Derris Root Industry

AS a result of investigations made by an officer of the Commonwealth Dept, of Trade and Customs, South Seas planters have been advised by the Gov ernment that there is little purpose in cultivating Derris roots in the Islands, as an alternative crop. Derris has a limited commercial market on account of its Retenone content.

The authorities point out that the two main difficulties in marketing are lack of knowledge of its toxic value, and exces sive shipment cost. Another problem is the difficulty of economical milling—the roots have first to be fed to a cutting ma chine before being placed in the grinding mill, where close supervision is necessary.

At present, Straits Settlement is the main producer. The average return is about £l5O sterling per ton f.o.b.
