Londonderry, Antrim, and Down; the latter of whichJt touches by a small point on the south-east side. It re-ceives six considerable rivers, four of smaller note, andseveral brooks; notwithstanding which, it has but oneoutlet for the discharge of this great flux of waters. Among!ts peculiarities, it has that of petrifying vegetable sub-stances.
Lough-erne is divided into two branches, the Upperand Lower, which are thus formed by the water being con-tracted into the compass of a considerable river for severalmiles, after which, having spread, it forms the lower lake.In both its branches, it takes its source through the whole,length of the county of Fermannagh, from the south-eastpoint to the north-west, nearly dividing it into two equalParts. It abounds with a great variety of fishes, among'Which are pike of a prodigious size.
