16 FLORIDA GEOLOGICAL SURVEY-I3TH ANNUAL REPORT

can not be placed on the importance of saving samples of the drillings from all the deep wells that are drilled for whatever purpose. These. should be carefully collected at frequent intervals regardless of whether there is a change in the formation or not and properly labeled as to the depth from which they were taken.
 Of interest in consideration of the subject of oil in Florida is a Press Bulletin of the United States Geological Survey which appeared during April 1920. This bulletin relates to Peninsular Florida, in fact that portion of the State lying from Suwannee County eastward. The title as first published is misleading in that it includes the entire State but from the subject matter it is readily seen that the area lying from Suwannee County westward is not treated. The bulletin referred to is herewith republished with the insertion of the word "Peninsular" in the title.:


 DRILLING FOR OIL IN PENINSULAR FLORIDA.

 ADVICE GIVEN BY GOVERNMENT GEOLOGIST.

 Wells have been drilled for' oil in every State in the Union except the New England States and possibly four others-North Carolina, South Carolina, Nevada, and Idaho. Only sixteen states, however, can be called oil-producing. A number of deep wells have been drilled in Florida, the deepest being one near Bushnell, in Sumter County, which was carried to a depth of 3,080 feet. This well and one near Waycross, in southern Georgia, which was drilled to a depth of 3,045 feet, are two of the deepest wells in the Atlantic Coastal Plain.

 GEOLOGISTS NOT HOPEFUL OF SUCCESS.

 Although the deep wells drilled in Florida have yielded no indications of oil the interest in the possibility of finding oil there has not been diminished by their failure but has actually increased with the increase in the prosperity of the State., so that much money has been spent in drilling test wells in areas where oil is not likely to be found. As additional wells will no doubt be drilled in Florida the results of geologic field work done by 0.
