the Miocene beds of wash, from which they were doubtless a concent rat 1011 product, and it is possible" that similar deposits may ye! be encountered iii other parts of the subdivision. Leads of payable gold occur In the sands along the sea coast, and beach combing is still carried" on with more or less success. (3.) Coal. Small seams of lignite occur within the subdivision in association with (he Oamaru beds near the sea coast. The enal is said to be fairly satisfactory for household purposes, though somewhat sulphurous. None has as yet been eiicmititered within the subdivision by the Geological Survey . (I. i l.i mi stum . The bed of limestone constituting one of the lower members of the Oamaru Series outcrops frequently along the edge of the mountains. Il appeals, as far as present observa fions are concerned, never to exceed 80ft. in thickness. In this thickness it shows every gradation from conglomerate with calcareous matrix to high-grade limestone. Beds of the latter may yet be found of sufficient extent to warrant the manufacture of lime and cement, or for use as a basic flux in metallurgical operations. (5.) Building-stone. -Much of the granite of the interior mountainous region is eminently suitable for use in building and for ornamental work, though its general inaccessibility would militate against its successful exploitation on a large scale.

Mn. James llknuy Adams. Assistant Geologist. Mr. .1. 11. Adams, who joined Mr. Colin Krascr's party as a tempera ry Held assistant on the Slh October, 1906, was permanently appointed to the staff as an Assistant Geologisl on the Ist April, 1007. He assisted Mr. Fraser both in held and office work until the oth January, 1008, when he lefl Wellington for Cisbmne to commence held operations in the Whatatutu Subdivision of the I'aukuinaia Division. Mr. Adams presents the following brief summary of the work accomplished : — Work in tin Whatatutu Subdivision. The area which is lo constitute the Whatalutu Subdivision of Raukuinaia. Hawke's Ray, emu prises the Mangatu and Waingaromia survey districts, and is a rectangle of 25 miles h\ 124 miles. thus having all area of .",124 square miles. The pmi ion of this subdivision to which work has been confined during the past live months represents about one-third of (he total area. The Waingaromia River, north-eastward from its confluence with the Waipaoa, together with all its main tributaries, excepting the headwater port ions of the Parariki and Makahakaha streams, has been geologically surveyed to and beyond the northern limits of the subdivision. The Waipaoa River has. together with its main tributaries, been surveyed geologically for a distance of about seven miles above its confluence with the Mangatu. Some work has also been carried out in the north eastern portion of the subdivision, and under your personal supervision a detailed survey was made of an area including Waitangi Hill, where good surface indications of petroleum occur. Physical Geography. The area included within the Whatatutu Subdivision consists, physiograpliically, of a series of rolling ridges of moderate height, separated by deeply cut river valleys. Its general slope is ill a sunt Ii easterly direction from the f'aukumara Range to the sea coast. The area has been dissected by; drainage channels converging from the east, the north, and the west to a point of junction about two miles below the median point of the southern boundary of the subdivision. The highest peaks included ill the area are situated in the western portion of the Mangatu Survey District. Of these, Maungaham ia (3,983 ft.), on the Raukumaia Range, is the most prominent. Other well-known peaks are Whelurau ,1,730 ft.), Pyramid A (2,200 ft.), Arakihi (2,302 ft.i. Ahititi (1,911 ft ), and Paraheka (1,867 ft.V Almost the whole of the area is included in the watershed of the Waipaoa or Big River, xvhich debouches into the western corner of Poverty Ray. The main Waipaoa River enters the subdivision close to the eastern boundary of the Mangatu Survey District, ami flows in a general southerly direction through the main central portion of the area. 111 the vicinity of Whalatutu the Waipaoa is joined by the Mangatu River, which drains the country to the west and north vest, and by two left-hand branches, the M a ngal aika pu a Stream and the Waingaromia River, which together drain the central and north-eastern portions of Ihe area. The Wheao. the Waikohu. and the Waihora. all tributaries of the Waipaoa, but junctionincr with il outside of the subdivision, have portions or the whole of their watersheds within the subdivision. A small portion of the area under description is drained by branches of the Pakaiae River, which flows south-east to the coast-line at the township of the same name. All these rivers and larger streams flow at grade. They are in places bordered by somewhat extensive high-level and low-level terraces, the most conspicuous of these being the flat-topped upland extending from Whatatutu for several miles along the right or xvestern bank of the Waipaoa River.
