Our system of progress was to begin each day with Frank leading the Expedition overland to a camp at the head of some inlet, cove, or recess, near rapids or falls, where, with the older men, women, and children, he constructed a camp; the working party, consisting of the younger men, returning to assist me with the canoes down to the new camp. Anxious for the safety of the people, I superintended the river work myself, and each day led the way in the boat. On approaching rapids I selected three or four of the boat’s crew (and always Uledi, the coxswain), and clambered along the great rocks piled along the base of the steeply sloping hills, until I had examined the scene. If the rapids or fall were deemed impassable by water, I planned the shortest and safest route across the projecting points, and then, mustering the people, strewed a broad track with bushes, over which, as soon as completed, we set to work to haul our vessels beyond the dangerous water, when we lowered them into the water, and pursued our way to camp, where Frank would be ready to give me welcome, and such a meal as the country afforded. At Gamfwé’s the natives sold us abundance of bread, or rolls of pudding, of cassava flour, maize, cassava leaves, water-cresses, and a small Strychnos fruit and, for the first time, lemons. Fowls were very dear, and a goat was too expensive a luxury in our now rapidly impoverishing state. _April 8._—On the 8th we descended from Gamfwé’s to “Whirlpool Narrows,” opposite Umvilingya. When near there we perceived that the eddy tides, which rushed up river along the bank, required very delicate and skilful manœuvring. I experimented on the boat first, and attempted to haul her by cables round a rocky point from the bay near Whirlpool Narrows. Twice they snapped ropes and cables, and the second time the boat flew up river, borne on the crests of brown waves, with only Uledi and two men in her. Presently she wheeled into the bay, following the course of the eddy, and Uledi brought her in-shore. The third time we tried the operation with six cables of twisted rattan, about 200 feet in length, with five men to each cable. The rocks rose singly in precipitous masses 50 feet above the river, and this extreme height increased the difficulty and rendered footing precarious, for furious eddies of past pages had drilled deep circular pits, like ovens, in them, 4, 6, even 10 feet deep. However, with the utmost patience we succeeded in rounding these enormous blocks, and hauling the boat against the uneasy eddy tide to where the river resumed its natural downward flow. Below this, as I learned, were some two miles of boisterous water; but mid-river, though foaming in places, was not what we considered dangerous. We therefore resolved to risk it in mid-stream, and the boat’s crew, never backward when they knew what lay in front of them, manned the boat, and in fifteen minutes we had taken her into a small creek near Umvilingya’s
