The report of Messrs Gledhill & Hamerton sets all doubt at rest as to the unlimited abundance of iron-sand at Taranaki. On arriving at the east bank of the Henni river, they proceeded to dig at several places, with the following results: In the space situated between the sandhills and high-water mark they found solid iron-sand to the depth of 4 feet, and no apparent change at that depth. Previous experiments afford grounds for the belief that the deposit of iron-sand varies from 15 to 30 feet in depth.
