Duration of Dry and Wet Periods. 



The distribution of rainfall in ]\rarvland is so uniform that drous;hts 

 are never of long enough duration to cause an entire failure of crops, 

 though they have frequently been long enough to materially reduce the 

 yield, and to cause the failing of wells in country districts. Long periods 

 of fair weather are usually considered a favorable climatic feature, at 

 least they are agreeable to people whose occupation is not farming until 

 the dust becomes objectionable. Periods of dry and wet weather are 

 climatic elements of much interest. Below are given the dates of all 

 periods during which no appreciable precipitation fell at Solomons for 

 10 or more consecutive days, and also the rainy periods of 5 days or 

 more, with the total rainfall during each:
