20-foot constructional bench. All sediments ex- 
cept the beachrock are unconsolidated and ap- 
pear to be of Recent age. 
ACKNOWLEDGMENTS 
All of the costs for field work, thin sections, 
air photos, maps, and so forth, were defrayed 
by funds from National Science Foundation 
Grant No. GP-2196. Air photos and maps were 
obtained from the Topographic Division of the 
U.S. Geological Survey. G. A. Macdonald aided 
with many helpful comments both in the field 
and in the laboratory. Both Macdonald and R. 
Moberly, Jr., of the Hawaii Institute of Geo- 
physics critically reviewed the manuscript. 
The field work in Samoa was undertaken with 
the permission of High Chief Lefiti, District 
Governor of Manu’a. The Samoan people were 
extremely cooperative and their hospitality was 
overwhelming. Especially appreciated was the 
assistance of High Chief To’atolu Nua of Ta’u 
Village; Reverend Soloi of Fitiiuta Village; 
Chief Milo and Ai Fa’i of Olosega Village; and 
Sione Malauulu, High Talking Chief Velega, 
and High Chief Misa of Ofu Village. Without 
the help of the Samoan people the field work 
would have been much more difficult, if not 
impossible.
