Dangerous state of Dr. Livingstone. _1st February, 1873._--Waiting for the scouts. They return unsuccessful--forced to do so by hunger. They saw a very large river flowing into the Lake, but did not come across a single soul. Killed our last calf, and turn back for four hard days' travel to Chituñkuè's. I send men on before us to bring food back towards us. _2nd February, 1873._--March smartly back to our camp of 28th ult. The people bear their hunger well. They collect mushrooms and plants, and often get lost in this flat featureless country. _3rd February, 1873._--Return march to our bridge on the Lofu, five hours. In going we went astray, and took six hours to do the work of five. Tried lunars in vain. Either sun or moon in clouds. On the Luéna. _4th February, 1873._--Return to camp on the rivulet with much _Methonica gloriosa_ on its banks. Our camp being on its left bank of 26th. It took long to cross the next river, probably the Kwalé, though the elephants' footprints are all filled up now. Camp among deserted gardens, which afford a welcome supply of cassava and sweet potatoes. The men who were sent on before us slept here last night, and have deceived us by going more slowly without loads than we who are loaded. _5th February, 1873._--Arrived at Chituñkuè's, crossing two broad deep brooks, and on to the Malalenzi, now swollen, having at least 200 yards of flood and more than 300 yards of sponge. Saluted by a drizzling shower. We are now at Chituñkuè's mercy. We find the chief more civil than we expected. He said each chief had his own land and his own peculiarities. He was not responsible for others. We were told that we had been near to Matipa and other chiefs: he would give us guides if we gave him a cloth and some powder.
