From the westward of Cape Maysi to Caleta Point there are four very- 

 distinct terraces, and signs of a fifth, the summit of the hill forming 

 Caleta Point being probably nearly twelve hundred feet in height. The 

 accompanying sketch will give better than any description of mine an 

 idea of the appearance of the shore as seen from the yacht's deck. As 



TERRACES AT CALETA POINT. 



we go westward these terraces become more and more indistinct. 

 They are no longer continuous, as we saw them for a long stretch 

 to the eastward of Caleta Point. There has been great erosive action, 

 and many valleys have been cut from the shore through the lime- 

 stone hills back to the older formations upon which the shore hills rest. 

 During the erosion, the hills parallel to the coast line have been cut into 

 disconnected patches, and often reduced to a height less than that of the 

 second or third terrace on the shore line near Caleta Point. In the 

 process the lines of the terraces have also frequently been obliterated, so 

 that it is impossible to detect their continuity. Here and there iso- 

 lated remnants, generally of the third terrace judging from their com- 

 parative altitude, can be traced at intervals all along the shore line to 

 Santiago de Cuba. The first terrace formed by the line of the elevated 

 shore reef is most persistent ; it can often be traced for miles where the
