The round and compact bodies of Morgan horses enabled them to "get the best of their feed" and made them suitable to perform a wide variety of tasks. Their large eyes, small ears, and short, broad heads set on gracefully curved necks carried high provided them with a proud countenance. Also blessed with ground-covering gaits, the Morgans were able to cover many miles day after day at steady rate of speed. This ability, combined with a businesslike attitude to get the job done, made them a favorite horse of all work. (In later years, when a taller horse became the vogue, the Morgans would be criticized for their relatively short stature.)

Sherman Morgan, Bulrush Morgan, and Woodbury Morgan were Figure's most famous and influential sons. These stallions, along with other unrecorded offspring, came to dominate the horse industry of New England and northern New York. In the 1820's they were favorite teams for the stage lines and for fieldwork on farms and transport to town. Their reputation as "horses of all work" was becoming widespread.

Black Hawk, a son of Sherman Morgan; and Hale's Green Mountain Morgan, a grandson of Woodbury Morgan, were the dominate Morgan sires of the mid-19th century. Green Mountain Morgan had a host of admirers gained, in part, from his appearance as a parade horse at militia training. He was also renowned for his resemblance to Figure. Black Hawk was famed for his speed and elegant style and he, in turn, sired the world champion trotter Ethan Allen. In the 1850's these two rival stallions were shown at Midwestern state fairs with great success and heightened the continuing demand for Morgan horses.

New England supplied big city markets such as New York with Morgan horses for public transportation and freighting as well as private driving. Morgan horses comprised the preferred teams of stage line owner M. O. Walker of Chicago. They were taken to California to be employed as ranch and harness racing horses. In other areas of the West they were also used as ranch horses.

During the Civil War Morgans were dependable cavalry mounts and artillery horses. Again, their easy-keeping qualities and ability to endure grueling condition allowed them to outlast other types of horses. Several units of cavalry in the Union army and one (known) of the Confederate army were mounted on Morgan horses. United States General Philip Sheridan's famed charger Winchester (a.k.a. Rienzi), who was immortalized after the war, was a descendant of Black Hawk.

Due to a trend in which taller horses were becoming more desirable with great speed at short distances, the popularity of Morgan horses began a decline, which would not reverse itself for several years. Morgan mares continued to be widely used by horse breeders, but were bred to taller stallions of non-Morgan breeding. The purpose was to capture the enduring qualities of the Morgan but with increased size in the offspring. The result was a more marketable product for farmers selling to the city markets. As a result of this practice the Morgan, as it had been known earlier in the 19th century, almost disappeared.

From this type of foundation other American horse breeds were developed. Harness racing had become an exceedingly popular sport for which the Standardbred was developed. Other major American breeds that contain the Morgan horse in their initial development include the American Saddle Horse, Tennessee Walking Horse, American Quarter Horse, and American Albino.

Continuing modernization and development of new technologies, however, were affecting the horse market nationwide. Electrification of trolleys and continuing expansion of trains reduced the demand for harness horses significantly. Larger farms and a corresponding increase in the size of agricultural machinery to do the work were creating a demand for larger, heavier draft horses.

The 1890's witnessed efforts on the part of many to locate and "regenerate" the Morgan horse. A business horse or roadster was desired with not only speed but with the classiness which would reflect upon one's social standing as well. Writers berated the disappearance of the "ancient" type Morgan and called for its regeneration, if it could be found. Pockets of these Morgans had survived, particularly in northeastern Vermont, though much reduced in number.

Many new breeding programs were established. Edwin Hoffman of Lyndon, Vermont became a Morgan horse dealer and assisted many nationwide with locating and purchasing Morgans for their farms. It was at this time the foundation was laid for the highly influential Brunk bloodlines. The National Morgan Horse Breeders Association was formed during the 1893 Colombian Exposition (although it was not destined to last). Joseph Battell published his 1,000 page Morgan Horse Register in 1894.

