§ Introductory. 
Diamond Island is a small lozenge-shaped islet off the Arracan 
coast. It is situated at the mouth of the Bassein River, in Long. 94° 
18' E. and Lat. 15° 51' hT., about 5 miles from Pagoda Point, 8 from 
Cape Negrais, and 9 or 10 from the lighthouse on Alguada reef. Its 
length is somewhat under a mile and a half, and it is about three quar¬ 
ters of a mile wide. The H. E. and S. W. corners which terminate its 
longer axis rise rather abruptly from the sea. Except, however, at the 
extreme eastern end its shore all round is rather bluff and rises rapidly 
to what is rather a central small plateau than a ridge, the general level 
of this central portion being about sixty feet above the sea. There are 
three small breaks, however’, in the sea-face; a little water-channel, dry 
in November, opens to the north; another, with a very little water in 
November, opens to the south; a third, somewhat larger and quite near 
to the last, has at one time found its way to the sea through the small 
patch of flat land on the east, but a bund having been thrown across its 
course, about 100 yards from the sea, its channel has been converted into 
a tank about 150 yards long and 40 wide.
