INTRODUCTION. 



The present number of the UNIVERSITY OF MAINE STUDIES is 

 a compilation from various sources. From January i, 1869, to 

 January i, 1893, a series of meteorological records was kept at 

 Orono, Maine, by Dr. M. C. Fernald, ex-president and sometime 

 professor of physics at the University of Maine. Since that 

 time the records have been continued by Drs. W. H. Jordan 

 and C. D. Woods, former and present directors of the Maine 

 Agricultural Experiment Station. These results have been aver- 

 aged and tabulated by the author and are discussed in this 

 paper. 



A series of observations on precipitation has been carried on 

 by Prof. H. S. Boardman, of the department of civil engineer- 

 ing, from 1900 to 1906 inclusive, and the results of these obser- 

 vations are printed here. 



The work bearing upon the evaporation of snow and ice, and 

 of liquids, was performed in the department of physics by Mr. 

 F. C. Mitchell and Miss M. C. Rice. The matter used here is 

 reprinted from the Monthly Weather Review. 



Acknowledgment should be made to Prof. L. H. Merrill of the 

 Experiment Station, and to Mr. S. L. Boardman of the Bangor 

 Commercial for data supplied to the author; and to various 

 students of the University for clerical work.
