THE ARTESIAN WATER SUPPLY OF EASTERN FLORIDA.

equivalent to a head of 55.44 feet above the surface. The temperature of the water is given as 92 degrees F. and the flow as 225,ooo gallons per day.
Among the isolated flowing wells in the State two at Graceville in Jackson County are of especial interest. The first well at this locality was drilled some years ago by Mr. F. J. White. When first drilled, Mr. White says, the well flowed slightly above the surface, but soon afterwards ceased to flow. On the day following the great San Francisco earthquake of 19o6, however, the well was observed to be flowing, and it has continued flowing from that date. The second well at Graceville was drilled in IgIO for the city by Mr. C. D. Williams. This well is 287 feet deep. The water has a head sufficient to rise about 2 feet above the surface. The well is eight inches in diameter for 161 feet, and six inches to the bottom. The flow is estimated at 2o gallons per minute. Although no well samples have been obtained it seems probable from the driller's notes that the wells at this locality pass through the Vicksburg Limestone and enter an underlying formation.
At Perry in Taylor County flowing water has been obtained recently at a depth of 1199 feet. The water from this well, how-ever, is too salty for use. The total dissolved solids in this water as shown by analysis made by the State Chemist is 5650 parts per million parts water. The chlorine alone amounts to 590 parts per million parts water. A similar deep well near Crystal River in Citrus County was reported with an analysis of the water in the bulletin on the water supply of central Florida published in 19o8.
A well drilled as a test well for oil about six miles south of Chipley in Washington County is said to have flowed at a depth of about 1250 feet.
