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[2841], 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 assail man when pressed by hunger; and the marsh-crocodile[2842], 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.[2843] 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 assist in this, the natives assure 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.
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.[2844] 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 repetition 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.
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.[2861] 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.[2862]
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 circumstance), 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 shore, 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 fashion, by a bunch of fine cords, which the creature cannot gnaw asunder as it would a solid rope, since they sink into the spaces 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 shore, carrying the canoe out into the deep channel, and occasionally raising its head above the surface, and clashing 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 shore 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.[2881] It feigned death and lay motionless, with its eye closed; but, on being pricked 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 quantity of broken bricks and gravel, taken medicinally, to promote digestion.
