"To give you an idea of the slaughter of rabbits in New Zealand, let me say that ten millions of rabbit-skins are exported every year, but the value of these skins is very little compared with the damage which the animals have caused. The latest official reports show that the nuisance is checked in some localities, but there are yet many millions of rabbits to be disposed of. In England and other countries foxes, wolves, weasels, and other noxious animals keep down the number of rabbits, but here, where they have no natural enemies, the country suffers terribly. Many a sheep-farmer has been ruined by the total destruction of his pasturage, and the loss to the colony may be reckoned by millions of dollars.
REDUCING THE RABBIT POPULATION.
"Australia and Tasmania are equally afflicted by rabbits," the gentleman continued, "which were introduced into those countries from New Zealand for the same reasons that they were introduced here. Millions of pounds sterling would not compensate for their ravages, and the public and private expenditure for their destruction has already mounted into those figures. Dogs, ferrets, poison, trapping, drowning, and every other known means have been tried to reduce them, but without success. Occasionally the whole population turns out for a rabbit 'battue,' in which many thousands of the animals are killed. The owners of sheep and cattle runs have built hundreds of miles of rabbit-fences, and the colonial governments have done likewise; the fences stop the progress of the vermin for a time, but after a while they manage to burrow beneath them and come up on the other side, and so the fences are not effective to prevent the spread of the pest."
"Haven't I read about their being killed by forcing noxious gases into their warrens?" one of the boys asked.
"Yes," was the reply, "that has been done, but the machines for making and using the gas are costly and cumbersome, and in rocky regions they do not work satisfactorily.
"Recently the Government of New South Wales has offered a reward of twenty-five thousand pounds to any one who will devise a successful system of destroying rabbits, provided it is not dangerous to live-stock and to human beings. The attention of the scientific world is directed to the subject, and perhaps the remedy may be found. Pasteur, the celebrated French scientist, has proposed to inoculate a few rabbits with chicken-cholera and allow them to run among their kindred, and thus introduce the disease. He says it is harmless to all animals, with the exception of rabbits and chickens, and believes that the whole rabbit population could in this way be killed off, though at the same time our domestic fowls would be killed too, unless they were carefully shut up. We could afford to lose every fowl in the southern hemisphere if we could only get rid of this great pest of rabbits; but it will be necessary to proceed very cautiously, lest our sheep and cattle should suffer."
The youths had a realizing sense of the extent of this pest in the Australasian colonies, when they saw on several occasions whole hillsides and stretches of plain that seemed to be in motion, so thickly was the ground covered with rabbits. Mr. Abbott further told them that Dunedin and other cities had a regular exchange, or market, for rabbit-skins, where dealings were conducted as in the grain, wool, and other exchanges. The skins mostly find their way to London, Paris, Berlin, Vienna, and Naples, where they are made into "kid" gloves of the lower grades. They are also made into hats, and it is hoped that they may be found useful for other purposes, so as to make profitable the wholesale slaughter of the animals on whose backs they grow.[8]
