Probably the most important information for the general farmer 

 concerning the climate of his locality is the average temperature and 

 rainfall by months, but the following data are available for practically 

 all parts of the United States, having been compiled in 1906 and 

 published in Bulletin Q, to which reference should be made when mak- 

 ing request : Temperature by months ; mean or average ; mean of 

 maxima ; absolute maximum ; mean of minima ; absolute minimum ; 

 highest monthly mean ; lowest monthly mean ; precipitation, includ- 

 ing melted snow ; mean or average ; number of days with .01 inch 

 (one hundredth of an inch) or more ; total amount for the driest year ; 

 total amount for the wettest year ; dates on which the extreme tem- 

 peratures for the locality occurred. For northern states the dates 

 are given generally when the minimum temperature fell to -10 (10 

 below zero) or below, and the maximum rose to 90 or above ; for 

 southern states, when the minimum fell to 32 or below, and the 

 maximum rose to 95 or above.
