his assistance in the field. My appreciation goes to Dr. Donald Baird, 
Department of Geological and Geophysical Sciences, Princeton Univer- 
sity, for his kindness in reading the original manuscript and offering 
suggestions for the improvement of the paper. The excellent photography 
of the figures is the work of Mr. Richard E. Grant of Dallas, Texas. Ap- 
preciation is extended to Mr. Richard Hamilton, Rockaway, New York, 
for his kind assistance on the art preparation for the figures and tables. 
This work was supported in part by a grant from the Griffis Fund of the 
American Littoral Society: GF-ALS-1812. Additional assistance came 
from the Scott Fund of Princeton University.
