12 FLORIDA GEOLOGICAL SURVEY-THIRD ANNUAL REPORT.
voted chiefly to an investigation of the general geology and stratigraphy of the State and the underground water supply. Bulletin No. I published in 19o8 formed a part of the results of this cooperative 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 i9o9.
During the present year co-operation has been continued in the investigation of the peat deposits. Numerous peat samples in connection with this work, have been tested during the year in the peat testing plant of the National Survey. These tests form it -.rt 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 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 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 geological 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 Survey. The Survey library now contains more than i,5oo 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. library will be appreciated.
