sea have occurred on the other West Indian islands and on the 

 continent; and, from the amount of work accomplished, the 

 Pleistocene period seems to have been one of long duration. 



Outside of Jamaica the geological features of that beautiful 

 island would not be of special interest, except that here we find 

 additional evidence, both upon land and in the adjacent sea, 

 supporting the theory of the high continental conditions of the 

 West Indian region in the early Pleistocene period, when the 

 land stood more than two miles above the present altitude, 

 uniting North and South America, as is set forth in the " Recon- 

 struction of the Antillean Continent,"
