The assertion may seem strange, yet it is none the less true, that in all the tribes we have visited we never saw a really black person. Different shades of brown prevail, and often with a bright bronze tint, which no painter, except Mr. Angus, seems able to catch. Those who inhabit elevated, dry situations, and who are not obliged to work much in the sun, are frequently of a light warm brown, "dark but comely." Darkness of colour is probably partly caused by the sun, and partly by something in the climate or soil which we do not yet know. We see something of the same sort in trout and other fish which take their colour from the ponds or streams in which they live. The members of our party were much less embrowned by free exposure to the sun for years than Dr. Livingstone and his family were by passing once from Kuruman to Cape Town, a journey which occupied only a couple of months. We encamped on the Kalomo, on the 1st of October, and found the weather very much warmer than when we crossed this stream in August. At 3 p.m. the thermometer, four feet from the ground, was 101 degrees in the shade; the wet bulb only 61 degrees: a difference of 40 degrees. Yet, notwithstanding this extreme dryness of the atmosphere, without a drop of rain having fallen for months, and scarcely any dew, many of the shrubs and trees were putting forth fresh leaves of various hues, while others made a profuse display of lovely blossoms. Two old and very savage buffaloes were shot for our companions on the 3rd October. Our Volunteers may feel an interest in knowing that balls sometimes have but little effect: one buffalo fell, on receiving a Jacob's shell; it was hit again twice, and lost a large amount of blood; and yet it sprang up, and charged a native, who, by great agility, had just time to climb a tree, before the maddened beast struck it, battering- ram fashion, hard enough almost to have split both head and tree. It paused a few seconds--drew back several paces--glared up at the man--and then dashed at the tree again and again, as if determined to shake him out of it. It took two more Jacob's shells, and five other large solid rifle-balls to finish the beast at last. These old surly buffaloes had been wandering about in a sort of miserable fellowship; their skins were diseased and scabby, as if leprous, and their horns atrophied or worn down to stumps--the first was killed outright, by one Jacob's shell, the second died hard. There is so much difference in the tenacity of life in wounded animals of the same species, that the inquiry is suggested where the seat of life can be?--We have seen a buffalo live long enough, after a large bullet had passed right through the heart, to allow firm adherent clots to be formed in the two holes.
