supply of central Florida accompanies this report. 
Co-operation with the National Geological Survey. 
The State Geological Survey has fortunately been able 
to co-operate during the year with the National Geological 
Survey. This co-operative work, planned soon after the 
organization of the State Survey, includes a detailed in¬ 
vestigation of the stratigraphy and underground waters 
of the State, and has been carried on throughout the year 
in accordance with the original plans. The State Survey 
has profited very greatly by assistance from the National 
Survey and by the presence of members of the National 
Survey in the field. Moreover, the State has had the bene¬ 
fit of a much more extended geological investigation than 
would otherwise have been possible. The results of these 
investigations will be embodied in a special bulletin on 
the stratigraphy and general geology of the State and in 
reports on the underground water supply. 
Relation of the Survey to Other Organizations. 
Geological Surveys of Neighboring States:—Geological 
formations are limited by no such lines as State bound¬ 
aries, and an intelligent study of a formation often neces¬ 
sitates a knowledge of its extent and development in a 
neighboring State. The relationship of a State Survey is 
therefore close with neighboring States, and particularly 
with adjoining States. This relationship in the case of 
the Florida Survey is especially close with Georgia and 
Alabama. With more distant States there is a no less 
real relationship growing out of a similarity of deposits, 
and of methods of study and development. 
Office of State Chemist:—The Survey law provides that 
analytical work necessary to the investigations of the 
Survey shall be done by the State Chemist. The Survey is 
thus brought into co-operative relation with the Division
