FLORIDA GEOLOGICAL SURVEY—THIRD ANNUAL REPORT. 
voted chiefly to an investigation of the general geology and strat¬ 
igraphy of the State and the underground water supply. Bulletin 
No. i published in 1908 formed a part of the results of this co¬ 
operative work. A special report on the stratigraphy of the State 
forming a second part of this co-operative work was published in 
the Second Annual Report in 1909. 
During the present year co-operation has been continued in the 
investigation of the peat deposits. Numerous peat samples in con¬ 
nection with this work, have been tested during the year in the 
peat testing plant of the National Survey. These tests form .1 part 
of and are included in the report on peat deposits. Through this 
generous co-operation on the part of the National Survey the State 
Survey is able to publish at this time a much more complete report 
on the peat resources of the State than would otherwise have been 
possible. The constant co-operation and advice in connection with 
this work given by Professor Charles A. Davis, in charge of peat 
investigations for the National Geological Survey, is especially ap¬ 
preciated. 
The State Department of Agriculture:—The Survey law pro¬ 
vides 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 of Chemistry 
of the Department of Agriculture and in so far as the work of the 
Survey contributes to agricultural interests, to the Department of 
Agriculture as a whole. 
The State Agricultural Experiment Station:—In its study of 
the water supply in relation to agriculture, of soils in their geo¬ 
logical relations, and in other ways, the work of the State Survey 
may be expected to supplement certain lines of work of the State 
Experiment Stations, the two organizations being of mutual aid to 
each other. 
THE SURVEY LIBRARY. 
A well-equipped reference library is essential to the best results 
and an effort is being made to bring together those publications 
which are necessary to the immediate and future work of the Sur¬ 
vey. The Survey library now contains more than 1,500 volumes. 
These include the reports of the several State Geological Surveys; 
the Annual Reports, Bulletins, Monographs, Professional Papers, 
Water Supply and Irrigation Papers, and other publications of the 
National Geological Survey; the reports of the Canadian, and a few 
other foreign Geological Surveys; and many miscellaneous volumes 
and papers on geological subjects. Additions to the Survey lib¬ 
rary will be appreciated.
