Eight Years' Wanderings in Ceylon Part 14

Observe the particular quarters of a city which suffers most severely during the prevalence of an epidemic, In all dirty, narrow streets, where the inhabitants are naturally of a low and uncleanly cla.s.s, the cases will be tenfold. Thus, filth is admitted to have at least the power of attracting disease, and we know that it not only attracts, but generates animalcules; therefore filth, insects and disease are ever to be seen closely linked together.

Now, the common preventives against infection are such as are peculiarly inimical to every kind of insect; camphor, chloride of lime, tobacco-smoke, and powerful scents and smokes of any kind. The first impulse on the appearance of an infectious disease is to purify everything as much as possible, and by extra cleanliness and fumigations to endeavor to arrest its progress. The great purifier of Nature is a violent wind, which usually terminates an epidemic immediately; this would naturally carry before it all insect life with which the atmosphere might be impregnated, and the disease disappears at the same moment. It will he well remembered that the plague of locusts inflicted upon Pharaoh was relieved in the same manner: "And the Lord turned a mighty strong west wind, which took away the locusts and cast them into the Red Sea; there remained not one locust in all the coasts of Egypt."

Every person is aware that unwholesome air is quite poisonous to the human system as impure water; and seeing that the noxious qualities of the latter are caused by animalcules, and that the method used for purifying infected air are those most generally destructive to insect life, it is not irrational to conclude that the poisonous qualities of bad water and bad air arise from the same cause.

Man is being constantly preyed upon by insects; and were it not for ordinary cleanliness, he would become a ma.s.s of vermin; even this does not protect him from the rapacity of ticks, mosquitoes, fleas and many others. Intestinal worms feed on him within, and, unseen, use their slow efforts for his destruction.

The knowledge of so many cla.s.ses which actually prey upon the human system naturally leads to the belief that many others endowed with the same propensities exist, of which we have at present no conception.

Thus, different infectious disorders might proceed from peculiar species of animalcules, which, at given periods, are wafted into certain countries, carrying pestilence and death in their invisible course.

A curious phenomenon has recently occurred at Mauritus, where that terrible scourge, the cholera, has been raging with desolating effect.

There is a bird in that island called the "martin," but it is more property the "mina." This bird is about the size of the starling, whose habits its possesses in a great degree. It exists in immense numbers, and is a grand destroyer of all insects. On this account it is seldom or never shot at, especially as it is a great comforter to all cattle, whose hides it entirely cleans from ticks and other vermin, remaining for many hours perched upon the back of one animal, while its bill is actively employed in searching out and destroying every insect.

During the prevalence of the cholera at Mauritius these birds disappeared. Such a circ.u.mstance had never before occurred, and the real cause of their departure is still a mystery.

May it not have been, that some species of insect upon which they fed had likewise migrated, and that certain noxious animalcules, which had been kept down by this cla.s.s, had thus multiplied within the atmosphere until their numbers caused disease? All suppositions on such a subject must, however, remain in obscurity, as no proof can be adduced of their correctness. The time may arrive when science may successfully grapple with all human ailments, but hitherto that king of pestilence, the "cholera," has reduced the highest medical skill to miserable uncertainty.

Upon reconsidering the dangers of fevers, dysentery, etc., in the swampy and confined districts described, the naturalist may become somewhat less ardent in following his favorite pursuit. Of one fact I can a.s.sure him that no matter how great the natural strength of his const.i.tution, the repeated exposure to the intense heat of the sun, the unhealthy districts that he will visit, the nights redolent of malaria, and the horrible water that he must occasionally drink, will gradually undermine the power of the strongest man. Both sportsman and naturalist in this must share alike.

No one who has not actually suffered from the effect can appreciate the misery of bad water in a tropical country, or the blessings of a cool, pure draught. I have been in districts of Ceylon where for sixteen or twenty miles not a drop of water is to be obtained fit for an animal to drink; not a tree to throw a few yards of shade upon the parching ground; nothing but stunted, th.o.r.n.y jungles and sandy, barren plains as far as the eye can reach; the yellow leaves crisp upon the withered branches, the wild fruits hardened for want of sap, all moisture robbed from vegetation by the pitiless drought of several months.

