CONTROL OF TEMPERATURES BY SOLAR SEQUENCES OF VARIATION 
With this method of investigation clearly set forth, I now give 
in figures 5 to 7 results for temperatures for all months of the year at 
Washington, Albany, and Helena, and point out several characteristics 
of these curves. 
1. At every station, and in every month, the temperatures depart in 
opposite directions, attending, respectively, rising and falling solar 
activity. Thus comes about an axial symmetry of the pairs of curves 
such, for instance, as subsists with one’s right hand and one’s left. 
2. The march of the curves differs from month to month, and differs 
for the same month from station to station, yet the right and left 
symmetry always prevails. 
3. The effects are large. Differences of temperature of the order 
of 10 degrees Fahrenheit, or more, depend on whether a rising or a 
falling sequence of solar activity preceded them many days before. 
4. The effects of solar changes on temperature persist for many 
days. They may surely be traced from 8 days before to 14 days after 
the zeroth day of the solar sequence. 
5. The coefficient of correlation of these curves for the three stations 
and the 12 months of the year, and from 3 days before to 14 days 
after the solar change, is found to be r= — 61.2+1.7 percent. 
6. Since far-separated cities respond in a similar manner to the com- 
mon system of dates given in table 2, this system of dates must have 
a cosmic significance. The system of dates, in other words, betrays 
an extra-terrestrial selection, harmonious to the claim that on these 
dates changes in radiation occurred in the sun. 
SUPPORTING EVIDENCES OF SOLAR WEATHER CONTROL 
Doubters, however, may argue to the contrary as follows: 
The changes claimed in solar radiation, they may say, are so small 
in percentage that it is improbable that observation, however accurate, 
can distinguish them from accidental errors, and from the influences of 
atmospheric sources of error. May it not more probably be that the 
series of dates was selected by chance? They were, indeed, dates on 
which, in the average, large variations of temperature followed over 
periods of 17 days, but this was merely accidental. It would then 
naturally occur that sequences of dates closely following those at- 
tributed to rising solar radiation would show opposite temperature 
tendencies, since whatever goes up must come down. That far-sep- 
arated cities would react to the same systems of dates, though not identi- 
cally, is not surprising. For, as is well known, weather travels in 
waves from west toward east, so that a disturbance arrived at Wash- 
ington would have passed by stations to the west some days earlier.
