usefulness. Certainly their value must rest very largely on the use of empirical 

 substitutes for hydrodynamic theory. It was for considerations such as this that 

 my paper was totally lacking in discussion of short-crested- seas problems. How 

 can we hope to solve such problems when we have not been able to solve the long- 

 crested-seas problems? 



Nevertheless, it is pleasant to anticipate the prospect that, if and when the 

 hydrodynamic ists make breakthroughs in the future, the statistical apparatus 

 will all be waiting for them — ready to cover not only linear problems of short- 

 crested seas but nonlinear ones as well.
