NORTH ROCKS, otherwise called St Patrick's Rocks, from a seat of stone amongst them called St Patrick's Chair, whence the rocks have taken this second name, are
situated in the harbour of Donaghadee, in the county of Down, and province of Ulster, in Ireland. From north to south they are about two thirds of a league, between which is clear good ground. But care must be taken to avoid the south rock, on which many ships have perished; for it is overflowed by every tide, and no crew can save their lives if the wind blows high. This rock stands fully a mile from the shore.
