THE ARTESIAN WATER SUPPLY OF EASTERN FLORIDA.

MANDARIN.
Mandarin lies within the flowing area which borders the St. Johns River. Several wells have been put down in this section. A well near Mandarin drilled by H. Walker for J. D. Mead reached a total depth of 6oo feet. This well is cased 377 feet and the water is reported as rising 6o feet above the surface.
MAXVILLE.
Maxville is located on the Seaboard Air Line Railway near the southwestern corner of' Duval County. The elevation at this point is according to the profiles of the railroad, about 93 feet above sea. A well drilled at this place in 19o2 for Mr. R. V. Douglass is reported to have reached the depth of 650 feet. This well is non-flowing.
'T. JOHNS COUNTY.
LOCATION AND SURFACE FEATURES.
St. Johns 'County lies in northeastern Florida bordering the Atlantic Ocean. On the north it joins Duval County and on the south Volusia County. The western boundary is formed by the St. Johns River. The county has a total length of sixty miles. In width it varies from eighteen to twenty four miles. The total area is approximately iooo square miles.
Owing to the location of St. Johns County between the St. Johns River on the west and the Atlantic Ocean on the east no great variation in elevation is to be expected. It is probable, however, that small areas in the interior of the county lie above the fifty foot contour. In passing from St. Augustine to Jacksonville, levels made by the Florida East Coast Railway show near the county line an elevation over a small area, of 57 feet. The greatest elevation recorded between St. Augustine and Hastings is in the vicinity of Hurds. A line of levels run from the coast at St. Augustine at the instance of Mr. B. A. Carter, gave for Hurds an
elevation of thirty eight feet. Levels obtained from the U. S. Engineers' Office, Jacksonville, Florida, give for a point a short distance east of Hurds a level of thirty-six feet. From East Palatka south, information regarding elevation is unfortunately very deficient. From the fact that such wells as have been put down at Dinner Island, Espanola, Bunnell and Dupont are non-flowing, it is probable that this part of the county is above the twenty fiee
