CLIMATE OF LOWER DIVISION OF COAST PINE BELT. 



Ill 



a height of from 220 to 300 feet above the flat woods and marshes and 

 alluvial forests of the tide- water region. Where the level table-lands, 

 devoid of surface drainage, are underlaid by impervious clays, spongy 

 bogs surround the heads of water courses. On the rolling uplands 

 with a porous siliceous soil the copious rainfall is readily absorbed, 

 giving rise to innumerable springs, the feeders of the numerous limpid 

 brooks and creeks by which this region is traversed. The area of the 

 lower pine region is estimated to embrace a little over 7,000 square 

 miles, including the following counties and parts of counties: Geneva, 

 part of Covington, Escambia, part of Monroe, and all of Baldwin, 

 Mobile, and Washington. 



Both the climate and topography of this region exhibit great uni- 

 formity. Under the moderating influences of the proximity of the 

 sea, the climate is generally mild. According to the records of the 

 Mobile station of the United States Weather Bureau, extending over 

 a period of twenty-three years, the mean annual temperature for that 

 period was 66.9, with the highest temperature 101, observed in 

 July, 1884, and the lowest 11, in January, 1886. *
