and that of the pastern about the same. The horse shown in the
half-tone on the following page may be taken as a model of con-
formation. His shoulder-blade slopes at the proper angle, and
is very long. His forearm is very long, .jand strongly muscled.
His elbow, knee, and pastern are smooth, clean-cut joints. The
cannon is short and prolongs the forearm.

A straight shoulder and a straight, short pastern should be
avoided. The horse will not only be uncomfortable to ride, but
he will ‘‘pound’’ himself at the faster gaits and become lame from
¢he concussion.

Splints, sprained tendons and ligaments, ringbones, side-

this concussion.

CHAPTER VII.

r THE BACK.

The back is mainly of interest because it furnishes the posi-
tion of the saddle, and it is necessary to know something oi its
anatomy to be able to place the saddle and its lead so they will
not injure it.

The bones of the back are eighteen vertebre of the spinal
column, and the nbs. The first eight of these vertebre, with
their muscular coverings. are called, taken collectively, the
‘withers The upper spines of six or seven, usually, of these
bones are much longer, as can be seen in Figure 67, than on any
of the others, and they furnish points of attachment for the sus-
pensory ligament of the neck and for several important muscles
of the back, shoulder, and mbs.

In front of the haunch-bone are six vertebre, called the
lumbar vertebr2; they slope towards the front. All the verte-
bre of the back are well padded with muscles on the sides, but
are very close to the skin on top, and these upper extremities
must be very carefully protected from any pressure.

Looking at Figure 66, the muscles of the back are seen to be
broad and long. These muscles have slight mofions; they are
several inches thick, and are admirably adapted to receive the
saddle and its lead, provided the load is kept off the spinal
column and is evenly distributed.

Qn each side of the withers, a little lower than their crest,
lie the upper ends of the shoulder-blades. These bones are
tipped with a broad, thick band of cartilage—indicated in Figure
67—to protect the bone itself from injury.

The shoulder-blade, as has been said, has no bony union
with the spinal column. It is simply bound on the ribs and
spinal column by a number of very strong muscles that control
its movements. The center of its motion is about one-third its
- length from the upper end. When the foot is brought forward,
the lower end of the shoulder-blade swings forward and upward,
around this center of motion, and the upper end swings back-
ward and downward.

The saddle must be so plac@@ as not to interfere with the
free play of this bone. It has been found that if the front of the
side-bar of the McClellan saddle is placed so that three fingers
can be laid between it and the shoulder-blade when the horse is
standing, the play of the bone will not be interfered with.

The saddle in ordinary use for pleasure-riding does not need
to be built to carry any load but the rider. It has a very small,
rigid frame, called the tree, is carefully and thoroughly pad-
ded, and needs no blanket or pad under it to protect the horse’s
back. A leather sweat-pad, called the numnah, should be used
under it to protect its padding from becoming ruined by sweat,

These saddles should be padded to fit each particular horse.
and should not be used on another horse. If this precaution is
taken, the saddle will naturally fall on its proper place and will
stay there. As long as the padding is good and the numnah
kept clean, there is small danger of injury being done to the
horse’s back.

The McClellan saddle, however, must often be changed from
one horse to another. Its tree is larger and its bearing surface
considerable to provide points of attachment for the packs that,
from time to time, must be fastened to the pommel and cantle.
The horse’s back is protected by a folded woolen blanket.

This blanket must be folded very carefully; no wrinkles
should be allowed, nor any dirt or other foreign substances, in any
of its folds. Anything that causes undue pressure on any spot
under the saddle will compress the capillaries of that spot and

tL. OF G,

prevent it from receiving the supply of blood necessary to keep
it built up. If this pressure is sufficient to chafe the skin, the
resulting wound is very liable to become infected, as the woolen
blanket, impregnated with sweat, is a favorable place for the
growth of microbes. If the skin is not broken, when the pressure
is removed the spot affected will immediately become inflamed,
and a sore will probably result, under the skin, that will, unless
taken properly in hand, finally destroy the skin over it, and be-
come an open sore. In either ease the horse is said to have, first,
a saddle-gall; then, if this is neglected, it becomes a sore back.
If this sore back is along the ridge of the back-bone, the pus
cannot easily be drained; it may make sinuses along the spines
of the vertebre, and a fistula results.

Another serious result of a neglected sore back comes when
the sore practically heals. Active suppuration has then ceased,
and the wound heals over imperfectly, leaving a dead, hard
piece of skin over the sore, itself covered by a thick scab. An
inert abscess is left under the skin, which breaks out when pressure
is again applied to it. This is a sitfast, an obstinate, trouble-
some sore, that needs constant watching.

If there is time to devote to it, the sitfast should be cut out
and the wound compelled to heal slowly, -filling up from the
bottom with sound tissue.

When the saddle is first removed, the horse’s back should
be carefully looked over. If any chafed places or inflamed spots
are noticed they should be washed clean and briskly rubbed for
fifteen or twenty minutes to restore a healthy circulation. Fo-
menting the back with warm water, carefully drying it before
leaving it, is also an excellent treatment. The under side of the
blanket should be inspected, to locate the cause of the trouble,
and the greatest. care should be taken, when the horse is next
saddled, to keep all pressure from the sore spot. This can be
affected by cutting a hole in the blanket over the sore, saddling
carefully, and adjusting the blanket at every halt.

ELEMENTS OF HIPPOLOGY. 101

A saddle-horse should have a flat back, moderately high
withers, not too thick, and a sloping shoulder. Figure 65 shows
an excellent back. The shoulder is especially good. A long,
sloping shoulder, reaching out well in front of the rider, gives
him a feeling of security that he cannot have if the shoulder
ends near his own knee.

The muscles that pull the shoulder-blade forward are at-
tached to the poll and upper four neck vertebre; the ones that
draw it back are attached to the dorsal and lumbar vertebree
and the first eight ribs. This explains why a horse that is down
can be kept down by raising his head and bending it back to-
wards his shoulder. The neck muscles that move the shoulder-
blade forward—and hence the whole leg—are incapable of acting.
If a horse cannot move his foreleg forward when he is down, to
get a bearing, he cannot rise.

High withers, extending well back, are generally associated
with long necks, long and sloping shoulder-blades, and powerful
back muscles. Low withers are generally found on animals
with short necks and straight shoulder-blades. The withers
should not be too fleshy and thick.

The two horses shown in Figures 69 and 70 have each very
prominent withers. The one in Figure 69 has very thin withers,
and his back slopes too much from the croup. The result is that
the saddle could not be kept from chafing the top of his withers,
which were always sore after a ride. He was, in consequence,
not for duty most of the time, and had to be sold as unfit for
saddle purposes.

While he was a coarse, ill-looking animal, still he was very
strong, active, and comfortable to ride, and, aside from his sore
withers, perfectly sound when sold. But for that defect he
would have given many years of useful service.

The horse shown in Figure 70 is a useful specimen of what is
termed the general-purpose horse; he is equally good to ride or
to drive. He has a strong strain of the American saddle-horse

with a thoroughbred cross. He is a fine saddler, drives well,
single or double, is not dainty with his food, and thrives well in
the field. He has been ridden by an officer for ten years, and is
as good as ever.

His withers are as high as those of the horse in Figure 69,
but not so thin, and his barrel is longer and more cylindrical.
The saddle, if placed off the withers on saddling, will stay there
with very little watching. He is not shown as a perfect model,
but as an example of an extremely useful individual, in spite of
what might seem serious defects in conformation.

104 ELEMENTS OF HIPPOLOGY.

Figure 71.—NBARLY EVERYTHING WRONG.

The horse shown in Figure 71 has been several years at the —
Military Academy. His withers are much too thin and prom-
inent, but are kept from ever getting sore, because it is Impos-
sible to keep the saddle in its position long enough to chafe them,
unless intentionally fastened there with a too tight breast-strap;
even then his shoulder is so straight that it has but little play.
He is rough to ride, ungainly, and has no staying power. He
can hardly be said to have a single redeeming trait.

THE TRUNK.

If the legs and neck were removed from the horse’s body, ihe
trunk would remain. It is subdivided into the breast, the chest
with its enclosing ribs, the back and loins, the abdomen—the
cavity in the rear part of the trunk—and its contents, the hips,
and the croup.

The breast is the muscular front portion of the chest, and is
bounded by a line connecting the points of both shoulders and
by the arm-bone on each side. For saddle purposes, great width
of breast is usually at the expense of leaping power and speed,
since this width is usually produced by over-development of the
shoulder muscles, and not because of increased capacity of
the chest.’ :

The lungs and heart are enclosed, by the ribs and dia-
phragm, in the chest. It is by the expansion of the chest that
air is brought into the lungs, and by its contraction that air is
expelled. This expansion and contraction is performed by the
muscles of the ribs. The greater the expansive power of the
chest, the greater quantity of air will be drawn into the lungs,
and the purifying and vitalizing of the blood will be more com-
pletely performed. The ribs should, therefore, be long, convex,
and slope to the rear. A horse whose ribs approach close to
the haunch-bone is said to be well ribbed up.

The cavity of the chest is separated from the abdomen bya
muscular partition, called the diaphragm. The entire cavity
of the chest is lined by a very smooth, well-lubricated membrane,
called the pleura, which envelopes, without attaching itself to,
the heart and lungs. The abdomen contains the stomach, the

HLEMENTS OF HIPPOLOGY. hGZ

intestines, the kidneys, and the various glands whose secretions
assist in the processes of digestion.

It is by the expansion and contraction of the chest that the
lungs perform their function of purifying and oxidizing the blood.
The lungs cannot be too big. The chest, to contain large lungs,
should be deep, from top to bottom, long from front to rear,
and have great convexity.

The abdomen must also be roomy, but only to a certain
extent. If the abdomen is small—‘‘tucked up,”’ as it is called—
there will be little room for food to be stored, the horse will be a
dainty eater, requiring frequent feeding, and he will be unfit
for hardservice. If his abdomen is too large, its excessive weight
will prevent the horse from being active or fast, and he will be
clumsy and unpleasant to ride. A horse possessing the first
fault is said to be herring-gutted, and the last mentioned,
pot-bellied.

The saddle on the pot-bellied horse is constantly slipping
forward to bruise the withers or the shoulders. On the herring-
gutted horse it keeps sliding back, to the annoyance of the rider.

The contents of the abdomen are held in place by the ab-
dominal tunic, a very powerful ligament, and by other tendons
and muscles. This abdominal envelope should continue the
lines of the ribs. The profile of the belly should slope gently
downward from the sheath to the girth-place.

The loins include the six lumbar vertebre and their mus-
cular covering. The region of the loins is commonly known as
the coupling.

If the ribs slope to the rear well, and the loin muscles are
thick and strong, the horse is well coupled. For saddle-horses,
the coupling should be short and the muscles strong and thick.

The curve of the profile of the horse’s back—from withers
to tail—should be, when viewed from the side, smooth and flat-
tened (Figure 70). There should be no ‘‘jog’’ (Figure 71) in
front of the haunch-bone in horses in good condition. Most

108 ELEMENTS OF HIPPOLOGY.

horses in low condition show a slight interruption in the curve
of the back at this point, due to the wasting away of the muscles
filling in the angle between the last vertebra of the loins and the
first of those of the croup.

The hips should be well rounded and not too prominent. A
horse with too prominent, ragged hips is apt to strike and break
them when going through narrow gates or doorways. When
the point of the hip is broken, it is easily seen by the lack of
symmetry, when viewed from the rear. The usefulness of the
animal is not always impaired by such an accident, nor is he
always made, even temporarily, lame by it.

The diaphragm is the muscle that controls inspiration—
the act of taking air into the lungs. When the air enters the
lungs, the diaphragm is pressed against the contents of the ab-
domen, they in turn press against the abdominal tunic, and it,
being fastened to the point of the hip, exerts a pull there at each
breath. A broken hip, therefore, cannot rest long enough to
heal properly, and the symmetry of the part is always marred. _

The region between the hips, the loins, and the posterior
ribs is called the flank (Figure 67). This should be well filled
out and not too large. In the horse that is well ribbed up, there
should be no more than room enough to lay the hand between
the ribs and hip. A gauntness appears in the flank after great
exertion, or when feeding or watering has been neglected. A
horse that is losing condition shows it first in the flank.

The croup should slope downward toward the tail but little
and should be convex in profile, viewed either from the side or
rear. Horses whose croups slope too much towards the rear
are termed goose-rumped (Figure 68). Aside from being un-
sightly, a goose-rumped horse lacks muscular development where
it is very necessary, since certain of the large muscles of the
thigh form their attachment there. These muscles originate
propulsion, and any lack of development or loss of leverage
reacts directly on the strength and length of the animal’s stride.
The five vertebre of the croup grow together early in the life
of the horse.

The dock is the tail, without its hair.

ereat strength and mass, and its position and movements are
entirely obscured by them. The thighs should be well filled up,
viewed from behind, leaving no open space between the legs.
‘The stifles should be slightly wider apart than the hips, to insure
freedom of movement in the stride.

The stifle, or patella, corresponds to the human knee-cap.
Its function is to afford additional leverage to certain muscles
that advance the leg. It lies in front of the stifle-joint, and is
held in place by several ligaments. Dislocations of the patella
are rare, but are much more frequent than dislocations of any
other joint. A horse suffering from this dislocation is said to
be stifled.

The leg-bone, or tibia, lies between the stifle-joint and the
hock. The lower part of the muscles of the tibia is termed the
gaskin, and it is important for fast work that these muscles be
well developed. The muscles of the thigh start the propulsion;
it is accelerated by the upper muscles of the tibia and the muscles
of the gaskin give the final impulse to the stride. They are
smaller and shorter than the upper muscles of the hind leg and
their action correspondingly quicker. It is therefore important
that their development be considerable.

Aside from the rare dislocations of the patella, and fract-
ure of the points of the hips, there are no common injuries
to be looked for in the region of the hind leg, above the hock.
This joint, however, is very liable to be disabled by an obscure
disease, often difficult to discover, and always, when existing,
of a nature that makes the animal permanently unsound. This
disease is bone spavin.

The hock is a more complicated joint than the knee. It
is composed of six bones, five of which are interposed between
the tibia and the cannon-bone, and a sixth placed behind them
to act as a lever for certain of the tendons of the leg. In Figure
77 the cannon-bone is the bone at the bottom of each drawing.

The tibia, leg-bone, is entirely removed. It articulates with the

HLEMENTS OF HIPPOLOGY. 115

upper front bone that is so deeply grooved in the cuts. The bone
near the numbers (1, 2, 3, and 4), standing back of the others, is
the sixth bone referred to, and is the bone that forms the promi-
_ hence in rear of the hock. The true hock-joint is between the
upper bone of the five and the leg-bone; most of the motion of
the hock is about this joint, and it is seldom diseased. The
other four bones have smaller motions among themselves, but
their principal function is to lessen, by the elasticity of their
cartilages, the shock of impact.

The properly shaped hock is clean in its outline, with its
angularities well defined. The point of the hock should be
prominent, and the depressions in front of it should be pro-
nounced; there must be no puffiness about this joint.

The bones are covered with membranes that secrete fluids
necessary for their building up and preservation. The carti-
lages between the bones possess most of the chemical elements
of the bones themselves, except the lime and other salts that
give the bones their rigidity and strength. When the mem-
branes or cartilages are injured through any cause, inflamma-
tion sets in, and the functions of secretion are stimulated. As
a consequence, more of the bone salts are secreted than are
needed for the maintenance of the bones, and the excess is de-
posited on the outside, in the form of rough nodules that invade
the spaces needed for the proper working of the ligaments and
tendons of the joint, or in the tissues of the cartilages, which
thereby loose their elasticity and become bone. This deposit
may go on until the joint is destroyed by the excess bony de-
posit cementing the bones together.

In the hock-joint there is a great change in the direction of
the energy developed in the propelling muscles, and everything
connected with the joints should work smoothly to get the best
results. Any strain due to excessive concussion is apt to set up
inflammation between the lowest bones of the hock and the
head of the cannon-bone. This inflammation, if not stopped

116 ELEMENTS OF HIPPOLOGY. -

before the bony deposit begins, results in bone spavin. Its usual
seat is shown opposite the upper turn of the letter S in the
word “‘seat,’’ Figure 78.

The usual treatment of a spavin, after the bony deposit
has fairly begun, is to stimulate the deposit by artificial inflam-
mation until

to stand for thirty minutes, and then sharply galloped, he will,

if spavined, go noticeably lame. This is a characteristic of
the disease. }

If the existence of spavin is suspected, another test is to
pick up the foot and bend the hock well, holding the foot up for
a minute or so. If the horse travels sound immediately after,
he may be assumed to be sound.

Between most of the joints of animals are placed closed
membranous sacs, called synovial burse, filled with a clear,
yellowish fluid, called synovial fluid, or joint oil. Thesesacs
are to diminish
friction in the
joints. Enlarge-
ments of these

largements,

are, unless very

Blood-spavin is an enlargement of a large vein running up
the leg. It is usually caused by the pressure of a bog-spavin
damming the flow of the blood in the vein (Figure 79).

Capped hock, like capped elbow, is, in its first stage, a
blister (Figure 80). Its seat is the point of the hock. It is,
when first formed, easily removed, causes no lameness, but
points to bad stable habits, and is unsightly. |

A curb is a protuberance on the back of the hind leg, six
inches or so below the point of the hock. It is caused by ‘‘a
sprain of the tendon, which passes on the posterior of the hock,
or of one of its sheaths, or of the strong ligament situated on
the posterior border of the upper bone of the hock.’’*

It is shown by a bulging backwards of the posterior part of
the hock, interrupting what should be a straight line between .
the point of the hock and the fetlock.

The inflammation in a curb, when it first appears, should
be subdued by cold applications, and the further treatment of
it left to a veterinarian.

Curb is an unsoundness, and a permanent disfigurement.
Its commonest cause is making a horse stop suddenly when at
a rapid gait, thus throwing an excessive strain on the back
ligaments of the hock.

Lymphangitis is a disease of the lymph-ducts (small ves-
sels carrying nourishment to the tissues), near the skin. It is
manifested by an unsightly, permanent thickening of the skin.
It is not, in its first steps, disabling, but is a serious blemish.

Splints occur sometimes in the hind leg, but less often than
in front. The pasterns of the hind leg slope less than those in
front. They are more liable to ringbones than the front ones.
Sidebones are very rare in the hind foot.

120 ELEMENTS OF HIPPOLOGY.

Stringhalt is an involuntary jerking up of the hind leg
(usually), bending the diseased member more than the sound
one. It presents many phases, sometimes showing at the walk
only, sometimes at the trot only, sometimes at all gaits. Its
cause is unknown. It is very unsightly, is incurable, and usually
increases with age. 3

In conformation the hind leg should be powerful, without
being clumsy. ‘The croup should be concave, viewed from side
or rear, and the hips not prominent. The tail should be carried
away from the buttocks, and should not prolong the curve of
the croup. It is noteworthy that a horse possessing courage
and mettle always carries his tail well up until utterly exhausted.
When his tail drops, while he is in motion, it is a warning to
rest him.

Viewed from the rear, there should be a slight concavity
between the hips and the stifle, and the stifles should be slightly
wider apart than the hips. If the hips are wider than the stifles,
and prominent, they are said to be ragged. From the stifle to
the hocks, the legs should converge, and the curve of the gaskin
should be clean-cut and pronounced (Figure 75). The tibia should
be—or should appear to be—very long, and the hocks low, to.
get great power. ‘The upper bone of the hock—the os calcis—
should be pronounced.

For saddle-horses, the hind legs should be ‘‘under the
croup’’—that is, a line dropped from the point of the croup
should pass along the cannon, from hock to fetlock, or near it.
The legs, from the hock to the ground, should be parallel and
straight. If the hocks are nearer together than the fetlocks,
the horse is cow-hocked if the hocks are wider apart than
the fetlocks, he is said to be open behind. When the cannon
slopes to the front from hock to pastern, the horse is sickle-
hocked. All of these conditions are objectionable.

The hind legs are less liable to injury than the front ones
in saddle-horses not trained to Jump, in cavalry-horses, and .in
polo-ponies, while in hunters and in harness-horses the hocks
are the most vulnerable places.

CE AP TER

THE HORSE’S FOOT.

The foot of the horse, from a standpoint of comparative
anatomy, includes everything below the knee or hock. Prac-
tically, horsemen, in speaking of the horse’s foot, refer ue to ime
hoof and its contents. The [| = = #@9 7
hoof corresponds in its
structure to the nail on the
toes of other animals.

The foot is one of the most
important parts of the
horse to study, because it is
the seat of so many dis-
abling diseases, practically
all of which can be prevented
by proper care and use.

The foot is a very com-
plex member. It is built
around three bones: the |
coffin-bone, the navicu- |
lar bone, and the lower

pastern-bone.

The co ffin-bone, the low-
est bone of all, hes wholly
within the hoof. It is wedge-
shaped, concave on its under surface, and cylindrical on the up-
per sides of its anterior and lateral faces. In rear it branches
into two parts, called the wings of the coffin-bone. ;

Immediately above the coffin-bone, and resting on its highest
part, rises the lower pastern- or coronary-bone; and in the

IGURE 81. —NOMENCLATURE OF

angle behind the joint, formed by the coffin- and lower pastern-
bone, fits the navicular-bone. ‘These three bones are bound
together by several short, strong ligaments. Two wide and
thick pieces of cartilage, continuing the wings of the coffin-bone,
called the lateral cartilages of the coffin-bone, fit in behind
the three
bones, be-

and the

pulling back—tendon of the leg. Another broad tendon is fas-
tened to the front of the coffin-bone to pull it forward. This is
an extensor tendon. Both are well shown in Figure 82.

Under the flexor tendon and the lateral cartilages is placed
a soft, highly elastic cushion, called the plantar cushion, that,
by its compression between the sole and frog of the hoof on its
under side and the tendon and lateral cartilages above it, acts
to soften the shock of impact.

Enveloping all the structures above enumerated is the fleshy
continuation of the skin, much changed in appearance from that
above the hoof. This covering is highly vascular—that is, it is
abundantly supplied with nerves and with blood and other ves-
sels that supply the foot. The upper border of this covering is
called the coronary band, and along the upper border of this
band is another band, called the perioplic ring. Below the
coronary band the fleshy covering of the foot is covered with a
series of little ridges, called the sensitive lamine. They fit
into corresponding depressions in the inner surface of the wall.
These depressions in the wall are called the insensitive lamine.

On the plantar surface, the fleshy envelope is called the
velvety tissue.

The hoof is the nail of the horse. It is composed of three
parts—the wall, the sole, and the frog. The wall includes all
that portion of the horny box that is visible when the foot is on
the ground. ‘The wall is divided into three regions: the toe, in
front; the quarters, on the sides; and the heels, in rear. At the
heels the wall doubles back, towards the center of the foot,
forming the bars. The wall is thickest at the toe and is grad-
ually thinner towards the heels, where it thickens again to form
the bars. The outer face of the wall is composed of a great
number of filaments, similar to hair in their growth and compo-
sition, compacted firmly together with a natural glue, and grow-
ing downward from the coronary band. It is covered with a sort
of natural varnish that is secreted by the perioplic ring. The

ELEMENTS OF HIPPOLOGY. 125

function of this varnish is to retain the moisture of the horn,
which shrinks on drying and is liable to crack. ‘The interior face
of the wall is composed of the insensitive lamine.

The fore foot is rounder, more spread out, less concave, and
a little wider than the hind foot. Its heels are closer together,
and the angle of its wall is usually more oblique than the hind foot.

The hoof-wall grows downward from the coronary band.
The new growth is always at the top, pushing the old growth
downward. This old growth must be removed, either by natural
wear, in the unshod horse, or by the blacksmith when the horse
is shod. The sole and frog grow in the direction of their
own thickness, and surplus growth scales off, unassisted.

126 ELEMENTS OF HIPPOLOGY.

It requires about eight months to grow a new hoof. This
growth of wall is faster at the toe than at the heel, and in the
unshod horse the wear is greater at the toe, consequently the
wall is maintained at the proper height.

The hoof grows faster during a moist, warm season, if the
animal is in good health, than it does in dry or cold weather, or
when the horse is debilitated. The hoof often shows the effect
of the more favorable season by a thickened ring in the horn.
Such rings, when of healthy growth, are called grass rings.

When the foot strikes the ground the tendency is to force
the coffin-bone down into its wedge-shaped seat. This is pre-
vented by the intimate union between the sensitive and in-
sensitive laminze (whose folds, if spread to their complete de-
velopment, would cover more than a square yard), and by the
elastic resistance of the frog, the plantar cushion, the flexor
tendon, and the lateral cartilages.

The sensitive and insensitive lamine not only dovetail into
each other in the direction of their length, but they are also
provided with multiple barbs that also interlock and resist any
sliding tendency. All these elastic media unite in receiving the
shock of impact and transmit it gradually through the bones
and tendons of the legs and to the muscles above for its final
decomposition.

The foot itself actually spreads out slightly, and the con-
cavity of the sole is reduced at the moment of impact. For this
reason, except when necessary to prevent the undue spreading
of the heels while the horse is in motion, shoes should be left
open at the heels.

The plantar surface of the foot is shown in Figure 85, after
it has been levelled off to receive the shoe. The frog and its.
cleft are clearly seen. The doubling back of the wall to form
the bars shows plainly at the heels. The line of demarcation
between the sole and wall is shown in the dark line paralleling

the wall at the toe. The position of this line also shows the
thickness of the sole.

A saddle-horse should not have too large a foot. A large
foot is characteristic of a slow, lymphatic animal. Its horn is
usually less dense than in a smaller foot on a horse of the same
size. Such a horse is more liable to diseases of the feet when

Figure 84.—TuHeE Hoor.

the horse is called on to do fast work. Large feet belong properly
to draft-horses.

The foot should not be too small, for its smallness will
usually be at the expense of thickness of wall.

The feet should be of the same size, allowing for the differ-
ence in shape in fore and hind feet, and the angle of the wall at
the toe should be about forty-five degrees, getting gradually
more nearly vertical as it approaches the heels. —

If the angle at the toe is much less than forty-five degrees,
the horse is said to be flat-footed. This is usually accompanied

by a flat sole and a predisposition to disease.

128 ELEMENTS OF HIPPOLOGY.

A horse that toes-in is said to be pigeon-toed, and out-
bowed if he toes out. If one foot points to the right or left,
while the other one is straight, he is club-footed.

A vertical plane, paralleling the axis of the horse, and cut-
ting the foot at the toe, should split the foot in half, and contain
the axis of the leg. In other words, the forearm and cannon
should be straight and vertical, and the foot should be set squarely
to the front on the same vertical axis. The outer lines of the
two forearms usually converge towards the knee, due to mus-
cular development. The column of bones should be straight.

DISEASES OF THE FOOT.

As we have seen, there is seldom reason, to suspect disease

quite often, and the
pasterns and feet
are especially liable
to be the seats of
disease. Inthe
feet, no part is
exempt.

Beginning at the
plantar surface, we
find a very common
disease in inflam-
mation of the frog,
called, commonly,
thrush.

Thrush isa dis-
ease of filth and
neglect. The salts
of urine have an es-
pecially bad influ-
ence on horses’
feet, and those

animals that are allowed to stand in mud-puddles made of the
clay of their stalls mixed with urine are very apt to have this
‘disease. It also comes from subjecting the animals to extremes

a ee

130 ELEMENTS OF HIPPOLOGY.

of dryness and moisture, from hard work on rough, stony ground,
or from being continually working or standing in mud.

The disease first shows itself by a constant moisture and
foul odor in the cleft of the frog. If neglected, a thin watery
discharge follows, changing into a thick, very offensive discharge;
in this stage the frog becomes rapidly destroyed.

The treatment is cleanliness and the removal of the exciting
cause. This will usually be sufficient in the first stages. In the
late progress of the disease it resists treatment stubbornly, and
needs most careful attention. In the absence of a veterinarian,
the foot should be thoroughly cleaned, the’ ragged parts of the
frog cut.away. The diseased parts should then be dusted with
calomel or iodoform, and the cleft packed with oakum. The
foot should then be bandaged, to keep out the dirt. If the horse
must be used during the day, remove the bandage while the
horse is at work, renewing the treatment after the day’s work
is over. . This treatment must continue until the frog is sound.

One of the serious conditions attending this disease is that
it is not a cause of lameness until it has reached a very serious
stage.

Canker is a disease of the sole and frog that is of germ
origin. The canker-germ usually does not attack a sound foot,
but is found to be a sequel to thrush or to a punctured wound of
the foot. If it originates in a puncture, it is noticed that the
wound does not heal, but becomes. more and more ageravated.
If it occurs independently of an injury, it is first noticed by its
offensive odor, the discharge from the cleft and sides of the frog,
and the rotting away of the sole. Surgery is the best treatment.

A corn is a blood-blister in the living tissues of the sole.
It is caused by a bruise to that part of the sole between the bars.
and the wall, where the sole is thinnest. If the horse goes lame
in one leg, without apparent cause, his shoe should be pulled,
and the seat of corn pared out. If, instead of showing white,
the sole shows a discolored spot, with reddish streaks—inflamed

ELEMENTS OF HIPPOLOGY. 131

capillaries—radiating from it, the trouble is froma corn. The
treatment is to cut out the sole immediately over the corn, to
keep the shoe from bearing on it.

The fore feet are almost exclusively subject to corns. While
in motion, the horse strikes the ground first with the heels of his
fore feet and with the toes of his hind feet.

If the seat of corn is repeatedly bruised, as is the case when
the shoe is left on too long, and the heel bears directly on the
seat of corn, it often suppurates, and the inflammation spreads
to the velvety tissue and the lamine. This is an uncommon
and extremely serious phase of the disease.

A bruised sole is a similar trouble, resulting Pa a severe
blow to the sole. It is very difficult to locate, and can only be
cured by rest, and, when suppuration results, by surgery.

Contracted heels isa common disease among all classes of
horses, but especially among saddle-horses. It is a result of
diseases that cause the destruction of the frog, or of a wasting
away of the frog from disuse, as in the case with horses habituall&
shod with calks. The heels, robbed of the support of the healthy
frog, pinch in together (Figure 86). The only remedy is to re-
store the frog, and usually this is impossible.

Cracked heels, or scratches, is a disease similar to the
familiar chapped hands. Its location is in the tender skin over
the heels and under the fetlock. It is easily recognized by
longitudinal cracks in the skin, showing red under at first. If
neglected, the fluids that escape will dry and form thick crusts
on each side of the cracks. The cracks often become infected
and suppurate. Similar cracks at the bend of the knee and
hock, called, respectively, malanders and salanders, some-
times appear, and, in certain badly neglected cases, these regions
unite, presenting a most loathsome aspect. Scratches are al-
most always caused by filth, neglect, or bad treatment, and are
cured by cleanliness and dryness. Extreme cases need expert
treatment.

132 ELEMENTS OF HIPPOLOGY.

A good treatment for the first stages of the disease is to
bathe the part untilit is clean, dry it well, and apply carbolized
vaseline locally. This dressing must be frequently changed, as
dust adheres to it and, if left on after it becomes caked with dust,
it may do more harm than good. The patient must be rested,
as the cracks open with each step the horse takes.

Horses that are tied by so long a rope that they can tangle
their hind (very rarely the fore) foot in it, will usually struggle
to free themselves, and often seriously chafe the tender skin under
the fetlock; such a chafe is termeda rope-burn. Because of
their position and the difficulty of keeping the part at rest, they
are tedious to heal, and, when healed, leave unsightly scars. Rope-
burns are merely blemishes when they heal without causing |
stiffness in the action. On account of their unsightliness, it is
best to prevent them by watching horses that are picketed out —
very carefully until they have learned how to avoid burning
themselves. In the stables, care should be taken that a horse
is tied short enough that he cannot get his hind foot over the rope.

Brushing, cutting, or interfering are names given to
indicate an injury to the fetlock of either a fore or hind foot,
done by striking the fetlock with the opposite foot. They are
caused by improper shoeing, weariness, or defective action, and
are prevented by proper shoeing or by the use of boots or so-
called interfering straps. |

Forging, or clicking, is the striking of the under side of
the shoe or the sole of the front foot by the toe of the hind hoof
or shoe on the same side. It is caused usually by defective ac-
tion. The front foot is slow in recovering from a stride and is
struck at the instant it is most bent to the rear. The theory
has been advanced that the horse does it willfully, because he
likes to hear the click as the shoes come together. It is corrected
by special shoeing.

Coronitis is the name for inflammation of the coronary
band. This disease is usually the accompaniment of some other
disease of the foot.

ELEMENTS OF HIPPOLOGY. 133

Wounds or bruises of the coronet are known by the general
name of treads, because they come usually from being stepped
on. ‘Treads are dangerous when they affect the extensor tendon,
or when they injure the joint between the coffin-bone and the
coronary-bone. A tread must be kept jvery clean, and infection

way, from the
sides and from beneath, and a malformation called false quarter
results.
A puncture is a wound to the foot, caused by a nail or
other sharp object being driven into the sensitive parts of the foot.
Any infection within the rim of the hoof, resulting in sup-
puration, forms an abscess that cannot drain downward. As

134 ELEMENTS OF HIPPOLOGY.

the pus accumulates it is forced upward usually until the sinus
reaches the rim of the coronary band, where an open sore re-
sults. Such a sore; a fistula, is called a quittor. Frequently,
in the history of quittors, the sole is finally penetrated by the
pus, and natural drainage results. A quittor is almost always
the result of neglect, and in its most frequent e is the result
of a neglected tread.

Cracks in the hoof running up and down are termed sand-
cracks when.in the toe—usually in the hind feet, and quarter- —
cracks when on the inside—usually on the front feet. The
outside of the feet is seldom cracked. Cracks are usually caused
by defective shoeing or by excessive dryness.

Sidebones are the ossifications resulting from inflamed
lateral cartilages. These cartilages help receive and distribute
the shock of impact. Inflammation causes bony deposits to
replace the cartilaginous tissue. These deposits often grow to
be noticeably large.

Navicular disease is the result of an injury to the navic-
ular-bone or to its coverings or attachments that either fractures
the bone or sets up destructive inflammation in it.

The navicular-bone is a little roller-shaped bone, lying in
the posterior angle between the lower pastern-bone and the
cofin-bone. The perforans tendon is fastened to the under side
of the coffin-bone. It bends over the navicular-bone, passes
behind the pastern, and, bending again over the sesamoids,
goes upward to its muscular development above the knee.

This tendon transmits much of the shock of impact. The
navicular-bone, pinched in between it and the other bones of
the foot, is subjected to tremendous pressure at every stride. »
Its surface must be smooth and well lubricated in order that the
tendon perforans may slip smoothly over it, in response to the
action of the muscles controlling it. If the pressure of the
tendon is too great for the health of the bone, it breaks, or
its envelope becomes inflamed and its structure changes. Its

ELEMENTS OF HIPPOLOGY. 135

surface becomes rough and chafes the sheath of the tendon,
and, as the bone is inaccessible to the surgeon, the evil done is
irremedial. Navicular disease is incurable and very painful.
In order to render the horse unconscious of this pain, and so
prolong its usefulness
until a complete break-
down occurs, a portion
of the sensory nerve sup-
plying the foot is re-
moved by an operation
called neurotomy.

‘““Tn the early stages of
navicular disease the
symptoms are generally
very obscure. When the
disease begins in inflam-
mation of the navicular
bone, the animal, while
at rest, ‘points’ the af-
fected foot a time before
any lameness is seen.
While at work, he ap-
parently travels as well
as ever, but when placed
in the stable, one foot is
set out in front of the
other, resting on the toe,
with fetlock and knee
flexed. After a time,
if the case is closely
watched, the animal takes a few lame steps while at work,
but the lameness disappears as suddenly as it came, and
the driver doubts if the animal was really lame at all. Later
on the patient has a lame spell, which may last during the greater

part of a day, but the next morning it is gone; he leaves the
stable all right, but goes lame again during the day. In time he
has a severe attack of lameness, which may last a week or more,
when a remission takes place, and it may be weeks or months

FIGURE 89.—PorIntTING A Tor FOR NAVICULAR DISEASE:

before another attack supervenes. Finally, he becomes con-
stantly lame, and the more he is used the greater the lameness.’’*

The polo-pony pointing his toe in Figure 89 went through
the phases described above exactly. The first long attack came

ELEMENTS OF HIPPOLOGY. 137

on during the early spring, and he recovered from it before the
polo seasoned open. He played a fast game every fine day during
the season. His second attack came on during the next winter
and lasted several weeks. The following spring he played well
for two months, and then went permanently lame.

Navicular dis-
ease does not
attack the hind
feet. (There are
but two cases on
record, according to

4G High ring bone Moller, an eminent
German veterinar-
ian.)

A ringbone
(Figure 90) is a
bony growth on the
: ankle. It is nota
a ae es disease in itself, but,
eral curHlege) | egal like bone spavin, is
a result of inflam-
mation in bone-
producing tissues.
Ringbones are
caused by blows,
sprains, overwork,
too fast work on
hard roads, jump-
ing, and the like. Horses whose pasterns are too short and up-
right are more liable to the disease that causes ringbone than
those with long, elastic pasterns.

The first symptom is lameness. A puff, hot and harder
than the ordinary wind-gall, is noticeable. The ringbones that
develop under the extensor tendon or near the navicular joint

FIGURE 90.

