 and during the summer the bathers visited it in crowds. Now it is a 

 strand of mud almost entirely abandoned. The Island of Noidstrand 

 has diminished by eleven-twelfths since the commencement of the 

 seventeenth century, and of the 24 islets which surrounded it 300 

 years ago, there only remain 11 : the lead, when thrown out at the 

 spot which was formerly in the centre of the island, indicates a depth

 Schleswig, have been also much worn away, and it is known that 

 in 1825 the sea opened a way quite across the peninsula of Jutland 

 by hollowing out the Strait of Lymfjord.*
