eastern horizon lighted by little flashes, the source of which 

 cannot be seen. You call it " heat lightning," but it is really 

 the last signal that we can see of the vanishing thunder storm, 

 so far away that the sound of the crashing thunder cannot 

 be heard. 



You watch the mysterious flashes : they grow^ dimmer and 

 dimmer and finally you see them no more. Our summer shower 

 is gone. It has done what thousands of others have done before, 

 and what thousands of others will do in the future. It has 

 started, moved off, and finally disappeared from sight ; and as it 

 has gone it has told us a story. You can read a part of this 

 story if 3^ou will ; and in reading it will find much that interests.
