REMARKS FROM VARIOUS AUTHORITIES, Analysis by Dr Hector, New Zealand Geo, Survey Laboratory. " This is good Petroleum—its spooitin gravity is 'BO4, and it yields good com mercial kerosene.' 1 (Signed) J, Hector. From Gerhard Mueller, Esq., Commis sioner Crown Lands. " I have been surprised beyond mea sure to see tho exudations of Petroloum at so many places in your Valley, all of which point to a great reservoir of this Oil somewhere thereabouts." 6.0. McAuley, Esq., Rotorua, 19t!i November, 18P1. " I was shown over only a small por tion of the ground, and in all places found Oil flowing freely-even in the bottom of tho stream—the eartli is also full of Oil. I consider the prospect is an excellent one. Tho numerous and varied, coloured earths aro also very valuable." P. B. Scott, Esq., Auckland, November, 1891. " I have resided in the locality of the Waiotapu Petroleum Springs for tho lastfeur years, and haye had every opportunity of calmly considering the probability of a reservoir existing in that locality, Throughout all this company's ground, oil is to be got on the.surfaco, a few feot below it; and also in the bed ot tho creek.' Hundreds of gallons must have been finding their way down this stream weekly. 1 consider the very fact of the ground being so'inuch disturbed by yojeanic acencies,. is very favourable to the supposition of subterranean cay« orns existing capable of containing large reservoirs of oil, which are often deficient in regular sandstone formation, Apart from tho petroleum, the value of this property is greatly enhanced by the ititoresting variety of hematites, acids and clays, which are found to putmoate tho whole formation. A com pound which might be termed paraffin butter is also found in quantities. This is a curious substance, and is very useful and effective as an anti-friction grease. Tho petroleum in its crude state makes an excellent salvo, and is largely used by tho natives tor hone sores, scalds, and wounds. NEWSPAPER EXTRACTS. Hot Lakes Chronicle, Jttotorua, 23111 Oct., 188;.
