+597+. A priest also may carry taboo infection on his person. In Ezekiel's scheme of ritual organization it is ordered that when the priest, having offered sacrifice, goes forth into the outer court where the people are, he shall put off the garments in which he ministered and lay them in a sacred place, and put on other garments, lest some one touching him should be made ritually unclean, that is taboo, forbidden to mingle with his fellows or to do his ordinary work for a certain time (generally till the evening).[962] In many regions there have been and are numerous restrictions on priests, some of which are in their own interests (to preserve their ritual purity), some in the interests of others (to guard them against the infection of taboo).[963] Other quasi-official or devoted persons (as, for example, the Hebrew Nazirite[964]) were subject to restrictions of food. Strangers, who in a primitive period were frequently put to death, in a more humane period were subjected to purifying processes in order to remove the taboo infection that might cling to them.[965] +598+. _Industrial taboos._ The customs of certain Polynesian chiefs, described above, cannot be said to aid industry, but there are taboo usages designed to protect and further popular occupations. These doubtless have a natural nonmagical basis--the necessity of making good crops and protecting private property would be recognized everywhere, and would call forth legal enactments; but it was inevitable, in certain communities, that such enactments should be strengthened by supernatural sanctions such as those offered by the conception of taboo. +599+. Protective arrangements of this sort abound in Oceania and Indonesia. In Samoa the sweet-potato fields are taboo till the crop is gathered.[966] Hawaiian fisheries are protected by the simple device of forbidding the taking of certain fish at certain seasons; here the economic motive is obvious, but taboo penalties are annexed.[967] During planting time in New Zealand all persons employed in the work were taboo for other occupations and obliged to give all their time to the planting; and the same rule held for hunting and fishing.[968] The Borneo Kayans refrain from their usual occupations during planting, harvesting, and the search for camphor.[969] Similar restrictions, of an elaborate kind, are in force in Sumatra,[970] and in Assam.[971]
