72 HAS SCIENCE DISCOVERED GOD? 



coming first in this book are difficult reading. Even 

 if they are true, they are not particularly interesting, 

 and I am one who finds difficulty in believing that all 

 of the pronouncements in this early portion of the 

 book are true. By and large, however, it is an epoch- 

 making book. One should read it in the manner 

 popularly supposed to be distinctly and peculiarly 

 feminine, by reading the last few chapters first. May 

 I quote from the beginning of the last chapter? 



One day I happened to be occupied with the subject of "Gen- 

 eration of Waves by Wind." I took down the standard treatise 

 on hydrodynamics, and under that heading I read, 



"The equations (12) and (13) of the preceding article enable 

 us to examine a related question of some interest, viz. the main- 

 tenance of waves against viscosity, by suitable forces applied to 

 the surface." 



[Here there follow some complicated and intricate mathe- 

 matical equations.] 



And so on for two pages. At the end it is made clear that 

 a wind of less than half a mile an hour will leave the surface 

 unruffled. ... At two miles an hour the gravity waves appear. 

 As the author modestly concludes, "Our theoretical investiga- 

 tions give considerable insight into the incipient stages of wave- 

 formation." 



On another occasion the same subject of "Generation of 

 Waves by Wind" was in my mind ; but this time another book 

 was more appropriate, and I read, — 



"There are waters blown by changing winds to laughter 

 And lit by the rich skies, all day. And after. 



Frost, with a gesture, stays the waves that dance 

 And wandering loveliness. He leaves a white 



Unbroken glory, a gathered radiance, 

 A width, a shining peace, under the night." 



The magic words bring back the scene. Again we feel Na- 

 ture drawing close to us, uniting with us, till we are filled with
