2IO FLORIDA GEOLOGICAL SURVEY I3TH ANNUAL REPORT 



larly in our Seventh Annual Report (pp. 142-144), so that httle 

 more needs to be said about it here. 



Fig. 38. Typical scrub, witli bare white sand in foreground, about three 

 miles east of Tavares, Lake County. Feb. 21, 1909. 



The dominant and almost the only tree is the spruce pine (Pinus 

 claiisa), and there is an undergrowth of evergreen shrubs ^and 

 small trees, averaging about the height of a man, and very little 

 grass or other herbage. The density of the forest varies consider- 

 ably in different places. On the old dunes of the east coast, and in 

 a few places in the interior (see Seventh Ann. Rep., fig. 62*) the 

 pines are so close together as to make a moderately dense shade; 

 and the U. S. Geological Surv^ey's Ocala topographic sheet (used 

 as a part of the base-map for the soil survey of the "Ocala area.'' 

 reprinted in our Seventh Annual Report) shows an area over a mile 

 in diameter about three miles west-southwest of Ocala, labeled 

 "dense scrub," through which no contour lines were run. ^ut in 

 the lake region it is often so open that large areas of dazzling white 

 sand can be seen, and such places are delightful to stroll through, 

 being so bizarre in appearance and so clean and free from briers, 

 snakes, mosquitoes, etc. 



*The same cut was used previously in the Popular Science Monthly (now 

 called the Sciei^ific Monthly), vol. 85, p. 358, Oct., 1914.
