At Waimea Plains, Mataura, Castle Rock, Dipton, Waiau, and Limestone Plains, of excellent quality, is known to exist. Several circumstances have combined to delay working these deposits, except for buildings in the several localities. But business enterprise will in due course ensure these quarries being efficiently and profitably worked. Mr Blair, Engineer-in-Chief of the South Island, in a report, says that the granular limestone found in Southland exists in a broad zone extending across the country from the Mataura to the Waiau. It belongs to the same class as the famous Oamaru stone, but is much harder and heavier, and will absorb only one-third the quantity of water that the same quantity of Oamaru stone will absorb. He says, also, that this Southland stone, unprotected, is far more impervious than the Oamaru stone when covered with oil, and he further points out that the imperviousness of the Southland stone has boon well proved at the residence of Mr G. M. Bell, Waimea Plains. A nine-inch wall on the south or shady side of the house was papered on the bare stone, and no damp was ever observable.
