teen elephants' tusks, a large quantity of cedar, four cannons, 

 the remains of a number of swords, muskets, and chains, a 

 number of small shells, some coral, a piece of metal, nearly 

 in the shape of a horse-shoe, which, at the time, we supposed

 on the coast of Guinea, and the shells have been classified as of

" Mr. Burdon had satisfied himself that the first which he 

 examined was natural, when his attention was attracted by a 

 large stone in the face of a ditch, which had been made re- 

 cently, traversing the hillock; he found it to be a flag, and, 

 when pulled down, it proved the head-stone of a rude stone
