It is equally indispensable in warm climates, that a horse should possess an easy gait for travelling. In this respect, they are trained to the particular fancy or requirements of the rider. Some prefer a gentle trot on a long journey, as being the least fatiguing to the horse; but, for city riding, or short journeys, an amble, rack, or pasitrote—something between both—is usually adopted. The test of a good pacing horse consists in “the rider being able to carry a glass of water in his hand without spilling,” while that of a first-rate charger is to stop, when at the height of his speed, on the slightest pull of the bridle.

Great regard is also paid to the color of horses; piebald, cream, and the various shades of white, are usually preferred. But, where great endurance and strength are requisite, connoisseurs generally select those of a darker color. Their price in the country is greatly enhanced of late in consequence of a devastating disease, which has been raging among them for several years past. Horses were so plentiful in the Llanos at one time, that a large export trade in their hides was carried on with foreign countries. A good horse, which then only brought five dollars, now costs from eighty to one hundred, and even more, according to the fancy of the parties interested.—Great numbers of the inhabitants were also carried away by the same scourge, which swept over the land like the cholera, not even sparing the fish in the rivers.

This frightful epidemic, which the Llaneros have appropriately styled Peste, or plague, is supposed to have originated in the great primeval forest of San Camilo, at the head waters of the Apure, from decomposition of the vegetable detritus accumulated there during centuries. From thence, travelling eastward along the course of the river, the epidemic continued its ravages among the inhabitants of the towns and villages situated on the right bank, attacking first one place and then another, until the whole province scarcely escaped depopulation. Even when the mortality abated, the country, which until then had possessed a most healthful climate, never recovered its former salubrity; fevers of a more or less dangerous character prevail from that time, especially towards the end of the rainy season, while the raising of horses has been entirely abandoned in consequence.

The first symptoms of the epidemic appeared among the crocodiles, whose hideous carcasses might then be seen floating down the stream in such prodigious numbers, that both the waters and air of that fine region were tainted with their effluvium. It was observed that they were first seized with a violent fit of coughing, followed by a black vomit which compelled them to quit their watery home, and finally find a grave amongst the thickets on the river banks. The disease next attacked the fish and other inhabitants of the water, with equal violence, until it was feared the streams would be depopulated. The fearful mortality among them can be better estimated from the fact that, for more than a month, the rippling waves of that noble river, the Apure, were constantly washing down masses of putrefaction, its placid surface being by them actually hidden from view for several weeks.

The next victims were the pachidermata of the swamps, and it was a pitiable sight to see the sluggish chigüires (capyvaras) and the grizzly wild-boars dragging their paralyzed hind-quarters after them; hence the name of derrengadera, applied to this disease.

Not even monkeys in their aërial retreats, escaped the contagion, and their melancholy cries resounded day and night through the woods like wailings of the eternally lost.

It is a singular fact, that while the scourge did not spare any of the countless droves of horses roaming the savannas of the Apure, and adjacent plains, donkeys and horned cattle were seldom, if ever, attacked, so that, by their aid, the owners of cattle-farms were enabled to prevent the entire dispersion of their herds.

A curious incident related in connection with this public calamity, is very current in the Llanos, respecting the origin of the disease among horses. Eugenio Torralva, a man of uncommon industry, although of humble extraction, had accumulated quite a handsome fortune by the raising of cattle, on the borders of La Portuguesa; but his chief wealth consisted in horses, on which he greatly prided himself—so much so that, on one occasion, while a distinguished personage was passing through his estate, Torralva directed his attention to the numerous droves grazing in the plains; then turning to his guest, who appeared equally delighted with the sight, said to him, “Think you, General, that I shall ever be in want of horses? Ni que Dios quiera! (Not even if God Almighty wished it!)” he blasphemously added. Two years later, the witness to this impious boast was again on his way to the Llanos: near San Juan he met an old man, apparently in a very destitute condition, riding a donkey. Not knowing who the wayfarer was, he bowed, as is customary, and rode on without taking further notice of the old man or his uncouth equipment; whereupon the stranger, waving his hand to him, cried, “Why, General, have you already forgotten your friend Torralva?” He that “giveth and taketh away” had deprived him of every horse, and the once wealthy farmer was now compelled to travel on an ass. It is asserted by the Llaneros that soon after he uttered the above-mentioned blasphemy, the Peste broke out among his immense stock, from whence they say the disease spread to other farms, until the contagion became general.

It is not a little singular that although the horse was unknown to the aborigines of America, at the time of its conquest, the researches of Darwin and other eminent geologists have shown them to have existed in vast numbers on that continent contemporaneously with the Mastodon, Megatherium, Mylodon, and other extinct animals. “Certainly, it is a marvellous fact, in the history of mammalia,” observes that assiduous explorer, “that in South America a native horse should have lived and disappeared, to be succeeded, in after ages, by the countless herds descended from the few introduced by the Spanish colonists!”

In general these animals are of middling size, and, like their progenitor, the Andalusian horse, endowed with a fiery spirit, (if not checked by ill-treatment or abuse,) and surprising endurance, especially during the exciting chase of wild cattle, when they are kept in constant motion for many consecutive days.