138 ELEMENTS OF HIPPOLOGY.

are the most distressing, and are almost sure to produce incurable
lameness. Those on the side of the bone, or high up on the
upper pastern, are sometimes called false ringbones, and do not
always cause lameness. A ringbone is difficult to diagnose in
its early stages, but in its full growth can be easily seen and felt.
The treatment for ringbone is the same as for spavin. If the
ringbone interferes with the action of the extensor tendon or the
navicular joint, recovery is impossible. A horse suffering from
ringbone in front points his foot by resting it on the heel.

Founder, or laminitis, is inflammation of the sensitive
lamine of the foot. Like all inflammation in soft tissues, it is
accompanied by congestion. The excess of blood fluids causes
great pressure to be brought on the outer face of the coffin-bone,
sufficient in very severe attacks to force that bone through the
sole, causing dropped sole. In acute attacks the horse gives
every evidence of suffering great pain. He is very lame, the
pulse and temperature rise rapidly. He breathes rapidly, with
nostrils open and heaving sides. He refuses food, but drinks
copiously. The coronets and ankles are hot and dry, and the
artery of the fetlock throbs noticeably.

If only one front foot is affected, he relieves that foot of as
much weight as possible by advancing it and resting it on its heel.
When urged forward, he either carries the lame foot in the air,
hopping from the other, or he puts it carefully forward on its
heel and quickly advances the other of the pair. He has great
difficulty in turning towards the side of the lame foot.

If both front feet are affected, the animal will be very hard
to move. He advances by cautiously planting the fore feet and
then quickly brings his hind feet well forward. When standing,
he rests his head on the manger or hangs it down nearly to the
floor.* e :

*The discussion of founder is condensed from Dr. A. A. Hol-

combe’s article on Diseases of the Fetlock, Ankle, and Foot, ‘ Diseases
of the Horse,” p. 417, et seq.

ELEMENTS OF HIPPOLOGY. 139

If the hind feet are affected, they are planted well to the
front to bring the weight on the heels, and the fore feet are car-
ried back, supporting as much of the weight as possible. It is
extremely difficult for a horse foundered behind to move az all.
All four feet are seldom affected at the same time.

In mild cases the attacks last but a day or two. More
serious cases run their course in one to two weeks. The more
often the cases recur, the longer will be the period of recovery.

The causes of founder are many and apparently unrelated.
Concussion is a prolific cause; over-exertion when tired, and ex-
haustion, are equally prolific. Rapid changes of temperature—
sudden cooling after becoming very hot, either by watering the
horse copiously, or by standing him uncovered in a draft—is a
very common cause and the one most easily prevented. Neglect
of ‘cooling out’’ a hot horse in summer might cause laminitis;
in the winter the same neglect would be more apt to cause con-
gestion of the lungs, followed by pneumonia.

Chronic laminitis is the result of continued attacks of lam-
initis. There is always fever in the feet. Due to the inflam-
mation, more horn is deposited than the hoof needs; it is of poor
quality, and the hoof becomes misshapen and scaly. Rings,
showing this morbid growth, appear in the hoof. These rings
usually correspond to each acute attack. They are roughly
parallel to the coronet, as shown in Figure 91. The altered
position of the coffin-bone is also shown there. These rings are
easily distinguished from the grass rings in a healthy foot, re-
ferred to in the last chapter.

Seedy toe is a cavity in the horn, usually in the toe, due to
a loss of secreting power in the lamine. It is usually a result
of founder.

The anatomy of a horse is such that the muscles of the fore-
leg are at rest when he is standing squarely on both front legs.
This is not true behind, where he supports his weight alternately
on each leg, resting the other on its toe.

140 ELEMENTS OF HIPPOLOGY.

A horse that does not stand squarely on a front foot is said
to point it. If he points it on the toe, the trouble will be found
in the flexor tendon, or on some tissue that it works against, not
in the lamine. Hence, a horse pointing on his toe is suspected
of navicular disense or strained back tendons. A horse having
corns would point on the toe. If he rests it on the heel, it is to
relieve pain in the lamine or under the extensor tendon, and he
is suspected of founder or ringbone. |

CHAEPER iXtT.

THE PRINCIPLES OF HORSESHOEING FOR HORSES
WITH ORDINARY FEET.*

As has been shown in Chapter X, the horse renews his hoof
in about eight months; and that the surplus growth of the horn
of the wall must be removed, either by the wear resulting from the

_ natural movements of
ithe horse, or by arti-
‘| ficial means, while the

sole and frog scales off
of itself when no long-

The horn of the

quite enough protec-

sues beneath while the
horse is at pasture, is
not sufficient while he
is at work, and the
artificial protection of
the horseshoe is neces-

FIGURE 92.—APPEARANCE OF ASHOE, sary.

The shoe protects
the wall from wear, and consequently is carried by the wall,
in the latter’s growth, away from the sole. The wall

grows much faster at the toe than at the heel, dragging
the shoe forward slightly, and gradually changing the angle
the coffin-bone makes with the pastern-bone. This has the ef-
fect of diminishing the work of the extensor tendon at the ex-
pense of the flexor tendon. Not only is this equilibrium de-
stroyed by leaving the shoe on too long, but the heel of the shoe

FigurE 93.—SHOE on Too Lone

oradually bears more and more on the seat of corn, rendering
lameness from corns extremely liable.

Experience teaches that four weeks is the safe limit to leave
the shoe on without re-seating it. This gives importance to the
first rule in the care of the horse’s feet:

All shoes to be removed at the end of a month’s wear.

HLEMENTS OF HIPPOLOGY. 143

Figure 93 shows a shoe that has been on about seven weeks.
The frog has shrunken and the shoe is brought forward. The
worn appearance of the toe would lead to the belief that the
horse is a stumbler.

All shoes have the fault of preventing the natural expansion
and contraction of the foot, due to the elastic action of its tissues.
To restore this elasticity and to rest the foot, the following rule
should always, when possible, be observed:

After shoes are removed, the horse should, if prac-
ticable, be left barefoot for twenty-four to forty-eight
hours.

_ Proper use, proper feeding, and proper shoeing understood,
no practice will prolong the period of usefulness of a horse, or
do as much to prevent lameness, as this one.

Any stableman of intelligence can be shown in an hour
how to take off shoes properly. It is an easy matter, the day
before a horse is to be shod, for the stableman to take off his
shoes and pinch off the surplus wall. Even if he must be shod
the next morning, the rest over night will do him much good.

Before removing the old shoe, each clench should
be carefully and fully raised (Figure 94).

The careful and complete raising of each clench is necessary
to avoid injury to the crust. If the clench is not raised, a part
of the crust will be torn away as the nail is drawn, andthe wall
weakened by so much.

After raising the clenches, the blacksmith next loosens the
shoe with the pincers, beginning at the heel. When all the nails
but the front one on one side are loosened, he begins at the other
heel, working towards the toe again. Having loosened all the
nails but the front ones, he seizes the shoe at one of these nails
and pries towards the heel. If the blacksmith finds the shoe
coming off ‘‘hard’’ he should examine it to see that two or more
of the nails have not been driven obliquely, in which case there

144 ELEMENTS OF HIPPOLOGY.

is danger of pulling out a wedge-shaped portion of the crust.
In such a case the nails must be pulled separately.

The seat of the newly-set shoe is on the wall at the level of
the sole, bearing slightly on the sole. This surface must be pre-
pared most carefully for the ange by oe it off so that it is a
perfect plane and at
right angles to the
axis of the foot. In
lowering the wall the
following rule should
be strictly adhered to:

The wall to be low-
ered to the level of
the sole with the
pincers, never with
a knife.

A line can be follow-
ed better and easier
with cutting pincers
than with a _ knife.
More than that, the
proper use of the pin-
cers insures that the
wall will be brought
down evenly to the
sole all around.

In the mechanical part of the shoeing it is of the highest de-
gree important that the shoe be put on so that the foot will rest
squarely on the ground, and also that the normal height at heel
and toe be maintained. The blacksmith, after he has levelled
the foot to the sole all around, should put the foot on the floor
and verify its bearing before going further. He should also
carefully observe any unusual thing in the conformation of
the,foot. ”

FicurRE 94.—CLENCHES RAISED.

Rasp the wall down level with the sole. -

This is to remove the irregularities left by the pincers, and
insure for the shoe a bearing surface on both sole and wall.
When the surface has been made level, blunt the sharp outer
edge of the crust with the rasp.

It has been advocated that the elasticity of the horse’s foot
is increased by cutting away the bars—‘‘ opening out the heels,”’
- itis called. This practice is common enough to make necessary
the following rule:

The bars are not to be cut away.

The bars are Nature’s support against contraction of the
heels and must on no account be cut away. Nor must the sole
in the space between the bars and the wall be cutaway. This
filling-in of the interspace acts as a support to the bars and wall
against contraction of the heels. The practice of opening the
heels cannot be too severely condemned.

The frog, if healthy, is not to be pared or even
trimmed.

The frog, like the sole, requires only to be let alone. It is
Nature’s pad, or cushion, to lessen concussion in the upper struct-
ures when the foot comes to the ground. It can never grow
too big. It thrives on concussion. If pared, and thereby de-
prived of use, it dwindles away.

The frog, when well developed, also acts as a stay against
slipping. A good sound frog is a better stay than calks. If
the frog has becorhe injured and is ragged, the ragged parts only
should be carefully cut away.

Do not burn out a seat for the shoe with a hot shoe.

The seat of the shoe may be lightly touched with the hot
shoe to mark its inequalities. The marked portions should then
be rasped down. To burn out a seat for the shoe dries up the
horn of sole and wall, kills living cells that are necessary to the
strength of the hoof, and causes the sole to dry out and shrink

apg

146 ELEMENTS OF HIPPOLOGY.

away from the shoe. It is a bad practice that is resorted to
only by lazy horseshoers. It should not be tolerated. ;
Figure 95 shows a foot that has been prepared for its shoe
in a very common way, but in a way that violates the last three
principles. The sole
has been pared out,
the wall cut down too
much, the frog trim-
med, the bars cut
away, and, to com-
plete the iniquity, the
seat for the new shoe
has been burned out.

All of these abuses
‘are easy of detection,
except the last, by a
very casual inspection
of the shod horse.

All shoes should
be flat to the sole,
not seated in.

The front nail on each side should be in the anterior portion
of the quarter, and the other nails should equally divide the
distance to the heels. This rule is a flexible one.

When a nail has been driven, the point should immediately
be twisted off, to prevent possible blemishes to the other feet in
case the horse should struggle. After the nails are all driven,
the clenches are turned slightly and evened with the rasp, to
make them, the same length. A slight groove is then made on
the under side of the clenches in the horn and the clenches bent
into the groove. : :

Clenches should not be rasped after being turned

They should be carefully flattened with the hammer. Any
filing, in addition to injuring the enamel, lessens the power
of holding.

Except to make this groove for the clenches, the rasp should
not be used on the outside wall of the foot. Roughness in the
clenches can be smoothed by light taps of the hammer. Rasping
the outside of the hoof removes the enamel that is there to keep
the foot from losing its moisture by evaporation; in the subse-
quent drying and shrinking the hoof is often cracked.

The shoe should be neither too large nor too small, but
should fit the outside of the hoof perfectly in front of the rear-
most nails. In rear of these nails the shoe should gradually
broaden, to keep the ends from bearing on the seat of corn as

dumping and thereby greatly weaken the wall. The nails,
too, are driven too near the sensitive tissues, and there is danger
of pricking. Even if the nails do not actually reach the sen-

150 ELEMENTS OF HIPPOLOGY.

The following extract from the article by John W. Adams,
A.B., V.M.D., found on pages 565-569, ‘‘ Diseases of the Horse,”’
gives an outline of the properties of horseshoes, and the special
peculiarities of the chief classes of shoes:

“The shoe is an artificial base of support, by no means ideal,
because it interferes, to a greater or less degree, with the physiology
of the foot, but indispensable, except for horses at slow work on soft
ground. Since a proper surface of support is of the greatest import-
ance in preserving the health of the feet and legs, it is necessary to
consider the various forms of shoes best adapted to the different forms
of hoofs. Certain properties are common to all shoes and may be
considered first. They are form, width, thickness, length, surfaces,
borders, fullering, nail-holes, and clips.

“ Form.—Every shoe should have the form of the hoof for which
it is intended, provided the hoof retains its proper shape; but for every
hoof that has undergone change of form we must endeavor to give
the shoe that form which the foot originally possessed. Front shoes
and hind shoes, rights and lefts, should be distinctly different and
easily distinguishable.

“Width.—All shoes should be wider at the toe than at the ends
of the branches. The average width should be about double the
thickness of the wall at the toe.

“ Thickness.—The thickness should be sufficient to make the shoe
last about four weeks and should be uniform, except in special cases.

“Length.—This will depend upon the obliquity of the hoof,
viewed in profile. The acute-angled hoof has long over-hanging heels,
and a considerable proportion of the weight borne by the leg falls in
the posterior half of the hoof. For such a hoof the branches of the
shoe should extend back of the buttresses to a distance nearly double
the thickness of the shoe. Fora hoof of the regular form, the branches
should project an amount equal to the thickness of the shoe. Ina
stumpy hoof, the shoe need not project more than one-eighth of an
inch. In all cases the shoe should cover the entire ‘bearing surface’
of the wall.

“ Surfaces.—The surface that is turned toward the hoof is known
as the ‘upper,’ or ‘hoof surface,’ of the shoe. That part of the hoof
surface which is in actual contact with the horn is called the ‘ bearing

ELEMENTS OF HIPPOLOGY. 151

surface’ of the shoe. The ‘bearing surface’ should be perfectly hor-
izontal from side to side and wide enough to support the full thick-
ness of the wall, the white line, and about an eighth of an inch of the
margin of the sole. The ‘bearing surface’ should also be perfectly
flat, except that it may be turned up at the toe. The surface be-
tween the ‘bearing surface’ and the inner edge of the shoe is often
beaten down or concaved to prevent pressure too far inward upon the
sole. This ‘concaving,’ or ‘seating,’ should be deeper or shallower as
the horny sole is less or more coneave. As a rule, strongly ‘cupped’
soles require no concaving (hind hoofs, narrow fore hoofs).

“ Borders.—The entire outer border should be beveled under the
foot. Such a shoe is not so readily loosened, nor is it so apt to lead
to interfering.

“ Fullering.—This is a groove in the ground surface of the shoe.
It should pass through two-thirds of the thickness of the shoe, be
clean, and of uniform width. It is of advantage in that it makes
the shoe lighter in proportion to its width, and, by making the ground
surface somewhat rough, tends to prevent slipping.

“ Nail- Holes.—The shoe must be so punched that the nail-holes
will fall directly on the white line. They should be confined to the
fore half of front shoes, but may occupy the anterior two-thirds of
hind shoes. For a medium-weight shoe three nail-holes in each
branch are sufficient, but for heavier shoes, especially those provided
with long calks, eight holes are about right, though three on the in-
side and four on the outside may do.

“ Clips.—These are half-circular ears drawn up from the outer
edge of the shoe, either at the toe or opposite the side wall. The
height of a clip should equal the thickness of the shoe, though they
should be even higher on hind shoes and when a leather sole is in-
terposed between sole and hoof. Clips secure the shoe against shifting.
A side clip should always be drawn up on that branch of the shoe that
first meets the ground in locomotion.

152 ELEMENTS OF HIPPOLOGY.

“SPECIAL PECULIARITIES OF THE CHIEF CLASSES
OF SHOES.

“1. A shoe for a regular hoof fits when its outer border follows
the wall closely in the region of the nail-holes, and from the last nail
to the end of the branch gradually projects beyond the surface of the
wall to an eighth of an inch, and extends back of the buttresses an
amount equal to the thickness of the shoe. The shoe must be straight,
firm, air-tight, its nail-holes directly over the white line, and its
branches far enough from the branches of the frog to permit the
passage of a foot-pick. Branches of the shoe must be of equal length.

“Tn fitting a shoe to a hoof of regular form, we follow the form
of the hoof; but in base-wide and in base-narrow hoofs, which are of
irregular form, we must pay attention not only to the form of the
hoof, but also to the direction of the pasterns and the consequent dis-
tribution of weight on the hoof, because where the most weight falls
the surface of support of the foot must be widened, and where the
least weight falls (opposite side of the hoof) the surface of support
should be narrowed. In this way the improper distribution of weight
within the hoof is evenly distributed over the surface of support.

“2. A shoe for a base-wide hoof should be fitted full on the
inner side of the foot and fitted close on the outer side, because the
inner side bears the most weight. The nails in the outer branch are
placed well back, but in the inner branch are crowded forward toward
the toe.

“3. A shoe for a base-narrow hoof should be just the reverse of
the preceding. The outer branch should be somewhat longer than
the inner.

“4. A shoe for an acute-angled hoof should be long in the branch-
es, because most of the weight falls in the posterior half of the foot.
The support in front should be diminished either by turning the shoe
up at the toe or by beveling it under the toe.

“5. A shoe for a stumpy hoof should be short in the branches,
and, for pronounced cases, should increase the support of the toe,
where the most of the weight falls, by being bevelled downward
and forward.

“In many cases, especially in draft-horses, where the hoofs stand
very close together, the ccronet of the outer quarter is found to stand
out beyond the lower border of the quarter. In such cases the outer

ELEMENTS OF HIPPOLOGY. 153

branch of the shoe from the last nail back must be fitted so full that
an imaginary perpendicular dropped from the coronet will just meet
the outer border of the shoe. The inner branch, on the other hand,
must be fitted as ‘close’ as possible. The principal thought should be
to set the new shoe further toward the more strongly-worn side.
Such a practice will render unnecessary the widespread and popular
fad of giving the outer quarter and heel-calk of hind shoes an extreme
outward bend. Care should be taken, however, that in fitting the
shoe ‘full’ at the quarter the bearing surface of the hoof at the quarter
be not left unsupported or incompletely covered, to be pinched and
squeezed inward against the frog. This will be obviated by making
the outer branch of the shoe sufficiently wide and punching it so coarse
that the nails will fall upon the white line ”

THE HEART, LUNGS, AND AIR-PASSAGES.

The heart is the organ by which the blood is circulated
through the body. It hangs a little to the left of the center of
the forward part of the chest, suspended from the vertebra of
the withers, the small end downwards. Its average weight is
from seven to eight pounds.

The heart is of interest to the amateur horseman because of
the influence disease has on its action. In health, the heart of
the ordinary horse pulsates from thirty-five to forty times a
minute; the thoroughbred horse, from forty to forty-five. These
pulsations of the heart send the blood through the arterial
system in a series of waves, each wave corresponding to one
pulsation of the heart. These waves constitute what is called
the pulse, and it is by counting the pulse and by observation of
the relative strength and frequency of the waves of the pulse
that the heart-action of the horse is verified.

