Part 26 (1/2)
_Geckoes_.--The most familiar and attractive of the lizard cla.s.s are the _Geckoes_[1], that frequent the sitting-rooms, and being furnished with pads to each toe, they are enabled to ascend perpendicular walls and adhere to gla.s.s and ceilings. Being nocturnal in their habits, the pupil of the eye, instead of being circular as in the diurnal species, is linear and vertical like that of the cat. As soon as evening arrives, the geckoes are to be seen in every house in keen and crafty pursuit of their prey; emerging from the c.h.i.n.ks and recesses where they conceal themselves during the day, to search for insects that then retire to settle for the night. In a boudoir where the ladies of my family spent their evenings, one of these familiar and amusing little creatures had its hiding-place behind a gilt picture frame. Punctually as the candles were lighted, it made its appearance on the wall to be fed with its accustomed crumbs; and if neglected, it reiterated it sharp, quick call of _chic, chic, chit,_ till attended to. It was of a delicate gray colour, tinged with pink; and having by accident fallen on a work-table, it fled, leaving part of its tail behind it, which, however, it reproduced within less than a month. This faculty of reproduction is doubtless designed to enable the creature to escape from its a.s.sailants: the detaching of the limb is evidently its own act; and it is observable, that when reproduced, the tail generally exhibits some variation from the previous form, the diverging spines being absent, the new portion covered with small square uniform scales placed in a cross series, and the scuta below being seldom so distinct as in the original member.[2] In an officer's quarters in the fort of Colombo, a geckoe had been taught to come daily to the dinner-table, and always made its appearance along with the dessert. The family were absent for some months, during which the house underwent extensive repairs, the roof having been raised, the walls stuccoed, and the ceilings whitened. It was naturally surmised that so long a suspension of its accustomed habits would have led to the disappearance of the little lizard; but on the return of its old friends, it made its entrance as usual at their first dinner the instant the cloth was removed.

_Crocodile._--The Portuguese in India, like the Spaniards in South America, affixed the name of _lagarto_ to the huge reptiles that infested the rivers and estuaries of both continents; and to the present day the Europeans in Ceylon apply the term _alligator_ to what are in reality _crocodiles_, which literally swarm in the still waters and tanks in the low country, but rarely frequent rapid streams, and have never been found in the marshes among the hills. The differences, however, between the two, when once ascertained, are sufficiently marked, to prevent their being afterwards confounded. The head of the alligator is broader and the snout less prolonged, and the canine teeth of the under jaw, instead of being received into foramina in the upper, as in the crocodile, fit into furrows on each side of it. The legs of the alligator, too, are not denticulated, and the feet are only semi-palmate.
The following drawing exhibits a cranium of each.
[Ill.u.s.tration: SKULLS OF ALLIGATOR AND CROCODILE]
The instincts of the crocodiles in Ceylon do not lead to any variation from the habits of those found in other countries. There would appear to be two well-distinguished species found in the island, the _Eli-kimboola_[1], the Indian crocodile, inhabiting the rivers and estuaries throughout the low countries of the coasts, attaining the length of sixteen or eighteen feet, and ready to a.s.sail man when pressed by hunger; and the marsh-crocodile[2], which lives exclusively in fresh water, frequenting the tanks in the northern and central provinces, and confining its attacks to the smaller animals: in length it seldom exceeds twelve or thirteen feet. Sportsmen complain that their dogs are constantly seized by both species; and water-fowl, when shot, frequently disappear before they can be secured by the fowler.[3] It is generally believed in Ceylon that, in the case of larger animals, the crocodile abstains from devouring them till the commencement of decomposition facilitates the operation of swallowing. To a.s.sist in this, the natives a.s.sure me that the reptile contrives to fasten the carcase behind the roots of a mangrove or some other convenient tree and tears off each piece by a backward spring.

[Footnote 3: In Siam the flesh of the crocodile is sold for food in the markets and bazaars, ”Un jour je vis plus de cinquante crocodiles, pet.i.ts et grands, attaches aux colonnes de leurs maisons. Ils es vendent la chair comme on vendrait de la chair de porc, mais a bien meilleur marche.”-PALLEGOIX, _Siam_, vol. i. p. 174.]
