THE ARTESIAN WATER SUPPLY OF EASTERN FLORIDA.

well shown by barometer was 22 feet above the water level in I,dian River. This would give the-well a total head of 49.7 feet above the river. The water from this well besides being used for
general domestic purposes is used for bathing and for power. Two large concrete bathing pools have been built and the waiter flows continually into them. The temperature of the water is -)aid to be 77 degress F. A water wheel connected near the well is used to pump water from a shallow, soft water well. (Pl. io, Fig. 2).
The following is an analysis of the water from this well. Anatysis-made for the State Survey in the office of the State Chemist. A. M. Henry, analyst.

Mr. M. B. Rhodes' well near the postoffice at Melbourne is 45 feet deep, and furnishes a flow which rises about tree feet above the surface. The elevation of the well is about three feet above the water level in Indian River. The well is of interest in that the water flows at such a shallow depth.

The water is soft and very desirable for all domestic purposes.
Another such well as the above is one owned by Dr. L. A. Peek. This well is 52 feet deep, one and one-fourth inches in diameter and furnishes a good supply of soft water.