It must be understood that the number of pulsations above
noted is for the animal at rest, or when not undergoing any
special exertion. The pulse will become higher during exertion,
the amount of the increase depending on the extent of the ex-
ertion. The pulse will be higher in horses kept in fine condition,
in warm stables, and fed on selected forage, than in animals
more roughly stabled and fed. It is higher in young horses
than in old ones. Fear or excitement also tend to augment
the pulse. 3

When the animal is at rest, a pulse of from 50 to 55 indi-
cates a feverish condition, the cause of which should be inves-
tigated. From 70 to 75 beats a minute indicates a very serious
condition, demanding prompt and energetic action.

156 ELEMENTS OF HIPPOLOGY.

The arteries, where the pulse is felt, are the deep-seated
blood-vessels; the veins lie nearer to the surface. There are
several places where the larger arteries come close enough to
the skin to be felt, but the best place to take the pulse is on the
under side of thé angle of the under jaw, where an artery bends
around the bone. The pulse can also be counted by placing
the hand against the side.

‘““The temperature of the horse is determined roughly by
placing the fingers in the mouth or between the thighs, or by
allowing the horse to exhale against the cheek or back of the
hand. In accurate examination, however, these means of de-
termining temperature are not relied upon, but recourse is had
to the use of the thermometer. The thermometer used for
taking the temperature of a horse is a self-registering clinical
thermometer, similar to that used by physicians, but larger,
being from five to six inches long. The temperature of the
animal is measured in the rectum. |

“The normal temperature of the ‘horse varies somewhat
under different conditions. It is higher in the young animal
than in the old and is higher in hot weather than in cold. The
weather and exercise decidedly influence the temperature, physi-
ologically. The normal temperature varies from 99.5 to 101
degrees Fahrenheit. If the temperature rises to 101.5, the horse
is said to have a low fever; if the temperature reaches 104, the
fever is moderate; and if it reaches 106, it is high. Above this
point it is regarded as very high. In some diseases the tem-
perature goes as high as 108 or 110 degrees. In the ordinary in-
fectious diseases it does not often exceed 106. A temperature
of 107.5 degrees and above is very dangerous, and must be
reduced promptly if the horse is to be saved.’’*

“The lungs are the essential organs of respiration. They
consist of two (right and left) spongy masses, commonly called

*Page 17, ‘‘ Diseases of the Horse,’’ Bureau of Animal Industry,
1903

ELEMENTS OF HIPPOLOGY. 157

the lights, situated entirely within the thoracic cavity. On
account of the space taken up by the heart, the left lung is the
smaller. Externally, they are completely covered by the pleura.
The structure of the lung consists of a light, soft, but very
strong and remarkably elastic tissue, which can only be torn
with difficulty. Each lung is divided into a certain number of
lobes, which are subdivided into numberless lobules (little lobes).
A little bronchial tube terminates in every one of these lobules.
The little tube then divides into minute branches, which open
into the air-cells of the lungs. The air-cells are little sacs, having
a diameter varying from one-seventieth to one-two-hundredth
of an inch; they have but. one opening, the communication with
the branches of the little bronchial tubes. Small blood-vessels
_ ramify in the walls of the air-cells. The air-cells are the con-
summation of the intricate structures forming the respiratory
apparatus. They are of prime importance, all the rest being
complementary. It is here that the exchange of gases takes
place. As before stated, the walls of the cells are very thin;
so also are the walls of the blood-vessels. Through these walls
escapes from the blood the carbonic acid gas that has been ab-
sorbed by the blood in its circulation through the different parts
of the body; and through these walls is absorbed, by the blood
from the air in the air-cells, the oxygen-gas, which is the life-
giving element of the atmosphere.”’*

The nasal passages, or nostrils, unite above the back of the
mouth, forming the pharynx. The pharynx is a box-like
organ, through which the food passes into the gullet, as well
as the air into the lungs. The nostrils and mouth open into it
in front, nostrils above, and the gullet and windpipe lead from
it in rear, the windpipe below. To guard against the introduc-
tion of food into the windpipe, a large valve, 2 (Figure 98),
closes it, that is hinged below and that lies, when the horse is

*Pages:119 and 120, “ Diseases of the Horse,’’? Bureau of Animal
Industry, 1903.

158 ELEMENTS OF HiPPOLOGY.

not eating, over the opening into the mouth. Food entering
the pharynx from the mouth pushes this valve into place over
the windpipe and passes over it into the gullet. For this reason
a horse always must breathe through its nose, as air entering
the pharynx through the mouth has the same effect as food of
stopping the windpipe; hence it is important never to call on
an animal for sudden or energetic action when there are particles
of food in his pharynx that may be suddenly drawn into his
lung, causing him to choke.

Back of this valve lies the larynx, containing the vocal
cords; this in turn opens into the windpipe, which separates,
in the chest, into two branches leading to the right and left
lungs (Figure 98).

In the lungs these branches divide into bronchial tubes
(Figure 98), which, by repeated ramifications, terminate in air-
cells, where the process of purifying the blood takes place.
These air-passages are all lined with mucous membrane, which
secretes a slimy fluid called mucous, which, when discharged
from the nostrils, is called phlegm.

When, for any reason, this membrane becomes acutely in-
flamed, a disease exists, which is variously named, depending
upon its location in the air-passages.

In the nostrils or pharynx it is called cold in the head; in
the larynx and windpipe, laryngitis, or sore throat; in the
branches of the windpipe and the bronchial tubes, bronchitis.
If the substance of the lungs becomes inflamed, the disease is
known as pneumonia.

Lining the chest and covering the lungs are two membranes,
called the pleurge. They are fast to the lungs and chest, re-
spectively, but are completely separated from each other. A
lubricant is secreted by each that flows between them, making
it easy for them to slip on each other as the lungs are enlarged
and contracted. If they become inflamed, the disease is pleu-

risy. Bronchitis, pleurisy, and pneumonia are allied dis-
eases and rarely exist separately.

Congestion of the lungs is an engorgement of the capil-
laries of the lungs with blood, caused by over-exertion, or sudden
chilling after heating work. The lungs cannot purify the blood
fast enough, and, unless the congestion is arrested, the horse
dies of suffocation.

When a horse has been driven or ridden very fast for a
longer period than should have been the case, the severe strain
put upon the diaphragm by the extra exertion will cause violent
spasmodic contractions of that muscle. This condition is called
thumps, and is similar in origin to the familiar hiccoughs.
Usually the flank is shrunken, and the posterior angle of the ribs
thrust outwards. The jerky motion caused bythe spasm shakes
the whole body. The pulse is not accelerated in thumps; it
often is weaker than normal. If not relieved, death usually
results.

If the disease appears while the animal is on the road, he
should be stopped at once; the saddle or harness should be re-
moved, and the body and legs should be briskly rubbed to draw
as much of the circulation to the skin as possible. .As many
persons as are available should be put at this work. Whenthe —
body has become warm and the spasms relax, the patient should
be warmly blanketed and should be put in the nearest box-stall,
out of drafts. Two or three days’ careful nursing will usually
complete the convalescence.

Thumps attacking a horse on the road is always caused
by injudicious use. Thumps may be followed by congestion
of the lungs, especially in the winter, or by founder in the
summer. | 7

These are all acute diseases. From repeated attacks, the
membranes become thickened or their vitality becomes im-
paired, and certain chronic diseases result.

Thick wind is the name for the chronically diseased and
thickened condition of the smaller bronchial tubes. The amount
of blood that can be purified is limited by this disease, and the
horse shows distress and labors when worked fast or hard. He
seems to struggle for his wind—to gasp for breath. It is not
accompanied by noise, and the inhalations and exhalations recur
at equal intervals. There is no medical treatment for this dis-
ease. If the horse is very carefully fed, is not exercised at all
while his stomach is full, and is worked lightly and at slow
gaits, he may finally recover partially, and gradually become
more and more serviceable. .

Broken wind or heaves is caused either by a rupture of the
air-cells, or by a partial paralysis of the muscles of the cells that
assist in expelling the air. In this disease the ordinary action
of the lungs and diaphragm is not enough to clear the lungs,
and a second contraction is necessary.

The diaphragm is a dome-shaped muscle, rising from the
abdomen into the hollow of the chest. By its muscular action
the lungs are squeezed against the ribs and the air thus mechan-
ically pushed out of them. With the withdrawal of the dia-
phragm the lungs expand and follow it, and so fill themselves
with the fresh air that is so necessary to the life of the animal.
If the stomach is overloaded with coarse food, the diaphragm
will be mechanically and constantly pushed against the lungs,
and so limit their powers of expansion. While this condition
exists, if the animal is called on for any extra effort, the lungs
will not respond to the demands made on them by the circula-
tion, and the cell walls will be ruptured in consequence. When
the processes of digestion remove the obstruction to the lungs’
proper action, the evil will still remain. The lung-cells that
have been ruptured will leak air into the lung tissue itself, and
this air is expelled with difficulty. Horses living in a dusty or
badly-ventilated stable are predisposed to heaves. The lungs,
being constantly irritated, become chronically inflamed, and the

ELEMENTS OF HIPPOLOGY. 163

muscles of the cell walls lose their elasticity or become partially
paralyzed.

Broken wind is easily distinguished from other lung
disease by the double effort to exhale air, usually accom-
panied by a hacking cough. The period of exhalation is longer
than the period of inhalation. Heaves, except in very mild,
recent cases, is incurable, and the horse is greatly disabled by it.

Roaring is a disease that is characterized by a peculiar
noise made by the horse at inhalation. The noise called roaring
may be made by a sound horse when excited, or when suddenly
put to exertion after a period of idleness, or on account of a
cramped position of the head or neck. This noise is not accom-
panied, in the sound horse, by evidences of fatigue and ina-
bility to perform work, as is the case in the unsound horse.
Chronic roaring is the result of a paralysis of the muscles of the
larynx that control the vocal cords. This paralysis prevents
them from being opened sufficiently wide to admit air without
vibrating. Often a horse may be affected by the disease—par-
alysis of the vocal cord — without the accompanying sound.
This can be detected by making a sudden motion towards the
flank with the hand or whip, when the unsound animal will
erunt or groan. Roaring is very disabling, and can be cured
only by a surgical operation. This operation consists in re-
removing the vocal cord that has become uncontrollable.

Whistling is a variation of the sound made by aroarer. A
horse with a severe sore throat may make a whistling sound at
inhalation. This should not be considered as evidence that he
is a roarer until the sore throat is cured, when, if the horse is
sound, the whistling will cease.

A sound horse should breathe noiselessly and easily in all
emergencies. A horse that makes any noise or has any diffi-
culty in its breathing, no matter how slight, should not be
considered sound.

THE DIGESTIVE APPARATUS.

The digestive apparatus consists of the mouth, the gullet,
the stomach, the large and small intestines, and certain
other organs, into whose functions it is not necessary to in-
quire in so elementary a treatise as this one. These organs ex-
cept, of course, the mouth and a portion of the gullet, are con-
tained in the abdominal cavity.

The food is taken by the lips and is worked back to the
upper part of the mouth bythe lips and tongue. There it is
masticated by the molar teeth and mixed with saliva secreted
by the salivary glands. This is the first process of digestion.
When the mouthful has been well broken up and saturated
with saliva, it is passed back through the pharynx and gullet
to the stomach. This is a small organ, having a capacity of
' three to three and a half gallons. Two-thirds of the lining of
the stomach is a membrane that secretes gastric juice. The
food is slowly mixed in the stomach with this liquid until: it
partially changes its character, and is passed into the small in-
testine, to be there mixed with the digestive juices of the liver,
spleen, and other intestinal glands, to be transformed by the
chemical action of these reagents until it is ready to be absorbed
into the system.

A system of vessels, called lacteals, and the veins, absorb
the nutritive part of the food thus transformed and carry it to
a large vein near the heart, where it is poured into the blood.
This fluid, thus enriched, is carried by the circulation to all parts
of the body to nourish it and repair waste tissues. The débris
of digestion is forced through the large intestine and is voided
as dung.

166 ELEMENTS OF HIPPOLOGY.

Water takes a different course. It passes almost directly
through the stomach and small intestine to the water-sac or
cecum, where it is stored for use. A portion is drawn off to be
mixed with the blood to supply the fluids of the system; the
rest, carrying with it certain salts necessary to be removed from
the body, is excreted through the kidneys as urine.

The horse is an animal requiring regularity in feeding and
watering and a very limited variety of foods to be kept in effi-
cient condition. The horse’s stomach is very small; in propor-
tion to his bulk, it is only half the size of the human stomach.
It rests upon the large intestine and against the diaphragm,
while the small intestines lie further back in the abdomen, more
remote from the direct action of the diaphragm. The walls of
the stomach are elastic, and permit it. to accommodate itself to
the bulk of the food that enters it.

The above considerations render it imperative that a horse
should not be called on for severe work or rapid exercise imme-
diately after eating a bulky meal. The stomach, distended, in-
terferes with the free action of the diaphragm, and the latter,
in its efforts to increase the air capacity of the lungs, squeezes
the stomach back against the intestines, and so greatly impedes
the processes of digestion.

Very fortunately, digestion is a rapid process in the horse,
and the stomach is called on to do but little of the dige>tion of
the bulkier foods. Water is retained in the stomach or small
intestines only when it is absorbed by partially-digested food.
This has the effect of diluting the digestive fluids, of delaying
the process of digestion, and of mechanically removing from the
stomach food that is not ready to be passed to the intestine. In
addition, the water cools the stomach and its contents below
the temperature at which it best performs its functions. For
these reasons horses should not have access to water while
eating, or for an hour or two after.

ELEMENTS OF HIPPOLOGY. 167

Hay requires to be thoroughly chewed and mixed with
saliva before it cin be swallowed. When it reaches the stomach
it is delayed there but a short time, and passes tothe small in-
testine, where the greater part of its digestion is performed.
If a horse is fed only hay, the first portion of his meal passes
into the intestine very soon, but the stomach retains the suc-
ceeding portions for a longer time, and it is several hours before
the stomach is empty. In this way the muscles of the stomach
get the necessary amount of exercise to keep them in proper
condition.

Oats, however, and other concentrated foods are digested
almost entirely in the stomach; when they pass into the in-
testine much of their bulk is rapidly absorbed by the lacteals,
and there is little left for the intestine to work on. The result
is that the horse is still restless and hungry. If this one-sided
ration is continually given him, he will fall off faster than he
would do if fed hay alone, and this in spite of the fact that oats
contain more elements of nourishment than hay does. Horses
given an insufficient amount of hay will eat their bedding, or
any rough food they can get, to satisfy the craving for intestinal
exercise. Poor hay—that is not musty or dusty—and wheat,
rye, or barley straw, although they may contain practically no
nourishing qualities, will preserve the strength and health of a
horse in a remarkable degree. On this account horses on cam-
paign, or in places where good hay is hard to get, ought always
to be provided with rough forage of some sort, no matter how
poor in nourishing qualities.

The normal processes of digestion must not be interfered
with, or sickness or debility will result. A certain amount of
the digestion of food is done in the mouth, where the chemical
action of the saliva prepares the food for the further action of
the stomach. In order that the saliva can reach every part of
each mouthful of food, it must be broken up by the teeth. This
process is necessarily done in the case of hay, but oats are al-

ready fine enough to be swallowed and their smooth hulls offer
no obstacle to that process. These hulls are insoluble in the
juices of the stomach, and, if the oat grain has not been crushed
by the teeth, the kernel of the grain passes through the horse
unchanged. If it is imperfectly crushed, it will be only partially
digested in the stomach, and will pass on to the intestines, to
ferment there and to generate gases there that will cause distress -
and often disease. :

Owing to the uniformity in diet and the regular hours of
feeding, labor, and rest of most well-kept horses, diseases of the
digestive apparatus are comparatively infrequent among that
class of horses. They are the most easily preventable of all
equine diseases. Unfortunately, many horses are. not well kept,
and, as a result, ‘‘the disease of the horse that is most frequent-
ly met with is what is termed colic. This term is applied
loosely to almost all diseases of the abdomen that are accom-
panied by pain. If the horse evinces abdominal pain, he is
likely to be put down as suffering with colic, no matter whether
the difficulty be a cramp of the bowel, an internal hernia, over-
loading of the stomach, or a painful disease of the bladder or
liver.

“The general symptoms of abdominal pain, and therefore —
of colic, are restlessness, cessation of whatever the horse is about,
lying down, looking around towards the flank, jerky switching
of the tail, stretching as if to urinate, frequent changes of posi-
tion, and groaning. In the more intense forms the horse plunges
about, throws himself down, rolls, assumes unnatural positions,
as sitting on the haunches, and grunts loudly. Usually the pain
is not constant, and during the intermissions the horse may eat
and appear normal. During the period of pain, sweat is poured
out freely. Sometimes the horse moves constantly in a circle.
The respirations are accelerated, and usually there is no fever.”

ELEMENTS OF HIPPOLOGY. 169

From the above quotation* it is easily seen that grave er-
rors might be made in attempting to set down a specific treat-
ment for colic. The best treatment, for the non-professional
person, is to get the patient free from all harness, in a roomy
box-stall with plenty of bedding, so that he will not hurt himself
_ in his spasms of pain—and send for a veterinary surgeon.

Indigestion, or catarrh of the stomach or intestines,
is a much more common disease than colic, but it usually does
not exhibit such violent symptoms. The mucous membrane is
the general lining membrane of the digestive and respiratory
apparatus. Inflammation of this membrane impairs the di-
gestive ability of the organs inflamed, and the animal suffers a
loss of vitality in direct proportion to the extent of the disease.
The symptoms of the disease are an irregular and depraved ap-
petite and a loss of condition. The animal may show colicky
symptoms in extreme cases. The bowels are irregular, and the
dung contains much of the horse’s food that is unchanged by its
passage through the animal’s body. The horse’s skin seems
very tightly stretched, and the abdomen is ‘‘tucked up.”

Indigestion is due to numerous causes; anything that ir-
ritates the mucous membrane may cause it. Feeding improper
food, bad teeth, causing imperfect mastication, working a horse
immediately after eating—all are prolific causes of indigestion. fT

Lampas, the undue swelling of the membrane covering
the forward part of the roof of the horse’s mouth, is more an
indication of disease than a disease. Treatment of the swelling
itself does little good. The cause is usually with the horse’s
diet or digestion. The old practice was to burn the swellings
with a red-hot iron; such a treatment simply aggravates the

one that should be prevented. It will be discussed more at length

disease and adds to the pain. It should never be allowed.
Some veterinarians still advocate cutting the roof of the mouth,
believing that a little local blood-letting will relieve it. As the
cause of the disease is elsewhere, a better practice is to try to
find it and correct it. This is more the work of the professional
than of the amateur. The existence of lampas does not neces-
sarily indicate a serious condition. A day or two of rest and a
few bran-mashes will usually effect a cure.

