incident to the collection, and to the making of such returns by the pro¬ 
ducers, is avoided; and the arrangement, in the main, has been found 
satisfactory. This method also brings about uniformity in the totals 
of the several industries, which might not be the case if the statistics 
were collected independently. 
Co-operation with the United States Geological Survey could be car¬ 
ried on very advantageously to a greater extent. Subjects of real im¬ 
portance and worthy of consideration in this respect are topographic 
mapping and a report on the water powers of the state. To enter into 
this, however, requires an increase in available funds. A suggestion as 
to the advantage of such method is the fact that the Federal Survey 
will co-operate upon a basis of equal expenditure of funds. 
CO-OPERATION WITH OTHER DEPARTMENTS 
A few years ago, in co-operation with the United States Bureau of 
Soils, surveys were made of some of the counties of the state. Termi¬ 
nation of this co-operation was forced through a lack of funds. There 
is a demand, however, for a continuation of the work. And the Bureau 
of Soils will bear one-half of the expense of such investigations. 
Co-operation with certain of our own state departments would prove 
mutually advantageous. The large amount of limestone, marl and clays 
used in building many of the roads now under construction suggests 
the desirability of making detailed reports on these materials and indi¬ 
cates the possible usefulness of such information to the State Road De¬ 
partment. An investigation of the sands and gravels of the state would 
also be of importance to those having in charge the problem of road 
building in Florida. 
The relation between the State Geological Survey and the State De¬ 
partment of Agriculture is shown by some of the reports that have been 
prepared by the former; for instance, one dealing with the origin of 
the soils of the state, and others describing the native timber growth, 
the vegetation in detail and its relation to the soils and to the geology of 
the several geographic regions. Reports have been prepared by mem¬ 
bers of the Geological Survey for use of the Department of Agriculture. 
With the Florida State Board of Health the Geological Survey might 
co-operate. This is particularly apparent in the matter of an investiga¬ 
tion of the underground water supplies of the state.
