THE ARTESIAN WATER SUPPLY OF EASTERN FLORIDA.

Aside from the superficial soil and sand the material penetrated 
at Hastings to a depth of about 170 feet consists largely of clays 
although some water bearing sands are reported and a shell stra¬ 
tum at a depth of 60 to 62 feet is specially mentioned. 
At a depth of 170 to 180 feet a dark colored, very hard stratum 
occurs. This rock appears from the well records to be similar in 
character to the rock found at St. Augustine at a depth of 170 
to 180 feet. After passing through this stratum the wells pene¬ 
trate limestone consisting of alternating hard and soft strata, the 
flow increasing as each hard stratum is penetrated. This lime¬ 
stone probably representing the Vicksburg group has been pene¬ 
trated at Hastings at about 200 feet or to a total depth of 365 feet. 
Of the many wells at Hastings it is possible to give an individ¬ 
ual record of only a few. The following is a log of the well of 
F. R. Allen, kindly supplied by the driller, Mr. H. Walker. This 
is a 6-inch well located 3 miles southeast of town. It was drilled 
in May, 1908 and is used for irrigating purposes.

The following is a partial log of the well of Henry Bugbee 
taken from the notes kept by I. C. Peck. This is a four-inch well 
drilled in 1902 and located two and one-half miles south of Hast¬ 
ings. The well has a total depth of 257 feet and is cased 178 
feet. Tt is used for irrigating purposes.
