The most conspicuous feature of the vegetation was the abundance of fine fan-leaved palms (Borassus flabelliformis), from the leaves of which are constructed the strong and durable water-buckets in general use, and which are much superior to those formed from any other species of palm. From the same tree, palm-wine and sugar are made, and the common thatch for houses formed of the leaves lasts six or seven years without removal.