A day's work in such a country is hard indeed carrying a heavy rifle for some five-and-twenty miles, sometimes in deep sand, sometimes on good ground, but always exposed to the intensity of that blaze, added to the reflection from the sandy soil, and the total want of fresh air and water. All Nature seems stagnated; a distant pool is seen, and a general rush takes place toward the cheering sight. The water is thicker than pea soup, a green sc.u.m floats through the thickened ma.s.s, and the temperature is upward of 130 Fahrenheit. All kinds of insects are swarming in the putrid fluid, and a saltish bitter adds to its nauseating flavor. I have seen the exhausted coolies spread their dirty cloths on the surface, and form them into filters by sucking the water through them. Oh for a gla.s.s of Newera Ellia water, the purest and best that ever flows, as it sparkles out of the rocks on the mountain-tops! what pleasure so perfect as a long, deep and undisturbed draught of such cold, clear nectar when the throat is parched with unquenchable thirst!

In some parts of Ceylon, especially in the neighborhood of the coast, where the land is flat and sandy, the water is always brackish, even during the rainy season, and in the dry months it is undrinkable.

The natives then make use of a berry for cleansing it and precipitating the impurities. II know the shrub and the berry well, but it has no English denomination. The berries are about the size of a very large pea, and grow in cl.u.s.ters of from ten to fifteen together, and one berry is said to be sufficient to cleanse a gallon of water. The method of using them is curious, although simple. The vessel which is intended to contain the water, which is generally an earthen chatty, is well rubbed in the inside with a berry until the latter, which is of a h.o.r.n.y consistency, like vegetable ivory, is completely worn away. The chatty is then filled with the muddy water, and allowed to stand for about an hour or more, until all the impurities have precipitated to the bottom and the water remains clear.

I have constantly used this berry, but I certainly cannot say that the water has ever been rendered perfectly clear; it has been vastly improved, and what was totally undrinkable before has been rendered fit for use; but it has at the best been only comparatively good; and although the berry has produced a decided effect, the native accounts of its properties are greatly exaggerated.

During the prolonged droughts, many rivers of considerable magnitude are completely exhausted, and nothing remains but a dry bed of said between lofty banks. At these seasons the elephants, being hard pressed for water, make use of their wonderful instinct by digging holes in the dry sand of the river's bed; this they perform with the h.o.r.n.y toes of their fore feet, and frequently work to a depth of three feet before they discover the liquid treasure beneath. This process of well-digging almost oversteps the boundaries of instinct and strongly, savors of reason, the two powers being so nearly connected that it is difficult in some cases to define the distinction. There are so many interesting cases of the wonderful display of both these attributes in animals, that I shall notice some features of this subject in a separate chapter.

CHAPTER IX.

Instinct and Reason--Tailor Birds and Grosbeaks--The White Ant--Black Ants at War--Wanderoo Monkeys--Habits of Elephants--Elephants in the Lake--Herd of Elephants Bathing--Elephant-shooting--The Rencontre--The Charge--Caught by the Tail--Horse Gored by a Buffalo--Sagacity of Dogs--"Bluebeard"--His Hunt--A True Hound.

There can be no doubt that man is not the only animal endowed with reasoning powers: he possesses that faculty to an immense extent, but although the amount of the same power possessed by animals may be infinitely small, nevertheless it is their share of reason, which they occasionally use apart from mere instinct.

Although instinct and reason appear to be closely allied, they are easily separated and defined.

Instinct is the faculty with which Nature has endowed all animals for the preservation and continuation of their own species. This is accordingly exhibited in various features, as circ.u.mstances may call forth the operation of the power; but so wonderful are the attributes of Nature that the details of her arrangements throughout the animal and insect creation give to every cla.s.s an amount of sense which in many instances surmounts the narrow bounds of simple instinct.

The great characteristic of sheer instinct is its want of progression; it never increases, never improves. It is possessed now in the nineteenth century by every race of living creatures in no larger proportion than was bestowed upon them at the creation.

In general, knowledge increases like a rolling s...o...b..ll; a certain amount forms a base for extra improvement, and upon successive foundations of increasing alt.i.tude the eminence has been attained of the present era. This is the effect of "reason;" but "instinct,"

although beautiful in its original construction, remains, like the blossom of a tree, ever the same--a limited effect produced by a given cause; an unchangeable law of Nature that certain living beings shall perform certain functions which require a certain amount of intelligence; this amount is supplied by Nature for the performance of the duties required; this is instinct.

Thus, according to the requirements necessitated by the habits of certain living creatures to an equivalent amount is their share of instinct. Reason differs from instinct as combining the effects of thought and reflection; this being a proof of consideration, while instinct is simply a direct emanation from the brain, confined to an impulse.

In our observations of Nature, especially in tropical countries, we see numberless exemplifications of these powers, in some of which the efforts of common instinct halt upon the extreme boundary and have almost a tinge of reason.

