HOT SPRINGS AT HENDE'S FERRY, WANGANUI RIVER, SOUTH WESTLAND.

Presented to both Houses of the General Assembly by Command of His Excellency.

Mr. C. Malfeoy to the Hon. the Pbemieb. Sic,— Eotorua, 30th May, 1893. Be hot springs at Hende's Ferry, Wanganui Eiver, South Westland, I have the honour to report that, upon receipt of your telegram dated the 28th February last, being then at Boss, I at once made arrangements to visit the springs referred to. I started on the 3rd March. On my way down I inspected what I shall call " Spring No. 1," which is situated in a small creek emptying itself into Lake lanthe, on the eastern side of the South Boad. It flows out of a well-defined source close to the bridge, and about sft. from the edge of the creek. The quantity of water discharged is from 12 to 15 gallons per minute; temperature, 54° Fahr.; whilst the water of the creek was 56° Fahr. It smells strongly of sulphuretted hydrogen, deposits a white filament of what is usually called " baragene," and does not affect the ordinary blue litmus paper. The result of the analysis is that it contains only 6-21gr. of fixed matter per gallon, and therefore considered of no notable value for medicinal purposes; but it has not been quantitatively analysed. I was, however, informed by the roadmen employed in the vicinity that if taken in small quantities it acts as a purgative. Such being the case, and the fact of its being cold, therefore not liable to degenerate or undergo chemical changes by exposure, it might bo worth looking into more closely, as it may prove a valuable water for exportation. "Spring No. 2 " is situated on the north-west or left-hand bank of the Wanganui Biver, about a mile above Hende's Ferry, and is easily accessible from the main road. The water oozes out a foot or so above the level of the river from a perpendicular bank or terrace of comparatively recent river-drift gravel formation 15ft. to 20ft. high, and at a distance of about half a mile from the foot of a rather high range. The hot water can be traced for a distance of about 5 chains along the river-bank, increasing in temperature towards the centre, where, after doing some excavation, I obtained the sample of water sent for analysis. The quantity of water discharged is estimated at 50 to 60 gallons per minute. The temperature was from 50° Fahr. to 104° Fahr., whilst the riverwater was only 47° Fahr. Ordinary blue litmus paper is slightly affected by it. The sample of water analysed is, however, of necessity, diluted with a certain quantity of ordinary drainage-water. This must greatly interfere with the analysis, which in this case is 26-47gr. of fixed matter per gallon, and being quantitatively analysed places it under the category of chlorinated saline water (or chloruree socliqite of Dr. Duran-Fardel), and is, according to the same authority, suitable for internal and external use, and would prove valuable in scrofula, lymphatism, rheumatism, paralysis, surgical affections, hasmorrhoids, dermatose syphilis, dyspepsia, &c. " Spring No. 3."—This spring is situated in a low island, in the middle of a rather large creek (named Hot Spring Creek), on the south-eastern or right-hand side of the Wanganui Eiver, about six miles up the river from Hende's Ferry, and under present circumstances is quite inaccessible to any one having any kind of ailments, as the only road to it is along the river-bank, travelling on foot, jumping from boulder to boulder, besides having two rather large creeks to cross. The water oozes out in several places through the river drift of quite recent formation. The principal spring is in a hole under a large stone, where the temperature of the water was only 64° Fahr. when we arrived, but by turning the creek-water off, and cutting a drain so as to drain the hole, the temperature rose to 130° Fahr. in about two hours, and by thrusting the thermometer in the sand at the bottom it rose to 134° Fahr. This would lead one to believe that this spot is not very far from the actual spring. The quantity of water discharged is about 30 gallons per minute. Globules of gas (probably carbonicacid gas) were continually rising through the water," which emits a ■ strong smell of sulphuretted hydrogen and deposits white and green filaments of " baragene." It did not affect the ordinary blue litmus paper, but a shilling placed in the sand at the spring w 7 as thoroughly discoloured by the action of the sulphur. The analysis of this sample gives 9-62 grains of fixed matter per gallon. It also has not been quantitatively analysed, but, judging from the geological formation of the surrounding country, I am of opinion that if Nos. 2 and 3 springs were traced to their respective sources these waters would be found of the same chemical composition, and therefore identical in their use and applications, as both of them seem to rise at the junction of a huge moraine and lacustrine formation with the schist formation of the main range, but, as I said before, with regard to No. 2, it is difficult to say how much genuine hot mineral water there was in the sample analysed.
