on the north and St. Lucie 'County on the south. Aside from the 
line of sand dunes running parallel with the coast this county is 
prevailingly of the palmetto flatwoods type of country, although 
extensive prairie and muck lands occur in the interior of the 
county. Lake Washington, in the central part of this county, 
has an elevation of 15.74 feet while Lake Wilmington, the head 
waters of the St. Johns River, in St. Lucie County, has an eleva¬ 
tion of 23.3?'' feet above mean sea level at Indian River Inlet.* 
WATER-BEARING FORMATIONS. 
The deep wells in Brevard County enter the Vicks'burg Lime¬ 
stone. At Melbourne this limestone, as indicated by well samples 
kept from the well of Mr. Oliver Gibbs, was reached at the depth 
of 221 feet. At Cocoa, in the well of Mr. H. Bradford, the Vicks¬ 
burg Limestone was recognized at a depth not exceeding 190 feet. 
AREA OF ARTESIAN FEOW IN BREVARD COUNTY. 
Although the interior of this county is but thinly settled and 
but few wells have been put down, it is probable that the greater 
part of this county lies within the area of artesian flow. On the 
high sand dune ridge, which lies out three or four miles from the 
•coast, a flow is not to be expected. This is probably also 1 true of 
points within the interior of the county, particularly in the south¬ 
western part.
