About 88% of the trees and still more of the shrubs are ever- 

 green. Plants of the heath family are less abundant here than in 

 some other flatwoods regions that have less fertile soils. . The pines 

 have been very largely exploited for lumber and naval stores, as 

 usual. ' 



Population. A rough approximation of the population condi- 

 tions may be arrived at by subtracting the figures for Tampa and 

 West Tampa from those for Hillsborough County (which included 

 Pinellas up to 191 1). On this basis there were in 1910 nearly 25 

 inhabitants per square mile, 12.8% of them in cities of over 

 2,500 population, 71.6% native white, 8.6% foreign white, and 

 19.7% negroes. (The foreign whites included a few hundred 

 Greeks at Tarpon Springs, which is in a different region, and now 

 in a different county.) In the population over 10 years old 1.7% 

 of the native whites. 19.9% of the foreign whites, and 19% of 

 the negroes were illiterate. 



Excluding Tampa, which belongs partly to a different region, 

 and West Tampa, which is separated only by an imaginary line, 

 the largest cities and towns in 191 5 were St. Petersburg, with 

 7,186 inhabitants: Bartow, with 3,412; Plant City, 3,229; Fort 

 Meade, 2,150; Mulberry, 1,121; Port Tampa City, 1071 ; Largo, 

 552; and Bradley, 295. The returns from the 1920 census, as far 

 as available, give these places the same relative rank, and St. Peters- 

 burg nearly double the population. But these figures should be 

 used with some caution, for St. Petersburg is one of the most pop- 

 ular winter resorts in Florida, and the 191 5 census was taken in 

 July and that of 1920 in January. Oldsmar, in the eastern edge 

 of Pinellas County, which was not on the map at all in 191 5, may 

 be larger now than some of the places listed. 



Agricultnre. The flatwoods region includes less than half of 

 Pasco and Polk Counties, and Pinellas did not exist in 1910, so 

 that the best we can do for agricultural statistics is to use the 

 figures for Hillsborough County. A considerable part of that be-
