The 6th November saw us betimes in the ill-omened Forest, that divided us from the Unyanyembe district; it is a thin growth of gum-trees, mimosas, and bauhinias, with tiers, earth-waves, and long rolling lines of tawny-yellow hill--mantled with umbrella-shaped trees, and sometimes capped with blocks and boulders--extending to a considerable distance on both sides. The Sultan of Kigwa, one Manwa, has taken an active part in the many robberies and murders which have rendered this forest a place of terror, and the Arabs have hitherto confined themselves to threats, though a single merchant complains that his slave-caravans have at different times lost fifty loads of cloth. Manwa is aided and counselled by Mansur, a Coast-Arab, who, horse-whipped out of the society of his countrymen at Kazeh, for drunken and disorderly conduct, has become a notorious traitor. Here also Msimbira, a Sultan of the Wasukuma, or Northern Wanyamwezi, who has an old and burning hatred against the Arabs, sends his plundering parties. On the 6th November the Baloch set out at 1 A.M., we followed at 2.15 A.M.: they had been prevented from obtaining beads on false pretences, consequently they showed temper, and determined to deny their escort. Their beards were now in my hand, they could neither desert nor refuse to proceed, but they desired to do me a harm, and they did it. During the transit of the forest, an old porter having imprudently lagged behind, was clubbed and cruelly bruised by three black Mohawks, who relieved him of his load, a leathern portmanteau, containing clothes, umbrellas, books, ink, journals, and botanical collections. I afterwards heard that the highwaymen had divided their spoils in the forest, and that separating into two parties, they had taken the route homewards. On the way, however, they were seized by a plundering expedition sent by Kitambi, the Sultan of Uyuwwi, a district half a day’s march N.E. from Kazeh. The delict was flagrant; the head of one robber at once decorated the main entrance of Kitambi’s village, but the other two escaped Jeddart-justice with their share of the plunder to his mortal enemy Msimbira. A present of a scarlet waistcoat and four domestics recovered our clothes from Kitambi; but Msimbira, threatening all the penalties of sorcery, abused, plundered, and expelled Masud ibn Musallam el Wardi, an old Arab merchant, sent to him from Unyanyembe for the purpose of recovering the books, journals, and collections. The perpetual risk of loss discourages the traveller in these lands; he never knows at what moment papers which have cost him months of toil may be scattered to the winds. As regards collections, future explorers are advised to abandon the hope of making them on the march upwards, reserving their labour for the more leisurely return. The precautions with which I prefaced our down-march may not be useless as suggestions. My field and sketch-books were entrusted to an
