Part 2 — NIGERIA-NORTHERN PROVINCES (continued 2)

Reading edition

A second quality of silk is that called “Tsamian doka,” and is obtained from the cocoon masses produced by the larvæ of Anaphe Moloneyi, which are found in the same locality, feeding upon the “Bokin doka” tree, which has been determined to be a species of Macrolobium. Several hundred worms congregate together and form a solid mass of pale brown tubular cocoons upon the bark of the tree, covering the outer surface with a whitish envelope of silk. This silk is treated in the same manner as the other, but, after boiling and washing, does not become white. Two other species, which are used for the same purpose, are called “Tsamian fakali” and “Tsamian bauri,” and feed on another species of Macrolobium and a Ficus respectively. They produce inferior kinds of silk.

Much interest is attached to these Anaphe silks, which, in recent years, have been developed in the German Colonies of East Africa, especially, on a commercial scale. It is reported that, just previous to the declaration of war, German agents in British West Africa made endeavours to obtain as much of the wild silk as possible from Nigeria. Plantations of a species of Bridelia, the common food plant of Anaphe infracta, were made in the late German Colonies, and special machinery was in use there for the production of a commercial silk.

The following figures give the values of the chief exported products from Nigeria as a whole, from 1913 to 1919:—