The Vermont State Fair of the 1850's and 1860's had been a popular venue for the showing of Morgan horses. This fair was discontinued in the 1890's when as economic downturn forced it to cease operating. It was revived in 1907 and, within a very few short years, became the national showcase of the Morgan horses. In 1909 the Morgan Horse Club was formed during the fair. Morgan horses from as far as Illinois and Pennsylvania came to participate in a highly competitive atmosphere.

It was here that the first endurance rides were held. The Morgan Horse Club created a challenge to prove that the Morgan was the best horse for cavalry purposes. These rides were eventually held at various locations around the United States and were extended to 300 miles in length. These rides were the forerunners of today's competitive trail and endurance rides.

By an act of Congress in 1905, a farm to perpetuate the Morgan horse was established. The United States Morgan Horse Farm was established in Weybridge, Vermont, on Joseph Battell's former Bread Loaf Stock Farm. The farm was operated under the auspices of the federal government until 1951, when it was transferred to the University of Vermont, which continues managing the farm today.

Again, modern technology interfered, with the advent of the automobile effectively reducing the need for horses. After this time, the primary focus of the horse market would become recreational. With exceptions, of course -- horses used for ranch work and, until the tractor became economically viable, for draft work on farms. In many rural areas horses continued to be a major source of transportation to market, church, and school. Although the need was diminishing, the Army sought remounts for its cavalry with demand peaking during World War I.

Throughout the balance of the 20th century the Morgan horse, like other types and breeds of horses, has been used primarily for recreational purposes. The majority of Morgan horse owners use their Morgans for pleasure. Many also compete with their Morgan horses in a wide variety of sporting events. Morgans are highly competitive in driving competition as well as in horse shows and on trail rides. They are competing in reining, cutting, and dressage with success.

The difference between a horse and pony is not simply a height difference, but also a difference in phenotype or appearance.There are noticeable differences in conformation and temperament. Ponies often exhibit thicker manes, tails and overall coat. They also have proportionally shorter legs, wider barrels, heavier bone, shorter and thicker necks, and short heads with broad foreheads. They often have calmer temperaments than horses and also a high level of equine intelligence that may or may not be used to cooperate with human handlers.

Light riding horses such as Arabians, Morgans, or Quarter Horses usually range in height from 14.0 (142 cm) to 16.0 hands (163 cm) and can weigh from 386 kilograms to about 540 kg (850 to 1200 lb). Larger riding horses such as Thoroughbreds, American Saddlebreds or Warmbloods usually start at about 15.2 hands (157 cm) and often are as tall as 17 hands (172 cm), weighing from 500 kg to 680 kg (1100 lb to 1500 lb). Heavy or draft horses such as the Clydesdale, Belgian, Percheron, and Shire are usually at least 16.0 (163 cm) to 18.0 hands (183 cm) high and can weigh from about 680 kg up to about 900 kg (1500 lb to 2000 lb). Ponies cannot be taller than 14.2h (147 cm), but can be much smaller, down to the Shetland pony at around 10 hands (102 cm),[7] and the Falabella which can be the size of a medium-sized dog. However, while many miniature horse breeds are small as or smaller than a shetland pony, because they are bred to have a horse phenotype (appearance), their breeders and registries classify them as very small horses rather than ponies. The largest horse in history was a Shire horse named Sampson, later renamed Mammoth, foaled in 1846 in Bedfordshire, England. He stood 21.2½ hands high (i.e. 7 ft 2½ in or 2.20 m ), and his peak weight was estimated at over 3,300 lb (approx 1.5 tonnes). The current record holder for the world's smallest horse is Thumbelina, a fully mature miniature horse affected by dwarfism. She is 17 inches tall and weighs 60 pounds.