What can be more curious than the nest of the tailor-bird--a selection of tough leaves neatly sewn one over the other to form a waterproof exterior to the comfortable little dwelling within? Where does the needle and thread come from? The first is the delicate bill of the bird itself, and the latter is the strong fibre of the bark of a tree, with which the bird sews every leaf, lapping one over the other in the same manner that slates are laid upon a roof.

Nevertheless this is simple instinct; the tailor-bird in the days of Adam constructed her nest in a similar manner, which will be continued without improvement till the end of time.

The grosbeak almost rivals the tailor-bird in the beautiful formation of its nest. These birds build in company, twenty or thirty nests being common upon one tree. Their apparent intention in the peculiar construction of their nests is to avoid the attacks of snakes and lizards. These nests are about two feet long, composed of beautifully woven gra.s.s, shaped like an elongated pear. They are attached like fruit to the extreme end of a stalk or branch, from which they wave to and fro in the wind, as though hung out to dry. The bird enters at a funnel-like aperture in the bottom, and by this arrangement the young are effectually protected from reptiles.

All nests, whether of birds or insects, are particularly interesting, as they explain the domestic habits of the occupants; but, however wonderful the arrangement and the beauty of the work as exhibited among birds, bees, wasps, etc., still it is the simple effect of instinct on the principle that they never vary.

The white ant--that grand destroyer of all timber--always works under cover; he builds as he progresses in his work of destruction, and runs a long gallery of fine clay in the direction of his operations; beneath this his devastation proceeds until he has penetrated to the interior of the beam, the centre of which he entirely demolishes, leaving a thin sh.e.l.l in the form of the original log encrusted over the exterior with numerous galleries.

There is less interest in the habits of these destructive wretches than in all other of the ant tribe; they build stupendous nests, it is true, but their interior economy is less active and thrifty than that of many other species of ants, among which there is a greater appearance of the display of reasoning powers than in most animals of a superior cla.s.s.

On a fine sunny morning it is not uncommon, to see ants busily engaged in bringing out all the eggs from the nest and laying them in the sun until they become thoroughly warmed, after which they carry them all back again and lay them in their respective places. This looks very like a power of reasoning, as it is decidedly beyond instinct. If they were to carry out the eggs every morning, wet or dry, it would be an effort of instinct to the detriment of the eggs; but as the weather is uncertain, it is an effort of reason on the part of the ants to bring out the eggs to the sun, especially as it is not an every-day occurrence, even in fine weather.

In Mauritius, the negroes have a custom of turning the reasoning powers of the large black ant to advantage.

White ants are frequently seen pa.s.sing in and out of a small hole from underneath a building, in which case their ravages could only be prevented by taking up the flooring and destroying the nest.

The negroes avoid this by their knowledge of the habits of the black ant, who is a sworn enemy to the white.

They accordingly pour a little treacle on the ground within a yard of the hole occupied by the white ants. The smell of the treacle shortly attracts some of the black species, who, on their arrival are not long in observing their old enemies pa.s.sing in and out of the hole. Some of them leave the treacle; these are evidently messengers, as in the course of the day a whole army of black ants will be seen advancing, in a narrow line of many yards in length, to storm the stronghold of the white ants. They enter the hole, and they destroy every white ant in the building. Resistance there can be none, as the plethoric, slow-going white ant is as a mouse to a cat in the encounter with his active enemy, added to which the black ant is furnished with a most venomous sting, in addition to a powerful pair of mandibles. I have seen the black ants returning from their work of destruction, each carrying a slaughtered white ant in his mouth, which he devours at leisure. This is again a decided effort of reason, as the black ant arrives at the treacle without a thought of the white ant in his mind, but, upon seeing his antagonist, he despatches messengers for reinforcements, who eventually bring up the army to the "rendezvous."

Numerous instances might be cited of the presence of reasoning powers among the insect cla.s.ses, but this faculty becomes of increased interest when seen in the larger animals.

Education is both a proof and a promoter of reason in all animals.

This removes them from their natural or instinctive position, and brings forth the full development of the mental powers. This is exhibited in the performance of well-trained dogs, especially among pointers and setters. Again, in the feats performed by educated animals in the circus, where the elephant has lately endeavored to prove a want of common sense by standing on his head. Nevertheless, however absurd the trick, which man may teach the animal to perform, the very fact of their performance substantiates an amount of reason in the animal.

Monkeys, elephants and dogs are naturally endowed with a larger share of the reasoning power than other animals, which is frequently increased to a wonderful extent by education. The former, even in their wild state, are so little inferior to some natives, either in their habits or appearance, that I should feel some reluctance in denying them an almost equal share of reason; the want Of speech certainly places them below the Veddahs, but the monkeys, on the other hand, might a.s.sert a superiority by a show of tails.

