In treating of this branch of natural history, we will first take man--the true curly-head, flab-nosed, pouch-mouthed negro--not the Wahuma. [2] They are well distributed all over these latitudes, but are not found anywhere in dense communities. Their system of government is mostly of the patriarchal character. Some are pastorals, but most are agriculturalists; and this difference, I believe, originates solely from want of a stable government, to enable them to reap what they produce; for where the negro can save his cattle, which is his wealth, by eating grain, he will do it. In the same way as all animals, whether wild or tame, require a guide to lead their flocks, so do the negroes find it necessary to have chiefs over their villages and little communities, who are their referees on all domestic or political questions. They have both their district and their village chiefs, but, in the countries we are about to travel over, no kings such as we shall find that the Wahuma have. The district chief is absolute, though guided in great measure by his "grey-beards," who constantly attend his residence, and talk over their affairs of state. These commonly concern petty internal matters; for they are too selfish and too narrow-minded to care for anything but their own private concerns. The grey-beards circulate the orders of the chief amongst the village chiefs, who are fined when they do not comply with them; and hence all orders are pretty well obeyed. One thing only tends to disorganise the country, and that is war, caused, in the first instance, by polygamy, producing a family of half-brothers, who, all aspiring to succeed their father, fight continually with one another, and make their chief aim slaves and cattle; whilst, in the second instance, slavery keeps them ever fighting and reducing their numbers. The government revenues are levied, on a very small scale, exclusively for the benefit of the chief and his grey-beards. For instance, as a sort of land-tax, the chief has a right to drink free from the village brews of pombe (a kind of beer made by fermentation), which are made in turn by all the villagers successively. In case of an elephant being killed, he also takes a share of the meat, and claims one of its tusks as his right; further, all leopard, lion, or zebra skins are his by right. On merchandise brought into the country by traders, he has a general right to make any exactions he thinks he has the power of enforcing, without any regard to justice or a regulated tariff. This right is called Hongo, in the plural Mahongo. Another source of revenue is in the effects of all people condemned for sorcery, who are either burnt, or speared and cast into the jungles, and their property seized by the grey-beards for their chief.