Pregnancy lasts for approximately 335-340 days and usually results in one foal (male: colt, female: filly). Twins are rare. Colts are usually carried 2-7 days longer than fillies. Females 4 years and over are called mares and males are stallions. A castrated male is a gelding. Horses, particularly colts, may sometimes be physically capable of reproduction at approximately 18 months but in practice are rarely allowed to breed until a minimum age of 3 years, especially females. Horses four years old are considered mature, though the skeleton usually finishes developing at the age of six, and the precise time of completion of development also depends on the horse's size (therefore a connection to breed exists), gender, and the quality of care provided by its owner. Also, if the horse is larger, its bones are larger; therefore, not only do the bones take longer to actually form bone tissue (bones are made of cartilage in earlier stages of bone formation), but the epiphyseal plates (plates that fuse a bone into one piece by connecting the bone shaft to the bone ends) are also larger and take longer to convert from cartilage to bone as well. These plates convert after the other parts of the bones do but are crucial to development.

Depending on maturity, breed and the tasks expected, young horses are usually put under saddle and trained to be ridden between the ages of two and four. Although Thoroughbred and American Quarter Horse race horses are put on the track at as young as two years old in some countries (notably the United States), horses specifically bred for sports such as show jumping and dressage are generally not entered into top-level competition until a minimum age of four years old, because their bones and muscles are not solidly developed, nor is their advanced training complete. For endurance riding competition, horses may not compete until they are a full 60 calendar months (5 years) old.

Horses have, on average, a skeleton of 205 bones. A significant difference in the bones contained in the horse skeleton, as compared to that of a human, is the lack of a collarbone--their front limb system is attached to the spinal column by a powerful set of muscles, tendons and ligaments that attach the shoulder blade to the torso. The horse's legs and hooves are also unique, interesting structures. Their leg bones are proportioned differently from those of a human. For example, the body part that is called a horse's "knee" is actually the carpal bones that correspond to the human wrist. Similarly, the hock, contains the bones equivalent to those in the human ankle and heel. The lower leg bones of a horse correspond to the bones of the human hand or foot, and the fetlock (incorrectly called the "ankle") is actually the proximal sesamoid bones between the cannon bones (a single equivalent to the human metacarpal or metatarsal bones) and the proximal phalanges, located where one finds the "knuckles" of a human. A horse also has no muscles in its legs below the knees and hocks, only skin and hair, bone, tendons, ligaments, cartilage, and the assorted specialized tissues that make up the hoof (see section hooves, below).

A horse is a herbivore with a digestive system adapted to a forage diet of grasses and other plant material, consumed regularly throughout the day, and so they have a relatively small stomach but very long intestines to facilitate a steady flow of nutrients. A 1000 pound horse will eat between 15 and 25 pounds (approximately 7-11 kg) of food per day and, under normal use, drink 10 to 12 gallons (about 38-45 litres) of water. Horses are not ruminants, so they have only one stomach, like humans, but unlike humans, they can also digest cellulose from grasses due to the presence of a "hind gut" called the cecum, or "water gut," that food goes through before reaching the large intestine. Unlike humans, horses cannot vomit, so digestion problems can quickly spell trouble, with colic a leading cause of death.

Horses are adapted to grazing. In an adult horse, there are 12 incisors (six upper and six lower), adapted to biting off the grass or other vegetation, at the front of the mouth. There are 24 teeth adapted for chewing, the premolars and molars, at the back of the mouth. Stallions and geldings have four additional teeth just behind the incisors, a type of canine teeth that are called "tushes." Some horses, both male and female, will also develop one to four very small vestigial teeth in front of the molars, known as "wolf" teeth, which are generally removed because they can interfere with the bit.

There is an empty interdental space between the incisors and the molars where the bit rests directly on the bars (gums) of the horse's mouth when the horse is bridled.

The incisors show a distinct wear and growth pattern as the horse ages, as well as change in the angle at which the chewing surfaces meet. The teeth continue to erupt throughout life as they are worn down by grazing, and while the diet and veterinary care of the horse can affect the rate of tooth wear, a very rough estimate of the age of a horse can be made by looking at its teeth.

