Fuller.* It is possible that some of the small local flows ob¬ 
tained in the lake region of interior Florida are due to similar 
conditions.

ARTESIAN WATER FROM SOLUTION PASSAGES. 
Solution passages through limestones undoubtedly facilitate 
the free movement of water. If limestones should be otherwise 
relatively water tight flows might still be obtained in some in¬ 
stances from water conducted through the cavities in the limestone. 
Such possible conditions are illustrated by the accompanying 
sketch also taken from Mr. Fuller’s paper.* Several other possible 
structural conditions that may give rise to artesian flows are de¬ 
scribed and illustrated in the paper referred to. Those illustrated 
above, however, include the structural conditions which seem likely 
to prevail in Florida.

SOURCE OF ARTESIAN WATER OF FLORIDA. 
The idea is rather prevalent that the artesian waters of Flor¬ 
ida are in no sense local but are derived from the Appalachian 
Mountains or some other remote inland point. This is an error 
which if not corrected may prove detrimental. That the supply 
is local is evidenced by the fact that the artesian wells of the State 
are affected by local rains. Many of the well owners have recog-

trolling Factors of Artesian Flows.
