AND OTHER WATER WAVES 127 



statute miles per hour, as in the above case, the 

 length of fetch, or stretch of water, at any one 

 time subject to this wind would be 73 statute miles, 

 in which there would be a train of only 200 of 

 the 1,918 foot -waves. 



It may in this connection be noted that in a 

 gust lasting i minute, and in which the locus pf 

 application is advancing at the same rate (36.5 

 statute miles per hour), the length of fetch would 

 be only about half a mile i.e., less than two pf 

 the above wave-lengths. The absence of breakers 

 with speeds nearly as great as the maximum wind 

 speed of gusts may, therefore, be properly attri- 

 buted as much to their insufficient length of fetch 

 as to insufficient time of action. 



The charts for February 2 and 3, 1899, in the 

 publication of the Meteorological Council to which 

 I have so often referred, afford an excellent 

 example of a long -continued hurricane -force of 

 wind which was stationary in position for 24 hours. 

 After examining these two maps, I made the 

 following note, viz : 



" Maps for Eebruary 2nd and 3rd show 

 hurricane -force (centre about N. 45, W. 45), 

 with no appreciable length of fetch indicated, 

 occupying almost the same considerable frontage 

 for 24 hours. In this area must have been a
