The sanction of the tapu is superstitious; and the punishment of infraction either a wasting or a deadly sickness. A slow disease follows on the eating of tapu fish, and can only be cured with the bones of the same fish burned with the due mysteries. The cocoa-nut and breadfruit tapu works more swiftly. Suppose you have eaten tapu fruit at the evening meal, at night your sleep will be uneasy; in the morning, swelling and a dark discoloration will have attacked your neck, whence they spread upward to the face; and in two days, unless the cure be interjected, you must die. This cure is prepared from the rubbed leaves of the tree from which the patient stole; so that he cannot be saved without confessing to the Tahuku the person whom he wronged. In the experience of my informant, almost no tapu had been put in use, except the two described: he had thus no opportunity to learn the nature and operation of the others; and, as the art of making them was jealously guarded amongst the old men, he believed the mystery would soon die out. I should add that he was no Marquesan, but a Chinaman, a resident in the group from boyhood, and a reverent believer in the spells which he described. White men, amongst whom Ah Fu included himself, were exempt; but he had a tale of a Tahitian woman, who had come to the Marquesas, eaten tapu fish, and, although uninformed of her offence and danger, had been afflicted and cured exactly like a native.
Doubtless the belief is strong; doubtless, with this weakly and fanciful race, it is in many cases strong enough to kill; it should be strong indeed in those who tapu their trees secretly, so that they may detect a depredator by his sickness. Or, perhaps, we should understand the idea of the hidden tapu otherwise, as a politic device to spread uneasiness and extort confessions: so that, when a man is ailing, he shall ransack his brain for any possible offence, and send at once for any proprietor whose rights he has invaded. ‘Had you hidden a tapu?’ we may conceive him asking; and I cannot imagine the proprietor gainsaying it; and this is perhaps the strangest feature of the system—that it should be regarded from without with such a mental and implicit awe, and, when examined from within, should present so many apparent evidences of design.
