lation is at a minimum. It should be placed in a dry climate 

 free from fog and clouds, where the region is shielded from 

 strong diurnal winds. Similar stations to the north and south 

 of the equator, in the eastern and the western hemispheres, to 

 supplement each other, and to fill in gaps in the record 

 occurring in any station, are urgently recommended. It is my 

 belief that this subject will in the future assume large propor- 

 tions, because it is the only way at all promising in which to 

 lay the foundations for a system of seasonal forecasting. The 

 Weather Bureau has now adjusted its records to the recpuired 

 standard of observation and computation for about 100 stations, 

 and the future records will continue automatically to unroll 

 the hidden story of the sun's influence upon the earth's 

 weather and climatic conditions.
