"We see, in looking over these tables, that nowhere where the industry 

 is most prosperous do we find that the average monthly temperature 

 during the summer months exceeds the maximum above spoken of, 70° 

 F.; nor does the average monthly rainfall appear lower than a mini- 

 mum of 2 inches during the same season. Taking the maximum average 

 temperature as here determined, 70° F., for the summer months as a 

 guide, at the same time keeping in view the average of 2 inches for 

 rainfall, I have collected in the following tables the averages of temper- 

 ature and rainfall for all the stations in the United States for which the 

 records for temperature for June, July, or August are below that figure, 

 and have caused the accompanying maps to be constructed, showing by 

 the red line the limits of the sections in which these stations are located. 

 The figures are taken from Schott's Temperature and Rain Tables, pre- 

 pared under the direction of the Smithsonian Institution. 



TABLES SHOWING THE MONTHLY AVERAGES OF TEMPERATURE AND 

 RAINFALL FOR THOSE STATIONS IN THE UNITED STATES AT WHICH 

 THE MAXIMUM AVERAGE OF TEMPERATURE IS BELOW 70° F. AND 

 THE MINIMUM AVERAGE OF RAINFALL ABOVE 2 INCHES DURING THE 

 SUMMER MONTHS.
