Waterton relates an anecdote showing the daring ferocity of the creature when pressed by hunger. It was on the banks of the Orinoco, near the city of Angostura. The tale was told him by the governor of that place.

"One fine evening, as the people of the city were sauntering up and down the alamada by the banks of the river, a large cayman rushed out of the water, seized a man, and carried him down, before any person had it in his power to a.s.sist him. The screams of the poor fellow were terrible as the cayman was running off with him. The monster plunged into the river with its prey, and we instantly lost sight of him, and never saw or heard of him more."

Bates also relates that a native crew, having arrived at Egga, got drunk, when one of the men, during the greatest heat of the day, while everybody else was enjoying an afternoon nap, took it into his head, while in a tipsy state, to go down alone to bathe. He was seen only by a feeble old man, who was lying in his hammock in the open verandah at the rear of his house, at the top of the bank. He shouted to the besotted Indian to beware of an alligator which had of late taken to frequenting the neighbourhood. Before he could repeat his warning, the man stumbled, and a pair of gaping jaws, appearing suddenly above the surface, seized him round the waist, and drew him under the water. A cry of agony--"Ai Jesus!"--was the last sound made by the wretched victim. The young men of the village, going in search of the monster, came up with it when, after a little time, it rose to breathe, with one leg of the man sticking out from its jaws. It was immediately despatched, with bitter curses.

One night Bates and his party were asleep in their hammocks in an open shed on the banks of the river, with a fire made up in the centre. He was awoke by his attendants hurling burning firewood, with loud curses, at a huge cayman which had crawled up the bank, and pa.s.sed beneath his hammock towards the place where a little dog lay asleep. The dog had raised the alarm in time. The reptile backed out, and tumbled down the bank into the water, the sparks of the brands hurled at him flying from his back and sides. Notwithstanding this, the next night he repeated his visit.

The alligator, in its daring attempts to seize human beings, does not always come off victorious. An Indian and his son had gone down to the water, when the boy, whilst bathing, was seized by the thigh, and carried under. The father, rushing down the bank, plunged after the rapacious beast, which was diving away with its victim. He followed it unarmed, and overtaking the creature, thrust his thumb into its eye, and forced it to release its booty. The lad, who was present when the story was told, exhibited the marks of the alligator's teeth in his thigh.

On another occasion an alligator was shot by one of the pa.s.sengers on board a steamer, and hauled up on deck. When the knife was applied, it showed that it still possessed some sparks of life, by lashing out its tail, and opening its enormous jaws, sending the crowd of bystanders flying in all directions. It is extraordinary how tenacious the creature is of life, and what a prodigious amount of battering it may receive and still live.

Fortunately for other animals, the young alligators have numerous enemies, even the males of their own kind occasionally gobbling them up; while they are terribly persecuted by wild beasts and birds of prey,-- the latter esteeming their soft bodies delicate morsels, and frequently pouncing down into their midst and carrying them off.

The alligator, far from being a silent animal, as is generally supposed, makes a hideous noise at times, bellowing with so singular a cadence and loud a din, that he can even outroar the jaguars and mycetes.

Sir Richard Schombergh describes the way in which the alligator seizes its prey. He secured a bird or fish to a piece of wood, and then turned it adrift on the river. No sooner was it seen than a cayman, slowly and cautiously approaching--without even rippling the surface of the water-- and then curving its back, hurled its prey by a stroke of its tail into its wide-extended jaws.

It makes also a loud sound, by clacking its teeth, and lashing its tail on the water. It has a voice not readily to be distinguished from that of the animals of the forest. It is similar to a hollow suppressed sigh bursting forth on a sudden, loud enough to be heard a mile off. First one gives vent to this fearful sound, then another answers from a distance; and from up and down the river, and across the current, these horrible noises are heard, showing that the hideous saurians are in a lively mood, watching for their suppers. It is supposed that when once they have tasted human flesh they will always endeavour again to procure it.

