TILLMAN.
The only deep well at Tillman of which record has been obtained was drilled by John Mc Allister in 189o and is owned by R. A. Conkling. It is 350 feet deep and furnishes an excellent flow of water which is used for general domestic purposes.
TITUSVILLE.
Titusville, the county seat of Brevard County, is located on the Indian River. Several artesian wells have been sunk at this locality, but up to the present time principally salt water has been obtained. A test well put down about 189o was drilled to a total depth of 864 feet. A salt water stratum was reached at a depth of about ioo feet. The well was cased to a depth of about i io feet, but no attempt was made to case off the salt water. Both the flow and the head is reported to have increased with increase of depth. Several other wellshave been subsequently drilled in and near the city. One of these located at the Dixie Hotel is said to have been drilled to a depth of about 400 feet. Another located at the Grand View Hotel, drilled about I895, is believed to have reached the depth of about 200 feet. Two other wells, one located at the old plant of the Florida Extract Company,' the other at the plant of the Titusville Ice Company were drilled to a depth of 15o and I45 feet respectively. Salt water was obtained from all of these wells and in none of