It is hardly ever advisable for the amateur to attempt to
treat diseases of the vital or digestive organs. He will more
often injure than help the animal. Rest, good food, and san-
itary surroundings are far better than drugs in the hands of men
not thoroughly posted on their properties and effects.

CHAPTER-~XV.

STABLE MANAGEMENT.

The term ‘“‘stable management’’ includes the art of
proper stabling, sanitary care, feeding, watering, groom-
ing, and nursing of horses.

Stabling and Sanitary Care.—The first requisite for a
stable is to provide shelter from inclement weather. In far too
many stables this seems to be the only object in view. Of
almost equal importance to the item of shelter, for the robust
health of the occupants, are ventilation, dryness, and cleanliness.

EKeonomy of air-space is always sought for in stables. The
horses are kept in stalls that usually are only large enough for
the animal to stand or lie in. All available space in the stable
is used for passageways and for storage of forage and equipment
of all sorts; no space is wasted. That horse is lucky in a large
stable who has as much air-space as the man who grooms him
has in his quarters, although six or seven times his weight.*

It is, therefore, of the greatest importance that ample fa-
cilities for ventilation exist.

A horse needs shelter to best preserve his strength,
but he does not need his shelter heated artificially.

In order to keep horses’ coats short and glossy in the winter,
owners generally blanket them. Many, in addition, heat their
stables. The latter is, in most parts of the United States, un-
necessary; but, as it is much more comfortable for the stable-

*Three thousand cubic feet of ventilated air-space per horse is
recommended as necessary to preserve his vigor unimpaired, according
to General Fitzwygram. He adds that, since horses are not so sus-

ceptible to draughts and cold as men are, by ample ventilating ar-
rangements this demand for air-space may be considerably decreased.

172 ELEMENTS OF HIPPOLOGY.

men to work in a warm stable, they persuade their employers
that the horses need it, thereby sacrificing the health of their
charges to their own comfort.

Horses that are blanketed in warm stables must, when
they are taken out, be kept moving or warmly clothed. Other-
wise there is, in the winter, grave danger of pneumonia, lung
fever, or other similar diseases, and, in the summer, of founder.

Proper grooming of horses kept blanketed in cold
stables will keep their coats in order. They will be more
willing to work and less liable to suffer from the effects of standing
outside in the cold, when the business or pleasure of their owners
demands it. Veterinary bills will be kept down, and the only
persons to find fault with the arrangement will be the men who
have to tend them.

Insist, therefore, on an ample supply of fresh air in the
stable. Insist also that the fresh air entering the stables does
not produce direct draughts on the horses. The currents of
entering air should be diffused by suitable mechanical arrange-
ments.

In damp, cold climates, valuable horses that justify the
expenditure are benefited by having open fire-places in their
stables to keep them dry and to assist in ventilation. Steam
or hot water heating arrangements should not be used to heat
the stalls.

Dryness should be insisted on in stables.

This can only be secured in most climates by building the
stables in well-drained situations, open to the air and sunlight.

Cleanliness can be secured only by constant super-
vision. 2 ’ i

Cleanliness and dryness go hand in hand. A horse drinks
about eight gallons of water a day. This water is used: first,
to maintain the fluidity of the blood and other liquids, the
moisture of the tissues, and to replace that lost by perspiration;
second, to moisten the food and prepare it for digestion; third,

ELEMENTS OF HIPPOLOGY. 173

acting as a solvent for certain noxious salts, developed in the
nourishment and maintenance of the body, to excrete the
solution as urine.

Much of the daily allowance of water is left on the stable
floor by the horse. If he is well bedded, the bedding absorbs
it. If the floor of his stall is of clay, unless the most perfect
care is taken of it, he will mix clay and urine and manure to-
gether into foul mud, an excellent culture for disease germs and
a still for the manufacture of ammonia. If the floor is of wood,—
a very poor floor, by the way,—the urine soaks into it, and,
unless perfectly drained, renders it very unsanitary. If of brick
or stone, the drainage can be easily maintained if the floor is
well made and the gutters kept open.

In any case, to insure both cleanliness and dryness,
all the bedding must be taken out of the stall in the morn-
ing and the stall cleaned. Such of the bedding as has be-
come urine-soaked must be thrown away with the manure and
the rest exposed to the sun and air and thoroughly dried before
it is put back. The stable should be opened and well aired, the
mangers cleaned, and the dust swept up and carried out.

All persons having animals in their charge should
frequently inspect their stables early in the morning, to
test the quality of the air in them and to see that their
orders respecting ventilation have been carried out. They
should inspect them daily at the hour designated to have the
bedding aired, to see that everything is scrupulously cleaned,
and again when the stables are prepared for the night, to see
that the bedding is clean, dry, and well laid and that the gutters
are not stopped up.

Feeding and Watering.—The time of feeding must be
regulated according to the uses to which the horses are put.
The sequence of feeding should be the same for all horses. As
we have seen, water passes almost directly through the stomach
and small intestines to the czecum, or water-sac; the hay com-

174 HLEMENTS OF HIPPOLOGY.

ponent of the food is largely digested in the intestine, the grain
component, especially oats, is almost entirely digested in the
stomach. Starting with these facts, the order of feeding and
watering is easily formulated. |

A horse does not usually care for water early in the day.
He wants his oats then, and should have them. Oats are con-
centrated food, full of nourishment and energy. They are easily
digested when thoroughly chewed and mixed with saliva. The
average horse should be given for his morning meal at least six
quarts of oats. They should be plump, of sweet, fresh odor,
and free from dust, dirt, or other seeds. After feeding oats, at
least two hours should elapse before giving water. After this
time he should be allowed water at every opportunity until
again fed. If he is worked hard all day, it is best to give him a
second feed of oats at the noon rest-hour, remembering not to
water him for two hours after. When he comes in at night, he
should find his hay ration in his manger and no oats. An hour
afterwards he should be given his grain, and left for the night.
If the stables are inspected at various hours of the night, some
horses will be found lying down, some dozing in a standing po-
sition, some feeding. They like to take their time with their
food. Their stomachs are small. They are slow feeders. Food
assimilates better if taken slowly. They are light sleepers,
easily roused, and they enjoy a nibble of food when awakened.

Often when the stablemen come in, in the morning, in many
of the mangers a portion of the food offered the night before will
be found uneaten, even when no more than the usual amount
had been placed at their disposal. In such cases carefully clean
the mangers and feed-boxes before offering more food. The
horse is off condition and needs coaxing a little. The food he
has been nosing over all night has become stale and unattractive
to him. He will do much better if clean, sweet food is given
him, and he may be induced to eat quite a little if humored
in this way.

ELEMENTS OF HIPPOLOGY. live

Bran should be fed either dry or steamed. A cold
bran-mash is about as indigestible a mess as a horse can be fed.
It is soft and watery and easily swallowed. The molars are
accustomed to hard, dry food. When food is softened it is
ready to swallow, from the horse’s point of view, and down it
goes. A cold bran-mash is usually full of dry, unmoistened
particles; bran does not readily absorb cold water. It is dis-
tinctly a food that needs either cooking or the action of saliva
to prepare it for digestion. If it is put in the stomach cold and
unacted on by saliva, it will ferment and produce indigestion.

If fed dry, it is a food slowly taken into the stomach. It
must be chewed to get it moist enough to be swallowed, and
the only fluids available are secretions of the salivary glands.
When bran, thus moistened, reaches the stomach, it is warm,
digestion has begun, and that process continues naturally.

If fed wet, it should be steamed. A large watertight and
easily cleaned receptacle should be prepared expressly for this
purpose. The bran, mixed with salt in the proportion of one
ounce of salt to three pounds of bran, should be put in it, and
boiling water, in the proportion of two and one-half pints to
three pounds of bran, poured over it. It should then be tightly
covered with woolen blankets, and allowed to steam for fifteen
or twenty minutes. It should be fed hot, and the receptacle it
was cooked in at once cleaned and sunned. After it has been
eaten, the mangers should be cleaned thoroughly. Bran-mash
sours quickly, and, aside from being a good culture for disease
germs, the odor of sour bran is distasteful and makes other food
mixed with it not appetizing.

For horses in good health, bran, preferably dry, should be
fed one day in seven, and in the evening. Cooked mashes are
food for sick or ailing horses.

Horses should have salt, in rock form, in their feed-
boxesatall times. In addition, fine table salt, a heaping table-

175 ELEMENTS OF HIPPOLOGY.

spoonful to each horse, should be fed twice.a week, either mixed
with bran or oats, or placed where they can lick it at their leisure.

The water furnished horses should be pure and fresh,
without taste or smell. In the summer, water should stand
in the trough long enough for the chill to be taken off. Water
in large quantities should never be given horses when they are
heated, unless their exercise is to be continued.*

Conditioning Thin Horses.j-—‘“‘When a horse which is
living under apparently favorable conditions becomes emaci-
ated,—neither from overwork nor from extreme age,—an effort
should be made to discover the cause of the thinness. Begin
by sending for the person responsible for the condition of the
horse and for the farrier, and with their assistance solve the
following points:

1. Has the horse lampas?
Is the tongue sore?
Has he wolf’s teeth?
Are the molars sharp and irregular?
Does he quid his food?

Are the teeth unsound or out of order, or (in the
case of a young horse) are the milk teeth re-
maining in too long, and thereby interfering
with the coming of the permanent teeth?

*Charles B. Michener, V.S. (on p. 35, “‘ Diseases of the Horse,”’
Bureau of Animal Industry, 1903), says: ‘There is a popular fallacy
that if a horse is warm, he should not be allowed to drink; many claim-
ing that the first swallow of water ‘founders’ the animal or produces
colic. This is erroneous. No matter how warm a horse may be, it is
always entirely safe to allow him from six to ten swallows of water.
The danger is not in the first swallow of water, but is due to the ex- .
cessive quantity that the animal will take, when warm, if not re-
strained.’”’ This opinion from such authority is valuable for horsemen
to have, but it is unsafe to permit the average stableman to act on it.
Unless you are sure that your man is careful enough and faithful enough
to stop the horse at six to ten swallows, it is wiser to adhere to the
rule that the hot horse should have no water until cooled.

{From Captain M. F. Rimington’s (British Army) little hand-
book, “ Hints on Stable Management,” pp. 30, 31.

7. Does he bolt his oats?

8. Does the adjacent horse steal his oats, or bully
him?

9. Is he a spare* horse?

10. Does he suffer from parasitic worms?

11. Is his urine normal?

12. Is his liver out of order? (This is indicated by
the yellow and bloodless appearance of the
gums.)

13. Is he watered regularly?

‘Tf it is still impossible to account for the horse being out of
condition, you should next endeavor to find out if he really
gets his oats or only a small proportion of them; in a word, if the
oats are being systematically stolen. Assured that the oats are
not tampered with, it becomes necessary to make further in-
quiries as to the habits of the horse, as to whether he is restless,
or in the habit of fretting or over-exciting himself, either in the
stable or when at work. In some cases it is impossible to dis-
cover the cause or causes at work. In obscure cases, a complete
change of diet, and, as far as possible, of surroundings, often has
a wonderful influence. For example, a couple of months’ run
at grass in the spring or summer is most beneficial to thin, hide-
bound horses. Failing this, it will often be found useful to fill
the manger at each stable hour with chaff; this will give the
horse something to pick at, and keep him from fretting. Some —
men get horses into condition more easily than others, and it will
often be found that a thin horse, put into good hands, will
improve rapidly.”

Grooming is another important item in the care of the
horse. Much of the excretion is done through the skin. While
at work a horse perspires freely, and the very nature of his work
keeps him constantly, while at work, in a dusty atmosphere.

178 ELEMENTS OF HIPPOLOGY.

The dust and sweat and precipitated salts of perspiration com-
bine to form a cake at the hair-roots that clogs the pores. Dry-
ing, it has an unpleasant astringent feeling that annoys the an-
imal. This crust of filth and dirt catches and fosters disease
germs and parasites that feed upon the animal and that are
never found on well-groomed horses.

Besides cleaning the coat, grooming stimulates the
circulation and acts as a tonic to the horse. lt rests a tired
animal, relieves congestion following a hearty meal by diverting
part of the excessive blood-supply from the digestive region.
Twenty minutes’ brisk grooming in the morning and twenty-five
in the evening is the right amount to keep the animal’s coat -
clean and skin healthy. More time than that will be appre-
ciated in the satiny coat of the horse. A horse can hardly be
groomed too much. The average horse likes to be fussed with
and handled. He enjoys having his legs rubbed and his coat
brushed. The currycomb is not so much enjoyed. It should be
used merely to loosen caked mud or manure on the exterior of
the coat, and, except with the greatest care, never below the
knees or hocks. Use only the fingers and brush on the mane
and tail. Throw cards and mane-combs out of the stable.

In grooming with the horse-brush, the groom should stand
well away from the horse, legs well apart, and, with the brush
in the hand next the horse’s head (and the currycomb in the
other), brush the coat with the lay of the hairs, throwing as
much of the weight of the body into the brush as possible.
After three or four strokes with the brush, clean it on the comb.
Clean the comb every few minutes by tapping it on the ground
in rear of the horse.

The sheath should be frequently washed with Castile
soap and water, and never oiled. Oil simply collects and
holds dust and makes washing more often necessary. The

- glands of the skin secrete all the oil needed to keep it in condition.

ELEMENTS OF HIPPOLOGY. 179

Keep the long hairs of the muzzle cut short. They
have no useful function in the domestic horse and are unsightly.

Keep the fetlock short the year around. In winter it
should be an inch and a half long and neatly trimmed. In°*
summer it should be clipped.

This principle in the care and treatment of horses
cannot be too closely adhered to: Give your horse plenty
of good food and pure water, house him in a dry, clean,
and well-ventilated stable, and he will keep surprisingly
well. Have him well shod. Work him hard, through
long hours, and he will still keep well under the above
conditions. When he does get sick or injured, go fora
good veterinarian, follow his advice to the letter, and so
save your money and your horse.

The following rules laid down in the Cavalry Drill
Regulations are so good that they are reproduced here.
Every person having to do with horses should observe
them strictly:

Never threaten, strike, or abuse a horse.

Before going into a stall, speak to a horse gently and
then go in quietly.

Never take a rapid gait until a horse has been warmed

up by gentle exercise.
_ Never put up a horse brought in a heated condition
to the stable or picket-line, but throw a blanket over him ~
and rub his legs and walk him until cool. When he is
wet, put him under shelter and wisp him until dry.

Never feed grain to a horse nor allow him to-stand
uncovered when overheated. Hay will not hurt a horse,
no matter how warm he may be.
| Never water a horse when heated, unless the exercise
or march is to be immediately resumed.

Never throw water over any part of a horse when
heated.

180 HLEMENTS. OF HIPPOLOGY.

Never allow a horse’s back to be cooled suddenly by
washing or even by removing the blanket unnecessarily.

To cool the back gradually, the blanket may be re-
moved and replaced with the dry side next the horse.

There is no emergency that will justify striking the
horse on the head.

CHAPTER: XVI.

ENDURANCE OF HORSES.—VICES.—PUNISHMENT.

The endurance of a horse is the measure of his ability to
resist fatigue and is dependent directly upon his powers of di-
gestion and assimilation and the co-ordination of his nervous
and muscular systems.

Muscular power is derived from the contraction of the
muscles. The muscles of locomotion are composed of numerous
fibers, built up in groups, and attached by a tendon at each end
toa bone. One of these bones serves as a fulcrum, the other as
a lever. The muscle lies between them. Each of the fibers of
the muscle, animated separately by a nerve, contracts, and tho
whole muscle is shortened. The bones, when a flexor muscle is
contracted, are brought nearer together; they are separated more
when acted on by extensors. The muscular action is the same
in all muscles—the fibers contract in the direction of their length.

As a muscle contracts its chemical nature changes. It con-
sumes oxygen and certain other elements brought toit by the
blood, which come to an active muscle in increased quantities,
and it gives off carbonic acid and numerous other waste products
that the blood washes off through the veins.

The entire operation, the impulse given by the nerve, the
contraction of the muscle, and subsequent chemical change in
the constituent elements of the blood ‘‘feeding’’ the muscle,
the pull on the tendon, and the resultant energy transmitted to
the bone, must work in perfect harmony with the corresponding
actions of all the muscles involved, and is consummated in an
almost inappreciable period of time.

The muscles of locomotion are all voluntary muscles; all
are controlled by the volition of the animal. The muscles that

182 KLWMuNTS OF HIPPOLOGY.

control the organs of respiration, digestion, and circulation are,
almost entirely, involuntary, but their actions are under control
of nerve impulses, coming, as a rule, from nerve-centers other
than the brain. No muscle contracts unless a nerve animates it,
and there must be a nerve impulse for every contraction.

‘‘Prolonged exercise is always accompanied by an expend-
iture of food, of blood, and of nerve-tissue, by an increased cir-
culation, by an acceleration of respiration, and, finally, by a
ereater activity’’* of the organs of excretion. Admitting this, it
is plain that the tired horse owes his condition indirectly to one
of two causes: either to nervous exhaustion, or to an excessive
clogging of the muscles with waste tissues. In either case, rest
and food are the only restoratives.

The ordinary gasoline motor illustrates the situation ex-
actly. A drop of gasoline is exploded by an electric spark in a
cylinder. The resultant gases, by their expansion, move a piston
that is geared to the wheels, producing locomotion. As long as
the supply of gasoline is kept up, the electric batteries remain
‘‘alive,”’ and the spent gases can escape and not clog the cyl-
inders, the efficiency of the machine is unimpaired. But let
any one of these conditions lapse and the machine stops. So
with the horse. As long as the digestive apparatus enriches the —
blood, the lungs oxidize it, the veins carry away the waste
tissues, the skin, lungs, kidneys, and other organs of excretion
remove the débris from the system, and the vigor of the nervous
system (the horse’s electric battery) is unimpaired, so long will
the horse do his work. The failure of any one of these functions
and the limit of his endurance is reached. He may stumble
along a little longer, but it is with apparent labor and to little
purpose. He needs rest...

From the exterior of the horse a great deal can be predicted
of his powers of endurance. The competent horseman can tell
exactly to what sort of work he is best suited—whether he is a

*“ The Exterior of the Horse,’ Goubaux and Barriere, p. 415.

ELEMENTS OF HAIPPOLOGY. 183

draft-horse, a driver, a saddler, or a general utility horse—but
no one can tell which of two horses, externally of equal promise,
will be able to do the most work.*

This is especially true of horses bred for speed. If two
colts, of similar breeding, are given advantage of the most
scientific care and training, are brought up by the same trainer,
on the same diet, and with exactly similar treatment, it is usually
impossible to tell, until the actual test on the track is made,
which will prove the speedier.

