Remarks. 



The weather conditions during the month of September, 

 1893, were influenced by seven cyclones and nine anti- 

 cyclones. Five of the cyclones passed north of us down 

 the St. Lawrence valley, one across central New England 

 from west to east and one up the coast east of us. 



The storms were not severe with possibly the exception 

 of the thunder-storm of the 7th. A very heavy wind accom- 

 panied this storm, and considerable damage was done in the 

 eastern part of the State and in the vicinity of Providence, 

 R. I. At Boston the wind velocity increased in five minutes 

 from sixteen to forty miles per hour, with a maximum 

 velocity of forty-four miles. 



The temperature during the month was considerably below 

 the normal, and the precipitation was also deficient. 



The storm of the 29th was accompanied by light snow in 

 the Berkshire Hills. At Pittsfield the snow began at 7.40 

 a.m. and continued for about half an hour. The flakes were 

 large and rain fell at the same time. The driver of the 

 Williamstown and Pittsfield stage states that in the vicinity 

 of New Ashford the snow was about three inches deep. Of 

 course it melted in a very short time. 



The last part of the month was unsettled, but no general 

 storm occurred. 



The crops are about all harvested, and are reported in 

 good condition generally.
