find a difference in the course of the Waimata, and a slight difference in the Akitio river. I account for these discrepancies in this manner; our plan is a sketch map, showing the Topographical features of the country; the Waimata runs for its whole course through bush, now it is very difficult, almost impossible, to sketch in the true course of a stream that winds about in the forest, I would therefore give the small plan the preference, as showing the proper course of the Waimata; but as regards the fixed points such as Taumata-o-te-Atua, Whakaroro, and Rakaupuhipuhi, these points are determined from the Triangulation, and are certainly correct. The total area of the Akitio Run is a fair estimate, as the differences in the Rivers, will conpensate each other. The house built by Mr. Esdale, is in the Province of Wellington, but I think that part of the Block shown on the small tracing, Esdale 300 plus 15 Acres, is in Hawkes Bay. Since I was carrying forward the Triangulation from Hawke's Bay to Castlepoint, one of the Wellington Provincial Government Surveyors, Mr. Wilson, has been laying off lands in the neighbourhood of Akitio, so that a plan giving fuller particulars of the sold and unsold lands, could be obtained
