Now, the question is, How far will this destruction extend, and what will be the ultimate condition of the portion that escapes? It may be broadly stated: (I) That below a certain altitude, varying according to locality, climate, and aspect, wherever the soil is fairly fertile, the bush once removed will never reappear; (2) that in elevated and barren country, especially in cold and moist situations, the bush has a fair prospect of remaining practically in its virgin condition; (3) while between the two the battle will be fought with varying success, and that, though considerable portions will escape extinction, they will undergo a gradual but very complete alteration in character and appearance. Each of these propositions may be considered in detail:—
(1.) In open fertile situations, under favourable climatic conditions, all burnt land is soon covered with a thick “sole” of grass, in which even were a seedling tree to spring up it would be immediately eaten or trodden down. In new clearings in this class of country a few trees will probably survive for a time in the imperfectly burnt patches, or a light second growth come up amongst the stumps and logs in spots beyond the reach of cattle. But unless permanently protected by some inequality of the ground, as in the case of steep ravines, river-banks, &c., they will gradually disappear as the animals push their way through the rotting timber, and as the fire once more overruns the place, which it is sure to do so long as any considerable portion of the dead stuff remains. This is what may be seen in all its stages on any bush farm, and is taking place on a large scale throughout the districts of Taranaki, Manawatu, parts of the Wellington and Nelson Provinces, and the Akaroa Peninsula, where practically the native bush is a thing of the past, and where in a few years, when the stumps and logs have disappeared, the country will be as clear and open as the Napier or Canterbury Plains.

(2.) In high, mountainous country, especially in regions where the climate for the greater part of the year is cold and wet, the floor of the bush, instead of being covered with an esculent growth of underwood, is chiefly coated with a layer of damp moss; so that there is not much to attract the wandering beasts or to feed a fire even in the driest seasons. In such country the conditions of soil and climate preclude the possibility of settlement, while the trees are generally too small or too difficult of access to be of much economic value from the timber-getter's point of view. This favourable state of things obtains in all high altitudes, but especially in the mountain districts of the south and west; and here it is satisfactory to think that Nature will manage to hold her own, and that the bush will remain in perpetuity to form the appropriate setting of the wild and romantic scenery.
(3.) Scattered throughout the two Islands are numerous portions of country where the contending forces are pretty equally balanced—the cattle and the fire doing a considerable amount of damage, while Nature displays a marvellous power of resistance and recuperation. This class of country occurs principally in hilly and broken districts of moderate elevation, where the soil is of too poor a quality to take grass readily. It is frequently of large extent, and often abounds in scenery of great variety and beauty. A general feature will be at once remarked: that the bush is chiefly confined to the gullies, while the sharp crests and rounded backs of the ranges are covered with fern or scrub tea-tree. The reason of this is obvious. The fires which swept over the dry and exposed surfaces naturally died out when they reached the damp and sheltered hollows. Occasionally, extensive areas occur where even the most exposed ranges still retain their virgin mantle. This happens when some natural obstacle—as a river, a deep ravine, or a rocky cliff—- has prevented the flames from getting a start on the block. Such wooded areas are not uncommon in localities where the soil is too poor and the surface too broken to make farming a profitable undertaking, or where the bushman has not yet made his appearance. Sooner or later, however, a road or telegraph-line is cut through the thick of the bush, or a settlement laid out in the vicinity, when the balance is upset, and the whole aspect of things rapidly alters; as, once the fires find an entrance, they burn year after year, gradually denuding the most exposed spots, and continuing on until they are once more met by some natural obstacle. A notable instance of this may be seen in the case of the Puhipuhi State Forest, between Whangarei and the Bay of Islands, a few years ago the most extensive kauri bush in the country, and estimated to contain some 400,000,000 ft. of that valuable timber. From mistaken

economy, in order to save a few miles of posts and wire, a telegraph-line 3 chains wide was cut through the very heart of the bush, and at the same time a settlement was laid out on the margin at a place where a heavy kahikatea swamp would for many years have prevented the encroachment of accidental fires. What any bushman would have foreseen was not long in happening. The fires on the telegraph-line were soon joined by those which spread from the settlement. The bush was first gutted and then swept; and at the present time the greater portion of this magnificent forest is destroyed. The same thing is going on on a large scale around the village settlements in the north, in every mining and timber district, and to a greater or lesser degree wherever a new encroachment is made.
