them dead, except ihose which were a foot above the 

 high water-mark of that day, which was February 2, 

 1788. The shells were evidently altered a little in 

 proportion to their height above the water, but by no 

 means so much as to induce one to believe that the 

 rock had been many years out of it. All the adja- 

 cent islands and the coast shewed similar appearances, 

 and therefore it was evidently no partial elevation by 

 subterranean fires, or any thing of that sort ; this is 

 also apparent from the island of Cheduha itself, in 

 which there is a regular succession of sea-beaches and 

 shells more and more decayed to a great height. 

 By a kind of vague estimation from the trees and the 

 coasts and shells, &c. (on which however there is not 

 the least dependence) I supposed that the seami^hc 

 be subsiding at the rate of about three inches in a 

 year.
