upon them, and there remains; not only until the eggs are hatched, but for a long time afterwards – in fact, until the young are nearly fledged and able to take care of themselves. In order that she may be protected during the period of her incubation against weasels, polecats, ichneumons, and all such vermin, a design exhibiting either wonderful instinct or sagacity, is carried into execution by the male. As soon as his mate has squatted upon her eggs, he goes to work at the masonic art; and using his great horned mandibles, first as a hod, and afterwards as a trowel, he walls up the entrance to the nest – leaving an aperture just large enough to be filled up by the beak of the female. The material employed by him for this purpose is a kind of agglutinated mud, which he procures from the neighbouring watercourse or quagmire, and somewhat similar to that used by the common house-swallow for constructing its peculiar nest. When dried, this mud becomes exceedingly hard – bidding defiance to the teeth and claws of all would-be intruders, whether bird or quadruped; and with the horny beak of the old hen projected outward, and quite filling up the aperture, even the slippery tree-snake cannot find room enough to squeeze his body through. The female, thus free from all fear of being molested, quietly continues her incubation!

      When Ossaroo had got thus far with his explanation, Caspar interrupted him with a query.

      “What!” said he, “sit all the time – for weeks, I suppose – without ever coming out – without taking an airing? And how does she get her food?”

      As Caspar put this question, and before Ossaroo had time to answer, a noise reached their ears which appeared to proceed from the sky above them. It was a noise well calculated to inspire terror in those who had never before heard it, or did not know what was causing it. It was a sort of fluttering, clattering sound, or rather a series of sounds, resembling the quickly repeated gusts of a violent storm.

      The moment Ossaroo heard it, he knew what it was; and instead of giving a direct answer to Caspar’s question, he simply said —

      “Wait a bit, sahib. Here come old cockee horneebill; he show you how de hen getee her food.”

      The words had scarcely passed from the lips of the shikaree, when the cause of that singular noise became known to his companions. The maker of it appeared before them in the form of a great bird, that with a strong flapping of its wings flew past the tree in which they were seated, towards that which contained the nest.

      In an instant afterwards, it was seen resting on a spur-like projection of the trunk, just below the aperture; and it needed not Ossaroo to tell them that it was the cock hornbill that had there alighted. The large beak – the tip of it resembling that which they had already seen sticking out of the hole, and which was once more visible and in motion – surmounted by an immense helmet-like protuberance, rising upon the crown, and running several inches along the top of the upper mandible, which might have been taken for a second beak – this singular appendage could belong to no other bird than the hornbill.

      Chapter Fifteen.

      The hornbill

      Karl, although he had never seen one of these birds alive, had yet examined stuffed specimens of them in museums, and he had no difficulty in recognising the bird. He was able even to identify the species, for there are many species of hornbill, known under the generic name, Bucerus. That before their eyes was the Bucerus rhinoceros, or “rhinoceros hornbill,” called also the “topau,” and sometimes the “horned Indian raven,” from a sort of resemblance which it bears both in shape and habits to the well-known bird of this name.

      Ossaroo had not exaggerated the size of these birds when he compared it to that of a goose. On the contrary, he had rather moderated the dimensions: for the one in question looked much larger than either goose or gander. It was rather more than three feet in length – reckoning from the tip of its tail to the point of its curving beak, which of itself was nearly a foot long! Its colour was black above, and yellowish-white underneath, the tail feathers being a clear white, with a broad black band crossing them near the middle. Its bill, like that of its mate already observed, was of a yellowish-white, the upper mandible being reddish around the base, while the casque-like protuberance exhibited a mottled surface of white and black.

      Ossaroo had to tell them pretty nearly all he knew in relation to this curious bird; for although there are several species of hornbills natives of India, it is by no means a common creature, even at home in its own country.

      Karl could have told them much more about its species and habits, and no doubt he would have done so had they been otherwise engaged. But situated as they were, with an angry elephant besieging them in the tree, and now for a while interested in observing the movements of the bird itself, Karl was in no humour to deliver an ornithological lecture. He might have told them that ornithologists have differed much about the classification of the hornbill – some of them placing it among the toucans, while others assert that it belongs to the crow family. Its immense beak – out of all proportion to its body – is not the only point of resemblance it bears to the toucans. Like them, it flings its food into the air, catching and swallowing it as it comes down. Unlike the toucans, however, it cannot climb trees, and is therefore not of the Scansorial order. It is said to be omnivorous in its food; and in this it resembles the crows and ravens: but, indeed, as already stated, there are many species of hornbills, and the habits of the different kinds, by no means uniform or alike, have been confounded by most writers. There are species in Africa, others in India and the Indian islands, and New Guinea is known to have one or two distinct species of its own. All these differ not only in size, colour, shape of their beak, and the protuberance that surmounts it; but also in the kind of food which they live upon. For instance, the African hornbills, and one or more of the Asiatic species, are carnivorous, and some even carrion-eaters. These are filthy birds, their flesh and feathers smelling rank as those of vultures. On the other hand, there is a species in the Indian islands – the Moluccas more particularly – whose sole food is the nutmeg, which gives to its flesh an exquisite aromatic flavour, causing it to be much relished at the tables of Oriental epicures. The bill of this species after a certain time appears with a number of grooves or furrows in it. As these furrows are observed only on the beaks of the old birds, the Dutch colonists established in the Moluccas believe them to indicate their age, each wrinkle standing for a year. Hence the hornbill has obtained among the colonists the name of Yerrvogel (year bird).

      Karl, as I have said, was acquainted with all these facts in the natural history of the hornbill; but just then he did not think of making them known to his companions – all three being too much occupied in watching the movements of the male bird. It was evident that he was not one of the vegetable feeders: for on his alighting they could see hanging from his beak a long cylindrical object, which they were able to identify as a portion – the head and part of the body – of a dead snake. It was equally evident that his mate was not accustomed to a vegetable diet: for from the way in which he was manoeuvring, the spectators saw that the mutilated reptile was intended for her. No doubt it was her dinner, for it had now got to that hour of the day.

      She was not to be kept waiting any longer. Almost on the instant her provider alighted on the projecting spur, with a toss of his head he jerked the piece of snake up into the air, and then caught it as it came down again – not with the intention to swallow it, but only to get a better grip, in order that he might deliver it the more adroitly into the mandibles of his mate – now protruding through the aperture, and opened to receive it.

      In another instant the savoury morsel was transferred from the beak of the male to that of the female; and then the ivory forceps of the latter, with the snake held tightly between them, disappeared within the cavity.

      The old cock stayed not a moment longer upon the tree. He had served his mate with her dinner, and perhaps he had yet to bring on the dessert. Whether or not, he rose immediately afterwards into the air, with the same clangorous clapping of his wings; but this time the noise was accompanied by the clattering of his horny mandibles, like a pair of castanets, causing a sound not only singular, but, if heard by strangers, calculated to beget within them a considerable feeling of alarm.
