ADMINISTRATIVE REPORT I I

ditional space becomes available. The collection of fossils and minerals will be added to as rapidly as they can be properly cared for.
 LIBRARY.

 The Survey library now contains several thousand volumes, and is a fairly complete reference library for our purposes. Many volumes, particularly those of foreign Geological Surveys, are stored elsewhere temporarily owing to an insufficient number of bookcases to accommodate them in the library.

 RECOMMENDATIONS.

 CLAY TESTING LABORATORY.

 The clays of Florida should be investigated and reported upon. As is shown by the number of requests, demand for information on the properties of the clays of the State is increasing. The physical property of a clay can only be determined by proper clay testing machinery, with which the Geological Survey is not equipped. A clay testing laboratory should be installed so that a thorough, systematic investigation of the clays of the State could be made. At present space in which to install clay testing machinery is not available and the State Survey cannot make tests of clays until adequate provisions are made.

 MEASUREMENTS OF STREAMS AND SPRINGS.

 The water powers of the State should receive attention. A systematic study of these requires a knowledge of the drainage. systems, which in instances are quite complicated. Gauges should be installed on the more promising rivers and streams and records should cover a sufficient period of time to give accurate data for seasonal variations of flow.
 Likewise, the springs of the State should be gauged. In Florida are found the largest springs in the world, and estimates of flow from these should be available. Estimates of the volume of flow from many of these, particularly the larger ones, have been made at different times but it would be of considerable inter-