There is another popular belief that the crocodile is exceedingly sensitive to tickling; and that it will relax its hold of a man, if he can only contrive to reach and rub with his hand the softer parts of its under side.[1] An incident indicative of some reality in this piece of folklore, once came under my own observation. One morning, about sunrise, when riding across the sandy plain near the old fort of Moeletivoe, we came suddenly upon a crocodile asleep under some bushes of the Buffalo-thorn, several hundred yards from the water. The terror of the poor wretch was extreme, when it awoke and found itself discovered and completely surrounded. It was a hideous creature, upwards of ten feet long, and evidently of prodigious strength, had it been in a condition to exert it, but consternation completely paralysed it. It started to its feet and turned round in a circle hissing and clanking its bony jaws, with its ugly green eye intently fixed upon us. On being struck with a stick, it lay perfectly quiet and apparently dead.
Presently it looked cunningly round, and made a rush towards the water, but on a second blow it lay again motionless and feigning death. We tried to rouse it, but without effect, pulled its tail, slapped its back, struck its hard scales, and teased it in every way, but all in vain; nothing would induce it to move till accidentally my son, then a boy of twelve years old, tickled it gently under the arm, and in an instant it drew the limb close to its side and turned to avoid a repet.i.tion of the experiment. Again it was touched under the other arm, and the same emotion was exhibited, the great monster twisting about like an infant to avoid being tickled. The scene was highly amusing, but the sun was rising high, and we pursued our journey to Moeletivoe, leaving the crocodile to make its way to the adjoining lake.
[Footnote 1: A native gentleman who resided for a long time at Caltura tells me that in the rivers which flow into the sea, both there and at Bentotte, crocodiles are frequently caught in corrals, formed of stakes driven into the ground in shallow water, and so constructed, that when the reptile enters to seize the bait placed within, the aperture closes behind and secures him. A professional ”crocodile charmer” then enters muttering a spell, and with one end of a stick pats the creature gently on the head for a time. The operator then boldly mounts astride upon its shoulders, and continues to soothe it with his one hand, whilst with the other he contrives to pa.s.s a rope under its body, by which it is at last dragged on sh.o.r.e. This story serves to corroborate the narrative of Mr.
Waterton and his alligator.]
The Singhalese believe that the crocodile can only move swiftly on sand or smooth clay, its feet being too tender to tread firmly on hard or stony ground. In the dry season, when the watercourses begin to fail and the tanks become exhausted, the marsh-crocodiles have occasionally been encountered in the jungle, wandering in search of water. During a severe drought in 1844, they deserted a tank near Kornegalle and traversed the town during the night, on their way to another reservoir in the suburb; two or three fell into the wells; others in their trepidation, laid eggs in the street, and some were found entangled in garden fences and killed.
Generally, however, during the extreme drought, when unable to procure their ordinary food from the drying up of the watercourses, they bury themselves in the mud, and remain in a state of torpor till released by the recurrence of rains.[1] At Arne-tivoe, in the eastern province, whilst riding across the parched bed of the tank, I was shown the recess, still bearing the form and impress of a crocodile, out of which the animal had been seen to emerge the day before. A story was also related to me of an officer attached to the department of the Surveyor-General, who, having pitched his tent in a similar position, was disturbed during the night by feeling a movement of the earth below his bed, from which on the following day a crocodile emerged, making its appearance from beneath the matting.[2]
[Footnote 1: HERODOTUS records the observations of the Egyptians that the crocodile of the Nile abstains from food during the four winter months.--_Euterpe_, lviii.]
[Footnote 2: HUMBOLDT relates a similar story as occurring at Calabazo, in Venezuela.--_Personal Narrative_, c, xvi.]
The fresh water species that inhabits the tanks is essentially cowardly in it instincts, and hastens to conceal itself on the appearance of man.
A gentleman (who told me the circ.u.mstance), when riding in the jungle, overtook a crocodile, evidently roaming in search of water. It fled to a shallow pool almost dried by the sun, and, thrusting its head into the mud till it covered up its eyes, remained unmoved in profound confidence of perfect concealment. In 1833, during the progress of the Pearl Fishery, Sir Robert Wilmot Horton employed men to drag for crocodiles in a pond which was infested by them in the immediate vicinity of Aripo.
