the sea. These terraces are distinctly marked on the 

 north western side o£ the island, and traces of them 

 exist on the south eastern side. 



The two Islands are divided by shallow water. 

 The deepest part of this is the boat channel, which 

 ranges in depth from three fourths of a fathom to two 

 and a half fathoms. 



The greatest length of Flat Island is about 2,200 

 ■yards in a north easterly direction} from the rock on 

 which the lighthouse is built. 



The geatest width, also in a northerly direction, 

 from the Lime Kiln towards the Pigeon House Rcok, 

 is about 2,000 yards. It is also about the same width 

 from the landing jetty to the extreme point of the 

 rocks at Palissade Bay. 



At the southern extremity the Island rises in 

 precipitous rocky cliffs from the sea, to an elevation 

 of 350 feet at the lighthouse. The height of the 

 eastern part of the cliff is about 200 feet above the 

 sea. From this part of the island, spring two rocky 

 peaks, " Deux Mamelles," when rise to a height of 

 about 80 feet further. 



Half way between the lighthouse and the most 

 northern of these peeks, there is a steep cliff or dike 

 of volcanic rock and boulders. — The figure which this 

 dike partly surrounds, is like the end of an oval. — The 

 diameter of the space which the dike encloses on 

 three sides, is about 650 feet. — The section is open at 

 the southern side or end of the figure, and the dike or 

 wall curves round the circular end from the east, by 

 by north to west. — The length of the circumfer- 

 ence of the dike, as it exists, is about 1400 feet. — The 

 dike, from its form and character, looks, as if it was 

 the lip or rim of an extinct crater, three parts of 

 which cannot now be pointed out.— The inside of the
