tain the most feasible methods of working. I then made a reconnois- 
sance east to Villa Clara, from which point a reconnoissance was made 
north and south across the island. This trip was made primarily to 
obtain some knowledge of the interior of Cuba. I was accompanied by 
some American engineers who were familiar with the island, and who 
were of great assistance to me in my subsequent operations. Returning 
from Villa Clara to Havana, I stopped at several points, including 
Matanzas and neighboring places. There were many opportunities to 
study the basal contacts and structure of the limestones in relation 
to the older nucleal area of Cuba upon which they were deposited. At 
Matanzas I made a thorough study of the cut of the Yumuri River 
of Matanzas, and of the limestone formations composing the Pan de 
Matanzas and the country to the interior, as set forth in the following 
pages. Returning to Havana from Matanzas, I spent a few days studying 
the geology of the site of that city and its environs, and in making a 
north and south section across the island from Havana to Batabanos. 
On February 28, a coasting steamer was taken from Havana for 
Baracoa, which stopped for four or five hours at various points on the 
way. I arrived at Baracoa on the 4th of March. With Baracoa as a 
base, I made a study of the country west of Yunque mountain and east 
to Cape Maysi, taking a trip up the Yumuri River of the east. 
I sailed from Baracoa on the 13th of March, arriving at Philadelphia 
on the 18th. 
I wish to acknowledge my obligations to Mr. E. Sherman Gould, of 
New York, Consulting Engineeer of the Havana Water Works ; Rev. 
Lorenzo J. Arrubla, of Real Colegio de Belen, Havana; Sejior S. Fortun, 
Chief Engineer of the United Railways of Havana; Hon. A. B. Dickey, 
Consular Agent of Baracoa, and many others throughout the island, for 
valuable data furnished ; also to Prof. W. H. Dall of Washington, for 
his valuable assistance in paleontologic determinations of the age of the 
rocks discussed herein. 
Looking back at my expedition, I now see many points which I would 
like to examine again, but I hope that, upon the whole, you will not be 
dissatisfied with the results. 
Very truly yours,
