addressing- the chief of the Weather Bureau, Depart- 

 ment of Agriculture, Washington, D. C. They are 

 published in pamphlet form, along 1 with tables giving- 

 dew point temperatures. Observers must work out 

 the small fractions for themselves, if they think 

 necessary, but results within the limits covered by 

 the table are near enough for present practical pur- 

 poses. 



It is of no use to test for moisture unless having* 

 the ability to control it, any more than a thermometer 

 would be of use unless the means of regulating* tem- 

 perature were at hand. Humidity can be controlled 

 by ventilation and the use of absorbents, which are 

 considered elsewhere.