The critical importance of the feet and legs is summed up by the traditional adage, "no foot, no horse." The horse hoof begins with the distal phalanges, the equivalent of the human fingertip or tip of the toe, surrounded by cartilage and other specialized, blood-rich soft tissues such as the laminae, with the exterior hoof wall and horn of the sole made essentially of the same material as a human fingernail. The end result is that a horse, weighing on average 1,000 pounds, travels on the same bones as a human on tiptoe. For the protection of the hoof under certain conditions, some horses have horseshoes placed on their feet by a professional farrier. The hoof continually grows, just like a large fingernail, and needs to be trimmed (and horseshoes reset, if used) every six to eight weeks.

The senses of a horse are generally superior to those of a human. As prey animals, they must be aware of their surroundings at all times. They have very large eyes (among land animals only the ostrich has a larger eye), with excellent day and night vision, though they may have a limited range of color vision. The side positioning of the eyes gives the horse a wide field of vision of about 350°. While not color-blind, studies indicate that they have difficulty distinguishing greens, browns and grays. Their hearing is good, and the pinna of their ears can rotate a full 360 degrees in order to pick up sound from any direction. Their sense of smell, while much better than that of humans, is not their strongest asset; they rely to a greater extent on vision.

A horse's sense of balance is outstanding; the cerebellum of their brain is highly developed and they are very aware of terrain and placement of their feet. Horses' sense of touch is better developed than many people think; they immediately notice when a fly or mosquito lands on them, even before the insect attempts to bite. Their sense of taste is well-developed in order to determine the nature of the plants they are eating, and their prehensile lips can easily sort even the smallest grains. Horses will seldom eat most poisonous plants or spoiled food unless they have no other choices, although a few toxic plants have a chemical structure that appeals to animals, and thus poses a greater risk of being ingested.

All horses move naturally with four basic gaits: the walk, trot or jog, canter or lope, and gallop. Besides these basic gaits, some horses pace, instead of trot. In addition, there are many "ambling" gaits such as the slow gait, rack, fox trot running walk, and tölt. These special gaits are often found in specific breeds, often referred to as "gaited" horses because they naturally possess additional gaits that are approximately the same speed as the trot but smoother to ride. Technically speaking, "gaited horses" replace the standard trot (which is a 2 beat gait) with one of the four beat gaits.

Horse breeds with additional gaits that often occur naturally include: the Tennessee Walking Horse which naturally performs a running walk; the American Saddlebred which can be trained to exhibit a slow gait and the rack; Paso Fino, which has two ambling gaits, the paso corto and paso largo; the Peruvian Paso, which exhibits the paso llano, and sobreandando; and Icelandic horses which are known for the tölt. The fox trot is found in several breeds, most notably the Missouri Foxtrotter. Standardbreds, depending on bloodlines and training, may either pace or trot.

Horses are animals that were evolved to graze. They eat grass or hay, sometimes supplemented with grain. They require a plentiful supply of clean water, a minimum of 10 to 12 gallons per day. Although horses are adapted to live outside, they require shelter from the wind and precipitation, which can range from a simple shed or shelter to an elaborate stable.

Horses require annual vaccinations to protect against various diseases, need routine hoof care by a farrier, and regular dental examinations from a veterinarian or a specialized equine dentist. If horses are kept inside in a barn, they require regular daily exercise for their physical health and mental well-being. When turned outside, they require well-maintained, sturdy fences to be safely contained. Regular grooming is also helpful to help the horse maintain good health of the hair coat and underlying skin.

Horses are trained to be ridden or driven in many different sporting events and competitions. Examples include horse shows, gymkhana and O-Mok-See, rodeos, endurance riding, fox hunting, and Olympic-level events such as three-day eventing, combined driving, dressage, and show jumping. Although scoring varies by event, most emphasize the horse's speed, maneuverability, obedience and/or precision. Sometimes the equitation, the style and ability of the rider, is also considered.

