The general bearings of the law of tapu may be inferred from the sense of the word, which signifies prohibition. The system of tapu is therefore a law of prohibition, and, when stripped of the extravagances into which it often deteriorates, it is seen to be a very excellent system, and one that answers the purpose of a more elaborate code of laws. In countries where an organized government is employed the tapu is needless, and we find that even in those parts of the earth where it was once the only restrictive law it has fallen into disuse since regular government has been introduced. Were it not for the law of tapu, an absolute anarchy would prevail in most parts of Polynesia, the tapu being the only guardian of property and morality. In order that it may be enforced on the people, the terrors of superstition are called into play, and, in the absence of secular law, the spiritual powers are evoked. Unprotected by the tapu, property could not exist: protected by it, the most valued and coveted articles are safer than they would be in England or America despite the elaborate legal system that secures to every man that which is his own. In New Zealand, when a man has cultivated a field of kumeras, or sweet potatoes, he needs no fence and no watchman. He simply sends for the tohunga, who lays the tapu on the field; and from that moment no one save the owner will venture within its boundaries. Sometimes a canoe is hauled up on the beach, and must be left there for some time unwatched. The owner need not trouble himself about securing his vessel. He has the tapu mark placed upon it, and the boat is accordingly held sacred to all except its possessor. Similarly, if a native boat-builder fixes on a tree which he thinks can be made into a canoe, he places the tapu on it, and knows that no one but himself will dare to cut it down. The mark of tapu in this case is almost invariably the removal of a strip of bark round the trunk of the tree. Then the system of tapu is the only guardian of morals. It has been already mentioned that an extreme laxity in this respect prevails among the unmarried girls. But as soon as a girl is married she becomes tapu to all but her husband, and any one who induces her to become unfaithful must pay the penalty of the tapu if the delinquents be discovered. Nor is the tapu restricted to married women. It is also extended to young girls when they are betrothed; and any girl on whom the tapu has thus been laid is reckoned as a married woman. It will be seen, therefore, that the principle of the tapu is a good one, and that it serves as protection both to property and morals. There are, of course, many instances where this system has run into extravagances, and where, instead of a protection, it has developed into a tyranny.
