'this that they grew where found, for the pieces of carbonized wood found 
in the same deposits were evidently drifted in, as this drift wood is found 
at various depths all over the south side of the island. 
This little isle by the sea still remains a geological puzzle. Stratified 
beds are found 260 feet above the level of the ocean as well as 500 feet be¬ 
low it. At Calvary Cemetery the rock was struck at a depth of 182 feet in 
the glaciated part of the island. In the unglaciated part, as at Woodhaven 
not more than three miles south of the former place, the rock is eroded to 
the extent of over five hundred feet. 
The following gives the results of the boring at Woodhaven:
