The mean temperature for each month shows that the maxi- 

 mum occurred in July, 67.40, and the minimum in January, 

 16.09. This latter is contrary to the prevailing opinion regard- 

 ing Maine temperature, as February is generally regarded as 

 the coldest month. When the monthly means are plotted, the 

 curve has the general characteristics of curves of this class 

 plotted by o'ther observers. See, for example, Loomis's Treat- 

 ise on Meteorology, p. 31, where is plotted a like curve for New 

 Haven, covering a period of eighty-six years. The similarity 

 of the two curves is striking. 



DAILY PRECIPITATION AND THE ACCUMULATION 

 OF PRECIPITATION. 



The following tables and curves show the amount of rainfall 

 at Orono, Me., for each day from January i, 1900, to January I, 

 1907, and the total for each year from January I to the given 

 time. 



The accompanying curves show the mean monthly accumula- 

 tion of rainfall for the years 1900, 1901, and 1905. The first of 

 these years was- characterized by an excess of precipitation, the 

 second by a normal amount, and the third by an unusual scarcity. 



The monthly mean accumulation curve was obtained by aver- 

 aging the results obtained from the Experiment Station extend- 

 ing over a period of 35 years.
