These faculties they display in a high degree in their hunting expeditions, especially in the northern portions of the island, where they are found in the greatest numbers. In these districts, where the wide sandy plains are thinly covered with brushwood, the face of the country is diversified by patches of thick jungle and detached groups of trees, that form insulated groves and topes. At dusk, or after nightfall, a pack of jackals, having watched a hare or a small deer take refuge in one of these retreats, immediately surround it on all sides; and having stationed a few to watch the path by which the game entered, the leader commences the attack by raising the unearthly cry peculiar to their race, and which resembles the sound _okkay!_ loudly and rapidly repeated. The whole party then rush into the jungle, and drive out the victim, which generally falls into the ambush previously laid to entrap it. A native gentleman[1], who had favourable opportunities of observing the movements of these animals, informed me, that when a jackal has brought down his game and killed it, his first impulse is to hide it in the nearest jungle, whence he issues with an air of easy indifference to observe whether anything more powerful than himself may be at hand, from which he might encounter the risk of being despoiled of his capture. If the coast be clear, he returns to the concealed carcase, and carries it away, followed by his companions. But if a man be in sight, or any other animal to be avoided, my informant has seen the jackal seize a coco-nut husk in his mouth, or any similar substance, and fly at full speed, as if eager to carry off his pretended prize, returning for the real booty at some more convenient season. [Footnote 1: Mr. D. de Silva Gooneratné.] They are subject to hydrophobia, and instances are frequent in Ceylon of cattle being bitten by them and dying in consequence. [Illustration: JACKAL'S SKULL AND HORN] An excrescence is sometimes found on the head of the jackal, consisting of a small horny cone about half an inch in length, and concealed by a tuft of hair. This the natives call _narrie-comboo_; and they aver that this "Jackal's Horn" only grows on the head of the leader of the pack.[1] Both the Singhalese and the Tamils regard it as a talisman, and believe that its fortunate possessor can command by its instrumentality the realisation of every wish, and that if stolen or lost by him, it will invariably return of its own accord. Those who have jewels to conceal rest in perfect security if along with them they can deposit a narri-comboo, fully convinced that its presence is an effectual safeguard against robbers. [Footnote 1: 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 horny sheath, which was presented to me by Mr. Lavalliere, the late district judge of Kandy.]
