REPORT OF METEOROLOGIST. 



President Fernald, Meteorologist to the Station. 



MAINE EXPERIMENT STATION. 



Lot, 44°, 54', 2", N. Long, 68% 40', 11", W. 



In the meteorological work undertaken by the Experiment Sta- 

 tion, the object sought is not so much the observing and reporting 

 of general atmospheric phenomena as the careful study of the 

 special meteorological conditions which are more or less intimately 

 connected with practical agriculture. 



A reliable determination of these conditions from which safe 

 deductions can be made, necessarily involves observations con- 

 tinued through a series of years. 



Accordingly in commencing the work of observation, a plan 

 was formed which has been strictly adhered to during the past 

 three years. 



This report contains a summary of results afforded by about 

 thirty thousand independent observations. Under each division 

 of the subject here considered, the observations of the past year 

 are continuous to those of the two preceding years. 



Since the instruments have remained unchanged in position dur- 

 ing the three years under notice, I draw freely from my former 

 reports, in presenting the arrangement of instruments and the 

 other needful descriptive or explanatory data. 



The most of the instruments employed were manufactured by 

 H. J. Green of Brooklyn, N. Y. Mr. Robert H. Fernald of 

 Orono, has been observer during the three years that this work 

 has been carried on. In this report the results of observations 

 made during the years 1889, 1890, and 1891, are combined. 



The several problems considered appear in definite order, in the 

 following pages. The first to which attention has been given, is 

 a determination of .the percentage of moisture in forest as com- 

 pared with that in open field. 



The arrangement of instruments for this investigation is here- 

 with submitted.
