are the salt ponds of the island. There is an entire absence of ele- 

 vated terraces, unless some apparent shoulders on outlying islets, not 

 actually visited by me, should be slightly elevated sea-out benches. 

 Wave-cut cliffs margin the rocky shores, and alluvial flats occur 

 around the heads of the bays. 



The shore line of St. Martin is indented. Each reentrant into the 

 land is usually divided by a transverse beach into an inner lagoon or

 heads of the reentrants and project inland between the hills. The 

 spurs along the shore are truncated by wave-cut cliffs (see pi. 69, 

 fig. A) and exhibit no definite terracing. Older beach rock was seen 

 at the northeast end of Blanche Point, perhaps indicating slight 

 differential uplift for that locality. 



The shore line of Anguilla (see pi. 69, figs. B, D), although not 

 so conspicuously indented as that of St. Bartholomew and St. Martin,
