“ Westmeath is essentially a county of the great Carboniferous Limestone plain, with numerous lakes occupying the hollows. Two or three little inliers of Old Red Sandstone, as at Killucan and Moate, form distinctive hills, about 500 ft. in height. At Sron Hill near Killucan, a core of Silurian strata appears within the sandstone dome. A considerable system of eskers, notably north of Tullamore, diversifies the surface of the limestone plain. The soil is generally a rich loam of great depth resting on limestone, and is well adapted both for tillage and pasturage. ”
