On the fourth day I despatched Shaw with two more soldiers, to see what had become of Kingaru and the two Mabrukis. Towards night he returned completely prostrated, with a violent attack of the mukunguru, or ague; but bringing the missing soldiers, who were thus left to report for themselves. With most thankful hearts did we quit our camp, where so much anxiety of mind and fretfulness had been suffered, not heeding a furious rain, which, after drenching us all night, might have somewhat damped our ardor for the march under other circumstances. The road for the first mile led over reddish ground, and was drained by gentle slopes falling east and west; but, leaving the cover of the friendly woods, on whose eastern margin we had been delayed so long, we emerged into one of the savannahs, whose soil during the rain is as soft as slush and tenacious as thick mortar, where we were all threatened with the fate of the famous Arkansas traveller, who had sunk so low in one of the many quagmires in Arkansas county, that nothing but his tall "stove-pipe" hat was left visible. Shaw was sick, and the whole duty of driving the foundering caravan devolved upon myself. The Wanyamwezi donkeys stuck in the mire as if they were rooted to it. As fast as one was flogged from his stubborn position, prone to the depths fell another, giving me a Sisyphean labour, which was maddening trader pelting rain, assisted by such men as Bombay and Uledi, who could not for a whole skin's sake stomach the storm and mire. Two hours of such a task enabled me to drag my caravan over a savannah one mile and a half broad; and barely had I finished congratulating myself over my success before I was halted by a deep ditch, which, filled with rain-water from the inundated savannahs, had become a considerable stream, breast-deep, flowing swiftly into the Makata. Donkeys had to be unloaded, led through a torrent, and loaded again on the other bank--an operation which consumed a full hour. Presently, after straggling through a wood clump, barring our progress was another stream, swollen into a river. The bridge being swept away, we were obliged to swim and float our baggage over, which delayed us two hours more. Leaving this second river-bank, we splashed, waded, occasionally half-swimming, and reeled through mire, water-dripping grass and matama stalks, along the left bank of the Makata proper, until farther progress was effectually prevented for that day by a deep bend of the river, which we should be obliged to cross the next day. Though but six miles were traversed during that miserable day, the march occupied ten hours.
