A PRELIMINARY REPORT ON CLAYS OF FLORIDA 245

ing is done by throwing. No blends are used. The product, which is sold locally, includes hand-decorated vases, candle-sticks, curios, etc. The ware is burned in a small up-draft kiln.
 With the exception of the sedimentary kaolin and the fuller's earth, no raw clays are mined in Florida for shipment to points outside the State. For a discussion of the sedimentary kaolin, see Chapter Ix.
 PRESENT TENDENCIES
 General Development and Expansion in Florida-The growth and development of the industries of Florida during the past few years has been phenomenal. This expansion is perceptible in every industry in the State and is closely related to the general development and improvement which has been taking place in all the Southern States. The magnitude of Florida's industries may be determined from the following table of production in the year 1920:
 Agriculture ........................................... $150,139,749.00
 M inerals .............................................. 20,000,000.00
 Forest Products ........................................ 25,000,000.00
 Fisheries ............................................. 20,000,000.00
 M anufacturing ........................................ 150,000,000.00

 Of these industries, agricultural, including horticultural pursuits, are of chief importance, and are the ones most likely to continue to expand. Of 35,111,040 acres of land in the State and of which, it is claimed, approximately 85 per cent is capable of cultivation, only 17.2 per cent is now in farms and only 6.5 per cent is classed as improved land. Not all of this is actually cultivated.
 The mineral production consists chiefly of phosphates, fuller's earth, lime and sedimentary kaolin, with a few other products playing a minor part. The mineral industry of the State is not likely to greatly increase, unless now unknown products are discovered, but will probably remain at about the same point for some time in the future as in the past ten years.
 While Florida is not regarded as a manufacturing State, the value of its manufactured products at present equals the value of the agricultural products. The manufacturing industries in the State are capable of, and likely to be, greatly increased in the coming years. There is a decided tendency for many manufacturing concerns to move to
