 GEORG;; W. BLUEDICT.) 



There was no storm here of any kind during the days in 

 question. The whole month of March, previous to that 

 time, was remarkable here for its mild and quiet character. 

 East winds are almost never known here. Though I made 

 no record of the wind on the days mentioned in the circu- 

 lar, I am confident that the set of the air (quite slight) was 

 from the south, and the weather pleasant.