Monkeys vary in intelligence according to their species, and may be taught to do almost anything. There are several varieties in Ceylon, among which the great black wanderoo, with white whiskers, is the nearest in appearance to the human race. This monkey stands upward of three feet high, and weighs about eighty pounds. He has immense muscular power, and he has also a great peculiarity in the formation of the skull, which is closely allied to that of a human being, the lower jaw and the upper being in a straight line with the forehead. In monkeys the jaws usually project. This species exists in most parts of Ceylon, but I have seen it of a larger size at Newera Ellia thin in any of the low-country districts.

Elephants are proverbially sagacious, both in their wild state and when domesticated. I have previously described the building of a dam by a tame elephant, which was an exhibition of reason hardly to be expected in any animal. They are likewise wonderfully sagacious in a wild state in preserving themselves from accidents, to which, from their bulk and immense weight, they would be particularly liable, such as the crumbling of the verge of a precipice, the insecurity of a bridge or the suffocating depth of mud in a lake.

It is the popular opinion, and I have seen it expressed in many works, that the elephant shuns rough and rocky ground, over which he moves with difficulty, and that he delights in level plains, etc., etc. This may be the case in Africa, where his favorite food, the mimosa, grows upon the plain, but in Ceylon it is directly the contrary. In this country the elephant delights in the most rugged localities; he rambles about rocky hills and mountains with a nimbleness that no one can understand without personal experience. So partial are elephants to rocky and uneven ground that should the ruins of a mountain exist in rugged fragments along a plain of low, th.o.r.n.y jungle, five chances to one would be in favor of tracking the herd to this very spot, where they would most likely be found, standing among the alleys roamed by the fragments heaped around them. It is surprising to witness the dexterity of elephants in traversing ground over which a man can pa.s.s with difficulty. I have seen places on the mountains in the neighborhood of Newera Ellia bearing the unmistakable marks of elephants where I could not have conceived it possible for such an animal to stand. On the precipitous sides of jungle-covered mountains, where the ground is so steep that a man is forced to cling to the underwood for support, the elephants still plough their irresistible course. In descending or ascending these places, the elephant a always describes a zigzag, and thus lessens the abruptness of the inclination.

Their immense weight acting on their broad feet, bordered by sharp h.o.r.n.y toes, cuts away the side of the hill at every stride and forms a level step; thus they are enabled to skirt the sides of precipitous hills and banks with comparative case. The trunk is the wonderful monitor of all danger to an elephant, from whatever cause it may proceed. This may arise from the approach of man or from the character of the country; in either case the trunk exerts its power; in one by the acute sense of smell, in the other by the combination of the sense of scent and touch. In dense jungles, where the elephant cannot see a yard before him, the sensitive trunk feels the hidden way, and when the roaring of waterfalls admonishes him of the presence of ravines and precipices, the never-failing trunk lowered upon the around keeps him advised of every inch of his path.

Nothing is more difficult than to induce a tame elephant to cross a bridge which his sagacity a.s.sures him is insecure; he will sound it with his trunk and press upon it with one foot, but he will not trust his weight if he can perceive the slightest vibration.

Their power of determining whether bogs or the mud at the bottom of tanks are deep or shallow is beyond my comprehension. Although I have seen elephants in nearly every position, I have never seen one inextricably fixed in a swamp. This is the more extraordinary as their habits induce them to frequent the most extensive mora.s.ses, deep lakes, muddy tanks and estuaries, and yet I have never seen even a young one get into a sc.r.a.pe by being overwhelmed. There appears to be a natural instinct which warns them in their choice of ground, the same as that which influences the buffalo, and in like manner guides him through his swampy haunts.

It is a grand sight to see a large herd of elephants feeding in a fine lake in broad daylight. This is seldom witnessed in these days, as the number of guns have so disturbed the elephants in Ceylon that they rarely come out to drink until late in the evening or during the night; but some time ago I had a fine view of a grand herd in a lake in the middle of the day.

I was out shooting with a great friend of mine, who is a brother-in-arms against the game of Ceylon, and than whom a better sportsman does not breathe, and we had arrived at a wild and miserable place while en route home after a jungle trip. Neither of us was feeling well; we had been for some weeks in the most unhealthy part of the country, and I was just recovering from a touch of dysentery: altogether, we were looking forward with pleasure to our return to comfortable quarters, and for the time we were tired of jungle life.

However, we arrived at a little village about sixty miles south of Batticaloa, called "Gollagangwelleweve" (p.r.o.nunciation requires practice), and a very long name it was for so small a place; but the natives insisted that a great number of elephants were in the neighborhood.
