In the Slieve Bloom Mountains are quarries of a soft white sandstone, which hardens when exposed to the air, and is susceptible of a high polish; it is in great demand throughout the country for chimney-pieces and hearth-stones; a coarser kind is used for flagging. Another peculiarity of these mountains is the fertility of their northern side, which is interspersed with neat farm-houses and cultivated enclosures to its summit, while its southern side is mostly a heathy waste. Iron ore was formerly raised, but is not now. There is a large tract of bog in this district, affording an abundant supply of fuel. Tillage is more attended to than grazing: there are but few flocks of sheep. The chief crops are potatoes, wheat, barley and oats.
