Part 16 (1/2)
[Footnote 2: In the Museum of the College of Surgeons, London (No. 4362 A), there is a cranium of a jackal which exhibits this strange osseous process on the super-occipital; and I have placed along with it a specimen of the h.o.r.n.y sheath, which was presented to me by Mr.
Lavalliere, the district judge of Kandy.]
Jackals are subject to hydrophobia, and instances are frequent of cattle being bitten by them and dying in consequence.
_The Mongoos_.--Of the Mongoos or Ichneumons five species have been described; and one which frequents the hills near Neuera-ellia[1], is so remarkable from its bushy fur, that the invalid soldiers in the sanatarium, to whom it is familiar, call it the ”Ceylon Badger.” I have found universally that the natives of Ceylon attach no credit to the European story of the Mongoos (_H. griseus_) resorting to some plant, which no one has yet succeeded in identifying, as an antidote against the bite of the venomous serpents on which it preys. There is no doubt that in its conflicts with the cobra de capello and other poisonous snakes, which it attacks with as little hesitation as the harmless ones, it may be seen occasionally to retreat, and even to retire into the jungle, and, it is added, to eat some vegetable; but a gentleman who has been a frequent observer of its exploits, a.s.sures me that most usually the herb it resorted to was gra.s.s; and if this were not at hand, almost any other that grew near seemed equally acceptable. Hence has probably arisen the long list of plants; such as the _Ophioxylon serpentinum_ and _Ophiorhiza mungos_, the _Aristolochia Indica_, the _Mimosa octandru_, and others, each of which has been a.s.serted to be the ichneumon's specific; whilst their multiplicity is demonstrative of the non-existence of any one in particular to which the animal resorts for an antidote. Were there any truth in the tale as regards the mongoos, it would be difficult to understand, why other creatures, such as the secretary bird and the falcon, which equally destroy serpents, should be left defenceless, and the ichneumon alone provided with a prophylactic.
Besides, were the ichneumon inspired by that courage which would result from the consciousness of security, it would be so indifferent to the bite of the serpent, that we might conclude that, both in its approaches and its a.s.sault, it would be utterly careless as to the precise mode of its attack. Such, however, is far from being the case; and next to its audacity, nothing is more surprising than the adroitness with which it escapes the spring of the snake under a due sense of danger, and the cunning with which it makes its arrangements to leap upon the back and fasten its teeth in the head of the cobra. It is this display of instinctive ingenuity that Lucan[2] celebrates where he paints the ichneumon diverting the attention of the asp, by the motion of his bushy tale, and then seizing it in the midst of its confusion.
[Footnote 1: _Herpestes vitticollis_. Mr. W. ELLIOTT, in his _Catalogue of Mammalia found in the Southern Maharata Country_, Madras, 1840, says, that ”One specimen of this Herpestes was procured by accident in the Ghat forests in 1829, and is now deposited in the British Museum; it is very rare, inhabiting only the thickest woods, and its habits are very little known,” p. 9. In Ceylon, it is comparatively common.]
[Footnote 2: The pa.s.sage in Lucan is a versification of the same narrative related by Pliny, lib. viii. ch. 35; and aelian, lib. iii. ch.
22.]
”Aspidas ut Pharias cauda solertior hostis Ludit, et iratas incerta provocat umbra: Obliquusque caput vanas serpentis in auras Effusae toto comprendit guttura morsu Letiferam citra saniem; tune irrita pestis Exprimitur, faucesque fluunt pereunte veneno.”
_Pharsalia_, lib. iv. v. 729.
The mystery of the mongoos and its antidote has been referred to the supposition that there may be some peculiarity in its organisation which renders it _proof against_ the poison of the serpent. It remains for future investigation to determine how far this conjecture is founded in truth; and whether in the blood of the mongoos there exists any element or quality which acts as a prophylactic. Such exceptional provisions are not without precedent in the animal oeconomy: the hornbill feeds with impunity on the deadly fruit of the strychnos; the milky juice of some species of euphorbia, which is harmless to oxen, is invariably fatal to the zebra; and the tsetse fly, the pest of South Africa, whose bite is mortal to the ox, the dog, and the horse, is harmless to man and the untamed creatures of the forest.[1]
[Footnote 1: Dr. LIVINGSTONE, _Tour in S. Africa_, p. 80. Is it a fact that in America, pigs extirpate the rattlesnakes with impunity?]
The Singhalese distinguish one species of mongoos, which they designate ”_Hotambeya_,” and which they a.s.sert never preys upon serpents. A writer in the _Ceylon Miscellany_ mentions, that they are often to be seen ”crossing rivers and frequenting mud-brooks near Chilaw; the adjacent thickets affording them shelter, and their food consisting of aquatic reptiles, crabs, and mollusca.”[1]
[Footnote 1: This is possibly the ”musbilai” or mouse-cat of Behar, which preys upon birds and fish. Could it be the Urva of the Nepalese (_Urva cancrivora_, Hodgson), which Mr. Hodgson describes as dwelling in burrows, and being carnivorous and ranivorous?--Vide _Journ. As. Soc.
Beng._, vol. vi. p. 56.]
