A comparison of the mean annual temperatures for Sunnyside 

 (47.1 ) and Pocomoke City (58.0°) shows a difference of 11° be- 

 tween these most widely separated stations. That the difference be- 

 tween the means for Sunnyside and Boettcherville (5.3°) is greater 

 than that between any other two stations is to be attributed to the 

 greater difference of altitude and to the influence of the main ridge 

 of the Alleghanies upon the prevailing north-west winds of the winter 

 months. The difference in the mean temperature between Green 

 Spring Furnace and Easton is only 2°. The difference of 3° between 

 Easton and Pocomoke City is to be attributed to the nearness of the 

 latter station to the ocean, as well as to the presence of a large body 

 of water to the west of it, and to its more southerly location. 



The annual mean maxima exhibit about the same relation as do 

 the annual means, — that is the differences between Sunnyside and 

 Boettcherville (7.8°) and between Easton and Pocomoke City (2.7°) 

 are greater than the entire difference between Boettcherville and 

 Easton (1.9°). The difference between the annual mean minima of 

 Sunnyside and Pocomoke City is 13.1°, as contrasted with a differ- 

 ence of 8.6 between their mean maxima, indicating a greater differ-
