points can be represented by a curve, but if it is attempted m it 

 might be expedient to depart from the curve given by Sverdrup 

 and Munk somewhat in the manner indicated by the dashed line in 

 Figure 3."' He states further that a very considerable increase in 

 steepness is assumed with the youngest waves immediately after their 

 formation, then their steepness very quickly approaches the relation 

 as shown by the dashed line in Figure 3, and that the relationship 

 between steepness and wave age is not yet completely explained. 



The influence of the fetch on wave height and wave age as de- 

 veloped by Sverdrup and Mink is compared with that indicated by the 

 Neuwerk wave measurements in Figure U, and generally speaking, agree- 

 ment may be regarded as satisfactory,. Differences that are apparent 

 are believed by the author to be not wholly the result of inaccurracies 

 in measurement, but probably are due more to the minor descrepancies 

 previously shown between theory and measured values. However, the 

 author regards the results of the Neuwerk wave and wind measurements 

 as a verification of the Sverdrup-Munk theory on the growth of sea 

 waves due to the influence of the wind.
