I have an idea our friend Ragobah might be able to throw some light upon this subject, therefore I am starting on my way to visit him this afternoon, and shall write you en route whenever occasion offers.  My kindest regards to Miss Darrow. 
                                           Yours sincerely,
          
                                        George Maitland.

P. S. I shall have leisure now on shipboard to set tie that question of atomic pitches, which is still a thorn in my intellectual flesh.

I handed this letter to Gwen, and, after she had read it through very carefully, she questioned me about this new theory of Maitland’s.  I went through the form of telling her, after the usual practice of amiable men discoursing to women, feeling sure she would be no wiser when I had finished, and was dumfounded when she replied:  “It looks very reasonable.  Professor Bjerknes, if I remember the name, has produced all the phenomena of magnetic attraction, repulsion, and polarisation, by air vibrations corresponding, I suppose, to certain fixed musical notes.  Why might not something similar to this be true of atomic, as well as of larger, bodies?”

If the roof of my house had fallen in, I should not have been more surprised than at this quiet remark.  How many times had I said:  “You can always count on a young woman, however much she flutter over the surface of things, being ignorant of all the great underlying verities of existence”?  I promptly decided, on all future occasions, to add to that—­“When not brought up by her father.”  I was convinced that of the attainments of a girl educated by her father absolutely nothing could be definitely predicted.

We had a short note from Maitland written at Trieste.  He excused its brevity by saying he had been obliged to travel night and day in order to reach this port in time to catch the Austrian Lloyd steamer Helois, bound for Aden, Bombay, Ceylon, Singapore, and Hong Kong.  From Aden I received the following: 

My dear doctor: 

We have just been through the Red Sea, and I know now the real origin of the Calvinistic hell.  Imagine it!  A cloudless sky; the sun beating down with an intolerable fierceness; not a breath stirring, and the thermometer registering 120 degrees F. in the shade!  It seemed as though reason must desert us.  The constant motion of the punkas in the saloons, and an unlimited supply of ice-water was all that saved us.  Sleep was hardly to be thought of, for at no time during the night did the mercury drop below 100 deg.  F. Apart from the oppressive heat referred to, the entire voyage has been exceedingly pleasant.  I have not solved the atomic-pitch problems, as attendance at meals has left me little time for anything else.  They seem to eat all the time on these boats.  At 8 A. M. coffee and bread; at ten a hearty breakfast of meat, eggs, curry and rice, vegetables and fruit; at 1 P. M. a luncheon,
