Note 65 — Chapter IX · THE NATIONAL INDUSTRY OF SOUTHERN NIGERIA
Reading edition
The exception is the machine erected at the Brass River in 1877 (by the Count de Cardi, I believe) and used to this day by the firm which has the principal trade of this district. It can produce, I believe, forty or fifty bags of clean kernels per day of ten hours. It would require 600 or 700 pairs of hands to give this result in the same time.
