I observed at Chibanda's a few green mushrooms, which, on being peeled, showed a pink, fleshy inside; they are called "chisimba;" and only one or two are put into the mortar, in which the women pound the other kinds, to give relish, it was said, to the mass: I could not ascertain what properties chisimba had when taken alone; but mushroom diet, in our experience, is good only for producing dreams of the roast beef of bygone days. The saliva runs from the mouth in these dreams, and the pillow is wet with it in the mornings. These Babisa are full of suspicion; everything has to be paid for accordingly in advance, and we found that giving a present to a chief is only putting it in his power to cheat us out of a supper. They give nothing to each other for nothing, and if this is enlargement of mind produced by commerce, commend me to the untrading African! Fish now appear in the rivulets. Higher altitudes have only small things, not worth catching. An owl makes the woods resound by night and early morning with his cries, which consist of a loud, double-initial note, and then a succession of lower descending notes. Another new bird, or at least new to me, makes the forests ring. When the vultures see us making our sheds, they conclude that we have killed some animal; but after watching awhile, and seeing no meat, they depart. This is suggestive of what other things prove, that it is only by sight they are guided.[47] With respect to the native head-dresses the colouring-matter, "nkola," which seems to be camwood, is placed as an ornament on the head, and some is put on the bark-cloth to give it a pleasant appearance. The tree, when cut, is burned to bring out the strong colour, and then, when it is developed, the wood is powdered. The gum-copal trees now pour out gum where wounded, and I have seen masses of it fallen on the ground. _26th January, 1867._--Went northwards along the Movushi, near to its confluence with Chambeze, and then took lodging in a deserted temporary village. In the evening I shot a poku, or tsebula, full-grown male. It measured from snout to insertion of tail, 5 feet 3 inches; tail, 1 foot; height at withers, 3 feet; circumference of chest, 5 feet; face to insertion of horns, 9-1/2 inches; horns measured on curve, 16 inches. Twelve rings on horns, and one had a ridge behind, 1/2 inch broad, 1/2 inch high, and tapering up the horn; probably accidental. Colour: reddish-yellow, dark points in front of foot and on the ears, belly nearly white. The shell went through from behind the shoulder to the spleen, and burst on the other side, yet he ran 100 yards. I felt very thankful to the Giver of all good for this meat. _27th January, 1867._--A set-in rain all the morning, but having meat we were comfortable in the old huts. In changing my dress this morning I was frightened at my own emaciation.