Humboldt mentions another instance, where an Indian, landing on the banks of a shallow lagoon, was seized by a cayman. With wonderful presence of mind the Indian searched for a knife, but not finding it, he pressed his fingers into its eyes. The monster, however, did not let go, but dragged the unfortunate man down into deep water, and, to the horror of several spectators, was seen swimming off with the poor fellow in its jaws, to devour him on a neighbouring island.

Humboldt states that during the inundations of the Orinoco, alligators have been known to crawl into the streets of Angostura and carry off human beings.

Schombergh once saw an enormous cayman seize one of a smaller species, and bear it away--not, however, without a desperate struggle. In a short time the monsters reappeared, wildly beating the surface with their tails. Now a huge head rose up, now a tail, indistinctly seen in the seething whirlpool. At length, however, the larger was beheld swimming off to a sand-bank, where it immediately began to devour its prey.

THE IGUANA.

See yonder hideous-faced creature, nearly six feet in length, the size of many alligators, its head covered with scaly plates, a huge dewlap depending from its throat, its body and long tail covered with small imbricated scales, its back garnished with a row of spines, and on its thigh a number of porous tubercles, while its legs and claws are wide-spreading.

As it crawls along a bough overhead, the bravest man who had never before seen it would undoubtedly get out of its way, expecting it to leap down and seize him. Yet the iguana, ugly as is its countenance, is perfectly harmless; except that it can give a sharp bite with its compressed triangular and serrated teeth. It lives generally on trees.

When hard-pressed it takes to the water, and swims with ease,--pressing its legs close to its sides, and sculling itself on with its tail; while it can remain an hour or more under water without suffering.

The flesh of the iguana, unfortunately for itself, is considered excellent; and hunters go out to catch it with a noose at the end of a long stick, which they cast round its neck, and then by a sudden jerk pull it to the ground. As the creature seems to fancy that it cannot be reached on the bough, it seldom moves on the approach of the hunter, and is thus easily caught. It lashes out with its tail, however, and tries to bite, when once it finds itself entrapped; and being also very tenacious of life, it is not killed without repeated heavy blows, or a pistol-shot in its head.

The common iguanas are numerous in the neighbourhood of villages, where they climb the trees for the sake of their fruit. Some species lay their eggs--which are about an inch and a half in length, and oblong--in hollow trees. Others are known to do so in the sand, to be hatched by the heat of the sun. They are considered delicacies, and are much sought after in consequence.

The colour of the iguana changes, like that of the chameleon. The Brazilians, indeed, call it the chameleon. Its food consists almost entirely of fruits and other vegetable substances, though some species are supposed to be omnivorous. The natives frequently tame it, when it willingly allows itself to be carried about by its owner, though it at once distinguishes strangers.

There are, however, numerous species of iguanas; indeed, the family contains fifty genera--the true iguanas being all inhabitants of the New World. To its predecessor, which it closely resembles in bony structure, the largest is but a mere pigmy--for that extinct monster must have been about seventy feet in length, the length of the tail alone being fifty-two feet, and the circ.u.mference of the body fourteen and a half feet; while its thigh-bone was twenty times the size of that of the modern iguana. Vast as was the inhabitant of the ancient world, it was herbivorous, like that of the comparatively Lilliputian creature of the present day.

Everywhere the agile, beautifully-tinted lizards abound, sunning themselves on logs of wood, or scampering over the sandy soil. Now they may be seen turning round the trunk of a tree, much as a squirrel does, watching the pa.s.ser-by, and trying to keep out of sight. Some are of a dark coppery colour, others have backs of the most brilliant silky green and blue, while others are marked with delicate shades of yellow and brown.

The largest of their family is the teguexin, or variegated lizard.

Sometimes it is called the safeguard, from the idea--probably an idle fable--that, like the monitors of the Nile, they give notice of the approach of the alligator by their loud hissing.

There are several species which inhabit the hot, sandy plains, or dense, damp underwood near the rivers and lakes. One of them exceeds five feet in length, and is extremely active. It feeds almost entirely on snakes, frogs, and toads, but occasionally devours poultry, and breakfasts off their eggs. It is also somewhat of a cannibal, for though it will not eat its own species, it does occasionally those of a somewhat smaller lizard allied to it. It possesses strong teeth, and can bite with great force; indeed, when attacked it defends itself fiercely, and when seizing a foe can seldom be compelled to let go.

