EEPORT OF METEOROLOGIST. 



LEONARD METCALF. 



Aside from the mere routine work incident to keeping up 

 the daily meteorological records and observations, the work 

 of the department has been confined chiefly to the compila- 

 tion of data accumulated at this observatory during the past 

 seven years. The records of this station, from the time of 

 its foundation in 1889 to date, have been compiled and sum- 

 marized, and tables have been prepared showing the maxi- 

 mum, minimum and mean observations. These results will 

 probably be published in the form of a special bulletin early 

 next year. 



But few new instruments have been added to our equip- 

 ment, — one or two new clocks for the self-recording in- 

 struments replace the old ones in case of emergency or 

 mishap, and thus preserve the continuity of the records ; 

 and a new signal service standard Fahrenheit thermometer, 

 for comparing and verifying the accuracy of the temperature 

 indications of the wet and dry bulb thermometers, and the 

 maximum, minimum and self-recording thermometers. 



The ozone observations have been discontinued, owing to 

 their uncertainty and unreliability. The amount of rainftill 

 will henceforth be recorded on top of the tower, as on the 

 ground, by means of a United vStates signal service standard 

 rain gauge (as well as by the self-recording gauge), in order 

 that the tower readings may be perfectly comparable with 

 those of the ground.
