The most important springs are situated at Sulphur Point--a small peninsula at the southern end of Lake Rotorua. One of the most noted is Whangapipiro, a large circular pool of hot saline water, with silicates, and with an alkaline reaction. The water, which is only a few degrees below boiling-point, is perfectly blue, and as clear as crystal, and when you look down into its deep and apparently fathomless basin, the white, alabaster-like deposits of silica hanging around its sides make it appear like a picturesque grotto formed of coral rock. Near to this bath is Te Kauhanga, or the "Pain-killer," the water of which is saline, with excess of acid and acid reaction. It is very efficacious in cases of acute rheumatism, and many marvellous cures are said to have been effected by it. Not far distant is Te Kauwhanga, a large, muddy basin, with a constant discharge of gas, which rises in the form of large bubbles upon the slimy-looking surface. The waters of this bath are slightly saline, with excess of acid and acid reaction, while the gas which is constantly evolved produces upon many, when inhaled, similar effects to those of laughing-gas. Nearer to the lake is Te Pupunitanga formed by a warm spring of transparent water, the properties of which are aluminous, and strongly acid, with acid reaction. The water of this spring is very beneficial in cases of acute rheumatism and cutaneous disorders, and when used in its natural state--that is to say, without the admixture of fresh water--it produces a tingling sensation, and causes the skin to assume for a short time the redness of a boiled lobster. The "Coffee-pot" is a hole about twelve feet in diameter, full of hot, bubbling mud of the colour of coffee, and which rolls and splutters about in a constant state of ebullition. The "Sulphur Cups," not far distant, are formed by small sulphurous springs of various degrees of temperature, which flow out of circular, cup-shaped basins, about four feet in diameter, around which the bright yellow mineral is deposited in the form of glittering crystals, while the "Cream Cups"--delicate and beautiful in formation--are fashioned out of cup-shaped craters, from the centre of each of which shoots forth a jet of sulphurous gas and steam.
