Mr. M. B. Rhodes’ well, near the postoffice, at Melbourne, is 
45 feet deep and furnishes a flow, which rises about three 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 materials 
penetrated in the sinking of this well were approximately as

The water is soft and very desirable for all domestic purposes. 
Another such well as the above is 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. 
The well owned by Mr. Oliver Gibbs is located at Melbourne 
Beach, across the Indian River from Melbourne. This is a four- 
inch well drilled, in 1907, by Capt. Alexander Near. It reached 
a total depth of 318 feet and is cased 100 feet. The pressure of 
the well, as indicated by the pressure gauge March 15, 1910, was 
1714 pounds. This gives the well a head of 40.4 feet above the 
surface, or estimating the surface elevation of the well to be 12 
feet above the river level, a total head of 52.4 feet above the level 
-of the water in Indian River. From an examination of a mixed 
sample from the drillings of this well, it is seen that the Vicksburg 
Limestone is reached. From Mr. Gibb’s record made at the time 
the well was drilled, it would appear that this formation was
