rainfall, and this cycle ends in 1903. 60 + 1843 = 1903 which (if the theory is 

 correct) should give us a plus from the Jupiter cycle. And again, two revolutions 

 of Saturn starting at the same time also, end in 1903 ; so from this theory we 

 should get 43 inches of rain next year. But all the other planets must have an 

 influence of like kind ; and to follow all the changes is beyond my power, and I 

 give it up ; but I still think that it will be done by some future meteorologists, and 

 I wish our Mr. Stupart and other workers ultimate success.
