Mr. Clayton has long been active in meteorological work, his 

 specialty being the investigation of the fundamental cosmic relations 

 of the subject. He has occupied the posts of meteorologist of the 

 Blue Hill observatory and local forecaster of the U. S. Weather 

 Bureau. While in charge of forecasting in Argentina from 1913 

 to 1922 he studied methods of prognosticating the weather in that 

 country from solar data. His researches on the relation between 

 solar activity and the weather have been continued in cooperation 

 with the Smithsonian Institution, by which organization they 

 have been published. He has also written a book on the subject 

 entitled "World Weather," New York, 1923, and is the editor 

 of the recent publication "World Weather Records" {Smithsonian 

 Misc. Colls., \o\. 79, Publ. 2913, Washington, 1927).
