DISCUSSION 



Mr. C. W. Spofford (Office of Naval Research) : Were their 

 measurements in the direct path kind of region? 



Dr. F. M. Labianca (Bell Telephone Laboratories, Inc.): Yes. 

 One single bounce. 



Dr. W. H. Munk (Institute of Geophysics and Planetary Physics, 

 University of California at San Diego) : Your stochastic model is still 

 one-directional?
