Ireland, Historic and Picturesque

Excerpt

Think of the sea gradually rising around her coasts, until the waters, deepened everywhere by a hundred fathoms, close in upon the land. Of all Ireland there will now remain visible above the waves only two great armies of islands, facing each other obliquely across a channel of open sea. These two armies of islands will lie in ordered ranks, their lines stretching from northeast to southwest; they will be equal in size, each two hundred miles along the front, and seventy miles from front to rear. And the open sea between, which divides the two armies, will measure seventy miles across.
