as the result of a comprehensive study of meteorological data of 

 long periods covering some great area like the United States. 

 While we cannot make such prediction today, we feel that we 

 are laying the foundation of a system that will adorn the civiliz- 

 ation of future generations. At the present time I know of no 

 scientific man who essays to make long range predictions and 

 in closing this paper I would especially caution the public against 

 the imposture of charlatans and astrologists who simply prey 

 upon the credulity of .the people. I believe it to be impossible 

 for any one to make a forecast based upon any principles of 

 physics or upon any empiric rule in meteorology for weeks and 

 months in advance.
