Rice farming in the early history of the mill was without any mechanical equipment. The land was
tilled and
harrowed using
mule-drawn implements. After laying
seed by hand in the fields, small
levees were built with shovels of sufficient height to hold water at a depth of 1 to 1 ½ inches. Water was brought from the
Bayou Teche (up to three miles away) using an irrigation system built specifically for that purpose. Water
pumps pulled water from the
bayou to an elevated trough twelve feet above the bayou that angled down over 700 feet to a street-level
flume, using gravity to drive the water to the fields. The flume traversed over a section of the city of
New Iberia, being routed under streets using salvaged steam boilers. Two pumps were positioned at the bayou, one operational and one backup, driven by
Fairbanks-Morse cold-start crude oil engines, each with two 9" pistons, adapted from ice house pumps that drove the refrigeration equipment, and capable of pumping 1100 to 1300 gallons per minute. Initial flooding of the fields took about a week, but water had to be continually pumped to keep the fields under water until the sprouts grew above the ground. At this point, pumping was stopped, and the levees were opened with shovels to drain the water to avoid injury to the young stalks. When the stalks became firm, the fields were again flooded until the rice was almost mature. Rice was planted in the spring (around
Easter) and harvested in August. Growing time was about 150 days initially, but newer varieties of rice reduced this time to about 120 days. Irrigation and harvesting by hand required from 20 to 40 workers. Rice on its stalks was cut and assembled by hand into shocks, and allowed to dry in the field for 2 to 3 days. The harvested rice was threshed in the field by a tractor-powered
thresher, then transported by wagon to the mill, a distance of up to several miles. At the mill the rice underwent the completion of the drying process by two to three passes in a forced air elevated chimney dryer, to reduce its moisture content from about 25% to 18% to facilitate the milling process. == Mechanical farming ==