The horse doing slow work contracts his muscles slowly;
the expenditure of tissue is very moderate, and especially mod-
erate is the expenditure of nerve-tissue. He is tired after a long
day’s work, but it is the weariness that comes from the exhaus-
tion of the food-supply, not from nervous exhaustion. The cir-
culation, in the ordinarily healthy animal, is quite sufficient to
keep the blood pure and the muscles cleared of débris. In fact,
much of the food-supply is stored between the muscles and in
the abdominal region in the form of fat. This fat is easily drawn
on to restore waste tissues in emergencies when extra work is to
be done, or when the food-supply is diminished. It also adds to
the mass of the horse, and so increases his value for draft pur-
poses. The nerves of such an animal are never over-taxed. He
is kind, gentle, free from vice, and obedient.

The race-horse, the trotting-horse, the hunter, the polo-
pony—‘‘the horse of luxury’’ generally—has work of an en-
tirely different sort to do. Speed is what he is bred for; speed
and endurance. The race-horse is bred in economic idleness.
He is trained to make his machinery perfect and under perfect
control. The preparation for a race, after his schooling is done,

*Of a team of large sorrel horses of no particular breed, owned

used up three team-mates, and is still sound and in prime condition.

qualities. He does his full share of the work, yet what he thrives
under wears out other horses, apparently just as good, in a short time.

184. HLEMENTS OF HIPPOLOGY.

is a matter of weeks, and his work is done in.two or three minutes.
Yet, with all the preparation possible, after this short period of
work, he is more exhausted than is the draft-horse after ten
hours’ steady pulling. To restore him to his full strength, he
must be cooled slowly, fed and watered with judgment, exercised
regularly.

The nervous strain in this sort of work is tremendous. The
muscular contractions are frequent, violent, and sudden. The
supply of blood and the change in the muscular tissues are
greatly increased and the débris correspondingly increased.
The lungs are called on to purify the blood in greater quantities.
The nostrils are dilated and the windpipe straightened to in-
crease the volume of air entering the lungs. The inspiration of
all this added work must come from the nervous system, from
the brain and other nerve-centers. These organs must be finely
developed to do this extra work properly. The result is that
the race-horse, as a rule—and in less degree the same is true of
the other horses of luxury—is an excitable animal, nervous, high
strung, often vicious. He has little of the docility and tracta-
bility of the farm-horse.
~'s The polo-pony is called on to play two periods of fifteen
minutes each two or three times a week during the polo season; .
yet in these few minutes of play he earns his oats as honestly as
the cab-horse does in his ten hours a day.

The horse should never be pushed to the limit of his en-
durance. It is not necessary to do this to determine when he
has worked enough. The horse’s breathing furnishes an ex-
cellent witness to his condition. While he is working easily, he
breathes without effort. When he begins to tire, his breathing
becomes more and more labored, and his heaving flanks will
show the effort he is making to keep up. If the horse is not
rested then and allowed to recuperate, other unmistakable signs
of exhaustion will follow.

ELEMENTS OF HIPPOLOGY. 185

“As to nerve -conductibility, its feebleness or its disap-
pearance is seen in unequivocal signs on the locomotory ap-
paratus; the muscular contractions are weaker and slower; the
efforts diminish in intensity and rapidity; the intervals be-
tween the steps are no longer equal and in co-ordination; the
members meet and strike each other; the gait, at first uncertain,
becomes tottering; the head hangs low; the subject becomes
more and more insensible to the surroundings; soon he falls in a
heap and dies at his task. But, before reaching this point, his
steps are less free, heavy, and uncertain; he forges. All these
signs should be sufficient, and their appearance demands an
immediate cessation of the experiment.’’*

VICES AND DANGEROUS HABITS OF THE HORSE.}

“The horse is an animal of a noble and generous disposi-
tion, and naturally possessed of few vices, although he is occa-
sionally met with having a bad and even furious temper, and, as
may be expected, manifests great variety of natural habit. His
vices, however, are too often attributable to the effects of im-
proper training and to tricks which he is taught by the treatment
and folly of his groom or keeper.

‘““The first breaking-in of the horse should only be intrusted
to persons of mild disposition, as it is by kind and patient treat-
ment alone that we can hope to succeed in rendering this val-
uable animal truly useful and docile. No doubt but in nine
cases out of ten, where horses exhibit furious or stubborn tempers,
that these have been produced from the cruelty and ignorance
of their first trainers.

‘“Restiveness.—The most unpleasant and dangerous of all
vices possessed by the horse is that of restiveness. Sometimes

this proceeds from a naturally bad temper and at other times
from faultiness in education. This term includes plunging,
rearing, kicking, bolting, and general impatience while mounting.
A horse with any of the above faults can never be depended upon,
for, although we may use means to counteract a particular vice,
whether by compulsion or gentle measures, he may exhibit that
vice when we are off our guard and are least expecting it. Force
may bring him to obedience, and he may succumb to him who
has had the determination to subjugate him, but, when mounted
by another, he is extremely liable to break out again. A horse
that kicks in harness may be driven with safety by a cautious
or experienced driver or coachman, but still there is no cer-
tainty of his not exhibiting the same trick years afterwards;
indeed, most horses which have been kickers return to it again.

‘“‘However high the temper which the horse may exhibit,
we would recommend that he should be broken from his vices by
kind and soothing means and these exercised with patience for a
considerable length of time, and force should only be resorted to
when all other means have failed.

‘‘There is little chance of reclaiming a bad-tempered horse
by harsh treatment; indeed, it will always be found to have an
opposite tendency. An ill-tempered groom should never be al-
lowed to enter a stable, however fit he may be for his business in
every other respect; for a surly, bullying fellow is sure to frighten
horses so much that when he enters a stable they will jump from
side to side at his approach. Many a scar has been inflicted by
such a man by using his pitchfork instead of soothing the animal
for his fault, and if asked how the horse came by the blemish, he
invents a falsehood to account for it.

‘‘Rearing.—Rearing is one of the worse vices ina horse,
and is practiced with the intent to throw the rider off. Some-
times it is the result of playfulness, but even then it is a dangerous
and unpleasant fault. The use of a deep curb and sharp bit will,
in some instances, cause even a quiet horse to rear, and when

ELEMENTS Of HIPPOLOGY. 187

this is the case, immediate recourse must be had tothe snaffle
bridle.

““As in kicking, however, this is seldom or never cured.
Horse-breakers have attempted it by absurd and dangerous means
—namely, that of pulling the horse backward on a piece of soft
eround. This has ruined many horses. If rearing proceeds
from determinedly vicious habits, it is a hopeless case, as the
animal seldom abandons it. Sometimes horses rear from play-
fulness, which is, however, very different from that which pro-
ceeds from passion.

“Kicking.—The vice of kicking is too often caused by
horses being teased, tickled, and pinched by grooms from wanton
mischief or thoughtless folly. The habit becomes habitual with
the animals, and what was at first only done in play is exercised
in anger, and often too when one leasts expects it. In short, it
is a dangerous and incurable vice.

“Horses with an irritable or fidgety disposition kick the
stall or bail, and especially during the night. This is a great an-
noyance to other horses in the stable and breaks their rest. Be-
sides, the animal is liable to injure himself seriously, and bring
on swelled hocks or other malady. Mares are more given to
this than horses; and in either it is difficult to eradicate if once
confirmed. 3

“The vice is seldom eradicated. Never trust a kicker.

“Biting.—This trick often proceeds from play, and is
taught by the folly of grooms or stable-boys teasing the animais.
But what they have acquired as a sport becomes a fixed habit;
and when thwarted in any manner they will sometimes bite
with great severity. Like other vices, this is difficult .of cure.
and it is but seldom they can be really broken of it. Teasing a
horse should be strictly forbidden. Biting, like other vices,
should never be taught the animal, as it is easier to avoid it
than to effect a cure. Gentle treatment is the best suited for all

188 HLEMENTS OF HIPPOLOGY.

our domestic animals and the surest way. to command ther
affections.

“Seizing the Cheek of the Bit.—Some horses are so cun-
ning as to get the cheek of the bit into their mouth, which gives
them a great command over their rider or driver. There is no
cure for this; and the only thing that can be done is to fasten a
piece of round leather, or use some other mechanical contrivance,
so that the animal cannot possibly get the cheek of the bit into
his mouth. Neither soothing nor beating will remedy this trick,
as the horse who has once been guilty of it is sure to seize the
first opportunity to repeat it when anything vexes him. Many
very serious accidents have happened to persons from horses
running away with the cheek-bit between their teeth.

“Running Away.—The only thing that can be done in
this case is to use a strong curb with a sharp bit, and at the
same time always keeping a firm bridle-hand.

‘“‘Shying.—Of all the vices incidental to the horse, shying
is one of the worst, and more accidents have happened from it
than any other of the vices or defects of the horse. Shying pro-
ceeds from various causes, but one of the principal is defective
vision; timidity stands next; and it often proceeds from a dis-
position to be playful. This vice is far less common among
high-bred horses than with those which are half-bred, although
we have met with it in some of our first racers.

‘“When we have a horse given to shying, our first attention
should be directed to the cause—that is, whether it proceeds
from friskiness, timidity, or defective vision.

‘‘When shying proceeds from playfulness, it is difficult to
judge what mode of cure is best to be adopted, because if cor-
rected for it, he will associate with any object that diverts his
attention the infliction of punishment, which will tempt him to .
run away under the dread of a flogging; and if caressed for the
fault, it is liable to induce him to repeat it. But, of two evils,
gentle correction must be adopted, and rather to pass by the

ELEMENTS OF HUIPPOLOGY. 189

object than to take him up to it. He should also be spoken to
sharply.

“Tf shying proceeds from fear of new objects, the true way
to correct him of this is not to force him up to them, but to pat
him and to soothe him, but avoid beating him; and take care
to pass the objects of his fear again and again, always going
nearer to them every time you pass. This will familiarize him
to them. Seeing that these are harmless, he will soon learn to
pass by unnoticed any novel object which he may meet with
upon a road.

“When an animal is given to shying from defective sight,
the only method to effect a cure is to take him up to it, and, in
the act of doing so, he must be coaxed to approach it, and on no
-account must he be beaten; and, although it sometimes happens
that the horse will manifest great reluctance to do s>, he «ould
be persevered with and not allowed to proceed until he has been
closely the object of his fear. After he has been a few times thus
treated, he will soon learn to pass with indifference any object
which he may meet.

‘“‘Restiveness, and Resisting Being Mounted.—Some
horses which possess a lively or impatient temper manifest a
desire to start off before the rider can get seated in the saddle.
Indeed, some will attempt to set off whenever the foot is put in
the stirrup. This is a troublesome and dangerous fault, even
with the most expert horsemen, and especially so to those who-
are inexperienced or infirm. Horses sometimes become so cun-
ning that they know a good from a bad horseman, and finding
they are either to be or actually mounted by a timid or indif-
ferent rider, will endeavor to throw him off, or bolt away before
he is properly seated.

_ “When a horse has this propensity, he should be mounted
quickly and without fear, and not allowed to proceed on his
journey until he is perfectly quiet. Instances are not 1ew where
horses that are generally pleasant and easy to mount become

190 ELEMENTS OF HIPPOLOGY.

restive when too high fed and having too little work. The
remedy for this is obvious.

“Vicious W hile Cleaning.—Very oreat differences exist in
the temper exhibited by horses under the operation of cleaning.
Some that are steady and quiet on the road and in the field
cannot be cleaned without great hazard to their grooms as well
as the danger of laming themselves. This often proceeds from
a very sensitive skin and at other times from their grooms having
inflicted severe chastisement on some former occasion when
cleaning. Besides, ill-disposed grooms, by teasing the animals,
or currying them with a broken-toothed comb or uneven-surfaced -
brush, teach them this bad habit,.and have even a delight in
seeing the animals show their teeth; and this is continued until
it becomes a fixed vice. If a change of grooms takes place, what
was done partly in play is then manifested in anger, and serious
injuries have been inflicted upon the unsuspecting stranger. It
therefore behooves grooms to be cautious how they handle a
strange horse.

‘There is much variety in the sensibility of the skin of
horses, some being so tender that moderate rubbing gives them
uneasiness, while others are so much the reverse that the whip
hardly excites it. It will not be difficult to overcome this vicious
habit. When the groom discovers it, the best plan is to use a
gentle hand while cleaning, and lean lightly on those parts which
seem most sensitive; and avoid punishing the horses for exhib-
iting restiveness, and he will soon lose all recollection of the
former ill-treatment which he had received from his groom, and
become quiet and steady.

‘“‘Crib-Biting.—Crib-biting is one of the worst habits which
a horse can acquire, and is seldom or ever cured. The horse
seizes the manger with his teeth while he stretches his neck for-
ward, and after some spasmodic action of the throat, a islight
grunting sound is uttered, which appears to be accompanied by a
drawing in of air. The cause of this trick is not yet well under-

ELEMENTS OF HIPPOLOGY. 191

stood; and whether it proceeds from a bad habit, or a defect in
the false palate and back part of the mouth, still remains un-
discovered, and therefore we shall not indulge in any speculative
opinions as to its origin.

“One serious effect of this trick is the wearing down of the
teeth; and instances have occurred where they have been
broken. It has likewise been found that crib-biters are more
liable to colic than those without this vice.

“Tt has been found that crib-biting is acquired by horses
being in the stable with one which has the trick. Among the
expedients which have been resorted to for the cure of crib-
biting, the edge of the manger has been lined with iron, also with
sheepskin besmeared with aloes, tar, and other disagreeable sub-
stances, but all with no effect. The only thing in this case is to
resort to a preventative, and that will be found in the use of a
strap buckled tightly around the neck, which has the effect of
compressing the windpipe and rendering it impossible to resort
to it; but no sooner is the strap removed than the horse re-
commences his old habit, so that it must be constantly worn to
be of use. But the continued use of it is apt to produce irrita-
tion in the trachea, and this will terminate in the affection termed
roaring. A five or six months’ run in a field has been tried
without proving a remedy. Crib-biters are generally in low
condition.

““A muzzle barred across the bottom will prevent crib-
biting. This must be made only of sufficient width to allow
full action to the lips, so that the animal may pull his hay from
the rack and eat his corn, but so close as not to admit of him
grasping the edge of the manger. Crib-biting is legally con-
sidered an unsoundness.

“Wind-Sucking.—This is so intimately connected with
erib-biting that it may properly be considered a modification of
it, as it is accompanied by a want of condition and the same
bending of the neck, with the head drawn inward, is manifested,

192 ELEMENTS OF HIPPOLOGY.

and the horse alternately opens and closes his lips, and a sound
is produced similar to sucking air. The remedies attempted
have been tying up the head of the horse, except when feeding,
and the application of a muzzle with sharp spikes bending to-
wards the neck, which will prick him when drawing in his head.

“Not Lying down.—Horses are sometimes prone to stand-
ing constantly, and some only lie down once in a fortnight, or
even a longer period. When this is the ease, they are generally
liable to swellings in the limbs, and seldom able to go through
much work. Such horses should, if possible, be put in a stable
by themselves and left at liberty, and a well-made bed will
sometimes tempt them to lie down. No means can be adopted
to force the animal to take rest by lying down. When it is not
possible to place him in a stable alone, an empty box should be
constructed, so that he may be left for the night unhaltered in it.

‘““Pawing.—This is a disagreeable and very bad habit, and
proceeds from an irritable temper. Bruised feet and sprained
legs too often proceed from it. The shoes are quickly worn
down in front, and the litter considerably wasted.

“Weaving.—Animals of an impatient, irritable temper,
that dislike confinement in a stable. will sometimes keep moving
their head, neck, and body to and fro, like the motion of a
weaver’s shuttle. These have been called ‘weavers.’ Such
horses seldom or never carry much flesh, from their fretful
temper and incessant movement. The only preventative is to
tie the head close up, except when feeding.” :

REWARD AND PUNISH MENT.

In training and handling a horse, full advantage should be
taken of his lack of intelligence and his acute memory. .To make
a, horse understand in his training that he is wanted to back, for
instance, the rider must, in the first place, adopt a set of signals
that mechanically suggest the idea of backing. The horse is

ELEMENTS OF HIPPOLOGY. 193

standing quietly. The rider’s legs are closed, lower legs slightly
in rear, to induce the horse to draw his legs under him. The
knees are not closed, unless he wavers to the right or left. The
hand is lowered and the rein drawn in. He arches his neck,
bringing the mass of his head and neck nearer to his body. At
the same time the rider leans back. The shifting of the mass of
the horse and rider to the rear throws the center of gravity to
the rear. The horse has “‘drawn his legs under him’’ at the
suggestion of his rider’s heels, his balance is insecure in conse-
quence, and he steps back. He has done what the rider wishes
and, at the instant of yielding, the rider should encourage him
with hand and voice. The second time the request is made of
the horse by the same signals he steps back more readily, and
should instantly be rewarded. Finally, after repeated trials, the
horse learns that, when both of the rider’s legs are brought back
with equal pressure, and he is reined straight back, he is ex-
pected to back, because he remembers that when he did re-
spond in that manner to those signals he was rewarded.

Horses do not recognize persons; they do remember re-
wards and punishment. The author has often noticed, in the
riding-hall at West Point, where the same horse does duty for
two cadets on alternate days, that certain horses, as the platoon
is marched into the hall, appear to be looking for someone.
The cadet to whom the horse is assigned approaches him, and
the horse makes every sign of recognition, and is rewarded with
an apple or a bit of sugar. It seems almost unquestionable that
he has recognized an old friend. The next day the other cadet
to whom he is assigned approaches him; the horse gives the same
signs of looking for someone, then of recognition, and then of
disappointment. The second cadet is not his friend of the apple
or sugar; it was not the friend, after all, that he was seeking,
but the dainty that the friend was bringing.

It is well for horse-users that horses are indifferent to the
identity of the persons handling them, otherwise they might ob-

194 ELEMENTS OF HIPPOLOGY.

ject to a change of riders. The greater the intelligence of a
horse, the more care must be shown in his training and use. A
dull horse becomes sluggish under abuse; an intelligent one
becomes vicious.

The tone of voice used by a rider has great influence on a
horse, if not used at inappropriate times. It is of no use to be
constantly talking to a horse, but a word spoken in a sharp,
high tone will startle him, while one in a softer, lower tone will
soothe and steady him. Like all other aids in horsemanship,
the voice should be used consistently and at the critical moment.