The pool was about fifty yards in length, by ten or twelve wide, shallowing gradually to the edge, and not exceeding four or five feet at the deepest part. As the party approached the bund, from twenty to thirty reptiles, which had been basking in the sun, rose and fled to the water. A net, specially weighted so as to sink its lower edge to the bottom, was then stretched from bank to bank and swept to the further end of the pond, followed by a line of men with poles to drive the crocodiles forward: so complete was the arrangement, that no individual could have evaded the net, yet, to the astonishment of the Governor's party, not one was to be found when it was drawn on sh.o.r.e, and no means of escape for them was apparent or possible except by their descending into the mud at the bottom of the pond.
The lagoon of Batticaloa, and indeed all the still waters of this district, are remarkable for the numbers and prodigious size of the crocodiles which infest them. Their teeth are sometimes so large that the natives mount them with silver lids and use them for boxes to carry the powdered chunam, which they chew with the betel leaf. During one of my visits to the lake a crocodile was caught within a few yards of the government agent's residence, a hook having been laid the night before, baited with the entrails of a goat; and made fast, in the native fas.h.i.+on, by a bunch of fine cords, which the creature cannot gnaw asunder as it would a solid rope, since they sink into the s.p.a.ces between its teeth. The one taken was small, being only about ten or eleven feet in length, whereas they are frequently killed from fifteen to nineteen feet long. As long as it was in the water, it made strong resistance to being hauled on sh.o.r.e, carrying the canoe out into the deep channel, and occasionally raising its head above the surface, and clas.h.i.+ng its jaws together menacingly. This action has a horrid sound, as the crocodile has no fleshy lips; and it brings its teeth and the bones of the mouth together with a loud crash, like the clank of two pieces of hard wood. After playing it a little, the boatmen drew it to land, and when once fairly on the sh.o.r.e all courage and energy seemed utterly to desert it. It tried once or twice to regain the water, but at last lay motionless and perfectly helpless on the sand. It was no easy matter to kill it; a rifle ball sent diagonally through its breast had little or no effect, and even when the shot had been repeated more than once, it was as full of life as ever.[1] It feigned death and lay motionless, with its eye closed; but, on being p.r.i.c.ked with a spear, it suddenly regained all its activity. It was at last finished by a harpoon, and then opened. Its maw contained several small tortoises, and a quant.i.ty of broken bricks and gravel, taken medicinally, to promote digestion.
[Footnote 1: A remarkable instance of the vitality of the common crocodile, _C. biporcatus_, was related to me by a gentleman at Galle: he had caught on a baited hook an unusually large one, which his coolies disembowelled, the aperture in the stomach being left expanded by a stick placed across it. On returning in the afternoon with a view to secure the head, they found that the creature had crawled for some distance, and made its escape into the water.
”A curious incident occurred some years ago on the Maguruganga, a stream which flows through the Pasdun Corle, to join the Bentolle river. A man was fis.h.i.+ng seated on the branch of a tree that overhung the water; and to shelter himself from the drizzling rain, he covered his head and shoulder with a bag folded into a shape common with the natives. While in this att.i.tude, a leopard sprang upon him from the jungle, but missing its aim, seized the bag and not the man, and fell with it into the river. Here a crocodile, which had been eyeing the angler is despair, seized the leopard as it fell, and sunk with it to the bottom.”--_Letter_ from GOONE-RATNE Modliar, interpreter of the Supreme Court, 10th Jany., 1861.]
During our journeys we had numerous opportunities of observing the habits of these hideous creatures, and I am far from considering them so formidable as they are usually supposed to be. They are evidently not wantonly destructive; they act only under the influence of hunger, and even then their motions on land are awkward and ungainly, their action timid, and their whole demeanour devoid of the sagacity and courage which characterise other animals of prey.
TESTUDINATA. _Tortoise_.--Land tortoises are numerous, but present no remarkable features beyond the beautiful marking of the starred variety[1], which is common in the north-western province around Putlam and Chilaw, and is distinguished by the bright yellow rays which diversify the deep black of its dorsal s.h.i.+eld. From one of these which was kept in my garden I took a number of flat ticks (_Ixodes_), which adhere to its fleshy neck in such a position as to baffle any attempt of the animal itself to remove them; but as they are exposed to constant danger of being crushed against the plastron during the protrusion and retraction of the head, each is covered with a h.o.r.n.y case almost as resistant as the carapace of the tortoise itself. Such an adaptation of structure is scarcely less striking than that of the parasites found on the spotted lizard of Berar by Dr. Hooker, each of which presents the distinct colour of the scale to which it adheres.[2]
