blocks of seolian rock thrown up above high-water mark, and above this 

 belt it is covered with low shrubs. When we finally come to Memory 

 Rock, we find nothing but a few pinnacles of seolian rocks, pitted and 

 honeycombed, and worn into fantastic shapes, the only land still visible 

 of the northern part of the older Bahama Abaco Land. 



The northwestern extremity of the bank is fringed by patches of coral 

 reefs and sand bars. The reef which extends nearly unbroken from 

 Southwest Point on Great Abaco along the western face of the Little 

 Bahama Bank beyond Memory Rock runs to within about fifteen miles 

 from Matanilla Shoal, the northernmost coral patch on the bank.

The character of the bottom on the bank from Memory Rock for about 

 thirty miles eastward is that of grayish coral sand, rather finer than the 

 bottom samples near the edge of the bank, which are clear coral sand 

 and broken shells. At each haul of the dredge masses of Thalassia 

 were brought up. 



The Barracouta Rocks, five to six isolated little rocky patches, twelve 

 to fourteen feet high, are pitted and honeycombed, and water-worn 

 at the base. The seolian lamination in some places is most distinct, 

 dipping at times thirty-five to forty degrees. The cavities of these 

 rocks were in part filled by very peculiar rounded lumps of a cellular 

 mass of red earth, sometimes also arranged in ridges on the dividing 

 edges of adjoining depressions. 



Little Sale Cay rises about twenty feet above high-water mark, and is 

 devoid of vegetation. It is, like the Barracouta Rocks, the remnant 

 of a larger island, which must have covered the greater part of the 

 bank to the north of the eastern end of Bahama Island. Little Sale

Cay, the Barracouta Rocks, and the Centre of the World, standing as 

 they do as the outposts most exposed to the agency of the waves, are 

 cays and patches of rocks the outlines of which have been far more 

 affected by the action of the sea than the more eastern range of inner 

 cays, which protect the eastern extremity of Little Abaco.
