mean values -svliicli are taken for the normals of the station. 

 It should again be published when the records for twenty 

 years are completed. 



The usual monthly bulletins have been issued, and the one 

 for December will contain a summary of the records for the 

 year. The station has also furnished the Boston office of the 

 United States Weather Bureau with the monthly voluntary 

 observers' rej)orts, and has arranged to send weekly snow re- 

 ports during the winter season. 



The local forecasts are received by telegraph daily, Sun- 

 days excepted, from the Boston office, and the proper flags 

 are displayed. 



During the year a new Draper self-recording thermometer 

 was purchased, to replace the one in use. A new maximum 

 thermometer of standard pattern was purchased, to replace 

 the one in use which was broken in resetting. A Felt and 

 Tarrent comptometer has been added to the equipment, and 

 is used in making many of the computations. All computa- 

 tions are checked, to reduce the probability of errors to a 

 minimum. 



In February ]\Ir. C. IT. Chadwick, the observer, retired 

 to accept a position in civil engineering in the south ; and the 

 assistant observer, Mr. T. A. Barry, was advanced to the 

 place.
