These heavy rains are .often.loOal, and can then have 'buhlittle in¬ 
fluence on the getieral humidity of the season, or on the stage of the 
river ; it is phlywhen! .they'bxfenff ; oVer a large district of country, that;

of March 29th and 80th last must have!been siich, as the riyer at tHil

A few remarkable faeis in cpiinectionwith the falls of rain were noted 
m examining my records. .The heaviest rains and most of them fell in 
the year 1848, between May 6th and August 15th, . when 24 inches de¬ 
scended within 38 hours,, distributed over five days. 
The severest fall of rain in the shortest time took place on August 15, 
of the same year, when in 75 minutes 5.05 inches of rain descended. 
The longest continued wet weather I ever observed here occurred in 
1845 when it rained every day from June 15 to June 28, fourteen days, 
but altogether not more than 7.91 inches.
