"Guernsey is 6o miles s. w. of Weymouth, about 26 W. of Normandy, 21 from Jersey, 5 from Alderney, and six from Sarke. It is about 12 miles long, nine broad, and 30 in circumference, containing 50 square rniles or 32,000 square acres. It has 10 parishes. The air is healthy, and its soil, like Crete and Ireland, is said to admit no noxious animal. It abounds with fish, particularly a fine sort of carp; and its rock produces a kind of emeral, very hard. The island is plentifully supplied with corn and cattle. Nature has defended it with a ledge of rocks, and art with an old castle, and a pier constructed of vast stones, thrown together with great art in the days of Edw. II. Here is a great scarcity of wood for fueling, which is supplied by the sea vraic."
