As the object of the royal taboos is to isolate the king from all sources of danger, their general effect is to compel him to live in a state of seclusion, more or less complete, according to the number and stringency of the rules he observes. Now of all sources of danger none are more dreaded by the savage than magic and witchcraft, and he suspects all strangers of practising these black arts. To guard against the baneful influence exerted voluntarily or involuntarily by strangers is therefore an elementary dictate of savage prudence. Hence before strangers are allowed to enter a district, or at least before they are permitted to mingle freely with the inhabitants, certain ceremonies are often performed by the natives of the country for the purpose of disarming the strangers of their magical powers, of counteracting the baneful influence which is believed to emanate from them, or of disinfecting, so to speak, the tainted atmosphere by which they are supposed to be surrounded. Thus, when the ambassadors sent by Justin II., Emperor of the East, to conclude a peace with the Turks had reached their destination, they were received by shamans, who subjected them to a ceremonial purification for the purpose of exorcising all harmful influence. Having deposited the goods brought by the ambassadors in an open place, these wizards carried burning branches of incense round them, while they rang a bell and beat on a tambourine, snorting and falling into a state of frenzy in their efforts to dispel the powers of evil. Afterwards they purified the ambassadors themselves by leading them through the flames. In the island of Nanumea (South Pacific) strangers from ships or from other islands were not allowed to communicate with the people until they all, or a few as representatives of the rest, had been taken to each of the four temples in the island, and prayers offered that the god would avert any disease or treachery which these strangers might have brought with them. Meat offerings were also laid upon the altars, accompanied by songs and dances in honour of the god. While these ceremonies were going on, all the people except the priests and their attendants kept out of sight. Amongst the Ot Danoms of Borneo it is the custom that strangers entering the territory should pay to the natives a certain sum, which is spent in the sacrifice of buffaloes or pigs to the spirits of the land and water, in order to reconcile them to the presence of the strangers, and to induce them not to withdraw their favour from the people of the country, but to bless the rice-harvest, and so forth. The men of a certain district in Borneo, fearing to look upon a European traveller lest he should make them ill, warned their wives and children not to go near him. Those who could not restrain their curiosity killed fowls to appease the evil spirits and smeared themselves with the blood. "More dreaded," says a traveller in Central Borneo, "than the evil spirits
