Considering the subject now in another point of view, I take the number of cold days when 

 the average temperature was below zero. It thus appears that there were more such days on 

 the Grand Trunk line and the railroad lines in Minnesota than in the Rocky mountains. 



Number of winter days wJien the thermometer averaged below zero. 



The next table, showing the number of cold days during three winter months, when the 

 thermometer averaged above the freezing point, is still more favorable, showing that the number 

 was even greater at Cantonment Stevens than at Albany or Boston, while far more than at the 

 Canadian stations.
