an inland route; and the details are given with considerable precision. The report of Messrs. Heaphy and Spooner carry us from the western extremity of Mr. Cotterell's route southward into the interior. The report of Mr. Tuckett connects the starting point of the two preceding routes with the upper waters of the Pelorus, leaving a very inconsiderable tract to be explored in order to connect them with the Wairau valley explored by Mr. Cotterell.
A pass by which there is easy access from the valley of the Pelorus to that of the Wairau has since been discovered.
The route described in the fourth paper crosses an elevated range of rather peculiar geological construction, a continuation of the high land of which Mount Arthur (above the line of perpetual snow) is a summit, from the Motuaka valley to a river which flows N. and S. into the Massacre Bay of Tasman—now more commonly called Coal Bay, from the large quantities of that mineral found in it. The impression produced by these papers is, that the district of the Middle Island of the New Zealand group, N. of a line drawn from Cape Campbell to Cape Ferdinand, is the N.W. declivity of a huge mountain mass, and is surrounded by the three principal valleys:—that of the Wairau, flowing into Cloudy Bay; that which contains the parallel sub-valleys of the Waimea and Motuaka, flowing into Tasman's Gulf; and the valley of a nameless stream, the embouchure of which was seen by Dumont D'Urville, immediately N. of Cape Ferdinand, together with a number of lesser valleys.
1.—Mr. Cotterell's Route from the Waimea to the Wairau Valley.
"November 17th, 1842. The distance performed this day was 6 miles in all: the first 4 miles in the direction of S.S.W.; the remaining 2 miles in the direction of S.W. The course of the first four miles proceeded along a branch valley of the Waiiti, which had an average width of 10 chains, expanding at its eastern extremity to a small plain of 300 acres. From this valley the route ascended to a table-land, and descended thence into a second branch valley of the Waiiti, 40 chains in breadth and bearing fine grass.
"18th. The distance performed this day was 10 miles: 3 miles in a W.S.W. direction; 2 miles S. and W.S.W.; and 5 miles S.S.E. The first 3 miles brought the travellers over a hill covered with fern and manuka into the main valley of the Waiiti. The valley was wooded and 30 chains in width. Where the river was struck its course was from S.E,; but it appeared to issue from a narrow gorge in the mountain-range to the E.N.E. Two miles from where the Waiiti was crossed, passing along a high range of hills, a river was seen to the W., judged to be the Motuaka. Following an intermediate valley for 5 miles S.S.E., brought the party into the Motuaka valley. The hills on either side were very high, and covered with flax and fern; the width of the valley 80 chains; the soil was poor, bearing grass.
