 when the twelve months are summed together. In so long an 

 interval as 365 days, the oscillations due to the passage of 

 cyclones and anticyclones, whether they are strong or weak in 

 type, nearly balanced each other about the normal value. If 

 there is a small annual excess it means that many colder waves 

 have passed over the United States, and if there is a small 

 annual deficiency, that more warm waves have passed over the 

 country. The annual departure is a guide to the interpreta-