IV. RODENTIA. _Squirrels_.--Smaller animals in great numbers enliven the forests and lowland plains with their graceful movements. Squirrels[1], of which there are a great variety, make their shrill metallic call heard at early morning in the woods, and when sounding their note of warning on the approach of a civet or a tree-snake, the ears tingle with the loud trill of defiance, which rings as clear and rapid as the running down of an alarum, and is instantly caught up and re-echoed from every side by their terrified playmates.
[Footnote 1: Of two kinds which frequent the mountains, one which is peculiar to Ceylon was discovered by Mr. Edgar L. Layard, who has done me the honour to call it the _Sciurus Tennentii_. Its dimensions are large, measuring upwards of two feet from head to tail. It is distinguished from the _S. macrurus_ by the predominant black colour of the upper surface of the body, with the exception of a rusty spot at the base of the ears.]
One of the largest, belonging to a closely allied subgenus, is known as the ”Flying Squirrel,”[1] from its being a.s.sisted in its prodigious leaps from tree to tree, by the parachute formed by the skin of the flanks, which on the extension of the limbs front and rear, is laterally expanded from foot to foot. Thus buoyed up in its descent, the spring which it is enabled to make from one lofty tree to another resembles the flight of a bird rather than the bound of a quadruped. Of these pretty creatures there are two species, one common to Ceylon and India, the other (_Sciuropterus Layardii_, Kelaart) is peculiar to the island, and is by far the most beautiful of the family.
[Footnote 1: Pteromys oral., _Tickel_. P. petaurista, _Pallas_.]
_Rats_.--Among the multifarious inhabitants to which the forest affords at once a home and provender is the tree rat[1], which forms its nest on the branches, and by turns makes its visits to the dwellings of the natives, frequenting the ceilings in preference to the lower parts of houses. Here it is incessantly followed by the rat-snake[2], whose domestication is encouraged by the native servants, in consideration of its services in destroying vermin. I had one day an opportunity of surprising a snake which had just seized on a rat of this description, and of covering it suddenly with a gla.s.s shade, before it had time to swallow its prey. The serpent, which appeared stunned by its own capture, allowed the rat to escape from its jaws, which cowered at one side of the gla.s.s in the most pitiable state of trembling terror. The two were left alone for some moments, and on my return to them the snake was as before in the same att.i.tude of sullen stupor. On setting them at liberty, the rat bounded towards the nearest fence; but quick as lightning it was followed by its pursuer, which seized it before it could gain the hedge, through which I saw the snake glide with its victim in its jaws.
[Footnote 1: There are two species of the tree rat in Ceylon: M.
rufescens, _Gray_; (M. flavescens; _Elliot_;) and Mus nemoralis, _Blyth_.]
[Footnote 2: Coryphodon Blumenbachii.]
Another indigenous variety of the rat is that which made its appearance for the first time in the coffee plantations on the Kandyan hills in the year 1847, and in such swarms does it infest them, that as many as a thousand have been killed in a single day on one estate. In order to reach the buds and blossoms of the coffee, it cuts such slender branches, as would not sustain its weight, and feeds as they fall to the ground; and so delicate and sharp are its incisors, that the twigs thus destroyed are detached by as clean a cut as if severed with a knife. The coffee-rat[1] is an insular variety of the _Mus hirsutus_ of W. Elliot, found in Southern India. They inhabit the forests, making their nests among the roots of the trees, and like the lemmings of Norway and Lapland, they migrate in vast numbers on the occurrence of a scarcity of their ordinary food. The Malabar coolies are so fond of their flesh, that they evince a preference for those districts in which the coffee plantations are subject to these incursions, where they fry the rats in oil, or convert them into curry.
[Footnote 1: Golunda Ellioti, _Gray_.]
_Bandicoot_.--Another favourite article of food with the coolies is the pig-rat or Bandicoot[1], which attains on those hills the weight of two or three pounds, and grows to nearly the length of two feet. As it feeds on grain and roots, its flesh is said to be delicate, and much resembling young pork. Its nests, when rifled, are frequently found to contain considerable quant.i.ties of rice, stored up against the dry season.
[Footnote 1: Mus bandicota, _Beckst_. The English term bandicoot is a corruption of the Telinga name _pandikoku_, literally _pig-rat_.]
_Porcupine_.--The Porcupine[1] is another of the _rodentia_ which has drawn down upon itself the hostility of the planters, from its destruction of the young coco-nut palms, to which it is a pernicious and persevering, but withal so crafty, a visitor, that it is with difficulty any trap can be so disguised, or any bait made so alluring, as to lead to its capture. The usual expedient is to place some of its favourite food at the extremity of a trench, so narrow as to prevent the porcupine turning, whilst the direction of his quills effectually bars his retreat. On a newly planted coco-nut tope, at Hang-welle, within a few miles of Colombo, I have heard of as many as twenty-seven being thus captured in a single night; but such success is rare. The more ordinary expedient is to smoke them out by burning straw at the apertures of their burrows. The flesh is esteemed a delicacy in Ceylon, and in consistency, colour, and flavour, it very much resembles that of a young pig.
