Belt
Belt, Great and Little, two straits connecting the Baltic with the Cattegat. The Great Belt flows between the islands of Zealand and Funen and is about 70 miles long and 15 miles broad; the Little Belt separating Funen from the mainland of Schleswig is of similar length to the Great Belt, but only about half as wide. Both are perilous to navigators, who usually prefer to go by the Sound, which lies to the east.
