CLIMATE OF LOWER DIVISION OF COAST PINE BELT. 111 
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."
