Notice of a Vein of Bituminous Coal., recently explored in the vicinity

The surface of the country, from Guanabacoa eastward to the mining 

 property above mentioned, is undulating, and partakes of those charac- 

 ters which are so marked elsewhere in this island, where the serpen- 

 tines and the euphotides are the predominant rocks. 



In leaving Regla, on the south side of the bay of Havana, the eupho- 

 tides, which Monsieur de Humboldt has described here, and which we 

 found also to exist, with similar characters, in the district of Halguin, 

 towards the northeastern end of the island, are here evidently the most 

 predominant rocks ; occupying a breadth of about two leagues, within 

 which area the city of Guanabacoa and the adjacent Petroleum springs 

 are situated. 



Having next passed a belt of about a mile in breadth of white rock,

 rock, which we had not sufficient leisure to examine closely, we arrived
