The matter indeed is becoming one of very great danger to the welfare of the colony; so much so, that a special Commission has been appointed by the government to inquire into the subject. Without quoting an array of figures to prove the harm which has been wrought in a few short years, it may truly be said that large tracts of rich pasture-land have been converted into a veritable wilderness. The sheep-farmers and cattle-raisers find their occupation is becoming impossible. The yield of wool is falling off fifty and sixty per cent. in quantity, while its quality is deteriorating. The lack of food has caused many farmers who used to kill two thousand five hundred animals out of a stock of sixteen thousand, to reduce their stock to a few hundreds, hardly any of which are fit to be killed. The number of lambs in proportion to the ewes kept has fallen from sixty-five or seventy per cent. to in some cases twelve and a half per cent.
It must not be imagined that no efforts have been made to keep down the pests. Large numbers of men and dogs are employed specially for the purpose of shooting and trapping the rabbits. In one run, where scarcely a rabbit was to be seen three years ago, there are now sixteen men and one hundred and twenty dogs employed; costing the lessee twopence for each rabbit-skin brought in, and ten shillings per week for each man, besides the expense of keep and powder and shot. And the numbers killed are enormous. On this run, says the official Report, the average number of rabbits killed weekly is between four and five thousand; and though thirty-six thousand were killed in 1875, yet the report is that there is no appreciable decrease. On another run, close on sixteen thousand rabbits were killed during the first three months of the year 1876 at a cost of twopence a skin. On a third, the expense each week averages twenty-seven pounds; and fifty thousand rabbits were killed in the first four months of 1876. On a fourth run, nine men are employed with sixty dogs, killing at the rate of two thousand per week.
One landowner, in despair of reclaiming a large tract of land infested by these destructive rodents, inclosed an area of ten thousand acres with a solid masonry wall, the foundations of which were dug down to the hard rock, to prevent any chance of the rabbits burrowing under it. Seven years were occupied in erecting this 'great wall'--an undertaking comparable with the ancient walls built in the north of England to keep out the Picts and Scots--and thirty-five thousand pounds were expended in the course of the work. What a happy family the countless myriads of rabbits in that area must be, if they have not already starved themselves to death! This heroic remedy was adopted not only in New Zealand but in Victoria; for others of our Australasian colonies besides New Zealand have (as we have already shewn in the former article) suffered from a scourge of conies. Tasmania and Victoria and South Australia have been made the victims of a misplaced confidence in the virtues of the rabbit. The chief inspector of sheep in Tasmania, writing in 1875, stated that at that time the rabbits were consuming sufficient food to support two hundred and fifty thousand sheep, and thus causing a direct annual loss to the colony of sixty-two thousand pounds, without taking into account the money expended in keeping them down. In all these colonies special laws have been made for the purpose of dealing with these troublesome inhabitants. The main feature of the system adopted is that trustees are appointed, who have power to levy a rate on the lands in 'proclaimed districts,' the proceeds of which are expended in a specially organised campaign against the rabbits; and generally good results have followed these operations. There are runs in Tasmania on which a good shot could bag three to four hundred bunnies in a day six years ago, but where half-a-dozen could not now be seen in the same time.
