The net earnings of the
planters were increased in a still greater proportion than this, for the
work-seasons in the two crops could be so dovetailed that a single gang
might cultivate both staples.

Indigo grew best in the light, dry soil so common on the coastal plain.
From seed sown in the early spring the plant would reach its full growth,
from three to six feet high, and begin to bloom in June or early July. At
that stage the plants were cut off near the ground and laid under water in
a shallow vat for a fermentation which in the course of some twelve hours
took the dye-stuff out of the leaves. The solution then drawn into another
vat was vigorously beaten with paddles for several hours to renew and
complete the foaming fermentation. Samples were taken at frequent intervals
during the latter part of this process, and so soon as a blue tinge became
apparent lime water, in carefully determined proportions, was gently
stirred in to stop all further action and precipitate the "blueing.
