210 FLORIDA GEOLOGICAL SURVEY-I3TH ANNUAL REPORT

larly in our Seventh Annual Report (pp. 142-144), so that little more needs to be said about it here.



















 Fig. 38. Typical scrub, with 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 clausa), 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 considerably in dif ferent places. On the old dunes of the east coast, and ini 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 Survey'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. But 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, 1)eing so bizarre in appearance and so clean andl free from briers, snakes, mosquitoes, etc.

 *The same cut was used previously in the Popular Science Monthly (nowv called the Scicutific Monthly), vol. 85, p. 358, Oct., 1914.
