Similarly, though in the upper regions the climate is delicious, the missionaries could not keep themselves alive, but died of privation, hardship, and fatigue. Chapter VIII. A Visit to Banza Chisalla, Boma, at the head of the Congo delta, the great dépôt between the interior and the coast, owes its existence wholly to "the cruel trade Which spoils unhappy Afric of her sons." Father Merolla (1682), who visited it from "Angoij," our "Cabinda," speaks of it as a pretty large island, tributary to the Mani-Congo, extremely populous, well supplied with provisions, and outlaid by islets belonging to the Count of Sonho. Tuckey's Embomma was an inland banza or town, and the site of the factories was called Market Point; the Expedition map and the hydrographic chart term it Loombee, the latter being properly the name of a large quitanda (market) lying two miles to the north-west. Early in the present century it is described as a village of a hundred huts, opposite which trading vessels anchored under charge of the "Fuka or king's merchant;" no market was held there, lest, in case of dispute, the royal person might suffer. Although the main features of our maps are still correct, there have been great changes in the river-bed between Porto da Lenha and Boma, especially about the latter place, which should be transferred from its present site to Lumbi. The broad Chisalla Creek, which Mr. Maxwell calls Logan, between the northern bank and the island "Booka Embomma," is now an arm only 200 feet wide. In fact all the bank about Boma, like the lower delta, urgently calls for re-surveying. This part of the river belongs to the "Rei dos Reis," Nessalla, under whom are some ten chief officers called "kings," who buy and sell; indeed, Africa knows no other. The title is prostituted throughout the West Coast, but it is nowhere so degraded as in the Congo regions; the whites abuse it to flatter the vanity of the astute negro, who accepts it with a view to results--a "king- dash" must, of course, be greater than that of a subject. Every fellow with one black coat becomes a "preese" (prince), and if he has two he styles himself a "king." Without permission of the "King of Kings" we could obtain neither interpreter, canoe, nor crew; a visit to Banza Chisalal was therefore necessary and, as it would have been vain to ask anything empty-handed, I took with me a fine spangled cloak, a piece of chintz, and a case of ship's rum, the whole worth £9.
