After settlement commenced and people started to cultivate certain areas and to run sheep, wild pigs came to be looked upon as animals to be killed out. Drummond tells us that “they multiplied astonishingly, and enormous numbers assembled in uninhabited valleys far from the settlements. At Wangapeka Valley, in the Nelson Province, Dr. Hochstetter in 1860 saw several miles ploughed up by pigs. Their extermination was sometimes contracted for by experienced hunters, and he states that three men in twenty months, on an area of 250,000 acres, killed no fewer than twenty-five thousand pigs, and pledged themselves to kill fifteen thousand more.”
At the present time wild pigs are still common in nearly all scrub or thin bush country which is not too near settlement, and to those who like the element of danger in their hunting they afford good sport. They are usually pursued by dogs, often specially trained for the purpose, which after a time succeed in bailing up their prey. The pigs prefer to take their stand in the hollow of a tree or some such locality, and an old boar will often do considerable damage to the dogs before he is despatched. The orthodox manner is to run in and stab him; but a man without a gun has little chance if he ventures to close quarters with a bailed-up boar.
As to the food of the wild pigs, they root up the ground wherever the bracken fern (Pteris aquilina var. esculenta) is found, the starchy rhizomes furnishing abundant nutriment. They are also very fond of the thick rootstocks of spear-grasses (Aciphylla) and other umbelliferous plants, and have largely eaten out these plants over large areas. In the Chatham Islands they have been mainly responsible for exterminating the fine native forget-me-not, known as the Chatham Island lily. In the Auckland Islands they have destroyed great areas of Bulbinella and Pleurophyllum.
CHAPTER IV.
UNGULATA—DEER.
Exclusive of horses and pigs, all the other ungulates which have been introduced into New Zealand and have become established here belong to the group of ruminants, or ruminating animals. They are so called because they “ruminate”—that is, after the food has been rapidly swallowed it is forced back up the gullet and more thoroughly masticated. Belonging to this group we have to deal with deer, oxen, goats, and sheep. These animals agree in the following zoological characters: They have all two digits or toes on the feet, which are therefore popularly known as “cloven.” They have no upper incisor teeth, and the canines in the upper jaw are frequently wanting. They are furnished with horns—a very special characteristic—sometimes only on the males, sometimes on both sexes. The stomach has four chambers. The first is the large paunch, or rumen, the organ which in cattle constitutes the well-known article of food termed “tripe.” This opens into a smaller bag, the reticulum, or honeycomb bag, so called on account of the network arrangement of the folds or ridges of the mucous membrane which lines it. The reticulum opens into the psalterium, or “many-plies,” a globular organ, the interior of which is filled with folds, or laminae, which are arranged like the leaves of a book, and very close together; hence both the technical and popular names. The fourth chamber is the abomasum, or reed, sometimes called the rennet-stomach. This is the stomach proper, in which the digestion of the food is carried on, and it is the part which when removed from calves is employed for the curdling of milk.
Deer are distinguished from all other ruminants by the presence of antlers, which in all our introduced forms occur in the males only. These antlers are very interesting organs. In the commencement of the spring a pair of knobs is to be seen upon the forehead of the adult male animal. This is covered with a nearly smooth dark skin, and a scar can be detected in the middle of each, which is that left by the antler of the year before when it fell off. With advancing spring these knobs commence to grow, feel warm to the touch, and sprout out, as it were, round the scar. One branch takes a forward direction, whilst a second and larger one makes its way backward. These become in the fully-formed antler the brow-antler and the main beam. As long as the antler, which is composed of genuine bone of very dense texture, is increasing in size it is covered with the same warm, black skin as is the knob from which it sprang, and as this skin is covered with short, fine, close-set hair it has received the name of the “velvet.” It is this velvet which secretes the bony texture of the antler from its inner surface; therefore any mishap to it injures the growth of the antler in the part affected. The animals, therefore, during the time they are “in velvet” are more than usually careful to protect their heads, and are inoffensive even to strangers. When the antlers have ceased to grow, the velvet dries up, and the deer rub their horns against any neighbouring trees and force them into the soft earth until the membrane is quite rubbed off. Up to this time they have lived a kind of solitary existence, but now they go forth in their full vigour, seek out their future mates, and fight any other stags which dare to dispute their ascendancy.
The desire to stock the mountain country of New Zealand with large game, so that the Briton’s delight in going out to kill something might be satisfied, has led to the introduction of no fewer than nine kinds of deer, in addition to other large animals. Of these, four species—fallow deer, red deer, sambur deer, and white-tailed deer—have established themselves in different parts of the country, and are included among the animals to shoot which licenses are now issued. By law they are strictly preserved, but much poaching has always been and still is done. At the same time, it must be remembered that the poaching is chiefly done by two classes of people—namely, by residents in the neighbourhood of the districts where the game abound, and by mere pot-hunters. For the first class it may be said that many farmers, who take no special interest in acclimatization work or in so-called “sport,” who were not consulted in any way on the subject, and who probably object to seeing the undesirable game laws of the Old Country being reintroduced here for the sake of a few wealthy people who are willing to pay a price for the privilege of killing deer, naturally resent the incursions of animals which ignore or break down their fences, harass their stock, and eat their hay and turnips. Therefore some of this destruction of imported game takes the form of reprisals for injury done to crops, fences, and stock. There is practically little or no poaching, such as is characterized by the name in the Mother-country, done on the property of private individuals, and consequently destruction of game in New Zealand is not looked upon as a heinous offence, as were breaches of the iniquitous game laws of Britain in pre-war days. The game in New Zealand is the property either of the State or of the acclimatization societies, and public opinion on the subject of its destruction is lax in comparison with what it is in countries where game is looked upon as something reserved for and sacred to the sporting instincts of a small, self-constituted, and select class. Still, a very fair measure of protection is ensured to the animals, and they have increased in many districts where they have been liberated. It has been recognized, too, that a wealthy class of tourists can be induced to visit the country if, in addition to scenic attractions, there can be added those things which appeal to the sporting instincts of humanity. This has led the Government of the Dominion in recent years to devote some attention to the subject of introducing various additional kinds of big game to those already brought in by the acclimatization societies.
