ADMINISTRATIVE REPORT 9

 RESIGNATION OF E. H. SELLARDS AS STATE GEOLOGIST.

 After serving the State of Florida for almost fifteen years, three years as Profe.ssor of Geology and Zoology at the University of Florida and practically twelve years as State Geologist, Dr. E. H. Sellards tendered his resignation which became effective April 18, r919. Dr. Sellards did not leave the services of the State without regret, for the work was most attractive, the field of labor and investigation' rich and the associations formed in the prosecution of the great work that he had accomplished most pleasant. It was, however, the mounting cost of the daily necessaries and comforts of life with the decreasing purchasing power of the dollar that was the compelling force and deciding factor in the acceptance of a more attractive offer with the Bureau of Economic Geology and Technology of the State of Texas. No one was more familiar with the geology of the State of Florida and its economic resources than was Dr. Sellards and in his leaving the State has lost the services of a most thorough, painstaking, conscientious and scientific investigator.
