Abstract
As the result of recent explorations by Lieutenant Fromm in the southern part of German East Africa, it appears probable that the difficulties which beset navigation on the Rufiji and Rovuma rivers are not so serious as has hitherto been supposed. The resources of the country traversed by these rivers are reported to consist mainly of india-rubber in the forests. An examination of a coalfield reported by Arabs as existing on a tributary of the Rovuma showed that the valuable coal-seams were practically confined to the Portuguese side of the frontier.
