REMARKS. 



The month of September has been an unusual one in many respects 

 and in more than one direction a record maker for this station. 



With a smaller range of barometric pressures than has thus far 

 been recorded for September at this station, it has given us the 

 greatest number of hours of sunshine, the maximum and the highest 

 mean daily temperatures, the greatest range and the greatest and 

 least mean daily range of temperatures for September and the woi'st 

 hurricane on record at this station. 



Not only did September make a new record of " highest tempera- 

 ture " for itself, but it also established the maximum temperature 

 for the year recorded here, the thermometers registering 9 1'* and 97° 

 in the ground and observatory shelters respectively on the 23d instant. 



The storm of the 11th instant was the most notable feature of the 

 month. \Vith a normal though slightly falling barometer, tempera- 

 ture of S-f^, wind from the south-south-east, and a clear sky, sud- 

 denly, about three o'clock in the afternoon, there came from the 

 northeast a hurricane accompanied with blinding sheets of rain, 

 bright flashes of lightning, and terrific gusts of wind, reenforced by 

 a steady gale and mass of hail. For nearly twenty minutes the 

 storm fairly raged, but had spent itself at the end of half an hour 

 when the wind ceased and the sun shone brightly. 



The gale had left a record of a velocity of 93 miles per hour, a 

 sudden fall of 14*^ in temperature, from 84^ to TO'^, and an inch and 

 third of rain, fully an inch and a quarter of which must have fallen 

 in twenty minutes. Several hailstones were found by one observer 

 measuring two inches in length, and one at least one and one-quarter 

 inches in diameter. Many trees were nplit and broken by the storm, 

 standing corn was blown down, and fruit very generally blown from 

 the trees and vines. Much glass v,as broken in the plant houses 

 and considerable slate was stripped from the roof of the JMassachu- 

 setts Agricultural College Chapel. 



Other noteworthy features of the month were the extreme heat of 

 the 21st, 22(1 and 23d instants, (95°, 9.')^, and 97"" in the ground 

 shelter) and tlie heavy rain of the 2'J-3 )th instant.
