METEOROLOGICAL RECORDS 



173 



March 5th, 1908, there occurred the heaviest rainfall of that year. 

 The maximum and minimum curves almost touch. The middle of 

 April and late September, 1909, are other illustrations. The rela- 

 tionship is so striking that I have put the two curves side by side 

 and have had them drawn to the same scale.
