But the motives that actuate many in England, both in public and private life, are much more noble than the world gives them credit for.
Seeing, then, that we were not yet arrived at "the good time coming," and that it was quite impossible to take the "Pioneer" down to the sea till the floods of December, we made arrangements to screw the "Lady Nyassa" together; and, in order to improve the time intervening, we resolved to carry a boat past the Cataracts a second time, sail along the eastern shore of the Lake, and round the northern end, and also collect data by which to verify the information collected by Colonel Rigby, that the 19,000 slaves, who go through the Custom-house of Zanzibar annually, are chiefly drawn from Lake Nyassa and the Valley of the Shire.
Our party consisted of twenty natives, some of whom were Johanna men, and were supposed to be capable of managing the six oxen which drew the small wagon with a boat on it.

A team of twelve Cape oxen, with a Hottentot driver and leader, would have taken the wagon over the country we had to pass through with the greatest ease; but no sooner did we get beyond the part of the road already made, than our drivers encountered obstructions in the way of trees and gullies, which it would have been a waste of time to have overcome by felling timber and hauling out the wagon by block and tackle purchases.

The Ajawa and Manganja settled at Chibisa's were therefore sent for, and they took the boat on their shoulders and carried it briskly, in a few days, past all the Cataracts except one; then coming to a comparatively still reach of the river, they took advantage of it to haul her up a couple of miles.

The Makololo had her then entirely in charge; for, being accustomed to rapids in their own country, no better boatmen could be desired.

The river here is very narrow, and even in what are called still places, the current is very strong, and often obliged them to haul the boat along by the reeds on the banks, or to hand a tow-rope ashore.
