A critical examination of observations and measurements of waves and the discovery of the mode of their 
production. The facts here set down in a very interesting manner are the results of fifteen years’ study of 
wave action in lakes and rivers as well as upon the ocean at different latitudes. 
A few of the topics ably presented are :— 
SIZE and SPEED of DEEP SEA WAVES; the numerical relation between length of fetch of wind and 
height of storm waves; the wave length of the swell which reaches shores after storms: the give and 
take between air and water in the development of waves; the effect of squalls and gusts upon waves. 
On the action of sea waves to transportshingle, sandand mud. The building up of beaches—the undertow. 
Stationary and progressive waves in rivers, flood waves, tidal bores, cross-stream progressive waves, sounds 
of running water, the gushing 
motion of cataracts, whirls and 
eddies, conical structures pro- 
duced by the breaking up of a ORDER BLANK
