20, 2 Schenck: Physiography and Geology of Samar 235 
The final stage of the trip was from Basey to Calbiga, thence 
to Wright, and finally back to Catbalogan. 
ACKNOWLEDGMENTS 
I am particularly indebted to Mr. Moody for assistance 
rendered by him in the field, for his aid in the interpretation ot 
the data obtained, for his criticism of the manuscript, and for 
other important details: 
Dr. Warren D. Smith assisted me in the determination of the 
rocks and verified the classification that appears herein. He 
made many valuable suggestions, and I am deeply indebted to 
him for this aid. 
Dr. Roy E. Dickerson, of the Richmond Petroleum Company, 
has carefully criticised the paper, made fossil determinations, 
and otherwise assisted me in the preparation of the paper. I 
desire to express my sincere gratitude for this. 
Fr, M. Saderra Masé6, S. J., of the Weather Bureau in Manila, 
outlined some of the climatic conditions to me and supplied me 
with the note on recent earthquakes which forms a portion of 
this account. 
Prof. Frank G. Haughwout encouraged me by his never-failing 
interest in my work. 
The list of acknowledgments would be incomplete if I made 
no mention of the various Americans on Samar Island, par- 
ticularly Messrs. Frush, Shawger, and Ryans, who rendered 
valuable assistance to the party during its reconnaissance. 
Their codperation and interest made the work easier and more 
agreeable than it otherwise might have been. 
PHYSIOGRAPHY 
The name Samar perhaps is derived from the Visayan word 
samad, meaning “wounded,” or “cut up.” Although it cannot be 
said that the original namers of the island had physiographic 
peculiarities in mind, nevertheless, this definition well describes 
the island’s topography. Physiography has been, and still is, 
an important factor in the development of the province, and 
it is partly for this reason that more than passing attention is 
given the subject. 
RELIEF AND DRAINAGE 
As one approaches Samar from the west, he notices that the 
skyline of the island is more or less regular, though slightly 
Serrate, suggesting peneplanation or perhaps widespread ter- 
racing. Numerous small islands lie off the coast. A closer view