Its colour is variable, but generally the upper parts of the body are deep black, with mottlings of yellow or green; while on the higher portions of its sides are a series of white spots, the under part being chiefly yellow, with black bands.

The little ameiva, on which it occasionally preys, is of a dark olive colour, speckled with black about the neck.

There is another large lizard, known as the great dragon (Ada Guianensis). It is of an olive colour, with yellow below, and mottled with brown; and frequently attains a length of six feet. While the former cannot climb trees, it is a good swimmer. The great dragon climbs with wonderful agility, but is said not to be very much at home in the water. It also bites fiercely.

Both are hunted for the sake of their flesh; while their eggs--of which thirty or forty are laid--are considered great delicacies.

GECKOS.

Not only in the huts of the natives, but in the abodes of the wealthy white men, hid during the day in dark corners, are numbers of dark grey, hideous-looking lizards, which, when night comes on, crawl rapidly over the walls and ceilings, hunting for the flies and other insects to be found there. Repulsive as are these little geckos, and undeservedly possessing a bad name for being poisonous, they are not only harmless, but render good service by the destruction of numerous household pests.

Their large eyes are so constructed that they can discern objects in the dark, and are at the same time capable of bearing the rays of the bright sun. Their colour, too, enables them to escape detection by the creatures which attack them, while they are thus hid from the prey for which they lie in wait. They can also bend themselves in an extraordinary way into hollows and crevices.

But their feet are especially curious, being admirably adapted for clinging to and running over smooth surfaces. The under side of their toes is expanded into cushions, beneath which folds of skin form a series of flexible plates. By means of this apparatus they can run or crawl across a smooth ceiling with their backs downwards--the soft soles, by quick, muscular action, exhausting and admitting air alternately. They are also provided with sharp claws, which enable them to climb up the trunks of trees, and over rough surfaces.

The Brazilians call them osgas, and believe that they poison by their touch whatever they pa.s.s over. Probably, however, if any annoyance does arise from them, it is when with their sharp claws they run across a sleeping man, or small blisters have been raised by the adhering apparatus at the bottom of their feet. By some "the spider, which taketh hold with her hands," is believed to be a gecko, as a species of this creature is very common in the East. The popular prejudice against them causes the death of many a poor gecko, who, had he been allowed to live, would have rendered good service to his persecutors. Those in the houses are of small size; but others, existing in the forest, and living in the crevices of the trees, are of considerable magnitude. Their tails are easily struck off--the loss being, however, as is the case with other lizards, repaired by a new growth, though less perfect than the original member.

THE ANACONDA.

With its ill-favoured head protruding above the surface of the water near the banks of slow-flowing rivers, pools, and swamps, the vast anaconda lies in wait for its prey. The fish swimming along in its neighbourhood,--the birds which, rising from the reeds, skim by overhead,--the animals which come to the banks to drink,--even man himself, have cause to dread a blow from the snout, and the powerful coils of the huge water-serpent. Its appearance is most hideous, being very broad in the middle, and tapering abruptly at both ends. Fish, and the smaller animals, it swallows whole; but a larger animal it seizes by the nose with its powerful jaws, and surrounds with the mighty coils of its huge body, pressing one coil upon another till it crushes its prey to death.

Though generally found from twenty to thirty feet in length, it is said to attain a length of forty feet; and one of that size is fully capable of swallowing an ox or horse,--there being many instances of its having been done. Its voracity is prodigious. The French naturalist Firmin found in the stomach of an anaconda a large sloth, an iguana four feet long, and a good-sized ant-bear; all three in the same state almost as when they were swallowed--a proof that they had been captured within a short time. Bates relates that an Indian father with his son went one day in their montario to gather fruit a short distance from Egga, when, landing on a sloping, sandy sh.o.r.e, the boy was left to take care of the canoe while the man entered the forest. The boy was playing in the water under the shade of some myrtle and wild guava trees, when a huge reptile stealthily wound its coils round him. His cries brought the father to the rescue, who, rushing forward, seized the anaconda boldly by the head, and tore its jaws asunder.