Sports such as polo and horseball do not judge the horse itself, but rather use the horse as a partner for human competitors as a necessary part of the game. Although the horse assists this process and requires specialized training to do so, the details of its performance are not judged, only the result of the rider's actions -- be it getting a ball through a goal or some other achievement. Examples of these sports of partnership between human and animal also include jousting (reenacting the skills used by medieval knights), where the main goal is for one rider to dismount the other, and buzkashi, a team game played throughout Central Asia, the aim being to capture a goat carcass while on horseback.

The most widely known use of horses for sport is horse racing, seen in almost every nation in the world. There are three types: "flat" racing; steeplechasing, i.e. racing over jumps; and harness racing, where horses trot or pace while pulling a driver in a small, light cart known as a sulky. Most race horses in the developed world are Thoroughbreds, a breed which can reach speeds up to 40 mph/70 km/h. In the case of a specialized sprinting breed, the American Quarter Horse, speeds over 50 mph have been clocked. In harness racing, performed by Standardbred horses, speeds over 30 mph have been measured. A major part of the economic importance of horse racing, as for many sports, lies in the gambling associated with it.

There are certain jobs that horses do very well, and no amount of technology appears able to supersede. Mounted police horses are still effective for crowd control. Cattle ranches still require riders on horseback to round up cattle that are scattered across remote, rugged terrain. Search and rescue organizations in some countries depend upon mounted teams to locate people, particularly hikers and hunters, who are lost in remote areas.

Some land management practices such as cultivating and logging can be efficiently performed with horses. In agriculture less use of fossil fuels, reduced soil compaction and degrading of soil structure can be seen over time with the use of draft animals such as horses. In forestry, logging can be done with horses and can result in reduced damage to soil structure and less damage to trees due to more selective logging.

Horses can also be used in other areas where it is necessary to avoid vehicular disruption to delicate soil. Examples include areas such as a nature reserve. They may also be the only form of transport allowed in wilderness areas. They are also quieter than motorized vehicles. Peace officers such as rangers or game wardens may use horses for patrols, and horses may also be used for clearing trails or other work in areas of rough terrain where vehicles are less effective.

In less affluent countries such as Romania, Kyrgyzstan, and many parts of the Third World, horses, donkeys and mules are routinely used for transport and agriculture. In areas where roads are poor or non-existent and fossil fuels are scarce or the terrain rugged, riding horseback is still the most efficient way to get from place to place.

People with disabilities obtain beneficial results from association with horses. The movement of a horse strengthens muscles throughout a rider's body and promotes better overall health. In many cases, riding has also led to increased mobility for the rider. Horses also provide psychological benefits to people whether they actually ride or not. The benefits of equestrian activity for people with disabilities has also been recognized with the addition of equestrian events to the Paralympic Games and recognition of para-equestrian events by the FEI.

Hippotherapy and therapeutic horseback riding are names for different physical, occupational and speech therapy treatment strategies that utilize equine movement. In the hippotherapy environment, a therapist uses the horse's movement to provide carefully graded sensory input, whereas therapeutic horseback riding uses specific riding skills.

"Equine-assisted" or "equine-facilitated" psychotherapy uses horses as companion animals to assist people with psychological problems. Actual practices vary widely due to the newness of the field; some programs include Therapeutic Horseback Riding and hippotherapy. Non-riding therapies simply encourage a person to touch, speak to and otherwise interact with the horse. People appear to benefit from being able to be around a horse; horses are very sensitive to non-verbal communication and are an ideal resource for working with individuals who have "tuned out" human therapists.

Equine Assisted Learning (EAL), Equine guided education, or equine assisted professional development, is another relatively new field of experiential learning for corporate, professional and personal development. There also have been experimental programs using horses in prison settings. Exposure to horses appears to improve the behavior of inmates in a prison setting and help reduce recidivism when they leave. A correctional facility in Nevada has a successful program where inmates learn to train young mustangs captured off the range in order to make it more likely that these horses will find adoptive homes. Both adult and juvenile prisons in New York, Florida, and Kentucky work in cooperation with the Thoroughbred Retirement Foundation to re-train former racehorses as pleasure mounts and find them new homes. Horses are also used in camps and programs for young people with emotional difficulties.
