 ever discovered were some iron bars and a piece of chain. 



Another lighthouse was built a few years afterwards, but

 model has been followed ever since. The reader will see, by a

Having settled the form of the lighthouse, and made it like

 and, in fact, to give it roots of etone. For this purpose, he