The whole education of the horse is based on the principles
of reward and punishment. No animal is more sensitive to ap-
probation than a normal horse. Observe a young horse, that has
not been spoiled in training, when he is learning a new lesson.
The attitude of his head and ears, the expression of his eye, show
that he is watching the aids closely. After successfully ex-
ecuting a command of his rider, if the latter pats his neck and
speaks kindly to him—‘‘makes much of him’’—he shows his ap-
preciation of the attention by his expression. The rider should
be careful to give the neck a good, generous slap—not enough
to hurt, but sufficient to attract his attention, and positive
enough to show no timorousness. Horses quickly learn whether
or not their riders are timid, and are very quick to take ad-
vantage of the occasion and follow their own inclination. It
often seems as if an old troop-horse enjoys the fears of the re-
cruit. This is also shown in the horses used for the instruction
of the cadets of the third class at the Military Academy. Usually
only the quietest, steadiest horses are chosen for this work.
Some of them plod stoically around the hall, impervious to any-
thing the cadet can do. Others take liberties with their riders,
in an apparent spirit of play, that they would never think of
showing if the rider were a first-class man. For this reason the
pat on the neck should be positive, reassuring the horse that the

ELEMENTS OF HIPPOLOGY. 195

rider knows what he is about and appreciates the work of his
horse. It should be accompanied by the voice.

There is only one instant when punishment should be ad-
ministered to a horse—that is the instant the fault was com-
mitted, and punishment should never be given in anger. The
horse does not reason; he feels and he remembers. The horse
cannot understand why he is punished. What he knows is that
certain acts of his are met with reward, certain others with pun-
ishment, and, if properly handled, .he will do the things he was
doing when he was rewarded and avoid the things he was doing
when he was punished. For this reason, when a horse rears, he
should be struck with the whip while he is in the air, not after
he comes down. If he kicks, he should be struck while actually
kicking. If struck after the kick is finished, he will be very apt
to kick again. The cause and the effect must come together.

James Fillis, probably the greatest high-school rider of all
time, says:* ‘‘The great art in breaking is to reward and punish
in an appropriate manner; in order to do which we must seize
the exact moment of obedience or resistance. Here we must
bear in mind the fundamental principle of breaking—namely,
that reward should follow obedience as quickly as punishment
follows disobedience.”’

Sons, 1902), p. 112. foot-note.

CHAPTER X VIL

THE CARE OF SICK HORSES.

The prescriptions and methods of treatment contained in
this chapter are given by Farrier Edmund Lee, U.S. M. A. De-
tachment of Cavalry, who, for more than twenty years, has had
the care of the sick horses in the stable of that detachment.
Probably nowhere in the service are horses put to severer tests
than here. The stable where he has done his work was over-
crowded, damp, dark, and badly ventilated. The horses’ work
is of the most trying character—part of the year it is violently
severe, at other times there is nothing at all for half of them
to do. Ina word, the horses were badly stabled and irregularly
worked. As a result, there was much sickness, especially of
the lungs and digestive apparatus. The veterinarian visited the
stable every third day and prescribed treatment for the horses
on sick-list at the time of his visit. All emergency cases and
all the nursing fell on Farrier Lee. In the midst of all these
difficulties he has faithfully nursed and “‘doctored’’ the sick and
the cripples and has prolonged their usefulness as no veter-
inarian could have done without an equally faithful nurse.

These prescriptions are simple, and, as far as drugs can be,
safe. They have the merit of having been tested by many years
of successful use.

In these prescriptions a teaspoon is one fluid-dram; a table-
spoon, half a fluid-ounce. Medicines should always be weighed
or measured as accurately as circumstances will permit.

The troubles most commonly met with in a cavalry stable
are sprains, open sores, cuts, thrush, scratches, sore backs, colic,
and colds. Polo-ponies are laid up more often with sprains,
sore backs, bruises, and ringbones than by any other cause.

ELEMENTS OF HIPPOLOGY. 197

For sprains, a lotion made of four tablespoons of lead
acetate and four tablespoons of tincture of opium, mixed with
one quart of water is very soothing. This is a stronger lotion
than the usual white lotion, which has but two tablespoons of
each drug. Opium is a sedative and acts to relieve pain; lead
acetate is astringent and tends to contract the capillaries and to
cool the part by limiting the supply of blood to it.

This lotion is applied by soaking absorbent cotton with it
and fastening it to the part with a loose bandage. The bandage
is kept wet by pouring the lotion on several times daily. This
lotion is better for sprained tendons and ligaments than for
sprained muscles. For the latter, and for sore throats as well,
a very efficient stimulating liniment is made of a pint of linseed
or olive oil, four tablespoons each of water of ammonia, tur-
pentine, and opium. This is to be thoroughly mixed and ap-
plied by hand-rubbing; never internally.

The oil is slow to evaporate, penetrating, and carries the
other drugs with it into the affected tissues. The water of am-
monia and turpentine stimulate a more active circulation, and
the opium allays the pain.

For cuts and open sores, use an olntment composed of a
heaping tablespoon of oxide of zinc, rubbed up with one-fourth
of a teaspoon of glycerine, four tablespoons of vaseline, and
thirty drops of carbolic acid. The zinc oxide can also be dusted
dry on the wound. The wound should be first well washed
and dried.

Oxide of zine is an antiseptic—that is, it destroys the germs
of disease, putrefaction, or fermentation. It is obnoxious to
flies. Carbolic acid is also an antiseptic; the glycerine and vasel-
ine are added to blend the two into a smooth ointment. A cut
or an open sore that is not infected needs only to be kept quiet
and clean to heal. The principal object of this ointment is to
keep disease germs from the cut and to keep it from drying by

198 ELEMENTS OF HIPPOLOGY.

too rapid evaporation. The latter is accomplished by the vasel-
ine, which evaporates very slowly. ;

In the treatment of open sores or cuts, every effort should
be made to ‘prevent infection and the consequent suppuration.
It may be safely asserted that suppuration in an open wound or
sore is always the result of neglect. Abscesses and internal
ulcers become infected by germs brought to them, usually by
the blood itself. A severe bruise, for instance, may develop
into an infected sore without any noticeable external sign of its
presence, but a cut can always be seen, and, if the antiseptics
and suitable bandages are at hand, it should not be allowed to
fester. An excellent antiseptic wash is made of one part of car-
bolic acid to twenty parts of water. This will smart when ap-
plied. The addition of one part of glycerine will allay the
smarting to a certain extent, without destroying the germ-
destroying properties of the carbolic acid. :

Thrush is a direct result, usually, of bad stable manage-
“ment, but as it does not cause lameness or become prominently
noticeable until it is in quite an advanced stage, it is frequently

found in old, poorly-drained stables with bad floors, in spite of
careful attention to the horse’s feet.

A horse affected with thrush should be taken to the black-
‘smith’s shop, where all the ragged and diseased portions of the
‘frog should be cut away. The frog should then be cleaned thor-
‘oughly and sprayed with equal parts of carbolic acid and water—

a very radical treatment, but one that Farrier Lee swears by.
The frog is then dusted with powdered bluestone and packed
with pine tar and oakum. A leather sole is then laid on and
held in place by the shoe. This treatment will be of no avail
unless the unsanitary cause of the disease is removed; it will
‘stay its progress, but it will not cure it.

Another very good treatment for thrush is to apply a powder
composed of equal parts of sulphate of zine, bluestone, and sul-
phate of iron. The zine sulphate is an astringent and it also

ELEMENTS OF HIPPOLOGY. 199

destroys the diseased tissues; the bluestone has much the same
caustic effect and it is also a tonic. This powder is dusted on
the frog, which is then packed with oakum, held in place with a
bandage, a leather boot, or a leather sole put on under the shoe.

For sore backs, use the familiar ‘white lotion’’—four
tablespoons each of sulphate of zinc and carbolic acid in one
quart of water. The carbolic acid is of more value if the skin
is chafed than when it is unbroken. Its virtue lies principally
in its germ-destroying power. This lotion is rubbed by hand
on the saddle-gall, if the skin is not broken, and applied to an
open sore with a sponge.

If the sore back degenerates into a sitfast, the indurated,
scabby portion should be cut out by a veterinarian, and the
wound of operation then treated like an ordinary wound.

Care should be taken that sore backs and sitfasts are not
chafed; no treatment will cure them as long as the conditions
causing them continue to exist.

Colic is often caused in horses that are exhausted by per-
mitting them to drink too freely of cold water. This is a spas-
modic colic, very painful, and a sedative and stimulant is needed.
Two tablespoons of cannabis Indica (Indian hemp), five drops of
morphine, thirty drops of tincture of capsicum, mixed with a
pint of water and given at one dose, will usually give relief; if
not, repeat the dose in about an hour.

The cannabis Indica soothes the nerves and so lessens the
spasms of the muscles, whose actions are governed by the nerves.
Morphine is a sedative, and the capsicum is a stimulant to restore
the circulation in the walls of the stomach.

Colic caused by indigestion—flatulent colic—is treated with
four tablespoons of aromatic spirits of ammonia, two tablespoons
of sweet spirits of nitre, mixed in a pint of water and given in
one dose. Repeat in an hour, if necessary.

Aromatic spirits of ammonia is useful to expel gas from the
stomach and intestines; it is also a safe stimulant. Nitre is also

200 ELEMENTS OF HIPPOLOGY.

a stimulant that acts on the kidneys; it neutralizes irritating
acids. Its frequent use is very debilitating and injurious to
the kidneys.

For obstruction colic, four tablespoons of oil of turpen-
tine in a pint of raw linseed oil, given at one dose, will usually
expel the obstruction.

It should not be very difficult to distinguish between the
three kinds of colic mentioned above. The stablemen will know
if the horse. has drunk too much cold water. The presence Of
fresh dung in the stall will argue against obstruction colic, and
if the distress is not caused by cold water, the assumption in
this case would be that the horse was suffering from colic re-
sulting from indigestion.

For coughs, a useful mixture is made of two tablespoons
of oil of tar, two tablespoons of glycerine, and two tablespoons
of chloroform, mixed in one pint of raw linseed oil. Two table-
spoons given two or three times a day is the dose.

For coughs and colds, nursing will do more than drugs.
The patient should be kept warm—with blankets in the winter—
dry and away from draughts. He should have hay in small
quantities and frequently changed, for the discharge from his
nose will soil it if left before him long. He should have hot
steamed bran-mashes and have constant access to water. The
disease will then run its course, in the usual case, in a few days.
Exercise should be avoided. His nostrils and lips should be
frequently washed.

Scratches, whose seat is in the back of the pastern, is a
disease that is brought about by the same conditions that pro-
duce chapped hands in human beings. The part affected should
be carefully washed and dried and kept greased with an ointment
made of one part of oxide of zinc to ten parts of cosmoline, vas-
eline, or lanolin. This dressing should be changed frequently,
by thoroughly cleansing the part and re-applying the ointment.
The horse can be used, in mild cases, during the treatment.
Severer cases demand rest as a part of the treatment, because
bending the pastern keeps the cracks open.

ELEMENTS OF HIPPOLOGY. 201

CHAPTER XVIII:

PREVENTABLE DISEASES.

Preventable diseases are those that result from improper
care or use. A large proportion of the diseases that a horse is
liable to comes under this head.

They may be grouped in two general classes: diseases due to
bad shoeing, and diseases due to bad stable management.

Under the first head come, more especially, diseases in the
feet and legs, manifested by lameness.

Bad shoeing is the commonest cause of all varieties of dis-
eases of this region. If, in fitting the shoe, the wall is not rasped
down evenly all around, if the shoe is too small for the foot, and
the crust is rasped off to cover up the defect, if the bars are cut
away, if the shoe is too high behind so that the frog cannot
strike the ground, the result will be felt in the horse’s action.

The following diseases are usually caused by improper
shoeing, or may be prevented by proper shoeing: speedy cut,
splints, strained tendons, broken knees, ringbones, sidebones,
treads, brushing, corns, and cracks.

When a horse is laid up for any reason, his shoes should
be removed at once. This permits a freer growth of the horn,
it gives the frog a chance to get a bearing, and it is a rest to the
foot. The plantar surface of the foot should be rasped smooth
and the edges rounded off whenever the shoe is taken off, to
prevent the wall from splitting. ,

There is no better way to build up a horse or to keep
one in health than to allow him an occasional run at
grass. A horse that is a bit run down in-flesh will be much
benefited by having his shoes taken off and allowed to run for
a few days in a pasture. The natural ‘exercise, the green food,

202 ELEMENTS OF HIPPOLOGY.

and the freedom will combine to produce most beneficial re-
sults. Every horse should be turned out in an enclosure of
some sort every day, if only for an hour or two, whenever pos-
sible. Horses brought in hot from work and turned loose will
cool out slowly with no damage to themselves. They will take
enough exercise to keep from getting chilled.

Pasturing is especially good for diseases of the tendons,
ligaments, and bones, and of the breathing apparatus. A horse
with a docked tail should not be turned out to grass or in a
paddock during fly-time; he must be given his exercise in an-
other way. He will be so tormented by the flies that no benefit
will result from his freedom.

The condition of a horse—that is, its state of being gen-
erally—is the result of stable management. In a good stable,
where clean stalls are the rule, where.good forage is fed, where
the water is pure, where the horses are thoroughly groomed,
and which is kept dry and fully ventilated, where the doors are
wide and high, and all the stable fittings are arranged so that
there are no projections to injure the horses, there will be need
of the veterinary surgeon but rarely.

A horse is said to be in good condition when he is in vig-
orous health and strength, and in hard condition when, by
proper care and exercise, he is in shape to make his supreme
effort, as should be the case before a race.

Exercise is just as necessary to the well-being of a
horse as to man. Every horse that is kept in a stable should
be exercised at least two hours a day to keep him well. Lack of
exercise will weaken a horse as much as overwork. The amount
of work expected of a horse should depend upon his condition,
and this depends as much upon the exercise he has been getting
as upon his diet or sanitary surroundings. A horse that has
been turned out to pasture will take enough exercise to keep
well, but will not keep in working condition. So a horse that
has been convalescing on grass, after a month or two, may seem

_ ELEMENTS OF AIPPOLOGY. 203

to be in fine condition, but, if put to work, will be found to sweat
freely after slight exertion and to tire easily. His condition
should be hardened by gradual work or exercise.

Neglect of sanitary care of the feet, by allowing the horse
to stand in manure, or in urine-soaked mud, will bring on thrush,
scratches, and other diseases of the soft tissues of the feet.

Neglect of grooming is responsible for loss of condition,
thus making the horse liable to disease. Much of the excretion
‘of waste tissues is done through the pores. If this way of ex-
cretion is closed because of the clogging of the pores, the waste
tissues will accumulate near the surface, impeding the flow of
blood in the capillaries, the hair will appear lusterless and dead,
through being badly nourished, the dead cells of the skin will fill
the coat. The horse will appear listless and irritable. His vi-
tality will be low and he will be ready to receive and foster the
germs of disease. If he is thoroughly groomed, the circulation
_-will be stimulated instead of retarded, excretion will go on prop-
erly, and the coat will show its healthy condition and that of
the skin beneath by its smooth luster. Grooming does not ben-
efit the coat by smoothing it, but by cleaning the skin. The
smoothing of the coat is the merest incidental.

Bad forage is: responsible for diseases of respiration and
digestion. Dusty hay is hay that has not been properly cured
and that breaks up into minute dust-like particles. These par-
ticles are sharp and irritating to the mucous membrane of the
lungs, and render it liable to disease. Musty or sour hay, grain,
or bran produce indigestion and, ultimately, colic.

Reference has been made to the order of watering and
feeding. First ‘water, then hay, then grain,—no water for at
least two hours after grain. A horse that has been all day at
work comes in at night ravenously hungry. If he finds his oats
in the manger, he will rush at them, bolting them without chewing
them. With their hard husk, which is mostly cellulose, un-
broken, they pass through the stomach undigested, to lie in the

204 ELEMENTS OF HIPPOLOGY.

intestines ready to ferment and cause intestinal disorders. If
he is fed his hay first, he will, of necessity, eat it slowly. When,
an hour or so later, his grain is given him, the edge of his hunger
is broken, and he will be hours at his oats; they will be perfectly
digested and will do him a maximum of good.

Dampness and lack of ventilation in stables predis-
poses the horses to diseases of respiration and to rheum-
atism. These conditions, also, by lowering the vitality of
horses, make them fit subjects for other diseases, especially
those of germ origin.

Every stable should be provided with ample openings for
the admission of air and for the escape of foul air. The fresh-air
openings should be low down and so arranged that no current of
air blows directly on the horses. The escape of the foul air
should be arranged for at the highest part of the stable, and
should be so made that rain or snow cannot enter the stable.

Carelessness in the arrangement of stables is account- |
able for many injuries from which horses should be immune.
Low, narrow doors account for poll-evil and broken hips. Boards
splintered by kicks or gnawed through leave rough ends to
scratch and blemish horses. Swing-bars whose chains are
patched with baled-hay wire, and prominent hooks, nails, or
latches where horses might strike themselves, may inflict wounds
that are trifling enough in themselves, but when located about
the knees or hocks reduce materially the value of a a on
account of the suspicions aroused by their sears.

Bad saddling and badly-fitting bridles put horses out
of business by causing saddle-galls and sore mouths, that Just a
little care would effectively prevent.

Contagious diseases are frequently allowed to spread,
more through ignorance and carelessness than for any other
reason. A horse with any discharge from his nose, however
slight, should be isolated at once. He should not be turned
loose with other horses, or watered where they are watered, or

HLHMENTS OF HIPPOLOGY. 205

have his equipment mixed with theirs. His stall should be dis-
infected, and his equipment sterilized after his recovery.

Skin diseases, such as mange, ringworm, scratches, grease,
and those scurfy diseases at the bend of the hock and knee,
known as sallenders and mallenders, and the presence of vermin
in a horse’s coat, are the surest indices of bad stable management.

As a general rule, a horse of good conformation that is
properly fed and watered, thoroughly groomed and stabled in a
sanitary manner, will keep well. Hard work, unless pushed to
an unreasonable degree, will fatigue a horse, will at times greatly
exhaust him, but, unless his condition has been lowered by some
preventable cause, no permanent injury will result.

The horse is made for fast or hard work. He is admirably
fashioned for it, but the natural laws of his existence must be
obeyed or he will break down before his time, not from over-
work, but from neglect.

206 ELEMENTS OF HIPPOLOGY.

CAP PIR OGLXe,

IRREGULARITIES OF ACTION.

Irregularities of action result from disease or defects of
conformation. A well-put-up horse that is sound follows the
usual law of movement.

The natural gaits—modes of progression—of the horse are
the walk, trot, and gallop. Some horses have a fourth gait,
the amble—pacing—but it is usually an acquired gait. These
gaits a horse assumes, when free to follow his own inclination,
without any training or preparation.

The walk is a square gait, where each foot is planted in
succession. The body is supported all the time.

The trot is a diagonal gait; the feet are planted in pairs:
right fore and left hind, left fore and right hind. In changing
support from one diagonal to another there is a slight period of
suspension, when the body is wholly unsupported. Aside from
this brief instant, the body is supported alternately by one di-
agonal pair or the other, and never by more than two feet.

In the gallop the feet are planted in succession. One fore
foot is constantly leading—that ‘is, planted in front ot the other,
and the leading fore foot bears the weight of the body for a
longer time than any other. The body is advanced by a series
of leaps and is much of the time in suspension.

