 TYPICAL PHOSPHATE MINES
 Polk County. Florida
A PHOSPHATE mine. with its giant drag-lines removing the top
 soil and its high pressure water streams cutting into the phosphate
beds as though they were so much putty, presents an unusual picture from
the air. In this section of Florida. we encounter many such picturesque
mines, and cannot help but be impressed by their geometric symmetry and
tremendous size.
