phosphate 
The following statement regarding the production of phosphate in 
Florida during 1920 was issued by the State Geological Survey, May 9, 
1921:* 
“The phosphate industry of Florida in 1920 far exceeded that of any 
previous year, both in point of production and of value. This fact is 
brought out by statistics collected in co-operation with the United States 
Geological Survey and recently tabulated. The total shipment of phos¬ 
phate from Florida during 1920 was 3,369,384 long tons, as compared 
with 1,660,200 long tons in 1919. This is an increase of 1,709,184 tons, 
which is more than twice the production for the previous year. The 
year 1913 is referred to as the “peak” year of the phosphate industry
