K'OTE.— The data for this 

 Gilligan, U. S. signal ofi&cer, 



table are derived from tlie meieorological summary furnished by J. J. 

 Denver, Colo. 



TEMPERATURE. 



From the physical nature of Colorado we must expect a low average 

 temperature. The mean annual temperature at Denver is 49 degrees, 

 about the same as at Chicago and Boston j but it is actually more ex- 

 treme than this would indicate, for we also find that the lowest point the 

 thermometer reached was 29 degrees below zero, and the highest point 

 was 105 degrees. But these extremes are few and of short duration, and 

 the records of the maximum and minimum temperature will be a better 

 indication for this region than for many others. More often than this 

 severe cold will come soft, balmy days in midwinter, when wraps are 

 cast aside and the houses are thrown open in the genial sunshine. 



In comparing the records of each season here witli those of other 

 parts of the country, we find that the average temperature is more 

 equal here tluroughout the year. We have the winter temperature of
