led all other states in 1919, with a production valued at $1,779,550, which 
was 19.8 per cent of the total value of mineral products for the state and 
88.1 per cent of the value of all fuller’s earth produced in the United 
States in 1919 ($2,019,226). 
“The other mining industries, clay, limestone, and the recovery of rare 
metals from beach sands, were unimportant. 
“A small amount of development work on non-productive mining 
property was reported by one operator in Florida in 1919. 
“The relatively large number of small enterprises as determined by the 
average number of wage earners employed is shown in Table 3. Of 
the total number of mining enterprises in 1919 in Florida, 72.3 per cent 
were in classes having less than 101 wage earners and such enterprises 
employed only 33.6 per cent of the total number of wage earners. On 
the other hand, enterprises employing more than 100 wage earners con¬ 
stituted 27.8 per cent of the total number of enterprises and employed 
66.4 per cent of the total number of wage earners. These larger enter¬ 
prises were all in the phosphate rock and fuller’s earth industries. 
“The statistics for wage earners given in Table 4, showing the changes 
in the number employed, month by month, reflect conditions prevailing 
in the industries during the census year. 
“Table 5 presents for 1919 statistics in detail for the state as a whole 
and for each industry that can be shown without the disclosure of indi¬ 
vidual operations.”
