VI NOTE 



observing solar radiation, in order that, by combining the results of 

 all of them, well-founded mean solar radiation measurements may be 

 available every day in the year, and for a sufficient succession of 

 years, so that quantitative studies of the dependence of weather con- 

 ditions on solar variations similar to those of Mr. Clayton may be 

 advantageously pursued. 



Plans are now on foot to transfer the Smithsonian station in South 

 America to the care and support of the Argentine Government. If 

 these plans go through, the Smithsonian Institution, it is hoped, will 

 be enabled to maintain an observing station in Egypt. With the aid 

 of the United States Weather Bureau, investigations are now being 

 made to select the most suitable possible site in the United States in 

 the hope that our government may be persuaded to equip there a third 

 solar radiation observing station, to be operated the year round. Thus 

 it may be that sufficient solar observations will be obtained ; but it is 

 gratifying to know that great interest is felt in the matter of equip- 

 ping another station in Australia, and it is possible that a fourth 

 station may be obtained there.
