I02 FLORIDA GEOLOGICAL SURVEY SIXTH ANNUAL REPORT. 



with cement; 26.5 miles with gravel; .4 mile with asphalt, and 8.5 

 miles with brick. These statistics are for the year 1912, the reports 

 for the succeeding years not being sufficiently complete to justify 

 publication. It is known, however, that the total mileage of im- 

 proved roads in Florida was materially increased during 1912 and 

 1913. This applies particularly to the brick roads, several counties, 

 among which are Duval, Hillsboro, Orange, St, Johns and Seminole 

 counties, being now actively engaged in building paved brick roads 

 along the important highways of travel. 



In addition to the funds available from regular and special taxes, 

 the following counties have issued bonds for road improvement : 

 Alachua, $40,000; Columbia, $40,000; Dade, $250,000; DeSoto, 

 Punta Gorda, special district, $200,000; Duval, $1,000,000; Her- 

 nando, $300,000; HillsborO', $400,000; Jackson, $300,000; Mana- 

 tee, $250,000; Nassau, $60,000 and $180,000; Palm Beach, $200,- 

 000; Palm Beach special district No. i, $85,000, special district No.

 special district No. i, $200,000; St. Lucie, $200,000; Suwannee, 

 coupon warrants, $20,000; Walton, $70,000. In addition to the 

 regular and special annual road taxes, Florida has thus issued dur-

 dollars. 



SAND AND GRAVEL. 



The sand produced in Florida is used chiefly for building pur- 

 poses, although a limited amount is used as moulding sand. The 

 gravel produced finds its chief use for road-making and road ballast. 

 The total production of sand and gravel for 19 13 was 87,061 tons, 

 valued at $21,194.00. Of this amount 66,835 short tons, valued 

 at $11,104.00, was gravel, the balance being sand of the grades 

 mentioned. 



The companies reporting the production of sand and gravel in 

 Florida during 1913 are the following:
