When it is considered that in company only with my interpreter, and with but three horses--ultimately reduced to two--and with what scant provisions we could carry, I accomplished considerably over 600 miles of travel, discovered many new rivers and streams, penetrated almost inaccessible regions of mountainous forest, found extensive areas of open plains suitable for European settlement, traced the sources of three of the principal rivers of the colony, examined the unknown shores of its largest lake, ascended one of the highest mountains of the southern hemisphere, experienced degrees of temperature varying from 80° in the shade to 12° below freezing-point, and successfully traversed from South to North, through its entire length, a territory with an area of 10,000 square miles, and which had been from the early history of the colony rigorously closed to Europeans by the hostility of the native tribes, it may be readily seen that the explorations, by their varied nature, disclose many important facts hitherto unknown concerning a vast and beautiful portion of New Zealand; and while they cannot fail to prove of practical utility to the colony, they will, I venture to think, be a welcome addition to geographical science. The map appended to this work may be said to form the most complete chart of the interior of the North Island as yet published. Up to the present time the extensive territory embraced by the King Country has, owing to the obstruction of the natives, never been surveyed, and consequently many of its remarkable physical features have remained unknown, the existing maps of this part of the colony being mere outlines. As, therefore, considerably more than half of the country traversed was through a region which was, to all intents and purposes, a _terra incognita_ from the commencement of my journey, I adopted a system of barometrical measurements and topographical observations, and thus secured a supply of valuable material, which I mapped out from day to day, while the names of mountains, rivers, valleys, and lakes were obtained from the natives by the skilful assistance of my interpreter, who was at all times unceasing in his endeavours to carry out this part of the work with accuracy.
