feet of four-inch casing, 200 feet of three-inch casing and 420 
feet of two-inch casing, and was drilled to a total depth of 507 
feet. The head did not increase with depth in this well, as is 
shown by the level of the water in either well, the head being 
three and one-half feet below the surface. 
Approximately one mile east of Rodman a flow is obtained. 
A well drilled by H. Mervin for J. P. Buie in 1909 at this point 
has a head of four feet above the surface. It is a three-inch 
well and has a depth of 270 feet. The flow as measured Decem¬ 
ber 9, 1909, is twelve gallons per minute. 
SAN MATEO. 
Flowing wells are not obtained at San Mateo, the surface 
elevation of the town, according to barometic readings, being 
approximately sixty feet above the St. Johns River. A four- 
inch well drilled for B. F. Dotney in 1900 by H. Mervin reached 
a total depth of 365 feet. The water in this well rises to within 
48 feet of the surface. A number of flowing wells have been ob¬ 
tained, however, along the river, near San Mateo.

SATSUMA. 
No artesian wells are in use at Satsuma. The water used at 
this place comes from surface sands or clays at a depth varying 
from 25 to 46 feet. Flowing wells have been obtained along the 
river west of town. 
WELAKA. 
Welaka is located on the St. Johns River, about twelve miles 
south of Palatka. Records of two wells have been obtained at 
this place. One of these is the well now owned by the Welaka 
Mineral Water Company, a three-inch well, drilled in 1906. The 
first water under pressure was encountered at a depth of 160 
feet. Below 160 feet the size of the boring was reduced to two 
inches, and was continued to a total depth of 329 feet, at which 
depth a highly mineralized water is obtained. The well has 98 
feet of three-inch casing and 213 feet of two-inch casing. The
