Copper ore in several places amongst the mountains. Lead in a mine near Newtonards; rich specimens of ore amongst the rocks at Killough; near Dundrum; and Portaferry. Freestone quarries at Scraba and Kilwarlin; and slates at Bangor and other places. The mineralogist and geologist will find much amusement in the limestone quarries near Moira, containing specimens of marine exuviæ. Granite amongst the Mourne Mountains. Iron has not been found in ore, but the numerous chalybeates attest its presence.

DUBLIN. This county offers to the tourist a complete epitome of the whole Island. In the northern district are many bogs, yet in various points the most beautiful scenery opens to the view, presenting numerous villages with highly ornamented mansions and villas scattered around; except in some few spots, trees indeed are wanting; and extensive salt marshes spread towards the coast. S. of the Liffey there is very little tillage, but to the picturesque eye this is amply compensated by the wild uncultivated heaths, rocky mountains, winding glens, and sombre landscapes that extend on every side. The ancient inhabitants were the _Voluntii_ and _Eblani_; after them came the _Danes_ and _Ostmen_; in later times the county was always within the English pale. The Irish sea bounds it on the E., on the S. Wicklow, W. Kildare, and N. Eastmeath.
