As will be seen in the above analysis this water contains a high 
percentage of sodium and chlorine. The water tastes brack¬ 
ish and is used for cooling purposes in the manufacture of ice. 
The principal water supply for domestic purposes in and around 
Ft. Pierce is obtained from shallow wells ranging in depth from 12 
to 50 feet. 
NARROWS. 
Two deep wells are reported from Narrows. One is owned by 
Mr. F. Foster, the other by M r. E. L. Gray. These wells were drill¬ 
ed by Mr. W. J. Nesbitt about the year 1892. Both are three inches 
in diameter and 420 feet deep. The height to which the water would 
rise above the surface was not obtained but the wells are reported 
to have a head of several feet and to furnish a strong flow of 
water. 
ORCHID. 
Mr. S. K. Michael owns an artesian well at Orchid. This well 
was sunk by Capt. Alexander Near in 1896. It is 480 feet deep, 
four inches in diameter and is cased 85 feet. The well is reported 
to have a head of 40 feet above sea, and to furnish an abundant 
supply of hard, sulphur water. 
ROSELAND. 
The artesian wells at Roseland have been drilled for a number 
of years and for this reason no very definite information could be 
obtained. Mr. L. C. Moore owns three wells located about one and 
one-half miles north of Roseland on the point between the Sebas¬ 
tian and Indian Rivers. These wells range in depth from 350 to 
453 feet. The water is hard and impregnated with hydrogen 
sulphide and is used for irrigating and general purposes.
