THE Future.

Looking forward to the future, one is tempted to ask whether there is any prospect that the evil will ever be checked. Reafforesting and the protection of river-banks are, of course, the two remedies that are most needed. The former is being undertaken to a certain extent by the Government; but the area on which it is possible to operate is quite insignificant compared to the extent of land that is suffering; while, in regard to the protection of river-banks, it is an art that is not yet understood in this country, and one which, moreover, would be far too costly to undertake on any general scale, though a good deal might be done in special cases, such as that of the Ohinemuri River and the Lower Waihou. Speaking broadly, the trouble must go on and increase in the open country. There is no finality about a landslip, and for many years to come the rivers will wander at will over the alluvial plains, while erosion and silting will go on as before. Neither is there any hope that the residue of the standing forest will remain intact. Land must be provided for settlement, and so long as there is a demand for timber the trees will be cut down; and once the timber-trees have been removed the rest of the bush, as already shown,

will quickly disappear. In a very few years the kauri and the totara will be exhausted, and the rimu and the kahikatea, the black-birch, and the matai will not last for ever. At the present moment, owing to the rising price of timber, trees that a few years ago would have been considered inaccessible are being brought to market, while bushes that would have been looked upon as worthless in the past are now being worked for anything that will cut up into a plank or a piece of scantling. All this tends to the more rapid denundation of the country, followed by the climatic and topographical changes already described; and, as in America, in the Scandinavian Peninsula, and elsewhere, as the pulp industry follows the sawmill, once the larger timber has become exhausted, so doubtless it will be before long in New Zealand, and then the deforestation, with all its disastrous consequences, will become more rapid and complete.

It is satisfactory to notice that there is a dawning improvement in public opinion on this matter. Several well-timed articles have lately appeared in the newspapers of the Dominion, amongst which was a most thoughtful and logical exposition of the subject in a series of papers by Mr. J. P. Grossman in the New Zealand Graphic, since reprinted under the title of “The Evils of Deforestation.” The Government also seems to be waking up to a sense of the importance of conserving some of the remnant of the forest before it is too late. And quite recently the Under-Secretary for Lands, Mr. W. C. Kensington, in reply to a criticism of the policy of the Department in withholding from settlement certain lands on the Wanganui watershed, very wisely pointed out that, unless the forest in that locality were rigidly protected, the famous “New Zealand Rhine,” not only as a beautyspot but as a navigable river, would soon be a thing of the past. While all this is very satisfactory, it must be remembered, as I pointed out in a former paper, that reservation must be more than reservation on the map. To be of any practical use reservation must be made with a barbed-wire fence, as, if cattle and pigs are allowed to enter, the fire will follow sooner or later, and the end will begin. The folly of neglecting this simple expedient has been amply exemplified in the Taranaki Mountain reserve, the Waitakerei Ranges, and in the Waipoua Kauri Forest, where much of the bush has been destroyed.

But while we have a right to demand from the Government such a protection of the public interest as is involved in the conservation of such portions of the existing forest as may be consistent with the interests of settlement, as well as in the reafforestation of the open land when such a measure may be practical and desirable, a great deal of good might be effected by private enterprise. In the neighbourhood of Melbourne it has been noticed that the hot winds and dust-storms, that are such a disagreeable feature of the Victorian climate, have lost much of their fierceness since the suburbs have been planted; while in the Waikato all old settlers are agreed that since the plantations of Pinus insignis, poplars, &c., which are so conspicuous in that district, have grown up the frosts have of late years not been nearly so severe as they were.

If legislation is to be invoked in this matter it might be well to consider the advisability of making it compulsory, in certain areas, for every landowner to plant and keep under timber a certain percentage of his holding. Such a measure would not only be of incalculable benefit to the country at large, but would be of very material advantage to the settler himself, as experiment has already proved that there is no more paying crop than a plantation of timber-trees.

In endeavouring to demonstrate the effect of the wholesale destruction of the New Zealand bush on the climate and on the topography of the country, and to show that these effects are far more productive of evil than of good, I do not pretend to have started any new or original theory. The science of forestry, the influence of standing timber on climate, and the action of running water are perfectly well understood in many parts of the world. In France, Germany, Austria, Switzerland, Sweden, and Norway, and many other European countries, stringent regulations on the subject are in operation, and have long since justified the wisdom of their enactment. Even in the United States of America it is coming home to the people that the “forest primeval” is neither boundless nor inexhaustible. Congress has already wisely provided for the setting-aside out of the public domain some 70,000 square miles of valuable forest land, with the view of protecting the streams and perpetuating the timber-supply in the western States and Territories; while at the present moment a scheme is under consideration for acquiring by purchase the whole of the Southern Appalachian Mountains, a district containing no less than 12,000 square miles, or over 7,000,000 acres, in one block, for a forest reserve. It would be well if we in New Zealand were to follow the example of other countries. But so long as we see the stream of logs coming down the railway or coming up the harbour, so long as the distant hills appear to be clothed with bush, and so long as our timber companies are paying a good dividend it is probable that no very earnest or systematic action will be undertaken. We fail to notice that the logs are getting smaller and smaller all the time, and we do not perceive the gaps in the sky-line of the hills, a sure indication that the bush is already far on its way to destruction.

It is my earnest hope that by a plain statement of the case, based on the experience and observation of over forty years, spent more or less in the bush, public attention may be aroused to a sense of our loss before the loss has become altogether irretrievable.

In concluding, I should like to record my grateful thanks to Mr. James Nicholson, of Waihi, for much valuable information on some of the subjects treated.