This formidable serpent lives to a great age; and Bates heard of a specimen being killed which measured forty-two feet in length. Those he measured were only twenty-one feet long, and two feet in girth. He was a sufferer, on one occasion, from one of these. While on a voyage up the river, his canoe being moored alongside the bank, the neighbourhood of which had been haunted for some time past by one of the creatures, he was awoke a little after midnight, as he lay in his cabin, by a heavy blow struck at the side of the canoe, close to his head. It was succeeded by the sound of a heavy body plunging into the water. When he got up all was again quiet, except the cackle of fowls in the hen-coop, which hung at the side of the vessel, about three feet from the cabin door. In the morning the poultry were found loose about the canoe, two of the fowls being missing; while there was a large rent in the bottom of the hen-coop, raised about two feet from the surface of the water.

The Indians went in search of the reptile, which, being found sunning itself on a log at the mouth of a muddy rivulet, was despatched with harpoons.

It is extremely tenacious of life; and though the head may be nearly cut off, and the entrails taken out, it will still move about for a considerable time. It is detested by the farmers on the banks, as it has the habit of carrying off poultry, young calves, or any animal it can get within reach of. It is often seen coiled up in the corner of farm-yards, waiting for its prey.

The statement that the anaconda kills its prey by its pestilent breath, is wholly fabulous. Waterton altogether denies the existence of any odour in the snake's breath. It is possible, however, that some species may produce a horrible stench, from a substance secreted in certain glands near the tail--a fact which has probably given rise to the fable.

THE BOA.

Among the semi-civilised, idolatrous inhabitants of the continent, several snakes were objects of worship. The boa-constrictor especially was regarded as an emblem of strength and power, from its vast size, and the fearful effect produced by its encircling coils as it winds itself round the body of its victim.

See the creature as its shining body moves rapidly among the fallen leaves and dried husks in the forest, rather like a stream of brown liquid than a serpent, with skin of varied colours! Onwards it goes, with scarcely a perceptible serpentine movement. Even the huge trunk of a fallen tree does not stop it, but it glides over the impediment in its undeviating course, making the dry twigs crack and fly off with its weight. Now it stops, watching for its prey. An agouti runs by, regardless of the seeming rivulet; but the hapless creature is seized by the serpent's jaws, and those terrible folds surrounding the body--coil above coil--crush the bones, till it becomes a mere ma.s.s of flesh. And now it begins to suck in its prey; not lubricating it, as is generally stated, although a large quant.i.ty of saliva surrounds the animal while it is descending the monster's throat. After a time the meal is finished, and the serpent--its body greatly distended--remains at rest, unwilling to move, when it may be easily captured by the daring hunter.

The body of the boa is of a rich brown colour. A broad chain of large black spots, alternating with white, runs along its back; while the scales round the eyes are set in a circle, separated from those of the lips by two rows of smaller scales. The jaws are not united, but attached to the skull by muscles and ligaments, which enable it to dilate the mouth sufficiently to swallow bodies much larger than itself.

The largest grow to a length of thirty feet and upwards; but boas ordinarily do not attain more than twenty feet in length.

THE SPOTTED BOA.

The boa scytale, or spotted boa, is of a greyish colour, marked with round spots, and scarcely inferior in size to the former.

THE RINGED BOA.

There is another species--the ringed boa, or boa cenchris--which, though growing to a considerable size, does not attain that of the former species.

A curious species (the boa canina) has a large head, shaped somewhat like that of a dog; the general colour a bright Saxon-green, with transverse white bars down the back. The sides are of a deeper green, and the belly is white.

Wallace describes a small one only eleven feet in length, but as thick as a man's thigh. It was secured by having a stick tightly tied round the neck. It went about dragging its clog with it, sometimes opening its mouth with a very suspicious yawn, and sometimes turning its tail up into the air. Being put into a cage, and released from the stick, it began to breathe most violently, the expirations sounding like high-pressure steam escaping from a Great Western locomotive.
