The capacity of the mill is 100 barrels of flour, 250 bushels of meal and 250 bushels of corn per day. The mills do a large exchange and merchant work.

Lee secretary and treasurer." Stack & Beasley 1902

Overhead Bridge
The overhead bridge linked Church Street and Winchester Avenue above the Seaboard Railroad tracks. The business in the center of this picture is Henderson Roller Mill.
Apparently, grain cars delivered the raw material (wheat) for processing and the finished product (flour) was loaded back onto rail cars to the left for distribution across the country.

The overhead bridge was torn down in the 1950s 
when the new Skyway Bridge was opened for traffic.
