(10) Sulphur.

Sulphur is found universally as a constituent of the metallic sulphides, and also in the pure state in large quantities on White Island, off the coast of Auckland. At this place it is deposited from hot springe, as on other islands in the Bay of Plenty, where it is found in smaller quantities. Among the Rotomahana and Taupo fumaroles some sulphur is found, as at several other similar localities. Work has been carried on at White Island, whenever the volcanic agencies have been sufficiently subdued to render it safe.