In all of these gaits the feet should move in parallel
planes, should be planted squarely, and should not strike
each other.

In the walk there should be no halt in the stride. The
beats caused by the planting of the feet should be regular and
followed by the same intervals.

HLEMENTS OF HIPPOLOGY. 207

In the trot each diagonal pair of legs should sustain the
weight of the body for the same length of time.

In the gallop the horse should lead with equal freedom with
each fore foot; his feet should be well bunched during the leap,
and well extended in receiving the weight of the body and in
throwing it forward. The canter differs from the gallop very
little; it is the slow gallop. The leap is shorter, the leading foot

Figure 102.— ‘Iowa.”’

is not advanced so far. The body is in suspension for a shorter
time. The merging of the canter into the gallop is impercep-
tible. When a horse changes from the walk to the trot and from
the trot to the canter, the rider is conscious of the instant the
change is made, but as the gait increases to the gallop and the
racing gallop, or run, he is conscious merely of an increased
speed, not of a change in the arrangement of footfalls.

208 ELEMENTS OF HIPPOLOGY.

There are two artificial modifications of the pace: the rack,
where the hind foot foots it ahead of its leading fore foot; and
the single foot, where each foot foots it independently of the
others. The single foot is a very easy gait indeed for the rider.

The trot has also two artificial modifications: the fox trot,
when the fore foot foots it ahead of its diagonal hind foot; and -
the running walk, where the hind foot foots it ahead of its
diagonal fore foot.

The Kentucky saddle-horse has all of these gaits and the
walk, trot, amble, and gallop as well. The Kentucky breeder
resents having the gaits above described styled artificial, because
he has bred his strain of horses to possess them naturally. They
are so termed because a horse must either be bred or trained
te possess them.*

Lameness may be defined as an-alteration of action
adopted by an animal in an effort to avoid pain. Most
sound horses comply with the rules for the natural gaits given
above. Their heads are carried uniformly, without nodding.
If a horse is seen to dwell longer on one leg or pair of legs
than another, if he nods his head at each step, if he shortens
his gallop, or is stiff in his action, it is because there is pain’
in one of his legs and he is trying to keep his weight off it or
to keep from straightening it. He is lame.

The trot is the best gait in which to locate lameness. The
walk is too slow; three legs are always on the ground in that
gait, and, unless very lame indeed, it will be difficult to locate
it at a walk. The gallop is too complex and too rapid a gait
for this purpose. The trot, on the contrary, is simple and easily
analyzed. It is not too rapid for careful observation. One hind
foot and the diagonally opposite fore foot bear the whole weight
of the body at any instant.

*See Captain Hayes, ‘‘Points of the Horse,’’ and Gouboux and

Barriere, ‘‘Exterior of the Horse,’ for complete discussions of the
subject of gaits.

ELEMENTS OF HIPPOLOGY. 209

In trying a horse for lameness, he is trotted on hard,
smooth ground. If, in trotting, the weight is held on one diag-
onal pair longer than on the other, it is because bearing the
weight on the latter pair is painful, and the horse transfers it as
quickly as possible to the sound pair. The lameness is thus
located in one of the two legs.

The front legs, in addition to bearing their share of the
weight of the body, must support, unaided, the weight of the
head. When a horse raises his head, he shortens the lever-arm,
the neck, and thus throws the center of gravity of his body
further back. This relieves the forelegs of part of their load
and puts it on the hind legs. By lowering the head the lever-
arm is lengthened, the center of gravity comes forward, and the
front legs relieve the hind ones of part of their burden. So,
having located the lameness in one pair of legs, if, when that
pair is supporting the body, the head is down, the lameness is
behind; if the head is up, the lameness is in front.

If he is lame in both hind or both front legs, he will travel
in a stilty, stiff manner, and will, when lame in front, keep his
head higher, and when lame behind, lower, than is his natural
poise when at rest. |

A horse usually turns on his front feet. If he is quickly
turned and is noticed to dwell more on one foot than on another,
it is an indication of unsoundness in the favored foot. This test
will sometimes assist in locating obscure cases of lameness
in front.

If, after noticing these irregularities of action on hard
ground, the horse is trotted on soft ground, and he travels true,
the suspicion that he is unsound, and lame in consequence, is
confirmed. If, on the contrary, he has the same peculiarity of
gait, the irregularity is probably due to his conformation or to
some habit.

Unsoundness in front may sometimes not be detected in

the horse’s action, when his attitude while at rest will give a
; ——lo——

210 ELEMENTS OF HIPPOLOGY.

sure indication of it. A horse that is sound always stands with
his front feet equally advanced. By a provision of Nature, the
weight-bearing muscles of his front legs are so arranged that
when he stands square in front they are at rest. This is not so
behind. ‘There he is constantly shifting his burden; one leg
supports it while the other rests.

Figure 103.—Porntine A Tox.

If a horse is observed while standing to advance one front
foot, or draw it back, resting it on toe or heel, pointing it, as it
is called, he is unsound. If he rests the foot on the toe, it is to
relieve ‘pain at the heel, to straighten out the flexing ligaments,
and the inference is that he has navicular disease (Figure 103).

ELEMENTS OF HIPPOLOGY. 211

If he rests the foot on the heel, it is to relieve pressure at the toe,
or the lamine, and the inference is that he is foundered, or,
more rarely, that the extensor tendons are pressing on a bony
tumor, and he has ringbone.

Frequently a horse stands level in the stall and goes lame
in front on hard ground. This is never the case in diseases of
the soft tissues, but is caused by incipient bone disease.

If a horse is lame behind and the location of the dis-
ease is not apparent, the services of a skilled veterinarian
should be called in. It is difficult enough to properly
diagnose lameness in front; he is skilled indeed whocan
do so behind.

The general rule, that obscure lameness behind is in
the hock, and in front in the foot, or in the ligaments and
tendons, is a safe one for the amateur to follow.

Many horses, through lack of symmetry, have peculiar
faults of action not properly called lameness, though resembling
it. They can be usually corrected ie proper shoeing or by the
use of boots or straps.

JUDGING HORSES AND THE EXAMINATION
FOR SOUNDNESS.

In the pages that precede an effort has been made to indi-
cate the general conformation of well-built horses, and those
diseases and defects to which they are most liable. The appli-
cation of the theory of what suitable conformation and sound-
ness are will come when the student is called on to purchase
a horse for himself.

The general public is suspicious of horse-dealers, more be-
cause of its ignorance of the physical and civil laws that relate
to the soundness of horses than for any other reason. For that
reason a brief investigation into the subject will spare the
purchaser much annoyance and mortification.

The law of warranty has been briefly stated in the opening
chapter, page 19. Reference to that will convince the reader
that the examination of the horse he is going to buy and his trial
had best be very thorough and complete, as it will prove a very
difficult matter to establish the existence of any unsoundness
or defect prior to the date of purchase, in a legal manner, to the
satisfaction of a court.

A purchaser must not expect to find many perfect horses;
there are few such, and, excepting young horses, the very fact
of their being without blemishes argues that they possess some
undesirable quality that has limited their use, and that will
probably always limit it. He can, however, learn to recognize
those glaring defects that make horses especially undesirable to
own, and to discriminate between them and lesser defects that
can can be. overcome, or that will not uncigtelie with the use to which
the horse i is to be put.

It is a surprising fact that most purchasers want to buy a
fat horse. This is a failing that, to be successful, dealers must
meet by fattening their horses into what is called selling condi-
tion. Horses in this fat, smooth condition cannot be put to
hard work at once; they are more subject to inflammatory dis-
eases than when properly hardened to their work, and, more
than all, the fat covers up defects of conformation that would
be apparent in working condition.

It is always best to see the horse you are thinking of buying
in his own stall, when he has not been prepared for your visit.
You can then inspect him for such stable vices as cribbing,
- weaving, or kicking. 3

Cribbing is an injurious habit of seizing with the teeth the
manger, halter-strap, or woodwork of the stall, or any similar

214 ELEMENTS OF HIPPOLOGY.

A Stupy IN CONFORMATION.

thing within his reach, and, at the same time, drawing in his
breath with a peculiar noise, known as wind-sucking. It is
usually a sign of digestive derangement. A crib-biter can al-
ways be detected by an examination of his incisors. The an-
terior portion of the tables is worn down much more than the
posterior. This is one of the few vices horses have that is taught
others by example.

Weaving is a stable vice manifested by swinging from side
to side in the stall. It is rarely more serious than an indica-
tion of a nervous, restless nature. It is a frequent accom-
paniment of crib-biting.

Kicking is such a serious vice, and so difficult to eradicate,
that no horse should be knowingly purchased that possesses it.
It is often shown by the appearance of the woodwork of the

ELEMENTS OF HIPPOLOGY. 215

stalls near the heel-posts. A horse given to kicking in the stable
usually shows scarred heels and capped hocks.

It should also be noticed whether he points a toe in the
stall. The meaning of this symptom has been sufficiently
explained.

The inspection in the stall finished, have the horse brought
into the light; if his general appearance is satisfactory, and
he seems suitable for the purpose to which it is proposed to
put him, his age should be verified, and his sight tested in a
general way. |

Assuring yourself in these three regards, apparent general
suitability, age, and vision, the more critical examination is
begun. A note-book and a pencil should be at hand to take
down such departures from normal conditions as you may notice.

First notice color, sex, and peculiar markings, so as to be
able to identify the horse later on. Then proceed to a more
critical examination of the eyes.

The best light is that coming directly from above, from a
skylight or a high window in an otherwise darkened room. If
such a place is not available, bring him to the stable door, closing
all apertures behind him. After placing him directly facing the
source of light, stand behind his shoulder and look through each
eye, from side to side, with great care, noting everything, no
matter how slight, that interferes with their perfect transpar-
ency. A horse that has any disease, or any mark of disease, in
the eye, no matter how slight, is not a sound horse. After the
examination of the anterior portion of each eye, from behind,
stand in front of him and compare closely both eyes, to see if
there is perfect clearness in each, that the pupils are of equal
size, and that they dilate and contract equally. If any sus-
_ picions are aroused, no matter how slight, of the presence of
cataract, the candle-test should be applied.

legs are of the greatest importance for saddle-horses. Pass

the hand along the withers and the shoulder for saddle-galls,
sitfasts, and collar-galls, and over the elbow for shoe boils.

The knees should be most carefully inspected for broken
knees. While no serious injury may have resulted to the horse’s
knees by his falling on them, while the joint may be perfectly
unimpaired, still the fact that the horse has fallen on his knees

at some time in his history should cause the careful purchaser to—
end his examination with the discovery of scars of broken knees.

The nerves of the feet are possessed of marvelous sensitive-
ness, considering their horny covering, and an animal whose
shoulder is sloping enough to plant his foot well out in front of
him will not fall, unless he is tired out from extraordinary ex-

ELEMENTS OF HIPPOLOGY. 217

ertions, or unless he is seriously unsound in one or both of his
front legs. Whatever the cause of the broken knees, reject
the horse.

If the knees are sound, look at the head of the cannon-bone,
on the inside, for scars of speedy cut. This, as we have seen, is
a defect of action caused by bad conformation. It is a fault
difficult to eradicate. The blow is so painful as to frequently
bring the horse to his knees. It is liable to recur at any time,
and, as the blow is given only when the horse is going at top
speed, the accident resulting from his fall is sure to be a serious
one. For this reason, unless the horse is wanted for slow work
only, reject him when he shows a scar of speedy cut.

Splints are found between the knee and fetlock, on or near
the splint-bones. They are recognized as small bony knots,
easily felt. If they lie forward on the cannon-bone and not -
near the knee, they usually are harmless. If they are on the
back of the cannon-bone, they may interfere with the action of
the tendons. To test this, apply pressure to the tendons. If
the horse shows pain by flinching, and the tendons show inflam-
mation, reject him. A pegged splint is almost sure to cause
permanent lameness.

Passing the hand down the back tendons, compress them
steadily. Any tenderness or signs of inflammation is cause
of rejection.

Carefully inspect the fetlock, pastern, and ankle for wind-
galls, ringbones, sidebones, and grease, and the coronet for
treads and quittor.

Inspect the pastern and ankle for scars of firing or neu-
rotomy. Be very suspicious of any scars in this region. A
horse that has been nerved has but a brief period of usefulness
ahead of him. ;

Pick up the foot and examine the sole for contracted heels,
thrush, canker, and corns. See that the sole is concave, and

that there is no irregularity in the shoe. Feel the coronet, walls,
and heels for fever, or any other indications of laminitis.

Tap the front of the foot with a knife or a coin for seedy toe,
and look carefully for false quarter. Inspect closely the surface
of the walls for signs of rasping out founder rings. If this has
been done, unless the foot has been most carefully stained, the
hoof will show varying colorings. Be especially careful in your
scrutiny of a hoof that has been stained or polished.

Inspect his nostrils for discharges of any character.. A horse
that has a nasal discharge is unsound, and the inspection should
be put off for a few days to determine whether the discharge is
or is not chronic. The nasal membranes should be moist, pale
in color when the horse is quiet, and bright red after sharp ex-
ercise. They should be free from scars.

The ears should be free from'warts, and easily handled. Do
not expect a horse to permit his ears to be pulled about willingly,
but he should allow them to be handled enough to be bridled
easily and to have them trimmed and cleaned.

The poll should be inspected for fistula.

_A good horse that has been well broken and kindly handled
will not dodge or show the whites of his eyes when handled about
the head. Such actions are the surest witnesses to abuse during
his bringing up.

Pass then to the off side, examining the jugular vein on each
side for signs of blood-letting (to relieve congestion of the brain—
blind staggers). Examine the withers and back from that side.
Go over the right front leg with the same care and in the same
manner that you used in the examination of the left one.

220 ELEMENTS OF HIPPOLOGY.

Examine the back, especially the lumbar region, for evi-
dences of kidney trouble. Examine the hip, croup, and stifle.

from in front of the leg. If there is a protuberance on the lower
edge of the hock-joint, inspect if with care for marks of blistering
or firing. Feel it; if it is hard, it is probably a spavin, and the
horse should not be bought. Look for bog-spavin, and thor-
oughpin, capped hocks, and curb.

Blistering is the process of producing artificial inflammation,
by the application of a powerful liniment, to relieve congestion
or to hasten bone-deposit.

ELEMENTS OF HIPPOLOGY. 221

Firing produces the same result, in a more radical way, by
actually burning the part with a hot iron.

Blistering, if severe, leaves an irregular scar, partly de-
nuded of hair. Rows of dots or thin parallel lines are the marks
of firing.

If there is any suspicion of spavin, a simple test is to pick
up the leg, bend it well, and hold it up for a minute or two; then
drop it, and start the horse off at a trot. If sound, he will
not limp.

The cannon-bone should be examined for splints, rare as
they are behind, and the tendons examined for evidence of in-
flamed or sprained tendons. The same critical examination
should b2 made of the feet as was made infront, and of the left
hind leg as was made of the right.

Examine the tail; see that the quarters are well filled up
behind, and that all is in order under the dock.

Examine the sheath; look under the belly to see that there
are no warts or protuberances there, and that the belly is free
from sears. Look on all the legs for wire cuts.

The horse’s action should next be tested. Have him led at
a slow gait away from you, noticing the action of the hocks,
pasterns, and feet. Look closely for any dwelling on either
hind leg, indicating lameness in the other. Watch his head, to
see if he nods excessively.

When he turns, note carefully the ease of action in the front
legs, and, as he approaches, note the way he handles his front
feet, and the carriage of his head. He should be trotted past
the inspector two or three hundred feet, again turned and brought
to a standstill near him.

ELEMENTS OF HIPPOLOGY. 223

Avoid horses with hackney knee-action. They are almost
sure to go wrong in front while young, and, while stylish, are
expensive and not apt to be long serviceable.

Notice his breathing, the expansion of his nostrils, the heave
of his sides.

Have him mounted next, and galloped sharply for a quarter
of a mile or so, and again inspect his breathing. If he labors
noiselessly for breath (thick wind),.if the period of exhalation is
longer than the period of inhalation (heaves), if he makes a
noise at both inhalation and exhalation (whistling), or dure
inhalation only (roaring), reject him.

Feel his pulse; the most convenient place is at the jaw. A
large artery runs around the lower border of the jaw-bone and
up on the outside immediately in front of the heavy muscles of
the cheek. It can be easiest felt where it curves cround the
jaw-bone, by pressing it gently against the bone. To t:ke the
pulse, press the balls of the first and second fingers against the
artery. The count should be from 33 to 40 beats a minute;
nearer the first number before exercise, and the latter just after.
The pulse slows down in old age. It should be strong and reg-
ular. The heart can be easily heard by placing the ear at the
base of the throat or on the ribs behind the shoulder.
| An inspector who buys horses under contract should demand

that they come up to the specifications of the contract. Con-
tractors are presumed to have read the specifications before
they make their bids. The latter should be based on the value
of the horses asked for, and nothing short of that should be
expected. When horses of the grade advertised for are worth
$175, a contractor who agrees to furnish them for $150 should
not be permitted to put in inferior stock because of his false bid.
Not only does the inspector bring himself into disrepute for ac-
cepting inferior animals, but honest bidders who are ready to
deliver horses up to standard, at a proper price, are cut out of
their right to do so. |

224 HLEMENTS OF HIPPOLOGY.

The whole theory of advertising for purchase by contract is
based on the idea that bidders can learn what is wanted ex-
actly, and can then figure at what price they can afford to make
the deliveries. If this theory is perverted by permitting con-
tractors who have made dishonest or haphazard bids to evade
their contracts by furnishing as good horses as the price they
offer would warrant, it would be better to abandon it altogether. |

Well-bred horses that may be predicted as capable of giving
good service have about the following conformation:

Head small, clear-cut, and well set on a long, slender neck.

Shoulders sloping well forward, muscular, and long.

Front leg well muscled above the knee, cannon shorter than
leg-bone, and both upright and straight, ankle sloping forward,
long and elastic; fetlock, ankle, and pastern, smooth, firm, and
small.

Feet small, sound, and with well-developed frogs.

Barrel deep, long, and well-ribbed up, about equal in size at
girth and middle, and sloping gradually from the middle towards
the sheath.

Withers reasonably prominent and well muscled.

Back flat, well muscled, and free from saddle-marks.

Coupling short and strong.

Croup slightly convex, viewed from side and rear. There
should be considerable length from loin to tail, and not much
curvature.

Tail well set on, and, when the animal is in motion, carried
away from the body. The hair should be fine and silky.

Thighs prominent and muscular and well filled up, when
viewed from behind. Measured from hip to hock, the thigh
should be long.

Hocks clean-cut, not puffy, wide from the side, large and
well bent. The point of the hock should not be noticeably
prominent. Both hocks, viewed from behind, should be parallel
and straight under the horse’s body.

The cannon-bone should be flat and broad. Pasterns and
feet as in front legs.
