ONE: What so proudly we hailed at the twilight's last gleaming?"Both the boys were greatly interested in the various processes of work that were visible on shore. Groups of men were to be seen cutting reeds for fuel, or for the roofs of houses, where they make a warm thatch that keeps out the rain and snow. Other groups were gathering cotton, hemp, millet, and other products of the earth; and at several points there were men with blue hands, who were extracting indigo from the plant which[Pg 346] produces it. The plant is bruised and soaked in water till the coloring-matter is drawn out; the indigo settles to the bottom of the tub, and the water is poured off; and after being dried in the sun, the cake forms the indigo of commerce. In many places there were little stages about thirty feet high, and just large enough at the top for one man, who worked there patiently and alone. Frank could not make out the employment of these men, and neither could Fred. After puzzling awhile over the matter, they referred it to Doctor Bronson.
